FIELD: jet engines. ^ SUBSTANCE: proposed nozzle contains stationary part designed for connection with engine, adjustable flaps and flap orientation means. The latter contain elastic ring whose first circumferential periphery is rigidly connected with end of stationary part, and second circumferential periphery is coupled with adjustable flaps, and control means making it possible to displace second circumferential periphery of elastic ring and containing first jacks. First circumferential periphery of elastic ring is formed by first ring holder used as stationary support for elastic ring and secured on stationary part. Second circumferential periphery of elastic ring is formed by second rigid holder which serves as movable support for elastic ring, being coupled with flaps, and to which free ends of first jacks are connected. Adjustable flaps are installed on end of stationary part and are hinge fastened to panels or tie-rods also secured on second rigid ring holder. ^ EFFECT: provision of adjustable flap of simple design and low cost. ^ 9 cl, 6 dwg |
