FIELD: engines and pumps, transportation. ^ SUBSTANCE: invention relates to aviation, particularly, to the method of producing an aircraft reverse-thrust turbine engine. The proposed method consists in turning the reversing jets in the reversing device by means of flaps and a deflector grill. Here note that the deflector grill blades rear edges are set up at the angle equal to that of the reversing jets turning in the range of ϕ = 90°...135°, while the flaps are arranged so that the deflector grill front edge plane be at the angle of alpha = 20°...60° relative to the flaps plane. ^ EFFECT: higher efficiency thrust reverse, efficient protection of the engine of an ingress of foreign objects from the airfield surface attained by increased efficiency of deflector grill. ^ 4 dwg |
