Yakovlev Yak-45 was the designation for a series of design studies in 1973-1974 for a single-seat fighter. It lost to the Mikoyan MiG-29. [1]
In the early 1970s the Soviet VVS expressed a desire to replace the MiG-21 with a more modern twin-engine fighter with greater air-superiority capabilities. Yakovlev's entry was a series of designs submitted under the designation Yak-45. [1]
The Yak-45 would have been powered by two Favorski Type 69 non-vectoring turbofan engines with afterburners. Derived from the R-28, they were rated at 8,000 kg (17,635 lb) thrust each. The engines would have been positioned ahead of a large delta wing, with an additional large canard foreplane, giving the aircraft an appearance similar to the Saab Viggen. [1]
The design was rejected in favor of the MiG-29. [1]
In 1978-1979 Yakovlev attempted to restart development of the Yak-45 by designing a V/STOL version with two vectoring-thrust nozzles and two RD-38 jets. This aircraft was not developed because the problem of roll associated with the loss of one engine during VTOL operation was never solved. [1]
The Saab 37 Viggen is a retired Swedish single-seat, single-engine, short-medium range combat aircraft. Development work on the type was initiated at Saab in 1952 and, following the selection of a radical delta wing configuration, the resulting aircraft performed its first flight on 8 February 1967 and entered service in 21 June 1971. It was the first canard design produced in quantity. The Viggen was also the most advanced fighter jet in Europe, albeit slower than the earlier MiG-21bis, until the introduction of the Panavia Tornado into operational service in 1981.
The Mikoyan-Gurevich MiG-9 was the first turbojet fighter developed by Mikoyan-Gurevich in the years immediately after World War II. It used reverse-engineered German BMW 003 engines. Categorized as a first-generation jet fighter, it was moderately successful, but suffered from persistent problems with engine flameouts when firing its guns at high altitudes due to gun gas ingestion. A number of different armament configurations were tested, but nothing solved the problem. Several different engines were evaluated, but none were flown as the prototype of the Mikoyan-Gurevich MiG-15 promised superior performance.
The Yakovlev Yak-141, also known as the Yak-41, is a Soviet supersonic vertical takeoff/landing (VTOL) fighter aircraft designed by Yakovlev. It was used for testing.
The Yakovlev Yak-23 was an early Soviet jet fighter with a straight wing. It was developed from the Yak-17 in the late 1940s and used a reverse-engineered copy of a British engine. It was not built in large numbers as it was inferior in performance to the swept-wing Mikoyan-Gurevich MiG-15. Many Yak-23s were exported to the Warsaw Pact nations and remained in service for most of the 1950s, although some were still in use a decade later.
The Yakovlev Yak-1 was a Soviet fighter aircraft of World War II. The Yak-1 was a single-seat monoplane with a composite structure and wooden wings; production began in early 1940.
The Yakovlev Yak-15 was a first-generation Soviet turbojet fighter developed by the Yakovlev design bureau (OKB) immediately after World War II. The main fuselage was that of Yakovlev Yak-3 piston-engine fighter modified to mount a reverse-engineered German Junkers Jumo 004 engine. The Yak-15 and the Swedish Saab 21R were the only two jets to be successfully converted from piston-power to enter production. 280 aircraft were built in 1947. Although nominally a fighter, it was mainly used to qualify piston-engine-experienced pilots to fly jets.
The Yakovlev Yak-17 was an early Soviet jet fighter. It was developed from the Yak-15, the primary difference being tricycle landing gear. The trainer version, known as the Yak-17UTI, was the only Soviet jet trainer of the 1940s. Both aircraft were exported in small numbers and the Yak-17 was soon replaced by the far superior Mikoyan-Gurevich MiG-15 beginning in 1950.
The Mikoyan MiG-AT is a Russian advanced trainer and light attack aircraft that was intended to replace the Aero L-29 and L-39 of the Russian Air Force. Designed by the Mikoyan Design Bureau and built by the Moscow Aircraft Production Association, the MiG-AT made its first flight in March 1996. It is the first joint aircraft development programme between Russia and France and the first military collaborative project between Russia and the West to reach first flight. The design lost out to the Yakovlev Yak-130 in 2002 in the competition for a government contract, and had also been unsuccessfully marketed to countries such as India, Greece, and those of the Commonwealth of Independent States.
