Abstract

The utility model discloses a hydrogen self-filling false target for radars which is an assembly supplied for the emission and the jettison, comprising a reflecting body with a ball type fan angle, an airway, an automatic hydrogen charging device, an air supplement device, etc. The hydrogen charging device is opened automatically and made the hydrogen rapidly when the utility model is dived into the water. After the separation of the water and the hydrogen, the ball is filled with the hydrogen through the airway to carry the reflecting body with the ball type fan angle into the sky in order to cause the reflecting body with the ball type fan angle to work when the reflecting body with the ball type fan angle achieves a definite height. The air supplement device starts to make the hydrogen slowly to extend the effective working time of the false target under the condition of the air temperature dropped down. The hydrogen self-filling false target can be used for the antiradar camouflage in water. The hydrogen self-filling false target can also be the simulacrum of a ship, a radar bait, a radar target drone, a rescue beacon, a provisional radar navigation mark, etc.

Description

Hydrogen self-filling false target for radar

The present invention is a kind of radar decoy.

In the invention in the past, " the boats and ships analogies " introduced for No. 322921 as american documentation literature.Its weak point is: (1) reflected radar ripple be a ball inscribed triangle reflector, fail to make full use of the spheroid space, the radar cross section is less.(2) the hydrogen self-filling device is a generator from bottom sides water inlet limit reaction, and the contact-making surface of its hydride and water is little, and the hydroxide that the surface generates is difficult to obtain and washes away, and hydrogen manufacturing speed is slower.(3) fill hydrogen and finish after, generator promptly is dropped.When environment temperature descends, when hydrogen temperature also decreases in the ball, the ball internal pressure is descended and the ability of forfeiture strut angle reflector, cause reflector to lose efficacy.

The objective of the invention is to design the assembly that provides can supply emission and jettisoning, ball formula segment angle reflector fills hydrogen fast by the hydrogen self-filling device of an enclosed construction, makes its lift-off certain altitude, forms radar decoy.Making-up air device makes the effective time of its prolongation under temperature decline condition.

Center of the present invention technology and advantage can further be introduced from following accompanying drawing and explanation in detail.

Fig. 1 is the assembly generalized section.

Fig. 2 is the decoy schematic diagram of duty.

Fig. 3 is the generator among Fig. 1, making-up air device and link gear schematic diagram.

Fig. 1 shows: hydrogen self-filling false target for radar is made up of protective cover 1, spheroid 2, wireway 3, flexible sleeve 4, rigid cartridge 5, generator 6, link gear 7 and making-up air device 8.

Protective cover 1 is by 9 docking of two housings. Spring steel bar 10 closes up it and press seal bar 11. The lower edge of protective cover 1 is stuck in the outer ring washer 12 of rigid cartridge 5 upper ends, pins by separating iron 13 out of supply, and press seal circle 14. The spheroid 2, wireway 3 and the flexible sleeve 4 that are the folding state are housed in the protective cover 1.

As can be seen from Figure 2, flexible segment angle reflector 15 is housed in the spheroid 2.For obtaining directionality preferably, reflector 15 is that by an angle body upwards an angle body is downward, six even layouts of angle body along continuous straight runs.Safety valve 16 is equipped with at spheroid 2 tops, and the gas above safe pressure is overflowed.The spheroid lower end is connected with wireway 3.

The anti-folding spring 17 of wireway 3 usefulness compressions is contained on wireway 3 outer walls, to prevent that strand is around feeling suffocated when the gas transmission.Its lower end is connected with flexible sleeve 4.

The length of flexible sleeve 4 is by the height decision of required cooling water inflow and gas-water separation.The energy folding with packaging volume and the weight that reduces device, and has increased the stability of working in water.Filter 19 and check valve 20 are equipped with in flexible cover 18 places, and are connected with wireway 3.The effect of check valve 20 is to make the gas-water separation height that has certain pressure in the flexible sleeve and realize designing, and reduces the volume of rigid cartridge; Make hydrogen charge into spheroid 2 back puffing coolings with certain pressure.After fast aeration finishes, keep the hydrogen of certain pressure to make device can become the carrier of floating grappling spheroid 2 in the flexible sleeve.On the flexible cover 18 suspension ring 21 are housed, lifting is used during for retracting device.Flexible sleeve 4 lower ends are connected with rigid cartridge 5.

