Aviatsionnaya Ispitatelnaya Stantsiya (AIS) was a naval air test station in Russia during World War I notable for designing and producing several aircraft designs. The facility was founded at the Petrograd Polytechnic Institute near the end of 1916 with a seaplane base on Krestovsky Island.
Two aircraft designs were created by AIS. The first, produced by engineer P. A. Shishkov, was a Farman pusher-biplane type modified to carry a torpedo, powered by a 130 hp Clerget engine. First flight was achieved in August 1917, and several flights of more than 1 hour were completed. A second design, named Aist, was built in the fall of 1917, as a two-seat seaplane powered by a 150 hp Sunbeam engine. The Aist was armed with two machine guns, one fixed and one on a flexible mount.
| Model name | First flight | Number built | Type |
|---|---|---|---|
| AIS torpedo carrier | August 1917 | 1 | Torpedo bomber |
| AIS Aist | 1917 | 1 | Maritime patrol seaplane |
A seaplane is a powered fixed-wing aircraft capable of taking off and landing (alighting) on water. Seaplanes are usually divided into two categories based on their technological characteristics: floatplanes and flying boats; the latter are generally far larger and can carry far more. Seaplanes that can also take off and land on airfields are in a subclass called amphibious aircraft, or amphibians. Seaplanes were sometimes called hydroplanes, but currently this term applies instead to motor-powered watercraft that use the technique of hydrodynamic lift to skim the surface of water when running at speed.
Nieuport, later Nieuport-Delage, was a French aeroplane company that primarily built racing aircraft before World War I and fighter aircraft during World War I and between the wars.
The Hawker Hart is a British two-seater biplane light bomber aircraft that saw service with 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.
A triplane is a fixed-wing aircraft equipped with three vertically stacked wing planes. Tailplanes and canard foreplanes are not normally included in this count, although they occasionally are.
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 was 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. The Ilya Muromets was the world's first multi-engine aircraft in production and at least sixty were built. 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.
The Tupolev TB-1 was a Soviet bomber aircraft, an angular monoplane that served as the backbone of the Soviet bomber force for many years, and was the first large all-metal aircraft built in the Soviet Union.
Grigorovich M-5 was a successful Russian World War I-era two-bay unequal-span biplane flying boat with a single step hull, designed by Grigorovich. It was the first mass production flying boat built in Russia.
The Junkers G 24 was a German three-engine, all-metal low-wing monoplane passenger aircraft manufactured by Junkers from 1925. Junkers F 24 was the designation for single-engine versions of the same aircraft.
Anatra (Анатра) was an aircraft manufacturer founded by Artur Antonovich Anatra at Odesa, Ukraine, then Russian Empire in 1913 which manufactured aircraft until 1917. Artur Anatra had previously helped fund the purchase of the first aircraft to arrive in the Russian Empire, in 1909.
The Junkers W 33 was a German 1920s single-engine low-wing monoplane transport aircraft that followed Junkers standard practice making extensive use of corrugated aluminium alloy over an aluminium alloy tube frame, that was developed from the similar but slightly smaller Junkers F 13, and evolved into the similar W 34. One example, named Bremen, was the first aircraft to complete the much more difficult east–west non-stop heavier-than-air crossing of the Atlantic.
The ANT-3 was a Soviet all-metal aircraft designed by the Tupolev Design Bureau. Tupolev acquired much experience in building his first two aircraft, later using his experience to construct 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 Short Type 320, also known as the Short Admiralty Type 320, was a British two-seat reconnaissance, bombing and torpedo-carrying "folder" seaplane of the First World War.
The Anatra Anadis was developed in 1916 as a single-seat fighter variant of the Anatra Anasal reconnaissance biplane. The main difference between the two aircraft was the streamlined fuselage, the lack of a rear seat in the Anadis, plans for a forward-firing gun and a different engine.
The Yokosuka 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 Grigorovich MK-1 was a large trimotor floatplane, built and tested in Imperial Russia in 1916.
