New Concepts in Jet Planes – Commercial Applications

Posted by: admin  /  Category: Aviation Airplanes

Everyone has a dream to fly in private jet planes. Now it becomes a status symbol to express that you’re one of the wealthiest people. These days’ customers are more interested in buying these planes. Many famous personalities are purchasing large sized jets. Interested buyers are always searching for aircraft’s for sale. But before finalizing any deal with these service providers, it’s better to search for other services and collect all the details regarding these sales. Compare them with each other and select the one which offers numerous affordable deals to the buyers. Many leading newspapers and magazines are regularly publishing classifieds of aircraft for sale.

All leading jet manufacturing companies are frequently launching new editions of jet planes. In the range of new jets, seating arrangements will be removed completely and other facilities will be put at that place. Some models of jets are having amenities like bedroom, bar, dining table and dance floor. There are some jet plane which are providing seating arrangements for around twenty five passengers. To make these planes homely, manufacturers add entertainment system such as television set, chandeliers and other accessories to these jet aircrafts. Before getting aircraft for sale, make sure that you will done a proper homework. Always check out for the conditions of the aircraft like its shape, interior etc. In these sales, all listed jets are available with detailed information. Check the log books of all types such as maintenance log, certificates, licenses etc.

Before paying huge amount for the jet planes, make sure that all the essential documents are legal. Selecting these kinds of sales is quite difficult. Hence, you can take help of experts who are master in this field. Planes which are having interior and exterior in well maintained condition are considered as the safe planes. At least take a short test flight of the desire aircraft. Customers who are not able to buy brand new aircraft’s are ready to pay for used or second hand planes. Sometimes ads of aircraft for sale look attractive and interesting, but check out for all the conditions thoroughly. Most jet owners rent these aircraft’s and earn high amount of profit. Even, passengers are also interested in these types of deals.

The Voisin Biplane

Posted by: admin  /  Category: Uncategorized

A single glance at the Voisin Biplane reveals exactly what one would expect of a vintage aircraft: a somewhat ungainly design with dual, fabric-covered wings; a propeller; an aerodynamic surface protruding ahead of its airframe; and a boxy, kite-resembling tail. But, by 1907 standards, it had been considered “advanced.”

Its designer, Gabriel Voisin, son of a provincial engineer, was born in Belleville, France, in 1880, initially demonstrating mechanical and aeronautical aptitude through his boat, automobile, and kite interests. An admirer of Clement Ader, he trained as an architect and draftsman at the Ecole des Beaux-Arts in Lyon, and was later introduced to Ernest Archdeacon, a wealthy lawyer and aviation enthusiast, who subsequently commissioned him to design a glider.

Using inaccurate and incomplete drawings of the Wright Brothers’ 1902 glider published in L’Aerophile, the Aero-Club’s journal, Voisin constructed an airframe in January of 1904 which only bore a superficial resemblance to its original. Sporting dual wings subdivided by vertical partitions, a forward elevating plane, and a two-cell box-kite tail, it was devoid of the Wright-devised wing-warping method, and therefore had no means by which lateral control could be exerted. Two-thirds the size of the original, it was 40 pounds lighter.

Supported by floats and tethered to a Panhard-engined racing boat, the glider attempted its first fight from the Seine River on June 8, 1905, as described by Voisin himself. “Gradually and cautiously, (the helmsman) took up the slack of my towing cable…” he had written. “I had the controls ready. I waited for a time and then I applied the elevator.”

Virtually catapulted skyward by the air suddenly exerting its effects on its airfoils, it ascended as high as the river-lining poplar trees, but the unstable glider, unable to be controlled about its lateral axis, almost as abruptly nosed toward the water after a 50-foot, bell-curve trajectory, plunging below the surface and briefly submerging its pilot.

Despite the unsuccessful attempt, Louis Bleriot, witnessing the event, subsequently approached Voisin to build a second airframe for him.

Based upon the first, it featured a reduced wingspan with greater curvature and sloping, vertical side panels, and a single-cell tail, but it suffered a similar fate: covering some 100 feet during its July 18 test flight, it side-slipped immediately after taking to the air, once again plunging into the river.

