Description
Technical field
The present invention relates to a kind of lateral force pack boronitridings, are primarily adapted for use in gas generator field.
Technical background
High-precision fast-response Guidance and control technology based on lateral force control is aircraft precise guidance research Main way,
It has a wide range of applications.But presently, there are following disadvantages for the gas generator for generating lateral force: powder charge burning generates gas
Solid phase particles partial size is typically about 0.1mm in body, so that steering engine is easy clamping stagnation.To solve the problems, such as steering engine clamping stagnation, existing combustion gas hair
Raw device uses the technical measures such as filter screen, filter plate, Filter column.But since gas flow rate is high, impact force is big, molybdenum matter or steel
Single-layer or multi-layer filter screen be easy by combustion gas impact failure formed residue enter steering engine；The filter plate of steel, Filter column combustion gas
It is typically greater than 0.5 millimeter by hole, filter effect is unobvious, and material fusing point is lower than fuel gas temperature, is more easily damaged
It forms residue and enters steering engine.Residue be easy to cause rudderpost abrasion, clamping stagnation after entering steering engine, reduces lateral force control precision, seriously
The failure of Shi Zaocheng flying vehicles control.
Summary of the invention
To solve the shortcomings of the prior art and defect, it is solid that the present invention provides a kind of lateral force that can export clean gas
Body fuel gas generator.Columnar filter screen is made using the high molybdenum filament of fusing point, particle in combustion gas was combined using two-stage strainer
Filter, while the parameters such as quality, outer diameter, height for controlling strainer guarantee the density consistency of strainer, guarantee the stabilization of combustion gas output
Property.
Realization process of the invention is as follows:
A kind of lateral force pack boronitriding, comprising: igniter, combustion chamber, powder charge, gas pipeline, primary filter, two
Grade strainer, pressure ring, plug.
The igniter is threadedly coupled with combustion chamber use, and use copper sealing ring (than steel ductility and elasticity is good,
Sealing is more preferable) and zero type sealing rubber ring double-layer sealing structure of rubber；
The combustion chamber, using being threadedly coupled, is sealed with gas pipeline using copper sealing ring；
Primary filter, secondary filter, pressure ring installation space are designed in the gas pipeline entry design venturi, middle position,
Outlet end processes external interface screw thread；
The powder charge free loading propellant in the combustion chamber, is fixed by igniting rack and grate；
The primary filter is wound using diameter of phi 0.25mm molybdenum filament, is molded into column type multi-pore structure (similar steel wire lump
Structure), use maximum bubble method actual measurement pressure at two ends difference for 250Pa~300Pa.Primary filter compares steel material fusing point
Height will not be melted by high-temperature gas.Former molybdenum filter screen is compared, overall structural strength is high, is not easy by high-speed flow erosion damage.
Larger filtering gap, cylindricality strainer outer diameter Φ 7.36mm~Φ 7.42mm, height 5.0mm are formed by structural parameter control strainer
~5.1mm, quality 1.00g~1.05g, are installed in gas pipeline, may filter that greater particle size residue, while not retardation gases
Pass through.
The secondary filter is wound using diameter of phi 0.20mm molybdenum filament, is molded into column type multi-pore structure (ibid), is used
It is 300Pa~350Pa that maximum bubble method, which surveys pressure at two ends difference,.It is high that secondary filter compares steel material fusing point, will not be by
High-temperature gas melts.Former molybdenum filter screen is compared, overall structural strength is high, is not easy by high-speed flow erosion damage.Pass through structure
The smaller filtering gap of state modulator strainer formation, cylindricality strainer outer diameter Φ 7.36mm~Φ 7.42mm, height 5.00mm~
5.10mm, quality 1.15g~1.20g, are installed in gas pipeline, may filter that compared with small particle residue, while not retardation gases
Pass through.
The pressure ring is installed in gas pipeline, carries out compression fixation to strainer.Primary filter after compression is fixed,
Secondary filter combines closely to form combined filter structure, and is fitted close with gas pipeline.Primary filter filters out larger grain
Diameter residue, secondary filter are filtered out compared with small particle residue, final output clean gas, and solid residue partial size is less than 10 μ in combustion gas
m.The plug is installed at gas pipeline outlet screw thread, and then plug does not have to when gas generator is connect with steering engine.
Working principle of the present invention: igniter lights a fire to powder charge after being powered, and powder charge burning generates combustion gas, and gas pipeline is logical
Inlet throat control gas flow is crossed, combustion gas is flowed outward via gas pipeline, and primary filter carries out larger particles in combustion gas
Filtering, secondary filter smaller particle in combustion gas is filtered, combustion gas after filtering twice to flow to steering engine formed lateral force.
The invention has the advantages that the configuration of the present invention is simple, is assembled quick, easy to maintain.Combustion gas is carried out just using primary filter
Begin to filter, effectively reduces the solid phase particles in combustion gas.Fine filtering is carried out to combustion gas using secondary filter, is further reduced combustion gas
In solid phase particles.Primary filter that the present invention uses, secondary filter intensity are high, fusing point is high, stable and reliable in work.
