Novel spinning missile control method taking spinning missile spin cycle as control reference

Abstract

The invention provides a novel spinning missile control method taking a spinning missile spin cycle as a control reference. According to the scheme, guide instructions obtained by resolving GPS signals are a pitching equivalent rudder deflection angle and a yaw equivalent rudder deflection angle under a quasi missile body coordinate system, wherein the pitching equivalent rudder deflection angle and the yaw equivalent rudder deflection angle need to be converted into an actual pitching rudder deflection angle and an actual yaw rudder deflection angle under a missile body coordinate system respectively; and when a rudder surface is deflected to a reference position, the actual rudder deflection angles are half of the pi times of the equivalent rudder deflection angles in respective guide instructions, rudder deflection reversing is carried out when the rudder surface is deflected to the reference position, and then a gyroscope preassembling angle is set to realize compensation decoupling on a spinning missile double-channel control system.

Description

technical field [0001] The present invention relates to a novel control method of a rotary bomb, especially a novel rotary bomb control method which takes the spin period of the rotary bomb as the control reference. Background technique [0002] Rotary missiles refer to a type of missile aircraft that continuously rolls around its own longitudinal axis during flight. It has a series of advantages such as simplifying the structure and composition of the control system, improving penetration capabilities, relaxing processing and manufacturing error tolerances, and avoiding asymmetrical ablation. , widely seen in artillery shells, rockets, tactical missiles, strategic missile reentry warheads, etc., represents an important direction in the development of weapons and equipment, such as the XM982 and other guided artillery shells in the United States, and the Tornado rocket in Russia. The reentry warheads of the latest RAM air defense missiles of the United States, Patriot-3 miss...

Problems solved by technology

Even if the control point is determined according to the position of the rudder surface, it will be difficult to realize the control system in engineering because the rudder deflection cannot realize the complete cycle control.