Despite its inherent lack of roll control, it nevertheless served as the foundation upon which subsequent Voisin and other early European designs were based.

Voisin and Bleriot, briefly forming a collaborative partnership, produced equally unsuccessful aircraft due, in great part, to the latter’s radical, ever-changing ideas. The Bleriot III, for instance, sported elliptical wings and was powered by a 24-hp Antoinette engine, but failed to achieve sufficient lift when fitted with floats. Reconfigured as a land machine with a wheeled undercarriage and a second engine, it collided with a rock during its acceleration run, bouncing across a ditch, nosing over, and abruptly ending its travel-along with the Voisin-Bleriot collaboration.

Gabriel Voisin, buying out Bleriot’s interest in 1906, reformed the company with brother, Charles, creating “Appareils d’Aviation Les Freres Voisin” or “Voisin Brothers Flying Machines,” establishing, as an extension of the Bleriot venture, the first European aircraft manufacturer in Billancourt, with financial backing from Enest Archdeacon and three others. The aviation industry was, in effect, launched.

The Gabriel and Charles Voisin team ironically mirrored their Orville and Wilbur Wright Brothers counterparts across the Atlantic. Gabriel, for example-the older of the two and Chief Engineer-provided most of the impetus and direction, while Charles generally assumed a supporting role. As in the case of the two teams, both would be halved in 1912 when one of the two brothers would succumb to non-aviation related deaths, although here the parallel was juxtaposed: Wilbur, the older of the two, died of typhoid fever, while Charles, the younger of the two, perished in an automobile accident. Nevertheless, Gabriel and Charles were slated to rank among Europe’s leading early-aviation pioneers.

Their first aircraft, broadly based upon the Wright’s gliders with a forward elevator and equal-span wings and powered by a 20-hp Buchet engine, was essentially a steerable box-kite built for Henry Kapferer in March of 1907, but failed to fly. The second, commissioned by Leon Delagrange-a sculptor and Voisin’s contemporary at the Ecole des Beaux-Arts-constituted their first full-standard canard, pusher biplane which incorporated characteristics of several then-notable aviators, including Octave Chanute (biplane wings), the Wright Brothers (the forward elevator), and Lawrence Hargrave (its box-kite tail).

Featuring an ash-framed, steel-jointed, square fuselage which served as the common attachment point for its forward elevating plane, its pilot’s seat, its wings, its engine, and its tail, it sported dual, rectangular-shaped, superimposed wings which spanned 37.8 feet and their cotton and rubber fabric coverings, designated “continental cotton,” were stretched over its ash ribs. They had a 6.56-foot depth, a 5.75-to-1 aspect ratio, and a 496 total square foot area.

Like those of its glider predecessor, they were rugged and strong, but devoid of either the wing-warping or aileron method of lateral control; instead, they contained four vertical planes or partitions, installed at fixed intervals, which subdivided them into individual cells. Although Voisin had intended to provide the necessary lateral stability with them and Berget had highly praised this vertical keel configuration, banking was relegated to wide, sluggish, rudder deflection-induced turns.

A single, 41-square-foot elevating plane protruded ahead of the fuselage frame in a canard arrangement, while a box-kite tail, subdivided into two cells, was attached behind it, a feature which would become characteristic of Voisin’s designs until 1910.

Invented in 1893 by Australian Lawrence Hargrave, the structure, subdivided into sidewall-formed cells, featured the tandem-wing concept introduced by Alberto Santos-Dumont with his 14-bis biplane and employed by Samuel Pierpont Langley. Although it resulted in a particularly strong structure, Hargrave himself discontinued his own box-kite hang glider experiments when he experienced a series of hard landings. The construction method, used by European aircraft, ranked, along with ailerons, tractor (as opposed to pusher) biplane configurations, and pitch control relocation from the front to the rear of the aircraft, as one of the four primary design improvements of early-to mid-1900.

A 25-square-foot turning rudder, attached to the center of the aft cells, provided vertical-axis control.

