FIELD: engines and pumps.
SUBSTANCE: aeroplane comprises wing and two coaxial bearing propellers rotating in opposite directions with swash plates. The axis of the shaft of each propeller is installed to facilitate a forward turn in the plane of aeroplane axis of symmetry at an angle, calculated from the vertical position and determined according to a formula, given in description. The center of the axis rotation coincides with the aeroplane gravity center. Diameter of bearing wings corresponds to the load onto the blade-swept area not exceeding 140...150 pounds/square inch. The wing is fabricated pivotal relative to transverse axis of its profile and can be assembled with a required angle of attack or can be feathered.
EFFECT: increase of landing safety at engine failure.
