Description

Controllable movable rudder wing lift angle device for PGK seeker

Technical Field

Background

The PGK (precision Guidance kit) precision Guidance component is a ballistic correction module integrating fuze, ballistic detection device, air control surface and control circuit into a whole. The size, the installation method and the weight of the fuse are different from those of the traditional fuse, and the fuse can be directly reloaded to the fuse position of the traditional standard ammunition, so that the shooting precision of the uncontrolled ammunition can be greatly improved. At present, PGK becomes a hot spot of dispute research of military and major countries in the world, and China also develops the research and development work of various types of two-dimensional trajectory correction bullets adopting a PGK form.

The projectile that uses PGK to achieve two-dimensional trajectory modification is also known as a double spin projectile. The projectile rotates forwards, the rotary wing cylinder rotates backwards relative to the projectile, and a bearing is arranged between the rotary wing cylinder and the projectile for isolation. When the rotating speed of the rotary wing cylinder is consistent with the rotating speed of the projectile in the positive rotation direction, the fixed wing air control surface can keep static in an inertial space, so that stable normal force is generated, and trajectory correction is realized. But has disadvantages in practical application. The disadvantages are that: when the PGK is applied to a low spin projectile, the PGK itself is driven by the motor and the gear train decelerates, causing the rotor barrel to spin backwards. However, the chamber is shot out after the uncontrolled missile and the PGK seeker are arranged, and because the lift angle of the air control surface is certain (4 degrees or 5 degrees) at the initial speed and the lift is constant, the projectile body can be driven to deviate from the trajectory for a period of time and distance, and the precision of the PGK is reduced.
