Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ejection devices, and discloses a gas bag type phase change cold ejection device and method. BACKGROUND

[0002] At present, the ejection technology mostly adopts a gas-launching-tube ejection device, as shown in the figure. Figure 1 The device mainly comprises an ejection tube 101, a guide rail 102, an adapter 103, an ejection carrier 104, an ejection support 105, a gas generator 106, a jet pipe 107, an initial container chamber 108, a flow guide cone 109 and a flexible base 110.

[0003] The ejection carrier 104 is fixedly connected with the adapter 103 and is placed in the ejection tube 101 as a whole, and the adapter 103 and the guide rail 102 form a sliding pair in cooperation. The ejection carrier 104 is in contact with the ejection support 105 at the end, high-pressure gas generated by the gas generator 106 is injected into the initial container chamber 108 through the jet pipe 108, and after uniform pressure in the initial container chamber 108, flow division by the flow guide cone 109 and reflection by the flexible base 110, the ejection support 105 is pushed to drive the ejection carrier 104 to move along the guide rail 102.

[0004] The ejection of the gas-launching-tube ejection device effectively improves the speed and range of the ejection carrier relative to self-launching, but the device still has the following problems:

[0005] 1. High maintenance and use cost. In order to meet the ejection speed of the ejection carrier, a long acceleration stroke launching tube is usually used, which is difficult to guarantee the parallelism, cylindricity and other technical requirements and has a very high production cost. The high-temperature gas purchased as the ejection medium has a burning phenomenon on the inner wall of the launching tube, reduces the number of repeated use of the ejection, and increases the use cost.

[0006] 2. Poor concealment of ejection. During ejection operation, the high-temperature gas continuously generated by the ejection device drives the ejection carrier to move and is finally discharged to the surrounding environment, which is easy to be detected and weakens the battlefield survival ability of the ejection equipment to some extent.

[0007] 3. Cannot adapt to multiple ejection carriers. Due to the constraint of the diameter of the launching tube, it cannot adapt to ejection carriers larger than the diameter of the tube.

[0008] Therefore, the above-mentioned defects of the existing gas-launching-tube ejection device are the technical problems to be solved at present. SUMMARY

[0020] When the phase-change power device is excited, the high-pressure phase-change gas generated from the phase-change power device is jetted into the primary chamber composed of the airbag and the base through the jet pipe, the primary chamber expands rapidly under the action of the continuously jetted high-pressure phase-change gas, the launching carrier and the adapter move rapidly upward at high speed along the guide rail, and the recoil force is transmitted to the ground through the base;

[0037] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0038] like Figure 2 As shown, the first embodiment of the present invention proposes an airbag-type phase change cold ejection device, including an ejection frame 201, a guide rail 202, an adapter 203, an ejection carrier 204, an airbag 205, a pressure relief valve 210, and a base 211. The guide rail 202 is installed inside the ejection frame 201, and the adapter 203 is arranged on the inner wall of the guide rail 202. The ejection carrier 204 and the adapter 203 are fixedly connected to each other and can move linearly together along the guide rail 202. The lower side of the airbag 205 is installed on the base 211, and a pressure relief valve 210 is installed on one side of the airbag 205. During the ejection operation, the airbag 205 expands rapidly under the action of the phase change high-pressure gas and pushes the ejection carrier 204 to move linearly along the guide rail 202. After the ejection is completed, the phase change high-pressure gas in the airbag 205 is depressurized through the pressure relief valve 210 and discharged into the surrounding environment.

[0039] In the above structure, please see Figures 2 to 4The airbag-type phase change cold ejection device provided in this embodiment further includes a phase change power device 206, an injection pipe 207, a primary chamber 208, and a guide cone 209. The phase change power device 206 is connected to the primary chamber 208 through the injection pipe 207, and the guide cone 209 is located below the injection pipe 207. The phase change power device 206, the injection pipe 207, and the guide cone 209 are all built into the airbag 205. The injection pipe 207 is installed at the airflow outlet of the phase change power device 206. The guide cone 209 is installed on the base 211. The airbag 205 and the base 211 together form the primary chamber 208. The outer circumference of the adapter 203 cooperates with the guide rail 202 to form a sliding pair. Multiple adapters 203 are evenly arranged at intervals along the outer circumference of the ejection carrier 204. The airbag-type phase change cold ejection device provided in this embodiment adopts an airbag-type cold ejection scheme, eliminating the need for a launch tube and significantly reducing ejection costs. The use of high-pressure phase change gas ejection prevents ablation of the inner wall of the launch tube, increasing the number of times the ejection can be reused and reducing maintenance and operating costs. During airbag-type cold ejection operations, no high-temperature gas is injected into the launch tube, making the ejection device less susceptible to detection and enhancing its battlefield survivability.

[0040] The present invention also provides a gasbag-type phase change cold ejection method, applied in the gasbag-type phase change cold ejection device as described above. The gasbag-type phase change cold ejection method includes the following steps:

[0041] In step S100, when the phase change power device is not activated, all components are in their initial positions.

[0042] like Figure 2 As shown, when the phase change power device 206 is not activated, all components are in their initial positions.

