摘要

FIELD: engines and pumps. ^ SUBSTANCE: flat nozzle of jet turbine engine includes two fixed side walls attached to the housing and upper and lower movable flaps installed between them and equipped with control hydrocylinders. Rod of hydrocylinder consists of two hinged links the opposite ends of which are hinged to the housing and the flap respectively. Link of the rod, which is connected to the flap, is arranged at an angle =10-45 to the side wall. Side wall is equipped with a bracket. Rollers installed with possibility of being turned about its axis and contacting with the bracket are provided on the rod. ^ EFFECT: invention allows preventing the deformation of nozzle side walls throughout its surface and increasing the operating life of wall and nozzle as a whole. ^ 2 dwg
