Developed from Yakovlev UT-3

The Yakovlev Ya-19, (aka S-19 or AIR-19), was a 5-seat light transport aircraft developed directly from the Yakovlev UT-3 during the late 1930s. The Ya-19 did not enter production, despite positive results from flight trials, due to the lack of development of the UT-3 and cancellation of the Voronezh MV-6 engine program, which were the result of changing priorities in the face of the Great Patriotic War.

Design and development

A derivative of the Yakovlev UT-3, the Ya-19was developed as a five-seat light transport by lead designer Oleg K. Antonov.

The Ya-19 mated the wings undercarriage, tail unit and engines of the UT-3 with a new fuselage seating five with a single pilot. Access to the cabin and cockpit was by a door on the port side adjacent to the trailing edge. Four passengers sat in the cabin, two a side and the fifth sat next to the right of the pilot in the cockpit. [1]

In 1940 Aeroflot requested that the Ya-19 should be produced for use on short haul routes, but the increasing pace of rearmament in the Soviet Union meant that only a single prototype was built. Production was curtailed when the UT-3 failed to achieve large scale production. [1]

An ambulance version capable of carrying two stretchers, one walking wounded and a medical assistant was proposed to the VVS. A mock-up review commission approved the design but production relied on continued development of the UT-3 and Ya-19, which was curtailed due to war requirements. [1]

Use of the AIR-19 designation would have been very brief, if used at all, as AIR was dropped as a designation when A.I. Rykov was purged in one of Stalin's pogroms. [1]

Operational history

The sole prototype completed manufacturer's testing in October 1939 and was then passed to the NII GVF (Nauchno-Issledovatel'skiy Institut Grazdahnskovo Vozdooshnovo Flota - civil air fleet scientific test institute), for state acceptance trials which it passed with good results. Fate of the prototype is unknown. [1]

Yakovlev UT-2 military trainer aircraft

The Yakovlev UT-2 was a single-engine tandem two-seat low-wing monoplane that was the standard Soviet trainer during the Great Patriotic War. It was used by the Soviet Air Force from 1937 until replaced by the Yakovlev Yak-18 during the 1950s.

Yakovlev Yak-2

The Yakovlev Yak-2 was a short-range Soviet light bomber/reconnaissance aircraft used during World War II. It was produced in small numbers, and most of them were destroyed during the opening stages of Operation Barbarossa.

Yakovlev Yak-15 fighter aircraft

The Yakovlev Yak-15 was a first-generation Soviet turbojet fighter developed by the Yakovlev design bureau (OKB) immediately after World War II. It used a reverse-engineered German Junkers Jumo 004 engine. Along with the Swedish Saab 21R, it was one of only two jets to be successfully converted from a piston-powered aircraft and 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-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.

Yakovlev Yak-30 (1948) 1948 fighter aircraft prototype by Yakovlev

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.

Yakovlev AIR-7

The Yakovlev AIR-7 was a prototype Soviet high performance light aircraft of the 1930s. It was a two-seat single-engined monoplane, which demonstrated excellent performance during testing. After the prototype almost crashed as a result of flutter, its designer, Alexander Sergeyevich Yakovlev suffered temporary disgrace and no production followed.
