The Bristol Jupiter is a British nine-cylinder single-row piston radial engine that was built by the Bristol Aeroplane Company. Originally designed late in World War I and known as the Cosmos Jupiter, a lengthy series of upgrades and developments turned it into one of the finest engines of its era.
The Bloch MB.130 and its derivatives were a series of French monoplane reconnaissance-bombers developed during the 1930s. They saw some limited action at the beginning of World War II but were obsolete by that time and suffered badly against the Luftwaffe. After the fall of France, a few were pressed into Luftwaffe service.
The Gotha Go 242 was a transport glider used by the Luftwaffe during World War II. It was an upgrade over the DFS 230 in both cargo/troop capacity and flight characteristics. It saw limited combat action. There were multiple glider variants, and it became the basis for a transport aircraft, the: Gotha Go 244.
The Bloch MB.210 and MB.211 were the successors of the French Bloch MB.200 bomber developed by Société des Avions Marcel Bloch in the 1930s and differed primarily in being low wing monoplanes rather than high wing monoplanes.
The PZL.48 Lampart (leopard) was a Polish heavy fighter-bomber design, that remained only a project, owing to the outbreak of World War II.
The Gnome-Rhône 14M was a small 14-cylinder two-row air-cooled radial engine that was used on several French and German aircraft of World War II. While having the same appearance, number of pistons (14) and two-row layout typical of Gnome-Rhône radial engines, the 14M was built to a smaller frame intended to power a lighter class of aircraft. It was designed with lower displacement and power, smaller in size and with less weight compared to the larger, heavier Gnome-Rhône 14N and its well-known predecessor.
The Gnome-Rhône 14N was a 14-cylinder two-row air-cooled radial engine designed and manufactured by Gnome-Rhône just before the start of World War II. A development of the Gnome-Rhône 14K, the 14N was used on several French and even one German aircraft.
The Bloch MB.220 was a French twin-engine passenger transport airplane built by Société des Avions Marcel Bloch during the 1930s.
The Tumansky M-88 was an air-cooled radial engine for aircraft developed in the Soviet Union shortly before World War II.
The Latécoère 611 was a French four-engined maritime reconnaissance flying boat of the Second World War. Although only a single prototype was completed, this served throughout the war, being used by both the Vichy French and Free French navies.
The Potez 62 was a French twin-engine civil airliner, designed by Henry Potez in 1934. The French military adapted this airframe two-years later to create the Potez 650.
The Bréguet 730 was a French flying boat of the 1930s. Built to meet the requirements of the French Navy, it was ordered into production but no aircraft were delivered before France surrendered to Germany in June 1940. Four remaining incomplete airframes were completed after the end of World War II, serving with the French Navy until 1954.
The Bratu-220 was a Franco-Romanian prototype three-engined airliner of the 1930s, built in France.
The Lioré et Olivier LeO 25 was a bomber aircraft produced in France in the late 1920s.
The Tupolev ANT-35 was a 1930s Soviet twin-engined light transport monoplane that entered service with Aeroflot in 1937 as the Tupolev PS-35.
The Blériot 111 was a French four-seat executive transport monoplane designed by André Herbemont. The first French aircraft to be fitted with a retractable landing gear, after six years development it was not ordered into production.
RWD 22 was a Polish twin-engine torpedo bomber and naval reconnaissance floatplane design. Developed by Leszek Dulęba and Andrzej Anczutin of Doświadczalne Warsztaty Lotnicze in 1939, the project was to be developed under the brand of the RWD design bureau. The outbreak of World War II interrupted the design and it never left the planning stage.
The Piaggio P.XIX was an Italian aircraft engine produced by Rinaldo Piaggio S.p.A. during World War II and used to power aircraft of the Regia Aeronautica.
The Gotha Go 241 was a low-wing twin-engined four-seat transport aircraft manufactured by Gothaer Waggonfabrik in the early 1940s and intended for the general aviation market.
