A lateral force solid gas generator

Abstract

The invention discloses a lateral force solid gas generator, which solves the problem of the cleanliness of the gas used for the steering gear of the control system. The gas generator includes: igniter, combustion chamber, charge, gas pipeline, primary filter, secondary filter, pressure ring, plug. The ignition tool and the combustion chamber are connected by thread; the combustion chamber and the gas pipeline are connected by thread; the charge is fixed in the combustion chamber by the ignition bracket and the drug retaining plate; the primary filter is molded into a cylindrical shape with molybdenum wire and installed in the gas pipeline hole; the secondary filter screen is molded into a column shape with molybdenum wire at one time, and installed in the inner hole of the gas pipeline; the pressure ring is installed in the inner hole of the gas pipeline; the outlet of the gas pipeline has a steering gear installation thread, and the plug and the gas pipeline are connected by threads; The gas cleaning provided by the invention is suitable for 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. [0002] technical background [0003] 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 ga...

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
