The Bristol Hercules was a 14-cylinder two-row radial aircraft engine designed by Sir Roy Fedden and produced by the Bristol Engine Company starting in 1939. It was the first of their single sleeve valve designs to see widespread use, powering many aircraft in the mid-World War II timeframe.
A flying boat is a fixed-winged seaplane with a hull, allowing it to land on water, that usually has no type of landing gear to allow operation on land. It differs from a floatplane as it uses a purpose-designed fuselage which can float, granting the aircraft buoyancy. Flying boats may be stabilized by under-wing floats or by wing-like projections from the fuselage. Flying boats were some of the largest aircraft of the first half of the 20th century, exceeded in size only by bombers developed during World War II. Their advantage lay in using water instead of expensive land-based runways, making them the basis for international airlines in the interwar period. They were also commonly used for maritime patrol and air-sea rescue.
The Sopwith Pup was a British single-seater biplane fighter aircraft built by the Sopwith Aviation Company. It entered service with the Royal Flying Corps and the Royal Naval Air Service in the autumn of 1916. With pleasant flying characteristics and good manoeuvrability, the aircraft proved very successful. The Pup was eventually outclassed by newer German fighters, but it was not completely replaced on the Western Front until the end of 1917. Remaining Pups were relegated to Home Defence and training units. The Pup's docile flying characteristics also made it ideal for use in aircraft carrier deck landing and takeoff experiments.
The Hawker Hart was a British two-seater biplane light bomber aircraft of the Royal Air Force (RAF). It was designed during the 1920s by Sydney Camm and manufactured by Hawker Aircraft. The Hart was a prominent British aircraft in the inter-war period, but was obsolete and already side-lined for newer monoplane aircraft designs by the start of the Second World War, playing only minor roles in the conflict before being retired.
The SPAD S.VII was the first of a series of highly successful biplane fighter aircraft produced by Société Pour L'Aviation et ses Dérivés (SPAD) during the First World War. Like its successors, the S.VII was renowned as a sturdy and rugged aircraft with good climbing and diving characteristics. It was also a stable gun platform, although pilots used to the more manoeuvrable Nieuport fighters found it heavy on the controls. It was flown by a number of the famous aces, such as France's Georges Guynemer, Italy's Francesco Baracca and Australia's Alexander Pentland.
The Fairey Aviation Company Fairey III was a family of British reconnaissance biplanes that enjoyed a very long production and service history in both landplane and seaplane variants. First flying on 14 September 1917, examples were still in use during the Second World War.
The Sikorsky Ilya Muromets were a class of Russian pre-World War I large four-engine commercial airliners and military heavy bombers used during World War I by the Russian Empire. The aircraft series was named after Ilya Muromets, a hero from Slavic mythology. The series was based on the Russky Vityaz or Le Grand, the world's first four-engined aircraft, designed by Igor Sikorsky. The Ilya Muromets aircraft as it appeared in 1913 was a revolutionary design, intended for commercial service with its spacious fuselage incorporating a passenger saloon and washroom on board. During World War I, it became the first four-engine bomber to equip a dedicated strategic bombing unit. This heavy bomber was unrivaled in the early stages of the war, as the Central Powers had no aircraft capable enough to rival it until much later.
The Tupolev ANT-7, known by the VVS as the Tupolev R-6, was a reconnaissance aircraft and escort fighter of the Soviet Union. The R-6 traces its roots back to early 1928 when the Soviet Air Force needed a long-range multirole aircraft. The requirements were that it could be used for long-range transport, defensive patrolling, reconnaissance, light bombing and torpedo attack.
Anatra was an aircraft manufacturer founded by Artur Antonovich Anatra at Odessa, Ukraine, then Russian Empire in 1913 which manufactured several light aircraft designs from then to 1917.
The Junkers W 33 was a German single-engine transport aircraft. It was aerodynamically and structurally advanced for its time (1920s), a clean, low-wing all-metal cantilever monoplane. Almost 200 were produced. It is remembered in aviation history for the first east–west non-stop heavier-than-air crossing of the Atlantic.
Tupolev acquired much experience in building his first two aircraft, which he employed for the next one, the ANT-3. By this time, Soviet Air Force leaders were convinced that metal was a highly usable substance in the building of airplanes. Tupolev therefore guided AGOS- TsAGI in creating the first Soviet all-metal aircraft. The ANT-3 was Tupolev's first practical aircraft.
The Chyetverikov MDR-6 was a 1930s Soviet Union reconnaissance flying-boat aircraft, and the only successful aircraft designed by the design bureau led by Igor Chyetverikov.
The Nieuport B.N.1 was a prototype British single-engined fighter aircraft of the First World War. It was a single-engined biplane intended to replace the Sopwith Camel, but only one was built, being destroyed in a crash. The Sopwith Snipe was built instead to replace the Camel.
The Yokosuka Ro-go Ko-gata(YokoSho-shiki Ro-go Ko-gata) was a Japanese reconnaissance floatplane developed during the First World War by the Japanese Navy Arsenal at Yokosuka, and one of the first indigenous Japanese aircraft to enter production. There were 218 of these aircraft built for the Imperial Japanese Navy, which remained in use until 1928.
The Krunichev T-411 Aist is a Russian light utility monoplane designed by the Russian company Aeroprogress and placed into production by the Khrunichev State Research and Production Space Center. A version is marketed in the United States as the Aeroprogress T-411 Wolverine powered by a Continental TSIO-550-B.
The Henry Farman HF.30 was a two-seat military biplane designed in France around 1915, which became a principal aircraft of the Imperial Russian Air Service during the First World War. Although it was widely used on the Eastern Front, and by the factions and governments that emerged in the subsequent Russian Civil War, it is not well known outside that context: the HF.30 was not adopted by other Allied air forces, and the manufacturers reused the "Farman F.30" designation for the Farman F.30 in 1917.
The Short Admiralty Type 81 was a series of British two-seat floatplanes built prior to the First World War, and used by the Royal Naval Air Service in the early years of the war. They were powered by 160 hp (120 kW) Gnome Lambda-Lambda 14 cylinder two-row rotary engines and had folding wings to aid storage on ship, hence the popular name Short Folder, shared with a number of other seaplanes made by Short Brothers.
The Gribovsky G-5 was a small, low powered Russian single seat sports aircraft from the late 1920s.
The Grigorovich MK-1 was a large trimotor floatplane, built and tested in Imperial Russia in 1916.
