LIFTING SURFACE OF SHORT TAKE-OFF AND LANDING AIRCRAFT

摘要

FIELD: aeronautical engineering. SUBSTANCE: lifting surface includes main and tiltable wings provided with slotted flaps. Tiltable wing is located after and below main wing and is connected with it by means of two vertical walls mounted on opposite sides of fuselage. Axle of rotation of tiltable wing is secured in walls. Such construction forms closed loop of lifting surface. Trailing edges of extended flaps of main wing are located leading edge of tiltable wing. EFFECT: increased lifting force due to multi-slotted lifting surface. 4 dwge
