Speed is even in more than 20km/s, so the ground simulating of space junk is in spacecraft shield design and validation verification
Occupy indispensable status.And in the ground simulating of space junk, frequently with the transmitting of ultra-high rates of fire technique device
Ultrahigh speed bullet is carrying out bump test.In addition, investigation of materials field is the research with regard to material mechanical performance, research
Be material in the case of the instantaneous actions such as impulse load, various dynamics of the material under high temperature, high pressure, high strain-rate loaded condition
Response, is closely connected with each side such as aviation, blast, detonation, plate armour and protection works, so material mechanical performance is studied
National defense construction is played the role of positive, and transmitted at high speed technology can produce high temperature, high pressure, high strain-rate bar in solid dielectric
Loaded state under part.In a word, the mechanical property for research material under high velocity impact, space device space junk are prevented
Shield, high-pressure physics and kinetic energy Penetrator Weapon etc., research worker constantly pursue new transmitted at high speed technology, to meet the problems referred to above
Requirement.
Based on background above, light-gas gun and other transmitted at high speed technologies, such as explosive detonation lift-off technology, electromagnetic propulsion skill
Art, directional cumulation accelerator art, Laser Driven Flyer Plates technology, electrostatic accelerator technology, plasma speed technology etc. meet the tendency of
And give birth to, various countries all show great interest to ultra-high rates of fire technology, and have been achieved for certain achievement in research, at present
There is part achievement in research to be applied to experimentation, but some technologies due to there is the suitability, acceleration equipment complexity etc.
Series of problems so that their less effectives in actual application.
Gas big gun lift-off technology is High speed load side more universal at present the advantages of strong due to its relatively economical, repeatability
In formula, wherein detonation driven load mode, velocity of shot relies on the indoor detonation pressure of burning, takes higher detonation pressure, more
The diaphragm of big Rupture of Membrane pressure can make the high temperature and high pressure gas after detonation increase the driving pressure of piston.So, in detonation pressure
In the case of identical, the drive efficiency for improving detonation fuel to piston is most important to improving velocity of shot.
The content of the invention
The purpose of the present invention is：A kind of fuel gas detonation driven generator for High speed load is provided, is driven and is occurred
The detonation pressure that device is produced is high to the drive efficiency of bullet, realizes the raising of velocity of shot.
The technical scheme is that：For the fuel gas detonation driven generator of High speed load, it includes：Burning
Room, igniter head, diaphragm and transmitting tube；
Combustor is the tubular structure that one end open is closed in one end；Igniter head is arranged on the blind end center of combustor；
Injecting hole is provided with the side-walls of combustor；
Tubular structure of the transmitting tube for both ends open, its one end are docked with the opening of combustor, and joint is provided with diaphragm；
Transmitting tube passes through to fasten barrel realization fixation with the joint of combustor；
Bullet is located at transmitting tube interior diaphragm place end；Before test, by injecting hole to the indoor successively injection combustible gas of burning
Body and oxygen, after setting time, produce detonation by igniter head igniting.
Beneficial effect：(1) present invention effectively improves drive efficiency of the detonation pressure to bullet, so that velocity of shot is significantly
Improve；Fuel gas pressure is filled with by control, velocity of shot 300-3000m/s velocity intervals are realized.
(2) present configuration is simple, environmental protection, good reliability, and repeatability is strong, applied widely.
Description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is bullet magnetic survey speed oscillograph information data figure.
Specific embodiment
Develop simultaneously embodiment below in conjunction with the accompanying drawings, describes the present invention.
Referring to accompanying drawing 1, for the fuel gas detonation driven generator of High speed load, it includes：Combustor 1, igniter head
2nd, diaphragm 3 and transmitting tube 5；
Combustor 1 is the tubular structure that one end open is closed in one end；Igniter head 2 is arranged on the blind end center of combustor 1
Place；Injecting hole 6 is provided with the side-walls of combustor 1；
Tubular structure of the transmitting tube 5 for both ends open, its one end are docked with the opening of combustor 1, and joint is provided with film
Piece 3；Transmitting tube 5 passes through to fasten the realization fixation of barrel 7 with the joint of combustor 1；
Bullet 4 is located in transmitting tube 5, and near diaphragm 3；Before test, successively injected into combustor 1 by injecting hole 6
Fuel gas and oxygen, after setting time, produce electric spark by 2 external direct current power supply of igniter head, and fuel gas occurs detonation,
Detonation wave is gradually propagated to 1 oral area of combustor, pressure sharp increase in combustor 1, and when pressure reaches marginal value, diaphragm 3 breaks
Film, high temperature and high pressure gas drive bullet 4 to launch.
In this example, 1 long 1190mm of combustor, internal diameter 160mm, 5 long 3500mm of transmitting tube can be chosen not according to test requirements document
With the transmitting tube 5 of bore.General, the transmitting bore of transmitting tube 5 is bigger, and 4 size of bullet is bigger, and bullet speed is lower；Transmitting tube 5 is launched
Bore is less, and 4 size of bullet is less, and bullet speed is higher.Burn indoor 1 fuel gas charge controllable, highest can make can in combustor 1
With oxygen mixed gas pressure up to more than ten MPas, up to hundreds of MPa, high temperature and high pressure gas are promoted detonation pressure peak value combustion gas body
4 emission rate of bullet is up to 3000m/s.Fuel gas quality is filled with by reducing being filled with combustor 1, drops can detonation pressure
It is low, realize that bullet hundred meters/s magnitudes low speed is launched, therefore, the quality of fuel gas and oxygen in combustor 1 is filled with by control,
Achievable bullet 300-3000m/s scope emission rates.As shown in Fig. 2 the present invention is launched using magnetic survey speed oscillograph
Bullet tests the speed, and speed can reach 2.74Km/s.
