Embodiment Construction

[0017] The present invention as Figure 1-3 As shown, it includes a hollow shaft 1, a rudder ring 2, an electromagnetic relay 7, an armature 5 and a friction plate 6, and one end of the hollow shaft 1 is connected with a body or an aircraft, and the other end is passed through the rudder ring 2, so Described rudder ring 2 is hollow cylindrical, and the outer wall of rudder ring 2 is fixedly connected with a pair of canards one with an antisymmetric angle of attack and a pair of canards two with a symmetrical angle of attack; like this, due to a pair of canards One has an antisymmetric angle of attack, so an aerodynamically induced rotational moment will be generated when flying against the wind; because the pair of canards two has a symmetrical angle of attack, it can generate a normal control force to change the flight trajectory of the projectile when flying against the wind;

[0018] The rudder ring 2 is rotatably sleeved on the end of the hollow shaft 1, the armature 5 is ...

Abstract

The invention provides a ballistic correction device based on relay control and relates to the field of ballistic correction devices based on relay control. The ballistic correction device provided by the invention can be used for the ballistic correction process of a high-rotation stable aircraft or ammunition. According to the ballistic correction device, the positioning and the ballistic measurement are achieved according to a satellite terminal in the exterior ballistic process; through a control unit, flight errors are calculated and instructions are sent out; and consequently, the rudder surface control can be conducted and the ballistic correction force can be provided in the ammunition flight process, the problem about the normal control force required when a high-rotation ammunition body flies can be solved with a relatively low cost, the guidance capacity of traditional ammunition can be achieved, and the ammunition striking precision can be improved. The ballistic correction device comprises a hollow shaft, a rudder loop, an electromagnetic relay, an armature and a friction sheet. The ballistic correction device has the beneficial effects that the structure is more compact; the driving operation is easier and more convenient; the rudder load is effectively reduced; the correction ammunition posture adjustment is facilitated; the correction efficiency is improved; and the ammunition striking precision is higher.

Description

technical field [0001] The patent of the present invention relates to a ballistic correction device based on relay control, and belongs to the technical field of control devices for aircraft or correction bombs. Background technique [0002] After the traditional ammunition is fired out of the chamber, due to the lack of the ability to actively control the trajectory of the ammunition itself, in addition to being disturbed by the weather, it cannot independently control the trajectory of the ammunition during the course of the ballistic trajectory. Therefore, the traditional ammunition has poor accuracy, large dispersion, and The cost-effectiveness ratio is high, and it needs to consume a huge amount of ammunition for blanket fire coverage to destroy the target. This not only poses a challenge to the logistical supply of ammunition, but also greatly reduces the maneuverability on the battlefield, increases operational risks, and adversely affects combat missions.