Power was provided by a 50-hp, Leon Levavasseur-designed Antoinette engine installed on the rear of the central frame behind the main biplane, operating in pusher configuration and driving a twin-bladed, 7.6-foot-diameter metal propeller set at a 4.6-foot pitch.

Resting at a nose-high angle on the ground, the aircraft was supported by two large, pneumatic-tired wheels with spring shock absorbers, while two additional, although smaller, units served as tailwheels. Another, attached below the forward elevating plane, provided protection during nose-over landings.

The open cockpit, comprised of a single wicker seat mounted between the main wings’ leading edges and the powerplant, sported a circular steering wheel whose forward and aft travel deflected the forward elevating plane by means of pushrods and whose left and right rotations activated the direction rudder through wire connections.

The 1,250-pound Voisin Biplane, first flying in 1907, lifted 23 pounds-per-horsepower and 2.37 pounds-per-square-foot of wing surface, attaining 35-mph speeds.

Progressively familiarizing himself with the type, which had been alternatively designated the “Voisin-Delagrange,” Delagrange had been able to cover 500 meters by the fall of 1907.

Crashing during its second of two flights at Issy-les-Molineaux in November, it was rebuilt as the Voisin-Delagrange II, using as many original, salvageable parts as possible, while the succeeding, more maneuverable “III” featured curtains on its two inner main interplane struts.

Slightly larger and heavier, the next Voisin Biplane, designated “Voisin-Farman,” was constructed for Henry (Franch Henri) Farman, whose father was a Paris-based English correspondent. Speaking both French and English, Henry had been active in bicycle and automobile racing, but after sustaining injuries in the 1905 James Gordon Bennett Automobile Race, he shifted interest to aviation, first attempting to take to the air in a Chanute-Herring glider before ordering a powered biplane from the Voisin Brothers factory.

Receiving permission to practice on the Issy-les-Moulineaux military parade ground located on the left bank of the Seine River in the shadows of the Societe Astra and Clement-Bayard dirigible hangars, he quickly improved, conducting acceleration rolls on the flat, unobstructed, dusty field, which often turned muddy during rainy conditions. Following his lead, other budding aeronauts also found its surface conducive to aerial experimentation, soon establishing more permanent presences there with wooden sheds until the area, like College Park in Maryland, developed into Europe’s first practical “airport.” Countless spectators watched an ever-increasing amount of flying activity, which later assumed more structured, air race form.

In order to stimulate aeronautical advancement in France, the Aero-Club had established a series of progressively more difficult challengers as far back as 1904 in return for increasing monetary rewards. A silver trophy, for example, was offered for the 25-meter Coupe Ernest Archdeacon, while a silver medal and 100 francs were awarded to the first ten pilots who could fly 60 meters. The distance and monetary compensation next increased to, respectively, 100 meters and 1,500 francs, and the Grand Prix d’Aviation Deutsch-Archdeacon, requiring a one-kilometer circular pattern, carried a 50,000-franc remuneration.

Transferring his ability from ground-based racing to aerial flying, expressed by his Voisin-Farman I biplane, Farman achieved exponential success. On September 30, 1907, for instance, he completed a 30-meter flight. This increased to 285 meters on October 15, and 11 days later, he covered 2,540 feet in a record 52.6 seconds in his modified Voisin-Farman I-bis, which introduced wing dihedral and a monoplane elevating surface. Unofficially completing a 3,380-foot circuit on November 9, in one minute, 14 seconds, he exceeded the Wright Brothers’ December 17, 1903 duration by 15 seconds, the first European attempt to do so. And on January 13 of the following year, he won the coveted 50,000-franc Grand Prix d’Aviation Deutsch-Archdeacon prize at Issy-les-Moulineaux when he flew the one-kilometer circular course in one minute, 28 seconds. Since the lateral control-devoid aircraft had to make very wide turns with the aid of its rudder alone, however, it actually covered a distance closer to 1.6 kilometers. It was then Europe’s longest sector.

Continually modifying his aircraft, he recovered its surface with rubberized linen, reduced its tailplane span, and replaced its original Antoinette engine with a 50-hp Renault, although it was quickly restored after a single demonstration, creating the first practical European design in the process.

