The Wright Model A was an early aircraft produced by the Wright Brothers in the United States beginning in 1906. It was a development of their Flyer III airplane of 1905. The Wrights built about seven Model As in their bicycle shop during the period 1906–1907 in which they did no flying. One of these was shipped to Le Havre in 1907 in order to demonstrate it to the French. The Model A had a 35-horsepower (26 kW) engine and seating for two with a new control arrangement. Otherwise it was identical to the 1905 airplane. The Model A was the first aircraft that they offered for sale, and the first aircraft design to enter serial production anywhere in the world. Apart from the seven machines the Wrights built themselves in 1906–1907, they sold licences for production in Europe with the largest number of Model As actually being produced in Germany by Flugmaschine Wright GmbH, which built about 60 examples.[1]

The 1909 Military Flyer was a one-of-a-kind Model A built by the Wright Brothers. With wings shortened two feet and the same engine salvaged from the 1908 Wright Military Flyer wrecked at Fort Myer, it differed from the standard Wright A in size and had a faster speed. The aircraft was demonstrated at Fort Myer, Virginia beginning June 28, 1909[2] for the Aeronautical Division of the U.S. Army Signal Corps, which offered a contract of $25,000 ($656,204 in 2008 dollars[3]) for an aircraft capable of flying at 40 miles per hour (64 km/h) with two people on board for a distance of 125 miles (201 km). After rigorous trials the Signal Corps accepted the airplane as "Signal Corps (S.C.) No. 1", August 2, 1909,[2] paying the brothers $30,000[4] ($787,444 in 2012 US dollars[3]).

Individual control arrangement

Wilbur and Orville devised slightly different flight controls in the Model A airplanes they flew separately in France and the United States for their 1908 and 1909 public demonstrations. The Smithsonian's National Air and Space Museum refers to "The Wilbur Method" and "The Orville Method". In Wilbur's method, the roll and yaw controls were combined on the same lever at the pilot's right hand. A forward-backward movement controlled the rudder, while a sideways or left-and-right motion controlled wing-warping. In the Orville Method, moving the stick controlled wing-warping, while a knob atop the stick controlled the rudder. In both methods the left-hand lever operated the forward elevator to control pitch. Wilbur trained French and Italian pilots using his method, and Orville trained German pilots while in Germany in 1909 for the Wright GmbH as well as American pilots at the Wright Company flight school using his method.

Survivors

  • Wright Flyer III was itself the prototype in 1908. Flyer III was restored in the late 1940s back into its original 1905 configuration.
  • The original Wright Military Model A plane (Signal Corps No. 1) is now on display at the National Air and Space Museum in Washington, DC.[5] S.C. No. 1 had been significantly modified by the addition of wheels for landing gear and the movement of the elevators, but was restored by the Wright Company to its original configuration before donation to the museum. It is displayed in much the original condition as when the Smithsonian received it in October 1911. The aircraft was displayed in the National History Museum, then protected in Luray, Virginia during WWII, and is now in the Early Flight gallery in the Air and Space Museum.[6]
  • The only original standard Model A to survive, and the sole surviving original Dayton-built example, is the one Orville Wright used to demonstrate at Tempelhof, Germany in September 1909. It resides in the Deutsches Museum, Munich.

Reproductions

  • An exact reproduction of the 1909 Military Flyer is on display in the National Museum of the United States Air Force in Dayton, Ohio. This reproduction was constructed in 1955 by museum personnel. It is equipped with an original engine personally donated for the reproduction by Orville Wright, while the chains, sprockets, and propellers were all donated by the heirs of the Wright estate, and have been added to the replica as they have been received and restored.[7]
  • In 2008 Ken Hyde built an exact replica of the original 1908 Wright Military Flyer which itself was one of the Dayton 7. This was for the 100th anniversary and remembrance of Orville Wright's first trip to Fort Myer and also the death of Thomas Selfridge. Hyde has said in press reports that his reproduction is flyable but for now it will only exist in static display.
