The Curtiss YA-10 Shrike was a 1930s United States test and development version of the A-8 Shrike ground-attack aircraft using various radial engines in place of the inline Vee.
The Curtiss T-32 Condor II was a 1930s American biplane airliner and bomber aircraft built by the Curtiss Aeroplane and Motor Company. It was used by the United States Army Air Corps as an executive transport.
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 Model 55 Kingbird was an airliner built in small numbers in the United States in the early 1930s. It was a twin-engine aircraft with a fuselage derived from the single-engine Curtiss Thrush. The Kingbird had two engine nacelles mounted on the struts on either side of the fuselage that braced the wing and the outrigger undercarriage. A distinctive design feature was the aircraft's blunt nose, located behind the propeller arcs. This allowed the engines to be mounted closer to each other and to the aircraft's centerline, therefore minimising asymmetrical thrust in case of an engine failure. For the same reason, the Thrush's single tailfin was replaced by twin tails on the Kingbird, and the main production model, the D-2 fitted a second horizontal stabilizer and elevator between these fins.
The Curtiss YP-20 was an American biplane fighter project developed by Curtiss for the United States Army Air Service.
The International F-17 Sportsman was a 1920s American three-seat open-cockpit biplane designed and manufactured by the International Aircraft Corporation in Long Beach, California and Cincinnati, Ohio. 107 aircraft were built, 77 of them at Cincinnati.
The Keystone K-47 Pathfinder was an airliner developed in the United States in the late 1920s, built only in prototype form.
The American Eagle A-129 was an American biplane first flown in 1929.
The Monocoupe 110 Special was a United States sporting and racing aircraft of the 1930s and 1940s.
The Curtiss Model 57 Teal was an American monoplane amphibian designed and built by the Curtiss Aeroplane and Motor Company. Two versions were built, a three-seater and four-seater but only one of each was built.
The Swallow Airplane Swallow is an American-built general purpose biplane of the mid- to late 1920s.
The Curtiss O-40 Raven was an American observation aircraft of the 1930s which was built and used in small numbers. A single example of the YO-40, a single-engined Sesquiplane with a retractable undercarriage was built, followed by four examples of a modified monoplane version, the O-40B, which remained in use until 1939.
The Douglas Cloudster II was an American prototype five-seat light aircraft of the late 1940s. It was of unusual layout, with two buried piston engines driving a single pusher propeller. Only a single example was built, which flew only twice, as it proved too expensive to be commercially viable.
The Curtiss CA-1 was an American five-seat biplane amphibian designed by Frank Courtney and built by Curtiss-Wright at St Louis, Missouri.
The Curtiss/Curtiss-Robertson Model 56 Thrush was a 1929 six passenger high-wing fixed undercarriage single-engine cabin monoplane airliner and utility transport powered by either a Curtiss Challenger or a Wright Whirlwind radial engine and built as an enlargement of the earlier Curtiss Robin. Several were used for record breaking endurance flights by female pilots during the early 1930s including one in which the aircraft stayed aloft for almost ten days.
The Curtiss Model 36 XNBS-4 was a 1920s prototype biplane night bomber built by the Curtiss Aeroplane and Motor Company for the United States Army Air Corps.
G Elias & Brother was and American manufacturer of cabinets and aircraft based in Buffalo, New York in the 1920s. A.G. Elias sat on the Manufacturers Aircraft Association's board of directors along with President Frank H. Russell, VP Glenn L. Martin, Charles L. Laurence, Chance M. Vought, S.S. Bradley, George P. Tidmarsh, and Donald Douglas. E.J Elias promoted the construction of a Buffalo municipal airport to aid the local fledgling airplane industry of five aviation companies constructing airplanes and airplane parts. From 1920 to 1925, Elias company's chief engineer, David Earle Dunlap (1896-1957), designed the Elias EM-2 Expeditionary planes. He designed the NBS-3 bomber fuselage and the Elias M-1 Mail plane. Dunlap's Elias TA-1 design was the first United States Army Air Corps Trainer to have a radial engine. After tests a McCook Field, the Army Air Corps selected other manufacturers over the Elias bomber and trainer. The company designed the Elias EM-1 to meet requirements for a multirole amphibian marine expeditionary aircraft. Elias delivered six production Elias EM-2 aircraft with Liberty engines to the United States Navy in 1922.
The L-W-F Model H Owl was a large American twin-boom trimotor biplane designed and built by LWF Engineering as a mail plane in 1920, but after being rejected for that role, the single prototype was sold to the United States Army Air Service for evaluation as a bomber but failed to secure any orders.
The Thunderbird W-14 was a small, three seat American passenger transport, first flown in 1926, entering production, significantly improved, in 1927 with several different engine options. About 40-50 were built before the financial collapse of the company in 1929.
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.
