Pulse type posture control thruster based on common combustion chamber

Abstract

The invention discloses a pulse type posture control thruster based on a common combustion chamber. An inner hole is formed in the combustion chamber. The chamber wall of the combustion chamber is provided with a U-shaped groove in the radial direction. The combustion chamber is arranged in a shell. The rear end of the combustion chamber is connected with a servo motor through a transmission mechanism, and the combustion chamber is driven by the servo motor to intermittently rotationally move around an axis. A grain bin comprises a bin body, a first elastic element and a push block, the grainbin is arranged above the shell, a preset number of grain components are stored in the bin body, and the grain components are pushed towards the inner hole through the push block under the elastic force action of the first elastic element. An electric ignition mechanism is arranged on the outer wall of the shell, and an electrode of the electric ignition mechanism extends into the shell and can make contact with a reed electrode of each grain component. A spraying pipe is fixedly arranged on a front bearing end cover of the shell. Through the technical scheme of the pulse type posture controlthruster, the structure is compact, the mass is small, the specific impulse is high, the posture control power system ignition and posture control strategy difficulty is lowered, and the work flexibility is improved.

Description

technical field [0001] The invention relates to the technical field of attitude control power systems, in particular to a pulse type attitude control thruster based on a common combustion chamber. Background technique [0002] At present, full solidification, long-term storage, safety and reliability, and maintenance-free are the main development directions of modern advanced weapon systems. Among them, the solid attitude control power system has become the most critical technical difficulty in the process of full solidification. The pulsed solid attitude control power system is a kind of solid attitude control power system. Because of its simple principle and high reliability, it is widely used in the attitude control of weapon systems. Its working principle is: according to the attitude control requirements, sequentially ignite the pulse attitude The charge part in the thruster is controlled to generate high-temperature and high-pressure gas in the combustion chamber, and ...

AI Technical Summary

Problems solved by technology

However, each independently loaded pulse thruster requires an independent thermal protection structure, pressure-bearing structure and ignition system, which are large in number and heavy in weight, which reduces the specific impulse of the attitude control power system; each pulse thruster is installed outside the weapon system At different positions on the circumference, the working output thrust is not fixed relative to the center of mass of the weapon system, which increases the difficulty of ignition and attitude control strategies; the installation positions of a large number of pulse thrusters occupy a large space and the number is limited, and the ability to output pulse thrust is limited. , cannot be dynamically changed in a complex attitude control environment, and the flexibility is poor
