FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering. Proposed aircraft with propeller crew at its nose comprises fuselage with cabin, wheels, wings wit ailerons, fin and horizontal stabiliser. Screw propeller with flapping blades is arranged at fuselage sides under wings to be driven by crank gear with main and auxiliary crankshafts. Screw blades are articulated by wide ends with main crankshaft cranks. Crankshafts in fuselage are arranged in parallel and parallel with fuselage crosswise axis. Note here that crank gear with one main crankshaft and second stationary auxiliary timing crankshaft rigidly secured to fuselage can be used.
EFFECT: smooth, stable timed rotationally oscillatory motion of blades at various angles of attack.
