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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

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

[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 implementation methods.

[0029] like Figures 1-10 As shown, the utility model provides a gas-driven projectile launching device, which includes:

[0030] The loading chamber 1 is loaded with energetic materials in the powder chamber 14 of the loading chamber 1, and nitrocellulose 16 or standard charge is used as the propellant charge, which is ignited by an electronic ignition device.

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

[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-powered projectile launcher also includes components such as a launch tube support 3, an aluminum profile 8, an H-steel base 7, and base legs 6. The ammunition bay 1, launch tube support 3, sabot separator 4, silencer 5, and laser velocity measuring device 9 are fixed within the grooves of the aluminum profile 8. The ammunition bay 1, launch tube support 3, sabot separator 4, and silencer 5 are an integrated structure connected by flanges.

[0036] The loading bay 1 contains a powder chamber 14, which is used to ignite the explosive charge and release high-pressure gas. The powder chamber 14 of the loading bay 1 is equipped with an ignition mechanism, and the gas outlet of the powder chamber 14 is equipped with a diaphragm for gas to pass through. The ignition mechanism includes a breech block 11, a match head 13, and an ignition power cord 10. The breech block 11 is screwed onto the end of the powder chamber 14. The match head 13 is mounted on the breech block 11 and located within the powder chamber 14. The match head 13 is equipped with an electronic match head lead 12 connected to the ignition power cord 10. The outer surface of the match head 13 is coated with nitrocellulose 16. The diaphragm is a stainless steel diaphragm 15, which is compressed around the circumference of the stainless steel diaphragm 15 at the connection between the loading bay 1 and the launch tube 2. The center of the stainless steel diaphragm 15 is provided with a cross-shaped notch, through which the gas in the powder chamber 14 enters the launch tube 2.

[0037] The propellant is made of nitrocellulose 16, a material that is easily available, reliable, safe, and inexpensive. Furthermore, nitrocellulose 16 is a smokeless powder that leaves no dust residue after combustion, resulting in minimal pollution to the launch tube 2 and making it easy to clean. Using nitrocellulose 16 or a standard charge as the propellant charge is inexpensive and produces no smoke or dust during use, facilitating post-experiment cleaning of the launch tube 2 while also reducing environmental pollution.

[0038] The gas-driven projectile launcher of the present invention uses a stainless steel diaphragm 15 in the powder chamber 14 and ignition device of the loading bay 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 accumulated heat 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, releasing the high-pressure gas and driving the sabot and projectile 18 to accelerate out of the launch tube 2. By regulating the remaining thickness of the cross-notch of the stainless steel diaphragm 15 and the amount of powder charge, the speed of the projectile 21 can be effectively controlled; at low speeds, the speed of the projectile 21 is directly controlled by the amount of powder charge. Through the above method, the launch speed of the projectile 21 of the present invention device is continuously adjustable and stable and reliable.

[0039] In one embodiment, the sabot separator 4 at the end of the launch tube 2 is connected to the launch tube 2 by a flange, which facilitates future docking with the target capsule. The sabot separator 4 adopts a thick-walled tube structure, one end of which has an exhaust hole, and the other end is flange-connected to the muffler 5. The inner hole of the muffler 5 has an easily replaceable partition, which is fixed with radially distributed bolts. The muffler 5 has vent holes distributed circumferentially between the partitions to reduce the impact of high-pressure airflow on the target. A porous muffler 5 device is added to the outside of the sabot separator 4. After the sabot separator separates the sabot and the projectile 21 pneumatically, the high-pressure gas is further silenced and diverted through the porous muffler 5 device, reducing 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 sabot separator 4 flange connection is equipped with a conical sabot separation head, which is installed when the sabot is launched to separate the sabot. When the entire projectile 21 is launched, the conical sabot separation head is unloaded.

[0041] In one embodiment, the support 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 support 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 launcher in this utility model is as follows:

[0043] First, connect the sabot separator 4 and the silencer 5 together, and connect the sabot separator 4 to the exit end of the launch tube 2 by bolts; if you want to launch a scale model, you should separate the sabot cone head (such as Figure 6 ) Place the end of the sabot separator 4, that is, in the inner hole at the front end of the muffler 5, see Figure 7 Use cotton yarn with cleaning head and alcohol to wipe the launch tube 2 clean, and place the projectile 21 (including the sabot) to be launched at the entrance of the launch tube 2.

[0044] Next, place the selected stainless steel diaphragm 15 in the membrane breaker, insert any sealing O-rings, and secure with bolts. Next, place the stainless steel diaphragm 15 at the exit of the loading bay 1, between the powder chamber 14 and the launch tube 2. When the powder chamber 14 and launch tube 2 are connected, the stainless steel diaphragm 15 is compressed between them. Using a quick-screw nut, tightly connect the launch tube 2 and loading bay 1. Check that the target is securely installed. Coaxially place the laser aiming device at the exit of the silencer 5. After determining the impact point of the projectile 21 on the target, remove the laser aiming device.

[0045] Then, based on the actual speed requirements of the projectile 21, weigh a certain amount of nitrocellulose granules and place them in a plastic bag for later use. Wrap an electronic match head and a nitrocellulose granule in magic paper and place them in the plastic bag containing the nitrocellulose 16. Tie them together with fine copper wire and connect them to a multimeter using a length of insulated wire. Check that the detonating fuse of the breech block 11 is securely connected to the detonator. If not, check the end of the detonating wire for any insulation left over from high-temperature combustion 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 loading bay 1. Secure the plastic bag containing the explosives to the breech block 11 with tape. Also, check that the sealing ring at the front end of the breech block 11 is intact and that the detonating wire is in good contact.

[0046] Finally, thread the breech block 11 to the loading bay 1, tighten the screws, and connect the detonator's fuse to the detonating wire of the breech block 11, ready for firing. Check that the laser velocity measurement system is in the test state. Once all checks are complete, connect the detonator controller to the detonating wire of the breech block 11. Further check the surrounding environment to see if there are any people or animals nearby, ensuring they are effectively cleared. Once everything is ready, turn on the detonator's power switch. The detonator controller enters the safety room and remotely controls the detonator to detonate the weapon, recording the velocity data. This completes the test.
