Abstract

The invention discloses a device for controlling the posture of a projectile. The device for controlling the posture of the projectile comprises a guide rail; a groove is formed in the guide rail; a sliding strip is embedded in the groove; a thread channel is formed in the length direction of the sliding strip; the sliding strip is connected with a lead screw through the thread channel; a plurality of sawteeth are arranged sequentially on the upper surface of the sliding strip; the sliding strip is engaged with an incomplete gear through the sawteeth; the incomplete gear is connected to a fixing ring through two connecting rods; a rudder shaft is sleeved with the fixing ring; and rudder pieces are connected to the two ends of the rudder shaft correspondingly. Pneumatic control force is generated by changing the deflection angles of the rudder pieces, and the purpose of controlling the posture of the projectile is achieved, and the rudder pieces are simple in structure, convenient to mount and low in cost; and screw transmission and incomplete gear transmission are adopted, the structure is compact, response is rapid, transmission is efficient and accurate, and the constant instantaneous transmission ratio is achieved.

Description

technical field [0001] The invention belongs to the technical field of attitude control devices, and relates to a device for controlling the attitude of an arrow. Background technique [0002] At present, the devices used for the attitude control of projectiles mainly include swing nozzles, side jet engines and gas rudders, etc., which have complex structures and high control costs. For the missiles flying in the atmosphere, the attitude control accuracy is not high, and the flight height is limited. During the flight of the missiles, the shape of the rudder is designed according to the characteristic of the viscosity of the atmosphere. Through the deflection of the rudder, To change the aerodynamic characteristics of the rocket body, to achieve the purpose of controlling the attitude of the rocket body. [0003] Most of the existing devices used for projectile attitude control transmit power through the rod mechanism connected by the rotary hinge. However, due to the gap i...
