The Bristol Jupiter was a British nine-cylinder single-row piston radial engine 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 F.2 Fighter was a British two-seat biplane fighter and reconnaissance aircraft of the First World War developed by Frank Barnwell at the Bristol Aeroplane Company. It is often simply called the Bristol Fighter, other popular names include the "Brisfit" or "Biff".
The Bristol Type 143 was a British twin-engine monoplane aircraft designed by Frank Barnwell of the Bristol Aeroplane Company.
The Bristol Scout was a single-seat rotary-engined biplane originally designed as a racing aircraft. Like similar fast, light aircraft of the period it was used by the RNAS and the RFC as a "scout", or fast reconnaissance type. It was one of the first single-seaters to be used as a fighter aircraft, although it was not possible to fit it with an effective forward-firing armament until the first British-designed gun synchronizers became available later in 1916, by which time the Scout was obsolescent. Single-seat fighters continued to be called "scouts" in British usage into the early 1920s.
The Sunbeam Arab was a British First World War era aero engine.
The Bristol Ten-seater and Bristol Brandon were British single-engine biplane transport aircraft built by the Bristol Aeroplane Company in the early 1920s. Only three were built, two of which were used as civil transports and one of which served with the Royal Air Force.
The Bristol Bloodhound was a British two-seat reconnaissance/fighter aircraft designed and built by the Bristol Aeroplane Company as a possible replacement for the Bristol F.2 Fighter for the Royal Air Force. It was unsuccessful, only four prototypes being built.
The Avro 530 was a British two-seat fighter biplane designed in 1916 to compete with the Bristol F.2A. The plane itself was designed in 1916, but not flown until July 1917. It was of fabric-covered wooden construction, powered by a 200 hp (150 kW) Hispano-Suiza engine.
The Bristol Type 107 Bullpup was a British fighter aircraft built in the 1920s. It was not selected for squadron service and only the single prototype was built
The Bristol Type 32 Bullet was a British biplane racing aircraft. It was designed in 1919 by Frank Barnwell as a high-speed testbed for the Jupiter engine being developed in Bristol by Roy Fedden for the Cosmos Engineering company, and also to publicise the company's name by participating in air races.
The Cosmos Mercury was a fourteen-cylinder twin-row air-cooled radial aeroengine. Designed by Roy Fedden of Cosmos Engineering, it was built in the United Kingdom in 1917. It produced 347 horsepower (259 kW). It did not enter production; a large order was cancelled due to the Armistice.
The Bristol Badger was designed to meet a British need for a two-seat fighter-reconnaissance aeroplane at the end of World War I. Despite the 1918 Armistice, three Badgers were delivered to the Air Board to develop air-cooled radial engines, particularly that which became the Bristol Jupiter; two other Badgers were also built.
The Bristol Type 92, sometimes known as the Laboratory biplane, was an aircraft built by the Bristol Aeroplane Company to address the differences between wind tunnel cowling models and full scale cowling for radial engines and was designed as a scaled-up version of a wind tunnel model aircraft. One was built and flew in the mid-1920s.
The Bristol Type 118 was a general-purpose military aircraft, a two-seat biplane built by the Bristol Aeroplane Company in the early 1930s, powered by a Bristol Mercury radial engine and aimed at overseas markets. The Type 120 was a Bristol Pegasus-engined variant entered into an Air Ministry competition and later used for armament tests. Two aircraft were built.
The Vickers E.S.1 was an early British Fighter aircraft of the First World War. A single-seat biplane, only three E.S.1s were built, although at least one was used by a home defence squadron of the Royal Flying Corps.
The Vickers F.B.16 was a British single-seat fighter aircraft of the First World War. It was originally designed to be powered by an experimental radial engine, development of which was abandoned. When re-engined with more powerful and reliable water-cooled V-8 engines, the F.B.16 demonstrated good performance, but only a few prototypes were built, the type not entering service.
The Vickers F.B.24 was a British two-seat fighter aircraft of the First World War. Only a few prototypes were built, as, although it had good performance, the Bristol F.2 Fighter was preferred.
The Vickers F.B.25 was a British two-seat night fighter prototype of World War I designed to attack enemy airships. Completed in 1917, it failed in its official flight tests that year and no order for production resulted.
The Romano R.90 was a prototype single-seat French floatplane fighter of the 1930s. A single example of the R.90 was built, but the type did form the basis of the Romano R.83 and Romano R.92 fighters which were built in secret for the Spanish Republicans during the Spanish Civil War.
The Letov Š-7 was a single-seat, single-engine biplane fighter aircraft designed and built in Czechoslovakia in the early 1920s. It was designed for a single-seat fighter competition but did not reach production.