He continued to rack up distance records: on March 20, he flew 4,500 meters in three minutes, 29 seconds; on June 23 he covered more than 14 kilometers in 18 minutes, 30 seconds in Milan; and on July 6, he won the 10,000-franc Armengoud Prize for the first flight to remain aloft for more than 15 minutes, flying 20.4 kilometers in 20 minutes, 20 seconds in Ghent, Belgium.

One admirer commented, “What George Stephenson did for the locomotive, Farman has done for the aeroplane.”

Subjected to continued modification, the basic Voisin Biplane design, which sold in significant numbers, ultimately appeared with both 50- and 60-hp Antoinette, E.N.V., Gnome, Itala, Renault, and Vivinus engines, devoid of its forward elevating plane, and with ailerons, remedying its most significant deficiency.

The Old Rhinebeck Aerodrome example, an original constructed by Norvin C. Rinek of Easton, Pennsylvania, in 1909, incorporated several non-standard features, including a chrome-moly welded steel tube frame, which replaced the original wooden one, and a V-8 engine of his own design.

Disassembled and stored in the rafters of his cord and rope company after only half a dozen fights, it was discovered by Cole Palen some 62 years later. He restored it in his Florida home in 1973, displaying it at the aerodrome until it was loaned to two other prestigious museums in 1979: the National Air and Space Museum in Washington and the Intrepid Sea-Air-Space Museum in New York. Returning “home,” it now remains on display in the New Museum Building up on the hill across from the Pioneer, World War I, and Lindbergh hangars.

The classic profile of the canard, pusher, box-kite Voisin Biplane, despite its early lateral control limitations and slow, wide aerial turning maneuvers, nevertheless became one of the most significant practical pioneer aircraft between 1907 and 1910.

The Deperdussin Racer Aircraft

Posted by: admin  /  Category: Aviation Airplanes

Although technically classified, like the Bleriot XI, the Hanriot Monoplane, and the Curtiss Model D, as a “pioneer aircraft,” the Deperdussin Racer, in physical appearance alone, indicates that it does not belong to this category. Its completely covered, streamlined, bracing wire-devoid fuselage; single, razor-sharp wings; tiny tail surfaces, drag-reducing spinner; faired landing gear; and modern control wheel all reflect advanced technology and speed, placing the type in a “transition” category of its own, between the original, pioneer and later, World War I designations.

It owes its origin to Armand Deperdussin, who was neither an airplane inventor nor a pilot. Beginning his career as a cabaret singer in Belgium, he pursued several professions, none of which were remotely related to aeronautics, including luring customers into motion picture theaters operated by the Lumiere Brothers as a barker and selling fabric at wholesale prices to French department stores. In the fall of 1909, he agreed to supply the Bon Marche store of Paris with a Christmas display featuring an aircraft, but, despite his own interest in the budding science, he knew nothing of aerodynamics or design himself, thus forced to approach the Societe de Construction d’Appareils Aeriens to fill his needs.

Instrumental to this display, and Deperdussin’s future, had been 32-year-old Louis Bechereau, graduate of the Ecole des Arts et Metiers d’Angers and chief engineer there. His reputation had reached “brilliance” stature.

Attracted by its canard aircraft, Deperdussin himself acquired the Societe de Construction d’Appareil Aeriens, located in Bethany, near Rheims, France, in 1910, and renamed it the “Societe de Production des Apppareils Deperdussin,” or “SPAD.”

The intended static display, appearing at the end of the previous year, resembled an Antoinette monoplane with a tailskid.

The flying version, based upon it and retaining the overall Antoinette configuration, particularly in the tailplane, was completed in 1910 and offered in several versions, which varied both by powerplant and number of seats.

The Deperdussin A, for example, had been powered by a three-cylinder Anzani, a 50-hp Clerget, and a 50-hp Gnome engine.

