FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering, particularly, to helicopter swash plates. Helicopter swash plate consists of two parallel lift guides 1 arranged in one plane and rigidly secured to helicopter frame 2, stationary ring 3, and rotary ring 6. Eccentrics 17 connected by bars 18 with slides 5 are arranged at lower part of said lift guides. Stationary ring 3 is coupled by axles 4 with runners 5 arranged inside lift guide 1. Rotary ring 6 with plate 9 is arranged inside stationary ring 3. Rods 10 are secured to said plate to vary angle of attack of propellers. Levers 15, 15 for transverse and lengthwise control are interconnected by drawbars and walking beams with control stick in helicopter cabin wile pitch-rev-up handle is engaged with eccentrics 17.
EFFECT: increased travel of angle of attack of propellers.
