The orbit control power system comprises two or more orbit control engines. The altitude control power system comprises three or more altitude control engines. Upper output shafts of the altitude control engines are connected with inner rings of upper altitude control rolling bearings, the outer rings of the upper altitude control rolling bearings are fixedly connected with upper altitude control engine supports, and orbit control engine supports are fixedly connected with the outer aircraft shell. The rotary control solid attitude and orbit control engine is low in technical difficulty, high in feasibility, simple in structure, high in reliability and flexible in form.

Description

technical field [0001] The invention relates to a rotation-controlled solid attitude and orbit control engine, which belongs to the technical field of rocket attitude and orbit control engines. Background technique [0002] The solid gas attitude and orbit control power system is mainly used in various types of missiles for air defense, anti-missile and space countermeasures. It relies on its own kinetic energy to kill and destroy threatening targets by collision. The overall weight is light and the volume is small. Motorized adjustment capability. [0003] In recent decades, major countries in the world have been carrying out research on new solid attitude and orbit control power systems used in the fields of air defense, anti-missile, anti-satellite and space countermeasures. The current solid propellant attitude and orbit control system can be divided into the following two types: one is the pulse array attitude and orbit control system, the missile is stabilized by spin...

AI Technical Summary

Problems solved by technology

[0004] Each small rocket engine in the above-mentioned pulse array attitude and orbit control system can only be ignited once, and continuous vector adjustment cannot be realized, so the control accuracy is poor; although the gas generator multi-nozzle attitude and orbit control system can realize continuous vector adjustment, However, due to the need to adjust the flow rate, the adjustment of the gas valve is used, which will lead to a series of problems such as thermal protection, ablation, and valve stem impact. It has high requirements for material technology and basic industries, and it is difficult to make technological breakthroughs. It has become a solid power technology development. technical bottleneck