Featuring a long, slender, 24-foot, 11.5-inch spruce and ash frame and a 28-foot, 10.5-inch wingspan covered with oiled cotton, the Deperdussin B, the first version to receive significant attention, succeeded the initial variant in 1911. Powered by a 50-hp, seven-cylinder Gnome engine and weighing 551 pounds, it sported hinged elevator and rudder surfaces, the latter serving as the deflecting surface for vertical control and attached to the remainder of the fixed, stabilizing fin. Cables, actuating the aircraft’s wing-warping mechanism, were routed down to a T-shaped lever, itself mounted on the rear cross member of the chassis, and then passed over pulleys on skids before branching out into two wire pairs which connected with an equal number of points on the wing’s spars. Pilot control was achieved by means of a pinned crosspiece-mounted wheel, its direction of turn differentially deflecting each wing spar-that is, while one was pushed down, the other was pulled up, changing their angles-of-incidence and inducing a bank away from the increased one.

Resting on two wheels and a tailskid on the ground, the monoplane attained a maximum, 56-mph speed in the air.

The type notched up several records. Of the seven aircraft entered in the June, 1911, Circuit of Europe race, for instance, the one flown by Rene Vidart won third place, while the type demonstrated considerable performance capability in the Concours Militaire, held later in the year, between October and November, in Rheims. Indeed, two Deperdussin Monoplanes, along with a Nieuport, had been the only designs capable of meeting the French military’s requirements.

The Deperdussin C, following in 1912, had been powered by a 100 hp Gnome engine and accommodated two persons, and the type, noted for its carrying capacity and speed with large payloads, held all of the world’s records for up to five seats and distances of up to 30 miles until the end of 1911. The aircraft enjoyed widespread use in both France and England.

Separated by only two years, the Deperdussin Racer, which was alternatively known as the “Deperdussin Monocoque,” appeared as if it should have been separated by two decades from its Monoplane predecessor.
As demonstrated by early, fixed-wing aeronautics, aircraft frames required three basic components:

1). The frame or fuselage, considered the common attachment point of its flight surfaces.

2). Supporting methods, such as trusses, cross beams, and bracing wires.

3). A covering or surface, then usually of fabric.

Although wood had traditionally been employed to build up airframe structures, it had, particularly by turn-of-the-century methods, been difficult to mold or bend in order to form a single unit integrally incorporating even two of these parameters until Eugene Ruchonnet, a Swiss pilot and engineer, who had previously worked at the Antoinette factory with Rene Hanriot, sublimated his boat construction experience into aeronautical design, covering a basic frame with mahogany and producing a light, but strong, minimal-drag fuselage concept which could carry high stress loads.

Louis Bechereau, the Deperdussin Racer’s designer, further developed this concept, forming two halves of a fuselage by diagonally overlaying three thin strips of steamed, glued tulipwood, which was ordinarily used in cabinet building, in three cross-crossed layers, permitting them to dry before removing them from the reusable mold and assembling their two halves. The result, designated “monocoque”–from the Greek “mono,” or “single,” and the French “coque,” or “shell,”–resulted in a radical departure from the wooden, trussed fuselages of aircraft such as the Bleriot XI, providing a circular, although decreasing-diameter, cross-section which tapered as it progressed from the nose to the tail, but which carried its own loads, integrally incorporating the three components of frame, support, and covering. Streamlined, strong, and aerodynamic, it obviated the need for external struts or bracing wires and became the standard of aeronautical design up to the present day.

The Deperdussin Racer, with a 20-foot, 1/8th-inch overall length, introduced this advanced construction technology, which represented a “step-change” in aeronautical design.

Equally deviating from the majority of both pioneer and World War I aircraft, it sported single, or mono, high-mounted, razor-sharp wings, which incorporated inverse taper on their inboard trailing edges, spanning 21 feet, 9 ¾ inches and covering 104 square feet of area.

Like its Deperdussin Monoplane predecessor, it featured both hinged elevators and rudders affixed to seemingly tiny, horizontal and vertical stabilizers, covered in proofed linen. The aircraft had a seven-foot, 6.5-inch overall height.

Powered by several successively higher-horsepower Gnome engines, the Deperdussin Racer employed rotary technology.

