The Convair R3Y Tradewind was an American 1950s turboprop-powered flying boat designed and built by Convair.
The Heinkel He 116 was an extremely long-range mail plane designed to deliver airmail between Germany and Japan. Several examples were built for this role, as well as a small batch to be used in the long-range reconnaissance role.
The Heinkel He 45 was a light bomber produced in Germany in the early 1930s, one of the first aircraft adopted by the newly formed Luftwaffe. Its appearance was that of a conventional biplane and included seating for pilot and gunner in tandem, open cockpits. Developed in parallel with the He 46, it appeared in 1931 as a general-purpose biplane and was employed mainly as a trainer, but was also used by the Luftwaffe for reconnaissance and light bombing duties. Production of this plane totalled 512 aircraft, including those built under licence by Gotha, Focke-Wulf, and BFW.
The Piaggio P.32 was an Italian medium bomber of the late 1930s, produced by Piaggio, and designed by Giovanni Pegna. It was a modern design for its time, but was a failure due to lack of powerplants commensurate with its high wing loading.
The Heinkel HD 42 50, later designated the Heinkel He 42 was a German two-seat biplane seaplane originally designed for the Deutsche Verkehrsfliegerschule, and later built for the German Luftwaffe. The aircraft was used until the end of World War II as a trainer for maritime pilots.
The Heinkel HD 17 was a military reconnaissance aircraft produced in Germany in the late 1920s.
The Heinkel HD 36 was a trainer developed in Germany in the 1920s at the request of the Swedish Air Force, which was in search of a new trainer aircraft. The newly formed air force had previously evaluated the HD 35, found it to be underpowered, and asked Heinkel to address this problem. Heinkel's response was a development of the HD 35 modified to use the Mercedes D.III engine instead. The HD 36 also dispensed with the third cockpit that had been a feature of the HD 35 and HD 21 before it, but otherwise the design was largely the same. The single example built by Heinkel was tested by the Air Force, and found still not quite satisfactory, was modified by CFM until the problems had been largely eliminated. Once this had happened, CFM built two batches of 10 aircraft, delivering them in 1928 and 1930 as the Sk 6.
The Heinkel HD 25 was a two-seat shipboard biplane reconnaissance floatplane developed in Germany during the 1920s for production in Japan.
The Heinkel HD 39 was a special-purpose cargo aircraft developed in Germany in the 1920s to distribute the Berlin newspaper B.Z.. It was a conventional single-bay biplane with staggered wings of equal span, and a fuselage that nearly filled the interplane gap. The pilot sat in an open cockpit, and the undercarriage was of fixed, tailskid type with divided main units. The sole example of the type was built after Ernst Heinkel found out, by chance, that B.Z. required such an aircraft and had ordered two machines from Albatros. Heinkel convinced publisher Ullstein-Verlag to purchase a third aircraft from his firm.
The Tupolev '102' and Tupolev '101' were 1950s projects for a turboprop airliner and assault transport by the Tupolev Design Bureau. The aircraft designs were almost identical but the '101' had a rear loading ramp and tail barbette for two Nudelman-Rikhter NR-23 cannon. The internal arrangement also differed with the '101' cabin being unpressurised apart from the flightdeck and a small cabin for ten passengers, whilst the '102's pressurised cabin was in one section, configured for 40 passengers.
The InterPlane Skyboy is a two-seat, side-by-side, high wing, single engine, pusher configuration ultralight aircraft that was manufactured as a completed aircraft by InterPlane Aircraft of Zbraslavice, Czech Republic.
The Ago Ao 192 Kurier was a small German twin-engined aircraft designed and built by AGO Flugzeugwerke in the 1930s. A small production run of six aircraft followed three prototypes, these being used as transports.
The Gotha Go 150 was a light aircraft designed at the German company Gothaer Waggonfabrik in the late 1930s. It was intended for civilian use, but ended up being used as a military trainer.
