Yak 52 – Amazing Show!

The Yakovlev Yak 52 is a cool little plane that intrigues me. I saw it do it stuff at Oshkosh 2011 in a great performance. This Soviet trainer which first flew in 1976 is still being produced in Romania by Aerostar. It was designed originally as an aerobatic trainer for students in the Soviet DOSAAF which interestingly trained both civilian sport and military pilots. This fact I found in my reading it think is kinda cool. “The Yak-52, like most Soviet military aircraft, was designed to operate in rugged environments with minimal maintenance. One of its key features, unusual in western aircraft, is its extensive pneumatic system. Engine starting, landing gear, flaps, and wheel brakes are all pneumatically actuated. Spherical storage bottles for air, replenished by an engine driven compressor, are situated behind the rear cockpit and contents displayed on the instrument panels. The operating pressure is between 10 and 50 bars (145 and 725 psi) and an emergency circuit is reserved for lowering the undercarriage if the normal supply is exhausted or the compressor fails” Great little aircraft that seems to be pretty popular here in the states.
