FIELD: missiles.
SUBSTANCE: invention relates to rocket technology and can be used in the development of rocket engines. Rocket engine nozzle on cylindrical elastic hinges comprises a fixed part, a rotary part connected to the fixed part through an intermediate movable housing enclosing the rotary part along its axis, and a sealing elastic hinge with a spherical center in the rotation center of the rotary part, connected with fixed part by sliding tight fit. Rotary part is connected with intermediate movable housing by pair of cylindrical elastic hinges located on opposite sides of intermediate movable housing and having common axle passing through rotation center of rotary part. Elastic hinges consist of two identical diametrically opposed cylindrical sectors, which are not connected to each other and represent packages from alternating thin cylindrical elastic and rigid layers. Cylindrical sectors located in front of rotation axis of rotary part are fixed to last elastic layers with larger radius and are fixed to intermediate movable housing by elastic layers with smaller radius. Cylindrical sectors located behind rotation axis of rotary part are fixed to it by elastic layers with smaller radius and are fixed by elastic layers with larger radius to intermediate movable housing. Intermediate movable housing is fixed to fixed housing of nozzle similar pairs of cylindrical elastic hinges. Cylindrical sectors of these hinges located in front of the axis of rotation of the intermediate movable housing are fixed to it by elastic layers with a large radius and fixed to the fixed nozzle body in elastic layers with smaller radius. Cylindrical sectors located behind the axis of rotation of the intermediate movable housing are fixed to it by elastic layers with a smaller radius and are fixed to the fixed nozzle body in elastic layers with a large radius.
EFFECT: invention reduces angular stiffness of the nozzle suspension assembly.
