Description
Technical field
The utility model relates to infrared signature enhancing technology, is specifically related to a kind of infrared signature intensifier.
Background technology
Infrared signature is one of foundation of distinguishing of it and other target as the intrinsic property that target showed.We also can realize obscuring purpose true, decoy by changing the presentation of target infrared feature simultaneously.One of key that forms infrared signature is an energy source, at present, owing to be subjected to the application background condition restriction, often adopts the mode of inner heating to design the infrared signature device to form effective infrared signature.Therefore, mode of heating just becomes one of the key of the formation of infrared signature device.The mode of heating of infrared signature intensifier mainly contains two kinds at present: a kind of is the chemical reaction heating, and used chemical reaction mainly is the reaction of magnesium water; Another is with the Electric heating of battery as heating source.Wherein, the chemical reaction efficiency of heating surface is higher, but it is longer to reach time of chemical reaction equilibrium, and therefore the radiation feature of wayward infrared signature intensifier is simultaneously used and be restricted.Advantages such as control is flexible though Electric heating has, balance weak point Time Created, the efficiency of heating surface is low, and the effective time is short.Facts have proved: the infrared signature device that existing mode of heating forms is subjected to constraints such as quality, volume, can't satisfy the application demand of continuous variation.Therefore, need seek based on brand-new, the design approach of the infrared signature intensifier of mode of heating efficiently.
Summary of the invention
It is a kind of under quality, the limited situation of volume that the purpose of this utility model is to provide, and adopts the efficient infrared signature intensifier of combustion gas as the energy.
Realize the technical scheme of the utility model purpose: a kind of infrared signature intensifier, the radiant body that comprises gas generator, is tightly connected by syndeton and gas generator, this radiant body is for adopting the spherical of individual layer airtight fabric welding, be provided with porous bag in the chamber of radiant body, this porous bag is tightly connected by syndeton and gas generator; Described syndeton comprises two ring flanges, and by screw, nut and two metal threaded covers that ring flange is locked; On the described radiant body relief valve is installed.
Aforesaid a kind of infrared signature intensifier, the spherical of porous bag for adopting vagcor cloth to make is evenly distributed with the hole on its surface.
Aforesaid a kind of infrared signature intensifier, ring flange adopt glass-reinforced plastic material to make.
Effect of the present utility model is: adopt the combustion gas mode of heating of combustion gas as heating source, efficiency of heating surface height, the effective time is long and have control flexibly, balance short advantage Time Created.The utility model can be implemented under existing quality, the volume restrictions condition, forms higher infrared signature.

The specific embodiment
Below in conjunction with drawings and Examples a kind of infrared signature intensifier provided by the utility model is further described.
As shown in Figure 1, a kind of infrared signature intensifier, comprise gas generator 2, by the radiant body 1 that syndeton 3 and gas generator 2 are tightly connected, be provided with porous bag 4 in the chamber of radiant body 1, this porous bag 4 is tightly connected by syndeton 3 and gas generator 2; Described syndeton 3 comprises two ring flanges 7, and by screw 10, nut 9 and two metal threaded covers 8 that ring flange 7 is locked; On the described radiant body 1 relief valve 5 is installed.
Radiant body 1 is the spherical that is welded into by the individual layer airtight fabric as characteristic present's carrier of infrared signature intensifier, and it is tightly connected by syndeton 3 and gas generator 2.Gas generator 2 is the heating energy source of infrared signature intensifier, can directly from present general gas generator, choose, as shown in Figure 3, a kind of gas generator of selecting for use comprises metal shell 15, powder charge 11, dividing plate igniter 12, igniter cartridge 13 and jet pipe sleeve pipe 14.As shown in Figure 4, syndeton 3 is used to realize radiant body 1 and gas generator 3, and being tightly connected of porous bag 4 and gas generator 3.Concrete connected mode is: radiant body 1 and porous bag 4 are installed between two ring flanges 7 of syndeton 3 together, lock by screw 10, nut 9 with metal threaded cover 8; The jet pipe sleeve pipe 14 of gas generator 2 is threaded with metal threaded cover 8.The ring flange 7 of syndeton 3 is selected glass-reinforced plastic material for use, and it is broken to guarantee that radiant body 1 is not scalded in the contact-making surface of syndeton 3, and radiant body 1 is played the thermal protection effect.As shown in Figure 2, the spherical of porous bag 4 for adopting vagcor cloth to make, be evenly distributed with hole 6 on the surface, this structure is evenly distributed combustion gas in radiant body 1, play thermal protection effect simultaneously to radiant body 1, because the combustion gas skewness can cause the local gas temperature too high, radiant body 1 is caused damage.Pressure in 5 pairs of radiant bodies of relief valve 1 is controlled, and guarantees to remain intact in radiant body 1 in actual working time.
Specific implementation is as follows: the gas that gas generator 2 produces evenly fills in radiant body 1 cavity by porous bag 4.Combustion gas is passed to radiant body 1 by heat exchange methods such as radiation, convection current with energy in the cavity, and radiant body 1 is by the outside emittance of its outer surface simultaneously, and whole process is a thermal balance process, and the irradiator surface temperature maintenance is in scope of design.Gas generator 2 constantly is radiant body 1 inflation, along with gas quantity in the cavity increases, when cavity internal pressure reaches predetermined value, relief valve 5 work, this moment, gas generator 2 raising combustion speed were to remedy the energy loss that relief valve brings, whole process still keeps the thermal balance process, and radiant body 1 surface temperature control is in scope of design.After reaching application demand, gas generator quits work, whole device power cut-off.Compare with correlation technique in the past, the utility model can be implemented under existing quality, the volume restrictions condition, forms higher infrared signature.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.If these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
