FIELD: aviation; creating lift force and horizontal thrust. SUBSTANCE: wing 1 includes axisymmetric plate with sharp edges and two rounded-off projections located symmetrically relative to center of plate; each projection is twisted relative to its axis of symmetry. Plate may be made with four rounded-off projections located symmetrically relative to center of plate. Wing 1 performs translational motion and oscillations relative to air at creating lift force and horizontal thrust. EFFECT: enhanced aerodynamic efficiency. 3 cl, 8 dwg
