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 Bristol Bulldog is a British Royal Air Force single-seat biplane fighter designed during the 1920s by the Bristol Aeroplane Company. More than 400 Bulldogs were produced for the RAF and overseas customers, and it was one of the most famous aircraft used by the RAF during the inter-war period.
The Aero A.30 was a biplane light bomber and reconnaissance aircraft built in Czechoslovakia in the late 1920s. It originated as an attempt by Aero to improve the performance of the Aero A.11, but soon evolved into quite a different aircraft, larger and more powerful than its predecessor. The aircraft is readily distinguished from other related types by the difference in spans between its wings – the upper set being of much greater span than the lower.
The Aero A.34 Kos was a small sports and touring biplane built in Czechoslovakia in the 1930s.
The Aero A.38 was a Czechoslovakian biplane airliner of the 1920s and 1930s. Following the relatively modern A.35, this aircraft was something of a throwback, marrying a fuselage derived from the A.35 to wings copied from the A.23. A few served with CSA, and others with French airline Compagnie Internationale de Navigation Aérienne. These latter aircraft were powered by a French Gnome-Rhône engine instead.
The Aero A.100 was a biplane light bomber and reconnaissance aircraft built in Czechoslovakia during the 1930s. It was the final step in a design lineage that extended back to the Aero A.11 a decade earlier. A.100s remained in service throughout World War II and for a few years postwar.
The Aero L-60 Brigadýr was a small, high-wing propeller-driven Czechoslovakian STOL utility aircraft developed for both civil and military use. A prototype, designated XL-60, with Argus As 10C engine, first flew on December 24, 1953, but it was not successful. The plane was thoroughly redesigned and the second improved prototype, with M-208B flat-six engine, flew on June 8, 1954. The aircraft's configuration bears a strong resemblance to the Fieseler Fi 156 "Storch" licence-produced in Czechoslovakia during and after World War II, and which this aircraft was intended to replace. By the end of production in 1960, 273 had been built by Aero, including an improved version, the L-160 with an all-metal tail.
The WZ.X was the Polish reconnaissance aircraft designed in the mid-1920s and manufactured in the Centralne Warsztaty Lotnicze (CWL) - Central Aviation Workshops in Warsaw. It was the first combat aircraft of own design built in Poland, in a small series.
The Fokker F.VII, also known as the Fokker Trimotor, was an airliner produced in the 1920s by the Dutch aircraft manufacturer Fokker, Fokker's American subsidiary Atlantic Aircraft Corporation, and several other companies under license. It was an airliner that could carry 6-12 people, depending on the version, and it used a variety of engines; early versions had one engine but three was more common.
The Kawasaki Ki-32 was a Japanese light bomber aircraft of World War II. It was a single-engine, two-seat, mid-wing, cantilever monoplane with a fixed tailwheel undercarriage. An internal bomb bay accommodated a 300 kg (660 lb) offensive load, supplemented by 150 kg (330 lb) of bombs on external racks. During the war, it was known by the Allies by the name Mary. It was, however, mistakenly identified by the British as the Kawasaki Army KB-97 Mary.
The Nakajima A1N, or Navy Type 3 Carrier Fighter, was a Japanese carrier-based fighter of the late-1920s and early-1930s. It was a licensed copy of the British Gloster Gambet fighter, built by the Nakajima Aircraft Company for the Imperial Japanese Navy. Approximately 150 were built in two versions, the A1N1 and A1N2.
Svenska Aero Jaktfalken was a Swedish biplane fighter aircraft, constructed in the late 1920s. The aircraft was first manufactured by Svenska Aero from 1929 to 1932 and later by AB Svenska Järnvägsverkstädernas Aeroplanavdelning (ASJA) from 1934 to 1935.
The Letov Š-18 was a Czechoslovak single-engined, two-seat biplane trainer. It was designed by Alois Smolík at Letov Kbely. The Š-18 first flew in 1925.
Potez 25 was a French twin-seat, single-engine sesquiplane designed during the 1920s. A multi-purpose fighter-bomber, it was designed as a line aircraft and used in a variety of roles, including fighter and escort missions, tactical bombing and reconnaissance missions. In the late 1920s and early 1930s, Potez 25 was the standard multi-purpose aircraft of over 20 air forces, including French and Polish. It was also popular among private operators, notably mail transport companies.
The Gnome-Rhône 14K Mistral Major was a 14-cylinder, two-row, air-cooled radial engine. It was Gnome-Rhône's major aircraft engine prior to World War II, and matured into a highly sought-after design that would see licensed production throughout Europe and Japan. Thousands of Mistral Major engines were produced, used on a wide variety of aircraft.
The Nakajima Army Type 91 Fighter was a Japanese fighter of the 1930s. It was a single-engine, single-seat parasol monoplane with a fixed, tailskid undercarriage.
The Avia BH-33 was a biplane fighter aircraft built in Czechoslovakia in 1927. It was based on the BH-21J which demonstrated promising results by combining the original BH-21 airframe with a licence-built Bristol Jupiter radial engine. Other than the peculiar Avia hallmark of having an upper wing with a shorter span than the lower, it was utterly conventional, even featuring a tail fin for the first time in a Pavel Beneš and Miroslav Hajn design.
The Bartel BM.4 was a Polish biplane primary trainer aircraft used from 1929 to 1939 by the Polish Air Force and Polish civilian aviation, manufactured in the Samolot factory in Poznań. It was the first plane of Polish design put into production.
The Gourdou-Leseurre GL.30 was a racing aircraft built in France in 1920 which formed the basis for a highly successful family of fighter aircraft based on the same design.
The Fizir F1V was the basis from which engineer Rudolf Fizir developed a series of single-engined, two-seat, reconnaissance biplanes fitted with different engines. Construction was carried out in the Yugoslav aircraft factories Zmaj and Rogožarski between 1928 and 1932.
