Summary of the invention
In view of above problem, main purpose of the present invention is to provide a kind of firing range control method and device thereof, by regulating gas flow to adjust breech pressure, can effectively control the range of emission, the journey of deciding that mainly is applicable to control pyrotechnics is launched, and also decides fields such as process control applicable to cannon.
In order to realize above purpose, this kind firing range control method provided by the invention, be to connect a dividing potential drop thorax by establish a dividing potential drop mouth at the rear of gun propellant combustion chamber, and by regulating dividing potential drop thorax space size and dividing potential drop oral pore footpath size, to realize reaching the purpose of range control to doing work in the gaseous-pressure adjustment of bullet.
Propellant powder is being lighted sharply generation chemical change of back, in thorax at the bottom of the limited bullet, discharge a large amount of high-temperature fuel gas and heat energy in the space, form pressure bullet is promoted acting, be converted into the kinetic energy of bullet motion, and, must cause the variation of emission gun pressure at the bottom of the bullet by regulating at the bottom of the limited bullet space and dividing potential drop oral pore footpath in the thorax.
Of the present inventionly also provide a kind of range control device of realizing said method, this device mainly comprises combustion chamber, adjustable transfiguration dividing potential drop thorax, Buffer valve, igniter and cylinder, be provided with a gripper shoe between wherein said combustion chamber and the cylinder, this gripper shoe center offers a bullet mouth again to be communicated with combustion chamber and cylinder, can lay armed bullet on the described bullet mouth; Described adjustable transfiguration dividing potential drop thorax is by being provided with an adjustable piston, realize regulating space size in its thorax, in addition, be provided with a dividing plate again between this adjustable transfiguration dividing potential drop thorax and the combustion chamber, this dividing plate also is provided with a dividing potential drop mouth to be communicated with adjustable transfiguration dividing potential drop thorax and combustion chamber; Described igniter is arranged in sidewall of combustion chamber; Described Buffer valve also is located at respectively on the sidewall of combustion chamber and adjustable transfiguration dividing potential drop thorax, also can be located on the above-mentioned piston, is used to remedy the unstability of heat energy that gun propellant combustion produces and combustion gas; The pore size of described bullet mouth and dividing potential drop mouth all can carry out conversion according to the actual requirements.
This kind range control device provided by the invention, can make a combustion gas part that produces after the gun propellant combustion enter launching tube and promote bullet and do work by the bullet mouth, another part then enters adjustable transfiguration dividing potential drop thorax by the dividing potential drop mouth, realize the acting size of control combustion gas, thereby realize control muzzle velocity degree and range to bullet.
Therefore, this kind firing range control method provided by the invention and device thereof, the journey of deciding that mainly is applicable to control pyrotechnics is launched, also decide fields such as process control applicable to cannon, can effectively control the range of emission, and this invented technology method is simple, easy to use and reliable, be used to control pyrotechnics decide the journey emission time, can realize the appreciation effect of reliably aerial captions and moulding, be applicable to various Festival celebration Festivals, and when being used for cannon and deciding process control, can realize its purpose by control in conjunction with real needs to range.
Description of drawings
Fig. 1 is applied to control the range control device schematic diagram that pyrotechnics is decided the journey emission for the present invention.
The specific embodiment
Below with reference to specific embodiment and accompanying drawing technical scheme of the present invention is further specified, but the qualification of the present invention of not opposing.
This kind firing range control method provided by the invention, connect a dividing potential drop thorax by establish a dividing potential drop mouth at the rear of gun propellant combustion chamber, and by regulating dividing potential drop thorax space size and dividing potential drop oral pore footpath size, to realize reaching the purpose of range control to doing work in the gaseous-pressure adjustment of bullet.
As shown in Figure 1, it is applied to control the range control device schematic diagram that pyrotechnics is decided the journey emission for the present invention, described range control device mainly comprises combustion chamber 10, adjustable transfiguration dividing potential drop thorax 20, Buffer valve 30, igniter 40 and cylinder 50, be provided with a gripper shoe 60 between wherein said combustion chamber 10 and the cylinder 50, these gripper shoe 60 centers offer a bullet mouth 601 again to be communicated with combustion chamber 10 and cylinder 50, can lay armed bullet 501 on the described bullet mouth 601; Described adjustable transfiguration dividing potential drop thorax 20 is by being provided with an adjustable piston 201, realize regulating space size in its thorax, in addition, be provided with a dividing plate 70 again between this adjustable transfiguration dividing potential drop thorax 20 and the combustion chamber 10, this dividing plate 70 also is provided with a dividing potential drop mouth 701 to be communicated with adjustable transfiguration dividing potential drop thorax 20 and combustion chamber 10; Described igniter 40 is arranged in combustion chamber 10 sidewalls; Described Buffer valve 30 also is located at respectively on the sidewall of combustion chamber 10 and adjustable transfiguration dividing potential drop thorax 20, also can be located on the above-mentioned piston 201, is used to remedy the unstability of heat energy that gun propellant combustion produces and combustion gas; Described bullet mouth 601 all can carry out conversion according to the actual requirements with the pore size of dividing potential drop mouth 701.
Bullet lift-off is the result who promotes acting at the bottom of relying on gaseous-pressure in the launching tube thorax to bullet, therefore the size of gaseous-pressure becomes the key factor that determines bullet motion place speed and range at the bottom of the bullet, and the size of gaseous-pressure at the bottom of the bullet, be based on propellant powder and light the chemical change that the back sharply takes place, the a large amount of high-temperature fuel gas and the heat energy that are discharged, and at the bottom of the launching tube thorax and the rapid increase in the confined space between at the bottom of the bullet, must form pressure bullet is promoted acting, be converted into the kinetic energy of bullet motion, therefore, the gun propellant combustion rule just becomes the deciding factor that gaseous-pressure changes at the bottom of the bullet, control combustion gas growing amount and flow, also just controlled the gaseous-pressure at the bottom of the bullet in the thorax, its effect promptly is revealed as the control to bullet launch velocity degree and range.
Below its summary of the invention has been done to elaborate.For persons skilled in the art, any conspicuous change of under the prerequisite that does not deviate from the principle of the invention it being done can not exceed the protection domain of the application's claims.
