Missile rudder surface control mechanism

Abstract

The invention discloses a missile rudder surface control mechanism. Much space of a missile body needs to be occupied for installation of rudder motors at present. According to the missile rudder surface control mechanism disclosed by the invention, each rudder room I is fixed to one adjacent rudder room II through a connection room; each rudder room I is connected with a rudder I, and each rudder room II is connected with a rudder II; each rudder I is connected with the corresponding rudder room II through a connection rod I; a rudder shaft I fixed on each rudder I penetrates through a shaft sleeve fixed to one end of the corresponding connection rod I, and forms a revolute pair with a through hole I and a blind hole of the corresponding rudder room I; each shaft sleeve is arranged in a through groove I of the corresponding rudder room I; a slide block fixed to the other end of each connection rod I forms a spherical pair with an annular guide rail, and the annular guide rail is fixed to the bottom of a through groove II of the corresponding rudder room II; a rudder motor I drives the corresponding slide block; and a rudder shaft II of each rudder II forms a revolute pair with a through hole II of the corresponding rudder room II, and a rudder motor II drives the corresponding rudder shaft II. According to the missile rudder surface control mechanism disclosed by the invention, the rudder motor of one special rudder is moved into the rudder room where the rudder motor of another rudder is located, thus occupation for the volume of the missile body is reduced, and the space utilization efficiency is effectively increased.

Description

technical field [0001] The invention belongs to the field of weapon equipment, and in particular relates to a control mechanism for a missile rudder surface. Background technique [0002] The missile rudder rotates around the rudder axis during flight to adjust the missile's position and posture and generate control force and control torque on the missile, so that the missile can adjust its flight trajectory in time to achieve the purpose of precise strike. At present, the rotation of most rudder surfaces is mainly controlled by the steering gear, and the steering gear is installed in the body of the projectile, which occupies a large volume of the projectile body. During design, the size of the projectile body must be increased to ensure the installation space of the steering gear and other related mechanisms. With the continuous development of missile technology, higher requirements are put forward for the external dimensions of missiles, and even special requirements are ...
