Problems solved by technology

[0003] The torpedo trajectory is a horizontal trajectory, the maximum speed of an ordinary torpedo is no more than 50Kn, and the maximum speed of a supercavitating torpedo can reach 300Kn, but its navigation medium is air; the trajectory of a submarine-launched missile in water is a vertical trajectory, and its trajectory control in water is only Stabilize the attitude of the projectile, and do not perform complex trajectory control such as large-angle turns, so the vertical trajectory control method greater than 100Kn is still blank

Embodiment Construction

[0051] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0052] The invention provides a real-time correction method for high-speed sea mine strikes, the flow of which is as follows figure 1 shown, including the following steps:

[0053]Step 1. According to the expected strike point and the position information of the mine load itself, the attitude angle of the unit velocity vector of the mine load pointing to the strike point is obtained as a program control command, including the pitch angle θ g , heading angle ψ g .

[0054] Establish mine body coordinate system o b x b the y b z b , where o b is the geometric center of the mine, o b x b the y b z b is the space coordinate system established with the geometric center of the mine as the origin, and moves with the movement of the mine. In general, x can be set b is the gravity axis of the mine; establish the navigation coordinate system as o 0 x 0...

Abstract

The invention discloses a real-time correcting method for torpedo high-speed striking, and belongs to the technical field of trajectory control. The real-time correcting method comprises the followingsteps that firstly, according to an expected striking point and position information of a torpedo load, a pitching control instruction, a yaw control instruction and a roll stable control instructionare calculated, then the stable control instructions are clipped, and rudder instruction iterative computing process of a pitching channel, a yaw channel and a roll channel are executed, then rudderangle assignment is carried out on a rudder instruction for each channel so as to achieve the control of a torpedo load steering engine, so that the torpedo load is aimed at the expected striking point for striking. According to the process, in the rudder instruction iterative computing process of each channel, a calculation model considering channel angular rate and one stable control instructionis established, finally rudder angle distribution is carried out on the calculated rudder instruction of each channel to realize steering engine control, and the steering engine control is correctedin real time according to a striking result so that the real-time correction of the torpedo high speed can be realized, and the striking precision is further improved.

Description

technical field [0001] The invention relates to the technical field of ballistic control, in particular to a real-time correction method for high-speed strike of a sea mine. Background technique [0002] At present, torpedoes and submarine-launched missiles are mature underwater high-speed ballistic control technologies, while in the field of sea mines, active attack sea mines are uncontrolled ballistics. [0003] The torpedo trajectory is a horizontal trajectory, the maximum speed of an ordinary torpedo is no more than 50Kn, and the maximum speed of a supercavitating torpedo can reach 300Kn, but its navigation medium is air; the trajectory of a submarine-launched missile in water is a vertical trajectory, and its trajectory control in water is only Stabilize the attitude of the projectile, and do not perform complex trajectory control such as large-angle turns, so the vertical trajectory control method greater than 100Kn is still blank. Contents of the invention [0004]...
