Yawing force solid fuel gas generator

Abstract

The invention discloses a yawing force solid fuel gas generator. The purpose of controlling the cleanness of fuel gas for a system steering engine is achieved. The fuel gas generator comprises an igniter, a combustion chamber, charge, a fuel gas pipeline, a primary filter net, a secondary filter net, a pressing ring and a plug. The igniter is in threaded connection with the combustion chamber; thecombustion chamber is in threaded connection with the fuel gas pipeline; the charge is fixed to the interior of the combustion chamber through an ignition support and a charge baffle; the primary filter net is subjected to molybdenum wire one-time die pressing into a column type and installed in a fuel gas pipeline inner hole; the secondary filter net is subjected to molybdenum wire one-time diepressing into a column type and installed in a fuel gas pipeline inner hole; the pressing ring is installed in the fuel gas pipeline inner hole; a gas pipeline outlet is provided with a steering engine installing thread, and the plug is in threaded connection with the fuel gas pipeline; fuel gas is clean, and the generator is applicable to a portable missile control system.

Description

technical field [0001] The invention relates to a lateral force solid gas generator, which is mainly applicable to the field of gas generators. technical background [0002] The high-precision and fast-response guidance control technology based on lateral force control is the main direction of aircraft precision guidance research and has a wide range of applications. However, the gas generator used to generate lateral force currently has the following disadvantages: the particle size of the solid phase particles in the gas generated by the combustion of the charge is generally about 0.1 mm, which makes the steering gear easily stuck. In order to solve the jamming problem of the steering gear, technical measures such as a filter screen, a filter plate, and a filter column have been adopted in the existing gas generator. However, due to the high gas flow rate and high impact force, molybdenum or steel single-layer or multi-layer filter screens are easily damaged by gas impact...

Problems solved by technology

However, the gas generator used to generate lateral force currently has the following disadvantages: the particle size of the solid phase particles in the gas generated by the combustion of the charge is generally about 0.1mm, which makes the steering gear easily stuck

However, due to the high gas flow rate and high impact force, molybdenum or steel single-layer or multi-layer filter screens are easily damaged by gas impact and form residues entering the steering gear; steel filter plates and filter columns generally have gas passage pores greater than 0.5mm , the filtering effect is not obvious, and the melting point of the material is lower than the temperature of the gas, so it is easy to be damaged and form residues that enter the steering gear

After the residue enters the steering gear, it is easy to cause wear and sticking of the rudder shaft, reduce the accuracy of lateral force control, and cause aircraft control failure in severe cases
