DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The purpose of the present invention is to provide a gas-driven projectile launching device to solve the problems existing in the above-mentioned prior art, with continuously adjustable speed and safe, reliable and easy-to-obtain raw materials.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1-Figure 10 As shown, the present invention provides a gas-driven projectile launching device, which comprises:

[0030] The loading bay 1 has a powder chamber 14 in which energetic materials are loaded, nitrocellulose 16 or standard charges are used as propellant charges, and the propellant charges are ignited by an electronic ignition device.

[0031] The launch tube 2 and the bomb loading compartment 1 ignite the high-pressure gas generated by the propellant charge to drive the projectile body 21 / the sabot to fly out at high speed along the launch tube 2 of 25mm caliber.

[0032] The sabot separator 4 is a device that pneumatically separates the sabot from the projectile body 21.

[0033] The silencer 5 further silences and diverts the high-pressure gas, thereby reducing the impact of the high-pressure gas on the target.

[0034] The laser speed measuring device 9 measures the speed of the projectile 21 in front of the collider target and collects data, such as Figure 5 As shown, the laser speed measuring device 9 is conventional technology and will not be described in detail here.

[0035] The gas-driven projectile launcher also includes components such as a launch tube support 3, an aluminum profile 8, an H-steel base 7, and a base leg 6. The bomb bay 1, the launch tube support 3, the sabot separator 4, the silencer 5, and the laser speed measuring device 9 are fixed in the groove of the aluminum profile 8, and the bomb bay 1, the launch tube support 3, the sabot separator 4, and the silencer 5 are an integrated structure connected by flanges.

[0036] There is a powder chamber 14 in the bomb loading cabin 1, which is used to ignite and detonate the charge and release the high-pressure gas. An ignition mechanism is installed in the powder chamber 14 of the bomb loading cabin 1, and a diaphragm for gas to pass through is installed at the gas outlet end of the powder chamber 14; the ignition mechanism includes a breech block 11, a match head 13 and an ignition power line 10, the breech block 11 is tightened and assembled at the port of the powder chamber 14, the match head 13 is arranged on the breech block 11 and located in the powder chamber 14, an electronic match head lead 12 connected to the ignition power line 10 is arranged on the match head 13, and the outer side of the match head 13 is coated with nitrocellulose 16. The diaphragm adopts a stainless steel diaphragm 15, and the circumference of the stainless steel diaphragm 15 is pressed tightly at the connection between the bomb loading cabin 1 and the launch tube 2, and a cross scratch is arranged in the middle of the stainless steel diaphragm 15, and the gas in the powder chamber 14 passes through the cross scratch and enters the launch tube 2.

[0037] The propellant uses nitrocellulose 16 as a raw material, which is easy to purchase, has reliable safety and low price. At the same time, nitrocellulose 16 belongs to smokeless gunpowder, and there is no dust residue after combustion, which causes less pollution to the launch tube 2 and is easy to clean. By using nitrocellulose 16 or standard charge as the propellant charge, the price of nitrocellulose 16 is cheap, and no smoke is generated during the use process, which is helpful for cleaning the launch tube 2 after the experiment and reduces pollution to the environment.

[0038] The gas-driven projectile launcher of the present invention uses a stainless steel diaphragm 15 in the gunpowder chamber 14 and the ignition device of the loading cabin 1 to control the release of high-pressure gas. After the electronic match head lead 12 is powered and heated by a remote-controlled DC starter, the heat accumulation causes the nitrocellulose 16 to ignite. When the pressure of the released high-pressure gas reaches the release pressure of the stainless steel diaphragm 15, the stainless steel diaphragm 15 cracks to release the high-pressure gas, driving the cartridge case and the projectile 18 to accelerate and fly out along the launch tube 2. By regulating the remaining thickness of the cross notch of the stainless steel diaphragm 15 and the amount of charge, the speed of the projectile 21 can be effectively controlled; the speed of the projectile 21 is directly controlled by the amount of gunpowder at low speed; through the above method, the launch speed of the projectile 21 of the device of the present invention is continuously adjustable, stable and reliable.