The Yakovlev Yak-19 was a prototype Soviet fighter built in late 1940s. It was the first Soviet aircraft to be equipped with an afterburning turbojet, the Klimov RD-10F that was derived from the German Jumo 004 engine. Only two examples were built as it was rejected for service by the Soviet Air Force.
A supersonic aircraft is an aircraft capable of supersonic flight, which is an aircraft able to fly faster than the speed of sound. Supersonic aircraft were developed in the second half of the twentieth century. Supersonic aircraft have been used for research and military purposes, but only two supersonic aircraft, the Tupolev Tu-144 and the Concorde, ever entered service for civil use as airliners. Fighter jets are the most common example of supersonic aircraft.
The Yakovlev Yak-25 was a Soviet military aircraft, an early turbojet-powered fighter aircraft designed by the Yakovlev OKB. The designation was later reused for a different interceptor design. Tasked by the Council of Ministers in a directive issued on 11 March 1947, with producing a straight winged fighter similar to the earlier Yak-19, but powered by a Rolls-Royce Derwent V, OKB-115 swiftly produced the Yak-25, which blazed several trails as the first Soviet fighter with a fully pressurised cockpit, air conditioning, jettisonable canopy, and hydraulic airbrakes on the fuselage amongst other innovations.
The Yakovlev Yak-30 was an experimental Soviet interceptor from the late 1940s. Derived from the Yak-25, from which it differed primarily in having wings sweptback 35° at quarter chord, the Yak-30 retained the fuselage, tail surfaces and undercarriage of the earlier fighter.
The Szolnoki Repülőmúzeum is a large museum displaying old military and civilian aircraft and aircraft engines in Szolnok, Hungary. It was located next to the "Lt. Ittebei Kiss József" Helicopter Base of the Hungarian Air Force; the collection has now moved to premises in the city centre, under the new name of Reptár.
The Yakovlev Yak-30, originally designated Yakovlev 104, was Yakovlev's entry in a competition for the first military jet trainer aircraft designed for Warsaw Pact nations. Designed to succeed the Yak-17UTI, it also led to the development of the Yakovlev Yak-32 sport jet. The Yak-30 lost to the L-29 Delfin, and neither it nor the Yak-32 entered production.
Yakovlev Yak-50 was an early experimental turbojet interceptor aircraft designed in 1948 by the Yakovlev OKB in the USSR. The aircraft was essentially a stretched version of the Yakovlev Yak-30 (1948), with a more powerful engine and greater wing sweep. The Yak-50 is perhaps most significant as the first Yakovlev aircraft equipped with velosipednoye (bicycle) landing gear, a trademark of later Yakovlev designs. The Yak-50 designation was later reused for a propeller-driven aerobatic and trainer aircraft.
The soviet post-PFI projects refer to several Soviet and Russian Air Force projects initiated to replace the PFI-era aircraft.
The Yakovlev Yak-43 was a Soviet VTOL fighter designed as the ground-based version of the ill-fated Yakovlev Yak-141, which failed to reach production. Like the Yak-141, the Yak-43 did not reach production. The Yak-43 would have been the third-generation VTOL/STOL fighter, to follow and eventually replace the Yak-141.
The Yakovlev Yak-1000 was a Soviet supersonic technology demonstrator intended to evaluate the aerodynamic layout and field performance of the cropped delta wing discussed in captured German documents in combination with the new Lyulka AL-5 turbojet. The tandem undercarriage proved to be unsatisfactory and there were serious flight stability problems related to the delta wing, enough so that it never flew after an accident during taxiing tests.
The Sukhoi S-54 was a series of three closely related aircraft proposals; the S-54 trainer aircraft, S-55 light fighter designed for export, and the S-56 carrier-capable light fighter. All members of the family resemble the Sukhoi Su-27 in general form, or the Sukhoi Su-33 more closely, but built around a single Saturn AL-31 engine instead of two, and scaled down accordingly to a smaller layout. The design was offered to several potential customers, including South Africa and India, but was turned down. Development is apparently on hold, awaiting a launch customer.
The Mikoyan-Gurevich I-320 was a prototype Soviet long-range all-weather interceptor aircraft of the late 1940s-early 1950s. Only two were made, with no production following.