Engines, evolving from the steam to the internal combustion types, developed progressively more horsepower per pound of engine weight, and the latter, appearing at the dawn of heavier-than-air flight, can be subdivided into reciprocating and rotary categories. Designed by Laurent Seguin and his half-brother, Louis, (whose great-grandfather, Marc, had coincidentally been the nephew of the Montgolfier Brothers who themselves had made the world’s first successful balloon flight in France in 1783) it had its origins in 1907 when they explored a new, light-weight configuration, designated the “Gnome,” which evolved from the previous year’s 34-hp static unit.

Built of solid, drop-forged blocks of steel, the powerplant featured a 13.5-pound crankshaft reduced from its original, 100-pound mass of raw material, and extremely thin piston walls.

Contrasted with the reciprocating engine, whose pistons turned the crankshaft on which the propeller itself was mounted, the rotary type featured a fixed crankshaft about which the cylinder block rotated. Nevertheless, it employed the standard, four-stroke, Otto cycle, although its valves were located in the pistons, and each cylinder, as with both types, experienced a different phase during this cycle.

During the intake stroke, for example, a vacuum formed in the cylinder, forcing the intake valve to open in order to draw the fuel-air mixture in from the crankcase, while it was compressed during the compression stroke, at the end of which its spark plugs fired, slightly before the top dead center position was reached. During the power stroke, the exhaust valves opened before the bottom dead center position, and this was followed by the exhaust stroke.

Featuring symmetrically mounted cylinders round a drum-shaped crankcase, the Gnome rotary engine revolved with optimum balance. The cylinders themselves were designed with head-located inlet and exhaust valves operated by rocker arms, fuel drawn in and burnt gasses expelled by means of centrifugal force, which itself was neutralized by counter-weighted valves. Fuel, entering at one end of this crankshaft, ultimately flowed into the carburetor attached to the other. Blipping the engine during descent cleared the cylinders of any accumulated raw fuel and oil.

A virtual design solution to the often-contradictory balance of power, weight, and reliability, the rotary engine offered several advantages.

1). Because its large, rotating block of cylinders effectively served as a flywheel and there were no engine mounting point-related reciprocating parts, it delivered power very smoothly.

2). The shorter crankcase and crankshaft reduced structure weight.

3). Because the entire block rotated, obviating the need for radiators, water pumps, fans, and cooling liquids, it featured its own integral, airflow cooling method, further reducing structure weight compared to that of water-cooled powerplants.

The rotary engine equally offered three disadvantages.

1). Since it had to be run at full throttle throughout all of its fight phases, it consumed a large amount of fuel.

2). The rotating block, of considerable mass, created a formidable gyroscopic effect, which augmented immediate, rapid right banks, but resisted those to the left. These were slow and sluggish.

3). Because centrifugal force expelled castor oil after a single flow through the engine, as contrasted with the recirculating method employed by the reciprocating type, the aircraft’s range was, to a degree, limited by its oil capacity.

The 50 hp, seven-cylinder Gnome rotary engine, competing with the Antoinette and first appearing at the 1908 Paris Salon, featured a 172-pound structure weight, a 110-mm bore, a 120-mm stroke, and turned at 1,100 revolutions-per-minute.

A later version, offering improved maintenance access and turning at 1,300 revolutions-per-minute, generated 70 hp and followed in 1911, burning almost 90 pounds per hour of fuel as opposed to the 50-hp’s 44.1, and it had a.5-to-1 gallon oil-to-fuel consumption ratio.

The first practical rotary available to aircraft builders, the Gnome, produced in copious quantities totaling 3,638 units between 1908 and 1913, achieved almost all of the world’s speed, altitude, and endurance records for the airframes they powered, such as London-Manchester, Paris-London, trans-Alps, round the Statue of Liberty, and the Circuit de l’Est, becoming the dominant powerplant during the dawn of World War I. Credited with the first significant increase in performance, the rotary engine, like the monocoque fuselage, constituted a step-change in technology.

