FIELD: rocket and jet engines. SUBSTANCE: invention relates to engine nozzle units. Proposed nozzle with variable expansion ratio has stationary part and foldable tip formed by set of longitudinal lobes hinge-connected with stationary part, and frame. Frame is connected with lobes by means of links located in radial planes. Hinge joints in butts of lobes with stationary part and links are either spherical or cardan types, and in butt joints of links and frame, are cylindrical, with axis of rotation square to corresponding planes of nozzle. Invention simplifies design of nozzle. EFFECT: improved reliability at reduction of sizes in axial and radial directions. 5 dwg
