Drawing upon its long-standing experience in the design of training aircraft, the Yakovlev OKB embarked on design of a new piston-engined two-seat primary trainer intended to supplant the venerable Yak-52 – Yakovlev Yak-152. The project was revealed in 2002. Development of the machine proceeded in a direct competition with Sukhoi’s Su-49 intended for the same role and possessing a similar configuration and comparable design performance.
The OKB’s concept envisages using the Yakovlev Yak-152 in conjunction with the Yak-130 jet-powered trainer, the two aircraft forming an integrated training system in the primary and advanced trainer roles respectively. The instrument panel arrangement of the Yak-152 is modelled on that of the Yak-130.
The Yakovlev Yak-152 is being designed on the basis of the Yak-54 sports aircraft and embodies design features incorporated into the Yak-54M project. Indeed, models of the Yak-54M and the Yak-152 displayed at Farn-borough International 2000 and MAKS-2003 respectively appear to be nearly identical, featuring only minor differences in the landing gear.
As distinct from the basic Yak-54 (but in common with the Yak-52 and Yak-54M), the Yak-152 will have a tricycle undercarriage. A distinctive common feature of the Yak-54M and Yak-152 projects is the blown cockpit canopy covering the two seats. The front part of the cockpit canopy is moulded in one piece, without the usual visor and its framing, and affords excellent visibility. The aircraft is equipped with the SKS-94M ejection seat system.
The aircraft is of all-metal construction and will be powered by the 360-hp M-14X radial engine driving a three-blade propeller. It will have an AUW of 1.320 kg (2,910 lb), an empty weight of 948 kg (2,090 lb), a wing span of 8.82 m (29 ft), a length of 7.72 m (25 ft 4 in), and a wing area of 13 m2 (140 sq ft). Design performance includes a maximum speed of 500 km/h (311 mph), a flaps-up stalling speed of 110 km/h (68 mph), maximum G-loads of +9/-7, a range of 1,000 km (620 miles) and a take-off/landing run of 175/360 m (575/1,180 ft).
In 2002 the Yak-152 lost to the Su-49 in a tender announced by the Russian Air Force for a primary trainer suited to its needs. However, the future of the Yak-152 seems to have been secured. In May 2004 Commander-in-Chief of the Ukrainian Air Force Lieutenant-General Yaroslav Skal’ko told journalists that there were plans envisaging the use of the Yak-152 for primary training of pilots in the Ukraine.
The aircraft is to be manufactured at production facilities of Odessaviaremservice – an aircraft repair enterprise in Odessa belonging to the Ukrainian Ministry of Defence (which, incidentally, will also assemble the Yak-130 combat trainer). The Ukrainian side, according to Skal’ko, has already reached an agreement with the Yakovlev OKB about setting up its branch in Odessa to supervise this production.
