Description

Steering engine driving control module of accurate guidance component

Technical Field

The utility model provides an accurate guidance subassembly steering wheel drive control module, relates to the steering wheel drive field, especially relates to a steering wheel drive circuit.

Background

The basic concept of the ballistic correction bullet is that under the condition that the structural parameters of the original bullet are kept basically unchanged, a ballistic correction module is additionally or alternatively arranged on the bullet, the space position of the bullet at a certain moment in flight is detected by a GPS or a ground radar, the position is compared with an ideal ballistic preset in a ground fire control computer, and the distance or direction of a correction mechanism on the bullet is corrected according to the deviation.

The two-dimensional trajectory correction fuze can greatly improve the accuracy of conventional ammunition hitting a target at a low cost, wherein the implementation of a PGK (precision Guidance kit) execution device to realize two-dimensional correction of a shot is a research hotspot at present. The PGK executing device changes the current in the stator winding through the variable load circuit to adjust the electromagnetic torque between the stator and the rotor, so that the yaw moment required by correcting the projectile trajectory is controlled, and the aim of correcting the projectile trajectory is fulfilled.

The PGK steering engine mainly has the function of changing the aerodynamic force of the bullet so as to change the posture of the bullet to cause the change of the speed direction and achieve the purpose of correcting the trajectory. Such an actuator is in principle easy to implement, but it occupies as little space as possible to be mounted on the projectile, and its difficulty in miniaturization is a great obstacle, and also very great difficulty in implementing a high-speed spinning projectile.
