Antonov Helicoplane        

Built by the Russian military engineer K. A. Antonov [К. А. Антонов], in development at St. Petersburg from 1907-1911. The essence of the machine was that it rose vertically by the use of the counter-rotating rotors and after gaining enough height it was flown horizontally by the propeller. In 1907 military engineer K.A.Antonov applied for, and in 1912 obtained a patent for his Helicoplane.

The whole system was driven by one 25 hp engine, so a complex system of cogwheels and rods was probably necessary to work the rotors and propeller. As the Helicoplane – according to reports – did not fly, it may be presumed that it was too heavy. As he was a military engineer it can be assumed that there was some form of financial backing or other help received from the Russian government.

The helicoplane was built and tested in St.Petersburg during 1910. Despite all systems working as expected, the Helicoplane failed to takeoff.

Antonov was otherwise prominent in Russian aviation as he participated in the design and building of the 6,900 m³ dirigible “Krechet” in 1910.

Antoinette Monobloc / Blindé / Latham       

The Antoinette Monobloc of 1911 was the last design of the soon liquidated, and then-named firm “Antoinette Aéroplan-Ateliers”. Powered by a 50-60 hp Antoinette engine, the Leon Levavasseur-designed machine, aka the Antoinette Blindé, aka the Antoinette Latham, never left the ground.

One of the first streamlined aircraft, it had a cantilever wing, without any external bracing, a spatted four wheel main undercarriage, and was extensively armoured for protection from ground fire. It was too heavy to fly more than a few yards.

Antoinette III / Ferber Biplane No.IX

Aeroplane of bamboo construction was incremental improvements to the Gastambide-Mengin II, by French Army Capitaine Ferdinand Ferber also known as the Antoinette III, and powered by an Antoinette motor of 50 hp. On September 22, 1909 at Boulogne, while preparing for a cross-channel attempt, Capitaine Ferber, b.1862, was killed on this machine when after a half-hour flight it overturned when it struck a mound during its landing.

It has two identical wings, one on top of the other.

Antoinette I / Antoinette II / Gastambide-Mengin II / Levasseur Gastambide-Mengin

The Antoinette I was very similar to the Antoinette II, but No. II with ailerons and also carried the first passenger.

First flown in February 1908, the Antoinette II was also known as the Gastambide-Mengin II.

Characterized by its tricycle undercarriage and low-mounted rudder, this monoplane was designed and built by Léon Levavasseur and fitted with a 50-hp Antoinette V-8 engine.

The relatively successful machine made at least seven flights and went through several different design iterations.

The Gastambide-Mengin led to the later Antoinette.

Antoinette

Antoinette was a French manufacturer of light gasoline engines. Antoinette also became a builder of aeroplanes, most notably the record-breaking monoplanes flown by Hubert Latham and René Labouchère. Based in Puteaux, the Antoinette concern was in operation between 1903 and 1912. The company operated a flying school at Chalons for which it built one of the earliest flight simulators.

Antoinette Article

Antoinette began as a private venture led by the engineer Léon Levavasseur and financed by Jules Gastambide, who owned an electricity generating station in Algeria. While on holiday with Gastambide and his family in 1902, Levavasseur expressed his interest in the emerging field of aviation and proposed the development of light, powerful engines for use in aircraft. Levavasseur then suggested to Gastambide’s daughter, Antoinette, that the engines should be named after her. Gastambide financed the venture. Levavasseur patented the V8 engine configuration that year. By 1904, most of the prize-winning speedboats in Europe were powered with Antoinette engines. During this time, he designed engines of various configurations of up to thirty-two cylinders.

Antoinette was incorporated in 1906, with Gastambide as president and Levavasseur as technical director. Aviation pioneer Louis Blériot was the vice-president . Antoinette displayed an automobile with a 7.2 L (439 cu in), 32 horsepower (24 kW) V8 engine in the 1906 Paris Salon de l’Automobile of that year.

The company’s primary business was the sale of engines to aircraft builders. Their engines were used in the Santos-Dumont 14-bis of 1906, Paul Cornu’s rudimentary helicopter of 1907, the Voisin biplane that was modified and piloted by Henri Farman who used it to complete Europe’s first 1 kilometer circular flight in January 1908, and other significant pioneer aircraft.

The Farman-Voisin biplane was powered by a water-cooled Antoinette V8 engine which developed 50 horsepower (37 kW) at 1,400 rpm. It used an early form of direct gasoline injection and weighed only 190 pounds in working order, including the water-filled cooling system. The engine block was cast aluminium, holding removable steel cylinders. Levavasseur’s Antoinette engines often included advanced features, including direct fuel injection and evaporative engine cooling.

Levavasseur experimented with the construction of aircraft and in 1906 the Antoinette company was contracted to build an aircraft for Captain Ferdinand Ferber. In 1908 Blériot tried to dissuade the directors of Antoinette from becoming aircraft manufacturers, fearing that they would begin competing against him for customers. Blériot left the company when his advice was ignored.

In early 1909, the Antoinette company worked with the French Army at Camp Châlons near Mourmelon-le-Grand to establish the first military aircraft trials, a flight school and a workshop. The school included the Antoinette Trainer – a rudimentary flight simulator that comprised a half-barrel mounted on a universal joint, with flight controls, pulleys, and stub-wings (poles) to allow the pilot to maintain balance while instructors applied external forces.

One of their earliest pupils was the adventurer Hubert Latham. Within months of learning to fly Latham became the company’s principal instructor. His pupils in 1909 included Marie Marvingt, who became the first woman to fly combat missions as a bomber pilot and established air ambulance services throughout the world, and Infante Alfonso, Duke of Galliera, cousin of King Alfonso XIII of Spain and the first Spanish military pilot.

In the spring of 1909, Latham made several impressive flights. This convinced Levavasseur that Latham could cross the English Channel in an Antoinette aircraft and win the Daily Mail prize for doing so. Latham made two attempts to cross the English Channel in July 1909, both of which were unsuccessful due to engine failure while over the Channel. Between Latham’s attempts, former Antoinette vice-president Blériot successfully crossed the Channel in his own aircraftusing a simpler and more reliable 25 hp (19 kW) air-cooled Anzani W3 engine and a more efficient Chauvière propeller.

Latham’s efforts to promote Antoinette products were more successful at the Grande Semaine d’Aviation de la Champagne on 22–29 August 1909 at Reims, France, where he won the altitude prize, finished second in the speed competition, took third place in the Gordon Bennett Cup for aeroplanes, and, in the Grand Prix event, trying to fly the longest distance around the circuit in a single uninterrupted flight, he won second prize in one aircraft (an Antoinette IV) and fifth prize in another (an Antoinette VII).
At the 1910 Gordon Bennett Trophy race at Belmont Park in the United States, Latham flew an Antoinette VII with a 100 horsepower (75 kW) V16 engine.

Levavasseur left the Antoinette company in November 1909, shortly after Gastambide. Gastambide and Levavasseur returned to the company in March 1910, Gastambide as president of the board and managing director and Lavavasseur as technical director. After Levavasseur’s return, he designed the Antoinette military monoplane, a streamlined monoplane with cantilever wings, which was ultimately rejected by the military. The Antoinette company went bankrupt shortly afterward.
