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 Arado Ar 80 was a pre-World War II fighter aircraft, designed by Arado Flugzeugwerke to compete for the Luftwaffe's first major fighter contract. The Ar 80 was uninspiring in terms of performance and also suffered a number of failures. The contest was eventually won by the Messerschmitt Bf 109, and the Ar 80 prototypes ended their days as test aircraft.
The Arado Ar 196 was a shipboard reconnaissance low-wing monoplane aircraft designed and produced by the German aircraft manufacturer Arado. It was the standard observation floatplane of the Kriegsmarine throughout the Second World War, and was the only German seaplane to serve throughout the conflict.
The Arado Ar 68 was a single-seat biplane fighter designed and produced by the German aircraft manufacturer Arado Flugzeugwerke. It was among the first fighters produced when Germany abandoned the restrictions of the Treaty of Versailles and began rearming.
The Arado Ar 240 was a German twin-engine, multi-role heavy fighter aircraft, developed for the Luftwaffe during World War II by Arado Flugzeugwerke. Its first flight was on 10 May 1940, but problems with the design hampered development, and it remained only marginally stable throughout the prototype phase. The project was eventually cancelled, with the existing airframes used for a variety of test purposes.
The PZL P.7 was a Polish gull wing monoplane fighter aircraft designed in the early 1930s at the PZL factory in Warsaw. It was the main fighter of the Polish Air Force between 1933 and 1935. The PZL P.7 was replaced in Polish service by its follow-up design, the PZL P.11c. More than 30 PZL P.7 fighters remained in service during the Invasion of Poland, scoring several kills despite its obsolescence.
The Arado Ar 232 Tausendfüßler, sometimes also called Tatzelwurm, was a cargo aircraft that was designed and produced in small numbers by the German aircraft manufacturer Arado Flugzeugwerke. It was designed during the first half of the Second World War in response to a request by the Reichsluftfahrtministerium for a successor or supplemental transport aircraft to the Luftwaffe's obsolescent Junkers Ju 52/3m. The Ar 232 introduced, or brought together, almost all of the features now considered to be standard in modern cargo transport aircraft designs, including a box-like fuselage slung beneath a high wing; a rear loading ramp, a high-mounted twin tail for easy access to the hold and features for operating from rough fields. It was initially requested to be powered by a pair of BMW 801A/B radial engines, however, an alternative arrangement of four BMW Bramo 323 engines was adopted instead due to a lack of capacity.
The Arado Ar 65 was the single-seat biplane fighter successor to the Ar 64. Both looked very similar. The only major difference was the use of a 12-cylinder inline engine versus the Ar 64's radial. The wingspan was also increased.
The Arado Ar 66 was a single-engined twin-seat training biplane designed and produced by the German aircraft manufacturer Arado. It was the last aircraft to be designed by the aeronautical engineer Walter Rethel in collaboration with Arado.
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.
The Arado Ar 197 was a German World War II-era biplane, designed for naval operations for the never-completed German aircraft carrier Graf Zeppelin. Only a few prototypes were built; the project was abandoned in favour of the Messerschmitt Bf 109T and Me 155.
The Arado Ar 96 is a single-engine, low-wing monoplane of all-metal construction, designed and produced by the German aircraft manufacturer Arado Flugzeugwerke. It was the Luftwaffe's standard advanced trainer throughout the Second World War.
The Breda Ba.64 was an Italian single-engine ground-attack aircraft used by the Regia Aeronautica during the 1930s.
The BMW VI was a water-cooled V-12 aircraft engine built in Germany in the 1920s. It was one of the most important German aero engines in the years leading up to World War II, with thousands built. It was further developed as the BMW VII and BMW IX, although these saw considerably less use. It was also produced in the Soviet Union as the M-17 and Japan as the Kawasaki Ha-9.
The Arado Ar 95 was a single-engine reconnaissance and patrol biplane designed and produced by the German aircraft manufacturer Arado.
The Arado SC II was a biplane trainer designed and produced by the German aircraft manufacturer Arado.
The Arado Ar 79 was an aerobatic two-seat trainer and touring aircraft designed and produced by the German aircraft manufacturer Arado. It was the final civilian aircraft developed by the company.
The Heinkel Doppeldecker 43 was a prototype German fighter aircraft of the 1930s. A single-engined, single-seat biplane, the HD 43 was designed to meet a secret German Reichswehr requirement for a single-seat fighter. It had two-bay wooden wings with a steel-tube fuselage, and was powered by a 750 hp (600 kW) BMW VI engine. The single prototype flew in 1931.
The Arado Ar 81 was a German prototype dive bomber. Because the Reich Air Ministry decided to purchase the competing Junkers Ju 87, only three prototypes of the Ar 81 were completed.
The Arado Ar 69 was a two-seat German beginner's school and sport biplane with an open cockpit, developed in 1933 by Arado Flugzeugwerke.
