FIELD: reduction of vortices behind aircraft. ^ SUBSTANCE: aircraft has starboard and port wings for forming lifting force; wings are provided with landing flaps for forming considerable lifting force. Vortex generator for forming controllable disturbance vortex is made in form of additional flap whose base is located in area of 10-% semispan to the right and to the left from external end of landing flap and beginning at 60% of depth of lifting wing profile. During flight, additional flap is kept in extended position; it may be retracted in wing when not in use. Controllable vortex is formed with this device. ^ EFFECT: reduction of vortices behind aircraft at landing approach. ^ 15 cl, 9 dwg |