Powered by a 160-hp, 14-cylinder, two-row Gnome rotary, the Deperdussin Racer, driving a mahogany propeller and fronted by a large, but aerodynamic, drag-reducing spinner which appeared to be the forward, integral portion of the fuselage, achieved maximum, 127-mph airspeeds and feisty maneuverability. It was often dubbed “the flying engine.”

The 992-pound aircraft was ground-supported by a twin-wheel undercarriage with a central skid.

The Racer, like its Monoplane predecessor, retained the latter’s standard cockpit control wheel, whose left or right turn activated the wing-warping mechanism to control its lateral axis, wires stretching from its forward and aft spars routed to two, upper-frame, triangular-shaped king posts above and the lower landing gear assembly below. Pulling or pushing it deflected the elevators for pitch, or longitudinal, axis control, while a foot-operated rudder bar provided yaw control. A wheel rim-located blip switch interrupted engine power to induce descents.

Demonstrating and validating its superior performance characteristics, it notched up an impressive array of accomplishments.

On September 9, 1912, for instance-a swelteringly hot day-Jules Vedrines flew his Deperdussin Racer in a continuous circuit at low altitude during the fourth Gordon Bennett Race, winning the prize for the fastest aircraft, clocked at 105.5 mph, while Marcel Prevost, circling at 20 to 30 feet above the ground in his own aircraft of the same type that afternoon, placed a close second. They were the first to exceed the 100-mph mark. All the other entrants, with the exception of an engine-overheating Hanriot, had withdrawn from the competition the previous evening. The Hanriot itself only completed half the course.

On April 10 of the following year, a pontoon-equipped Deperdussin, again flown by Prevost, won the Schneider trophy at Monaco, the only time in the two-decade history, from 1912 to 1931, of the event that the French had succeeded in doing so.

During the fifth Gordon Bennett Race, held at Bethany Aerodrome, near Rheims, on September 29, 1913, four aircraft had competed, inclusive of two Gnome-powered Deperdussin Racers, one powered by a Le Rhone engine, and an Alfred Ponnier-designed monoplane, itself a development of the Hanriot Racer. Following Henri Crombez’s 10:00 a.m. circuit, Prevost took off in his Gnome-powered, clipped-wing Deperdussin at 11:15 a.m., completing his second, third, fourth, and fifth laps in two minutes, 50 seconds each and covering the 20, ten-kilometer lap course in 59 minutes, 45 3/5 seconds at an average 204 kph, the first to ever do so in under an hour, and achieved an absolute world speed record of 126.67 mph.

The following month, on October 27, a Deperdussin flown by Eugene Gilbert won the Henry Deutsch de la Meurthe air race round Paris.

The Deperdussin Racer became the fastest, most maneuverable, pre-World War I design.

The Old Rhinebeck Aerodrome example, the result of a 1974 trip to Paris during which Cole Palen and his wife, Rita, studied, measured, sketched, and photographed the aircraft on static display in the Musee de l’Air et de l”Espace, was built in his Florida home during that winter, at which time Cole completed two monocoque fuselage frames before destroying the mold he had created prior to them.

A later restoration, undertaken by Brad Adams, Ryan Cassens, Bob Mackenzie, John Nenadic, Paul Savastano, and Nick Ulfik, between 2000 and 2001, was prompted by engine cowl cracks, flat tires, rusty cable rails, peeling spinner and fuel tank paint, and the absence of its 160-hp Gnome powerplant.

After transfer from the hill-located Pioneer Building to the Fokker hangar on the field, the aircraft was fitted with a static engine assembled from spare parts and three wooden valves coated with epoxy glass resin and painted, while its other deficiencies were equally addressed.

In restored guise, it first appeared in the Westchester County Civic Center during the Westchester Radio Aero Modelers Show in February of 2001.

Because of the Deperdussin Racer’s high speeds and minimal surface areas, Cole had decided to limit it to ground taxiing on the grass field which would have failed to offer sufficient length for safe, public-proximity operation, and today, it is often displayed in the courtyard immediately beyond the covered bridge entrance to the aerodrome, a sleek, aerodynamic, high-performance monoplane radically differing from its other pioneer counterparts embodying advanced, step-change technology. It proudly showcases those features which comprise it.
