The Curtiss Falcon was a family of military biplane aircraft built by the American aircraft manufacturer Curtiss Aeroplane and Motor Company during the 1920s. Most saw service as part of the United States Army Air Corps as observation aircraft with the designations O-1 and O-11, or as the attack aircraft designated the A-3 Falcon.
The Curtiss NC is a flying boat built by Curtiss Aeroplane and Motor Company and used by the United States Navy from 1918 through the early 1920s. Ten of these aircraft were built, the most famous of which is the NC-4, the first airplane to make a transatlantic flight. The NC-4 is preserved in the National Museum of Naval Aviation, at NAS Pensacola, Florida.
The Curtiss SC Seahawk was a scout seaplane designed by the Curtiss Aeroplane and Motor Company for the United States Navy during World War II. The existing Curtiss SO3C Seamew and Vought OS2U Kingfisher were gradually replaced by the Seahawk in the late stages of the war and into peacetime.
The Curtiss F6C Hawk is a late 1920s American naval biplane fighter aircraft. It was part of the long line of Curtiss Hawk airplanes built by the Curtiss Aeroplane and Motor Company for the American military.
The Curtiss F7C Seahawk was a carrier-capable biplane fighter aircraft of the United States Navy Marine Corps in the late 1920s and early 1930s.
The Naval Aircraft Factory TS-1 is an early biplane fighter aircraft of the United States Navy, serving from 1922 to 1929.
Friedrichshafen FF.49 was a German, two-seat, single-engine float-plane designed by Flugzeugbau Friedrichshafen in 1917.
The Curtiss CR was a racing aircraft designed for the United States Navy in 1921 by Curtiss. It was a conventional single-seater biplane with a monocoque fuselage and staggered single-bay wings of equal span braced with N-struts. Two essentially similar landplane versions were built as the CR-1 and CR-2, which were both eventually converted to seaplanes as the CR-3 in 1923 and CR-4 in 1924. A refined version was developed for the US Army Air Service under the designation R-6. These latter two aircraft featured refined aerodynamics included surface-mounted radiators.
The Curtiss HS was a single-engined patrol flying boat built for the United States Navy during World War I. Large numbers were built from 1917 to 1919, with the type being used to carry out anti-submarine patrols from bases in France from June 1918. It remained in use with the US Navy until 1928, and was also widely used as a civil passenger and utility aircraft.
The Curtiss Model R was a utility aircraft produced for the United States Army and Navy during World War I. It was a conventional, two-bay biplane with slightly staggered wings of unequal span. The aircraft was provided with two open cockpits in tandem and fixed tailskid undercarriage, but many were built for the Navy with twin floats replacing the wheels. During the course of the war, Model Rs were used for general liaison and communication duties, as well for observation, training, and as air ambulances. In practice, the Curtiss powerplants supplied with these aircraft proved insufficient and were mostly replaced with Liberty engines. The Navy's Model R-3 floatplane had extended-span, three-bay wings, and was intended for use as a torpedo bomber. Some of these were later fitted with wheeled undercarriage and transferred to the Army as bombers under the designation Model R-9.
The Curtiss XP-10 was an American experimental biplane fighter developed by Curtiss and tested by the United States Army Air Corps, but rejected due to disappointing performance and major problems with the cooling system.
The Cranwell CLA.3 was a parasol winged single-engined, single-seat British aircraft built to compete in the Lympne air races of 1925. It was designed and built by an amateur group drawn from staff and pupils at the RAF College Cranwell. Though it won one prize and set a Class record, only one CLA.3 was made.
The Dunne D.8 of 1912 was a tailless swept wing biplane, designed by J. W. Dunne to have inherent stability. One example was supplied to RAE Farnborough. License-built Burgess-Dunne models were used by the US Signal Corps and United States Navy and the short-lived Canadian Aviation Corps. It was the latter's first and only warplane.
The Burnelli RB-1 was a US twin engine biplane airliner prototype from 1920, incorporating a lifting body fuselage.
The Gallaudet D-1 was a prototype American biplane observation aircraft built by the Gallaudet Aircraft Company during World War I for the United States Navy. Completed in mid-1916, its manufacturer's flight testing was delayed by damage suffered during the tests, shortages of qualified pilots and the weather; the D-1 could not conduct its service flight testing until early 1917. The Navy found the aircraft only suitable for limited duties and operated it for several months before returning it to the factory later that year to have its deficiencies remedied. This was done, but the D-1 was never reassembled for unknown reasons and it was scrapped after the war.
The World War I Aeroplanes Fokker D.VII is an American homebuilt aircraft that was designed by Herbert Kelley and produced by World War I Aeroplanes Inc of Poughkeepsie, New York. When it was available the aircraft was supplied in the form of plans for amateur construction. The aircraft is a replica of the First World War Fokker D.VII fighter aircraft.
The Naval Aircraft Factory Giant Boat or GB was a 1919 maritime patrol aircraft project undertaken by the Naval Aircraft Factory (NAF), the in-house aircraft production arm of the United States Navy. The proposed flying boat was larger and heavier and would have possessed a longer range than any similar type then in existence, but the project was hampered by labor and funding shortages stemming from deep post-World War I U.S. military budget cuts, and in 1921, navy leaders prioritized other aircraft types and ended the project. The single incomplete prototype is believed to have been broken up after 1925.
The 1929 Curtiss Model 53 Condor, also known as the Curtiss Model 53 Condor 18 or the Curtiss CO Condor, was a civil passenger version of the Model 52 Condor bomber. A twin-engined biplane, it carried 18 passengers.
The Gallaudet D-2 was a prototype American biplane observation aircraft built by the Gallaudet Aircraft Company during World War I for the United States Army. Based on the earlier Gallaudet D-1, the D-2 had more powerful engines and had other improvements. The first prototype was completed in 1917, but crashed before it was accepted so Gallaudet had to build a replacement at its own expense. Two aircraft were completed in 1918, but further development ceased after the last one crashed with the death of the pilot, the first aviator to be killed in Rhode Island. All aircraft built or in the process of being constructed were subsequently scrapped.
The Duesenberg 16-valve straight-4 aero engine was based on the company's earlier engine of a similar configuration used for automotive racing. Completed in 1916, the first two engines were delivered to the Gallaudet Aircraft Company for use in their D-1 maritime patrol aircraft later that year.
