The Boeing XF6B-1 / XBFB-1 was Boeing's last biplane design for the United States Navy. Only the one prototype, Model 236, was ever built; although first flying in early 1933, it rammed into a crash barrier in 1936 and the design was not pursued further.
The Vought O2U Corsair was a 1920s biplane scout and observation aircraft. Made by Vought Corporation, the O2U was ordered by the United States Navy (USN) in 1927. Powered by a 400 hp (298 kW) Pratt & Whitney R-1340 Wasp engine, it incorporated a steel-tube fuselage structure and a wood wing structure with fabric covering. Many were seaplanes or amphibians.
The Spartan 7W Executive is a cabin monoplane aircraft that was produced by the Spartan Aircraft Company during the late 1930s and early 1940s. The 7W features an all-metal fuselage, as well as a retractable undercarriage. The 7W Executive was popular with affluent buyers worldwide.
The Bellanca CH-400 Skyrocket is a six-seat utility aircraft built in the United States in the 1930s, a continuation of the design lineage that had started with the Bellanca WB-2. Retaining the same basic airframe of the preceding CH-200 and CH-300, the CH-400 was fitted with a more powerful Pratt & Whitney Wasp radial engine.
The Bellanca 31-40 Senior Pacemaker and its derivatives were a family of a six- and eight-seat utility aircraft built in the United States in the late 1930s. They were the final revision of the original late 1920s Wright-Bellanca WB-2 design. The model numbers used by Bellanca in this period reflected the wing area and engine horsepower, each divided by ten. Like their predecessors, these were high-wing braced monoplanes with conventional tailwheel undercarriage.
The Koolhoven F.K.50 was a 1930s Dutch eight-passenger light transport monoplane designed and built by Koolhoven.
The Boeing AT-15 was an American twin-engined bomber crew trainer designed and built by Boeing's Wichita Division. Only two prototypes, designated XAT-15, were built. Plans to build over 1,000 were cancelled on the United States' entry into the Second World War. The proposed name Crewmaker was not officially adopted.
The Bach Air Yacht was a trimotor airliner produced in the United States in the 1920s. Typical of its day, it was a high-wing braced monoplane, with fixed tailwheel undercarriage. Unusual for airliners of the late 1920s, the Air Yachts were constructed almost entirely of wood with steel fittings, undercarriage, and struts. Different models were powered by varying combinations of Wright, Ryan-Siemens, Kinner, Comet, and Pratt & Whitney engines, a large engine in the nose of the aircraft, and two smaller "helpers" under the wings in nacelles supported by struts. As with so many aircraft companies of the late 1920s, the Bach Aircraft Company succumbed to the Great Depression, thus further development of the Air Yacht was abandoned after the 3-CT-9.
The Pratt & Whitney R-2180-E Twin Wasp E was a radial aircraft engine developed in the United States by Pratt & Whitney. It had two rows of seven cylinders each. Its only production application was on the post-World War II Saab 90 Scandia airliner.
The Spartan C4 was an American four-seat cabin monoplane designed and built by the Spartan Aircraft Company.
The Waco E series is a small family of American-built cabin biplanes built between 1939 and 1942, which differed primarily by engine installation.
The Solar MS-1 was an American prototype all-metal sesquiplane airliner built in 1930.
The Spartan C2 is a light aircraft produced in the United States in the early 1930s as a low-cost sport machine that would sell during the Great Depression.
The Spartan 8W Zeus, also designated FBW-1 Zeus was a military aircraft produced in small numbers in the United States in the late 1930s, based on the airframe of the Spartan Executive civil aircraft.
The Sikorsky S-37 was an American twin-engine aircraft built by the Sikorsky Manufacturing Corporation. Both examples of the series were completed in 1927. The S-37 was specifically designed to compete for the Orteig Prize and would be the last land based fixed-wing aircraft Sikorsky would produce.
The Emsco B-2 Challenger was a US three-engined, six passenger aircraft flown in 1929. Only two were built and they were quite soon converted into two different Emsco types, one with one engine and the other with two.
The Ireland Neptune was a four or five place pusher configuration biplane sold in flying boat and amphibian versions. Designed in the U.S. and first flown in 1927, well over 50 were built.
The Zenith Z-6 is a single engine biplane U.S. airliner built in the late 1920s. Its cabin, in the fuselage immediately behind its radial engine, holds five or six passengers depending on engine power. It is flown from an open cockpit further aft. Nine were completed and one has been restored to flight.
The Laird LC-EW was a six seat cabin sesquiplane designed for the industrialist George Horton. It first flew in 1934.
The Vought Corsair Junior or Vought V-100 Corsair Junior was an attempt to produce a cheaper, multi-purpose, export version of the Vought O2U/O3U observation aircraft it had produced for the U.S. Navy. It did not sell and only the prototype was built.