As can be seen from Figure 1, rigid cartridge 5 will have enough intensity, to bear emission or the impulsive force when jettisoninging.Have water inlet 23 on its base plate 22.When transportation and stored condition, 24 sealings of water inlet 23 usefulness sealing-plugs.Handle ring 25 and drain cock 26 are housed on the barrel of rigid cartridge 5.

Fig. 3 explanation: the structure and the correlation of generator 6, link gear 7 and making-up air device 8.Generator 6 is fixed on the base plate 22 of rigid cartridge 5 by pillar 27.The hydride 28 of open structure is equipped with in inside, and open structure can make the reaction of itself and water quicken.The reacting hole 29 that designs arrangement by the aeration speed requirement is arranged on the sidewall of generator 6, and elastic sealing door 30.A central tube 31 that has a lot of apertures is equipped with in generator 6 bottoms, and its lower ending opening communicates with the external world.Water intaking valve spring 32 is housed in the central tube 31.The effect of central tube 31 is to make the hydride 28 and the contact-making surface of water to increase, and makes the renewal that is washed of its surface.

Link gear 7 is made up of water inlet valve rod 33, self-locking mechanism 34, inlet valve cap 35, central tube sealing gasket 36, push rod 37, gripper shoe 38, shelves ring 39, pulley 40, stay cord 41, split pin 42, safety plug 43, pass valve stay cord 44 and rope sling 45 etc.The upper end of closing valve stay cord 44 is fixed among Fig. 2 on the flexible cover 18.By a series of interlocking actions of linkage 7, make hydrogen aerator realize automation.

Making-up air device 8 is made up of the hydride 47 of shell 46, tight structure and the lyotrope 48 that seals usefulness, and is fixed on the sidewall of generator 6.Lyotrope 48 is controlled at and dissolves after fast aeration finishes, and makes hydride 47 meet water hydrogen manufacturing.Because hydride 47 structures are tight, and have only end face and water reaction, so reaction speed is slow.The hydride 47 of employing different densities section adapts to the needs of tonifying Qi velocity variations.

The operating process and the course of work of hydrogen self-filling radar decoy are: take off sealing-plug 24, draw back and separate iron 13 out of supply, lift assembly with handle ring 25 and drop in the water.If adopt radiation pattern to throw in, these two actions can be finished by the emitter link gear.After the decoy entry, water enters rigid cartridge 5 from water inlet 23, the flexible cover 18 of original air jack-up in the compression cylinder; protective cover 1 is risen and the outer ring washer 12 of disengaging; restoring force by spring steel bar 10 makes protective cover housing 9 separately, and spheroid 2 and wireway 3 promptly become scattered about the water surface, and flexible sleeve 4 is stretched.When flexible sleeve 4 was elongated to design inflow Len req, valve stay cord 44 was closed in pulling, throws off to prevent loose rope sling 45, extracts safety plug 43, pushed shelves ring 39 open, and pulling push rod 37 is pulled out split pin 42 sealed door 30 is opened.The valve rod 33 of meanwhile intaking moves down under the effect of water intaking valve spring 32, makes central tube sealing gasket 36 leave central nozzle, makes inlet valve cap 35 seal water inlet 23 and pinned by self-locking mechanism 34 simultaneously.At this moment, water is by the aperture and the calcium hydride of hydride 28(as loosening of reacting hole 29 and central tube 31) reaction hydrogen manufacturing.Hydrogen overflows from reacting hole 29, and through the filtration of the cooling of water, gas-water separation, filter 19, reaching behind the certain pressure is open check valve 20: enter spheroid 2 along wireway 3 in the process that rises.After spheroid 2 internal gas pressures reached operating pressure, corner reflector 15 promptly was elevated to desired height, formed radar decoy.The lyotrope 48(such as the carbohydrate of making-up air device 8) when hydride 28 reactions finish, melt away calcium hydride or the aluminum hydride of the hydride 47(of tight structure as being pressed into the different densities section) beginning hydrogen manufacturing tonifying Qi, so that decoy meets the requirements of the effective time.
