History
Introduction date1911; 113 years ago (1911)

The 1911 Curtiss Model D (or frequently "Curtiss Pusher") is an early United States pusher aircraft with the engine and propeller behind the pilot's seat. It was among the first aircraft in the world to be built in any quantity, during an era of trial-and-error development and equally important parallel technical development in internal combustion engine technologies.

It was also the aircraft type which made the first takeoff from the deck of a ship (flown by Eugene B. Ely off the deck of USS Birmingham on November 14, 1910, near Hampton Roads, Virginia) and made the first landing aboard a ship (USS Pennsylvania) on January 18, 1911, near San Francisco, California.

It was originally fitted with a foreplane for pitch control, but this was dispensed with when it was accidentally discovered to be unnecessary. The new version without the foreplane was known as the Headless Pusher.[1]

Like all Curtiss designs, the aircraft used ailerons, which first existed on a Curtiss-designed airframe as quadruple "wing-tip" ailerons on the 1908 June Bug to control rolling in flight, thus avoiding use of the Wright brothers' patented wing warping technology.

Development

The Model D was a biplane fitted with a wheeled tricycle undercarriage. The construction was primarily of spruce, with ash used in parts of the engine bearers and undercarriage beams, with doped linen stretched over it. The outrigger beams were made of bamboo.[2] Prevented by patents from using the Wright Brothers' wing warping technique to provide lateral control, and with neither the Wrights nor himself likely to have known about its prior patenting in 1868 England, Curtiss did not use the June Bug's "wing-tip" aileron configuration, but instead used between-the-wing-panels "inter-plane" ailerons, instead, as directly derived from his earlier Curtiss No. 1 and Curtiss No. 2 pushers. In the end, this proved to be a superior solution. Both the interplane and trailing-edge ailerons on these early aircraft did not use a hand or foot-operated mechanism to operate them, but very much like the earlier Santos-Dumont 14-bis had adopted in November 1906, required the pilot to "lean-into" the turn to operate the ailerons — on the Curtiss pushers, a transverse-rocking, metal framework "shoulder cradle", hinged longitudinally on either side of the pilot's seat - initially as straight metal tubes resting against the pilot's upper arms; and later achieved with "armrests" in a similar location; achieved the connection between the pilot and aileron control cabling.[3] Almost all Model Ds were constructed with a pusher configuration, with the propeller behind the pilot. Because of this configuration, they were often referred to as the "Curtiss Pusher". Early examples were built in a canard configuration, with elevators mounted on struts at the front of the aircraft in addition to a horizontal stabilizer at the rear. Later, the elevators were incorporated into the tail unit, and the canard surface arrangement dispensed with, resulting in what became called the Curtiss "Headless" Pushers.

In addition to amateur aviators, a Model D was purchased in April 1911 by the Aeronautical Division of the U.S. Army Signal Corps as a trainer (S.C. No. 2), and by the Navy as an airborne observation platform. A number of them were exported to foreign militaries, as well, including the Russian Navy. On November 14, 1910, Eugene Ely took off from USS Birmingham in a Model D. This was the first time an aircraft had taken off from a ship.[4] On January 18, 1911, Ely landed a Model D aboard USS Pennsylvania. This was the first aircraft to land on a ship.

Upon his election in November 1915, Congressman Orrin Dubbs Bleakley became the first government official to fly from his home state to Washington, D.C. The trip was made in a 75 hp (56 kW) Curtiss biplane from Philadelphia, piloted by Sergeant William C. Ocker, on leave from the United States Aviation Corps at the time. The trip took 3 hours, 15 minutes, including an unscheduled stop in a wheat field in Maryland.[5]

A number of Curtiss Pusher original and reproduction aircraft exist, and reproductions of the design date as far back to the era when the original aircraft was in production, mostly built by private parties.

The Aerodrome's Curtiss Pusher was built in 1976 and is powered by an original 1911, 80 HP Hall-Scott engine (since replaced with a restored Curtiss OX-5 engine) obtained from the Smithsonian Institution. It utilizes the original Curtiss control system. The shoulder yoke controls the ailerons as the pilot leans from side to side.
