Yakovlev Yak-52

The Yakovlev Yak-52 is a Soviet primary trainer aircraft. It first flew in 1976 and is still being produced in Romania, by Aerostar. A descendant of the single-seat competition aerobatic Yakovlev Yak-50, the all-metal Yak-52 is powered by a 360 hp, 9-cylinder radial engine, the Vedeneyev M14P. The aircraft has inverted fuel and oil systems permitting inverted flight for as long as two minutes. The engine drives a two-bladed counter-clockwise rotating, constant-speed, wood and fiberglass laminate propeller. The Yak-52, like most Soviet military aircraft, was designed to operate in rugged environments with minimal maintenance. One of its key features, and a radical departure from most western aircraft, is its extensive pneumatic system. Engine starting, landing gear, flaps, braking and steering are all pneumatically actuated. A number of "westernised" versions of the Yak-52 are now produced. The replacement of the existing Soviet avionics, fitting of a three-blade aerobatic propeller (Yak-52W) and conversion to conventional "tail-dragger" landing gear (Yak-52TW) are the major modifications to the standard aircraft. There is also a factory produced Yak-52TD tail-dragger version which looks like a small Yak-11. On April 16, 2004, a modernized variant Yak-52M was flown in Russia. It is fitted with modernized engine M-14Kh, three-blade propeller, ejector seats and other modifications. It is expected, that some of Russian aircraft will be modified to this standard. #52 #Acrobatic #Aerobatic #Aircraft #Airplane #Competition #Military #Plane #Pneumatic #Russia #Russian #Soviet #System #Trainer #Yak #Yak52 #Yakovlev
