help Yakovlev Yak-55 FAQ
Why does the Yak-55 have a symmetrical wing?
Its symmetrical airfoil produces similar handling when the aircraft is upright or inverted, which is essential in competition aerobatics. The wing is mounted at mid-fuselage level, helping the single-seat Yak-55 perform rolls and inverted maneuvers predictably.
What engine powers the Yakovlev Yak-55?
The Yak-55 uses the Vedeneyev M14P, a nine-cylinder radial engine producing about 360 horsepower. This is the same basic Soviet engine family used in aerobatic aircraft such as the Yak-50 and Sukhoi Su-26.
Did the Yak-55 actually compete for the Soviet aerobatic team?
Yes. The Soviet team flew the Yak-55 at the 1984 World Aerobatic Championships and won team honors, while the Soviet women's team also finished first.
What changed on the later Yak-55M?
The Yak-55M received a smaller wing to increase its roll rate and better match newer Sukhoi aerobatic designs. It first flew in 1989 and entered production around 1990.
