Folding aerodynamic rudder of a rocket

Abstract

The invention relates to rocket technology, in particular to a folding aerodynamic rudder for a rocket. The folding aerodynamic rudder includes a rotating part and a body part, a cylindrical torsion and a locking mechanism consisting of compression springs and retainers. The body part of the folding aerodynamic rudder consists of a pylon and a rotation axis. Two pairs of parallel holes are made in the rotating part and the pylon of the body part. The fixed axis of rotation of the rotating part of the folding aerodynamic rudder is installed in the upper hole and is fixed to the pylon with a screw. A cylindrical torsion bar is fixed to the fixed axis with its six-pointed end, the other end of the torsion bar is pre-twisted in accordance with the direction of folding of the aerodynamic rudder and is fixed to the rotating part by means of a pulley. The lower hole made on the rotating part is made so that the locking mechanism of the rotating part can be triggered. The locking mechanism of the rotating part is placed in the hole made in the pylon of the body part and includes the locking latches, the locking supports, the compression springs, the hook, which consists of a cylindrical shaft, a cylindrical nut with a cut thread, and a groove fitted with glue. The part of the retainer that enters the pylon and the hole in the pylon are conical. The technical result is to ensure reliable locking of the folding aerodynamic rudder of the rocket.
