The Mil V-7 was an experimental four-seat helicopter with AI-7 ramjets at the tips of the two rotor blades. [1] It had an egg-shaped fuselage, skid undercarriage, and a two-bladed tail rotor on a short tubular tail boom. Four aircraft were built in the late 1950s, but only one is known to have flown, with only the pilot aboard. [2]

General characteristics
The Kamov Ka-25 is a naval helicopter, developed for the Soviet Navy in the USSR from 1958.
The Kamov Ka-22 Vintokryl was a rotorcraft developed by Kamov for the Soviet Air Force. The experimental transport aircraft combined the capabilities of a helicopter for vertical take-off and landing with those of a fixed-wing aircraft for cruise. The Ka-22 carried a large payload, having a hold comparable in size to the Antonov An-12. Eight world records for altitude and speed were set by the Ka-22 in its class, none of which have since been broken.
The Antonov An-8 is a Soviet-designed twin-turboprop, high-wing light military transport aircraft.
The Yakovlev Yak-24 is a Soviet twin-engine, tandem rotor, transport helicopter developed by Yakovlev in the 1950s. The Yak-24 saw limited use in the Soviet Air Force, and the exact number produced and duration of service are unknown due to inconsistencies in data.
The Mil V-12, given the project number Izdeliye 65, is a prototype helicopter designed in the Soviet Union and the largest helicopter ever built. The designation "Mi-12" would have been the designation for the production helicopter and did not apply to V-12 prototypes.
The Kamov Ka-15 was a Soviet two-seat utility helicopter with coaxial rotors, which first flew on 14 April 1952 at the hands of test pilot D. K. Yefremov. It was the world's first mass-produced coaxial helicopter. State acceptance trials were completed in 1955, and the helicopter entered production the following year at aircraft factory No. 99 in Ulan-Ude. It was a precursor to the Ka-18 and was fitted with the M-14 engine. It was primarily used for bush patrol, agricultural purposes and fishery control.
The Kamov Ka-10 was a Soviet single-seat observation helicopter that first flew in 1949.
The Hiller YH-32 Hornet was an American ultralight helicopter built by Hiller Aircraft in the early 1950s. It was a small and unique design because it was powered by two Hiller 8RJ2B ramjet engines mounted on the rotor blade tips which weigh 13 lb (5.9 kg) each and deliver an equivalent of 45 hp (34 kW) for a total of 90 hp (67 kW). Versions of the HJ-1 Hornet were built for the United States Army and the United States Navy in the early 1950s.
The Bratukhin Omega was an early Soviet helicopter, the first product of a new Soviet design bureau, OKB-3 that was created from within TsAGI specifically to develop rotary-wing aircraft. Bratukhin's design was a side-by-side twin rotor machine, with each rotor carried on a long outrigger truss. The Omega's rotors were each powered by a separate engine carried in a nacelle also at the end of the truss. Captive trials commenced in August 1941 and revealed severe problems with engine vibration and overheating. Before these could be addressed, however, OKB-3 was evacuated ahead of the German advance into the Soviet Union.
The NHI H-3 Kolibrie was a small helicopter developed in the Netherlands in the 1950s by Nederlandse Helikopter Industrie. It first flew in May 1956.
The Yakovlev EG (Eksperimentalnyi Gelikopter), also commonly known as the Yak-M11FR-1 and Sh (Shootka), was an experimental aircraft with coaxial rotors. The prototype was first flown by V.V. Tezavrovsky in December 1947.
The Kamov Ka-118 is a projected light multirole helicopter with the NOTAR configuration based on the McDonnell Douglas design.
The Kellett XR-8 was a helicopter built in the United States during World War II. It was a two-seat machine intended to demonstrate the feasibility of a twin-rotor system and, while it accomplished this, it also demonstrated a number of problems that prevented further development of this particular design.
The American Helicopter XH-26 Jet Jeep was an experimental tip jet helicopter developed in 1951 by the American Helicopter Company to meet a United States Army and Air Force (USAF) request for a collapsible and air-droppable observation helicopter.
The Tupolev ANT-22 was a large flying boat built in the Soviet Union in 1934. A huge aircraft consisting of two hulls and powered by six engines in three nacelles in a push-pull configuration, it was based on the ANT-11, which was never built. Its enormous weight severely crippled its performance, and it never proceeded beyond the experimental stage.
The Tairov OKO-1, was a passenger transport aircraft produced in the Ukrainian SSR in the USSR in 1937.
The McDonnell XH-20 Little Henry was a 1940s American experimental lightweight helicopter designed and built by McDonnell Aircraft.
The Bratukhin B-5 was a prototype Soviet twin-rotor transport helicopter designed by the Bratukhin aircraft design bureau.
The SNCASE SE-3101 or Sud-Est SE-3101 was an early, experimental French helicopter with twin tail rotors. Only one was built.
The Farrington Twinstar is an American two-seat autogyro that was designed and produced by Farrington Aircraft of Paducah, Kentucky, a company owned by Don Farrington. Now out of production, when it was available the aircraft was supplied as a kit for amateur construction. It first flew in 1993.