[0039] In one of the embodiments, the sabot separator 4 at the end of the launch tube 2 is connected to the launch tube 2 by a flange, and the flange is used to facilitate the future docking with the target cabin; the sabot separator 4 adopts a thick-walled tube structure, one end of which has an exhaust hole, and the other end is connected to the muffler 5 flange. The inner hole of the muffler 5 has an easily replaceable partition, and the partition is fixedly connected by radially distributed bolts; there are circumferentially distributed air leakage holes for blocking flow between the partitions of the muffler 5 to reduce the impact of high-pressure airflow on the damage of the target. A porous muffler 5 device is added to the outside of the sabot separator 4. After the sabot separation device pneumatically separates the sabot and the projectile 21, the high-pressure gas is further silenced and diverted through the porous muffler 5 device to reduce the impact of the high-pressure gas on the target, thereby improving the accuracy of the experiment.

[0040] like Figure 6-Figure 7 As shown, the end of the muffler 5 and the butt separator 4 flange connection is equipped with a conical butt separation head, which is installed when the butt is fired to separate the butt. When the integral projectile 21 is fired, the conical butt separation head is removed.

[0041] In one embodiment, the supporting structure is composed of a base and base legs 6 made of aluminum profiles 8 and H-steel. The part of the base legs 6 that contacts the ground has a fixed supporting mechanism with adjustable height. At the same time, the base legs 6 have rollers with adjustable height to facilitate the rapid movement of the device.

[0042] The specific use process of the gas-driven projectile launching device of the present invention is as follows:

[0043] First, connect the sabot separator 4 and the silencer 5 together, and connect the sabot separator 4 to the outlet end of the launch tube 2 by bolts; if a scaled model is to be launched, the sabot separator cone head (such as Figure 6 ) Place the end of the sabot separator 4, that is, place it in the inner hole at the front end of the silencer 5, see Figure 7 As shown. Use cleaning cotton yarn and alcohol to wipe the launch tube 2 clean, and place the projectile 21 (including the bullet support) to be launched at the entrance of the launch tube 2.

[0044] Secondly, place the selected stainless steel diaphragm 15 in the membrane breaker, place various sealing O-rings, and fix them with bolts; then put the stainless steel diaphragm 15 into the outlet of the bomb loading cabin 1, and place the stainless steel diaphragm 15 between the gunpowder chamber 14 and the launch tube 2, and press them between the gunpowder chamber 14 and the launch tube 2 when they are connected; connect the launch tube 2 and the bomb loading cabin 1 tightly together by fastening the nut, and check whether the target is installed reliably. Coaxially place the laser aiming device at the outlet end of the silencer 5, and after determining the position of the impact point of the projectile 21 on the target, remove the laser aiming device.

[0045] Then, according to the actual demand of the speed of the projectile 21, weigh a certain mass of nitrocellulose particles and place them in a plastic bag for standby; put the electronic match head and a nitrocellulose grain into the plastic bag containing nitrocellulose 16 through magic paper packaging, and tie them with fine copper wire, connect a multimeter with a section of wire with insulating skin, check whether the detonating fuse of the breech block 11 is reliably connected to the detonator, otherwise check whether there is any insulation left over from high-temperature burning at the end of the detonating wire, and remove it. Connect the fuse of the electronic match head to the detonating power line 10 of the breech block 11 at the end of the bomb compartment 1, and fix the plastic bag filled with medicine to the breech block 11 with tape, and check whether the sealing ring at the front end of the breech block 11 is intact and whether the detonating wire is in good contact.

[0046] Finally, the breech block 11 is connected to the bomb compartment 1 through a threaded connection, and after tightening, the fuse of the detonator is connected to the detonating wire of the breech block 11, and then the firing is ready. Check whether the laser speed measurement system is in the test state; after all checks are completed, connect the detonation controller to the detonating wire of the breech block 11; further check the surrounding environment and whether there are people and various animals nearby, and effectively clear the area; after everything is ready, turn on the power switch of the detonator, and the detonator control personnel enter the safety protection room, remotely control the detonator, detonate, and record the speed measurement data, thus completing a test.