[0043] In step S200, when the phase change power device is activated, the phase change high-pressure gas generated by the phase change power device is injected through the injection pipe into the initial chamber composed of the air bag and the base. Under the action of the continuously injected phase change high-pressure gas, the initial chamber expands rapidly, pushing the ejection carrier and adapter to move rapidly upward at high speed along the guide rail. The resulting recoil force is transmitted to the ground through the base.

[0044] like Figure 3 As shown, the phase change power device 206 is activated, and the phase change high-pressure gas is ejected from the phase change power device 206 through the injection pipe 207 towards the initial chamber 208 composed of the airbag 205 and the base 211. Under the action of the continuously ejected phase change high-pressure gas, the initial chamber 208 expands rapidly, pushing the ejection carrier 204 and the adapter 203 to move rapidly upward at high speed along the guide rail 202. The resulting recoil force is transmitted to the ground through the base 211.

[0045] In step S300, when the ejector carrier moves to the end of the ejector frame, the phase change power device has stopped being activated, the airbag has expanded to the set ejection stroke, and the ejector carrier and the upper surface of the airbag are no longer in contact.

[0046] like Figure 4 As shown, when the ejection carrier 204 moves to the end of the ejection frame 201, the phase change power device 206 has stopped being activated, the airbag 205 has expanded to the set ejection stroke, and the ejection carrier 204 and the upper surface of the airbag 205 are no longer in contact.

[0047] Step S400: After ejection is completed, the phase change high-pressure gas is discharged to the atmosphere through the pressure relief valve.

[0048] like Figure 4 As shown, after ejection, the phase change high-pressure gas is discharged to the atmosphere through the pressure relief valve 210.

[0049] Step S500: After the ejection operation is completed, the ejection device is inspected, maintained and repaired.

[0050] After the ejection operation is completed, the ejection device undergoes overall inspection, maintenance, and upkeep to effectively ensure the reliability of the ejection.

[0051] like Figures 1 to 4 As shown, the working principle of the airbag-type phase change cold ejection method provided in this embodiment is as follows:

[0052] The overall structure of the airbag-type phase change cold ejection is as follows: Figure 2 As shown, it mainly consists of a catapult frame 201, a guide rail 202, an adapter 203, a catapult carrier 204, an airbag 205, a phase change power device 206, a jet pipe 207, a primary chamber 208, a guide cone 209, a pressure relief valve 210, and a base 211.

[0053] Please see Figure 2 The guide rail 202 is installed inside the ejection frame 201. The ejection carrier 204 and the inner circumference of the adapter 203 are fixedly connected to each other, and the outer circumference of the adapter 203 cooperates with the guide rail 202 to form a sliding pair. During ejection, the ejection carrier 204 can move linearly along the guide rail 202 together with the fixed adapter 203. The airbag 205 is mounted on the base 211 on its lower side. A pressure relief valve 210 is installed on the side of the airbag 205. During ejection, the airbag expands rapidly under the action of phase change high-pressure gas and pushes the ejection carrier 204 to move linearly along the guide rail 202. After ejection, the phase change high-pressure gas in the airbag 205 can be depressurized through the pressure relief valve 210 and discharged into the surrounding environment.

[0054] like Figure 3As shown, the phase change power device 206 is built into the airbag 205, the injection pipe 207 is installed at the airflow outlet of the phase change power device 206, and the guide cone 209 is installed on the base 211. When the phase change power device 206 is activated, the high-pressure phase change gas is injected into the primary chamber 208 through the injection pipe 207 and flows into the guide cone 209. After being diverted by the guide cone 209, the high-pressure phase change gas is pressure-equalized in the primary chamber 208 and then pushes the upper surface of the airbag 205 and the ejection carrier 204 upward rapidly along the guide rail 202 to perform the ejection operation.

[0055] During airbag-type cold ejection operations, the phase change ejection state is as follows:

[0056] 1) When the phase change power device 206 is not activated, all components are in their initial positions, such as... Figure 2 As shown.

[0057] 2) When the phase change power device 206 is activated, high-pressure phase change gas is ejected from the phase change power device 206 through the injection pipe 207 towards the initial chamber 208, which is composed of the airbag 205 and the base 211. Under the action of the continuously ejected high-pressure phase change gas, the initial chamber 208 rapidly expands, propelling the ejection carrier 204 and the adapter 203 to move rapidly upward at high speed along the guide rail 202. The resulting recoil force is transmitted to the ground through the base 211. Figure 3 As shown.

[0058] 3) When the ejection carrier 204 moves to the end of the ejection frame 201, the phase change power device 206 has stopped activating, the airbag 205 has inflated to the set ejection stroke, and the ejection carrier 204 and the upper surface of the airbag 205 have separated. After ejection, the high-pressure phase change gas is discharged to the atmosphere through the pressure relief valve 210.

[0059] 4) After the ejection operation is completed, the ejection device is inspected, maintained and repaired.

[0060] The airbag-type phase change cold ejection device and method provided in this embodiment, compared with the prior art, uses an ejection frame, guide rail, adapter, ejection carrier, airbag, pressure relief valve, and base. The guide rail is installed inside the ejection frame, the adapter is arranged on the inner wall of the guide rail, the ejection carrier and the adapter are fixedly connected to each other and can move linearly along the guide rail together, the lower side of the airbag is installed on the base, and a pressure relief valve is installed on one side of the airbag. During ejection, the airbag expands rapidly under the action of phase change high-pressure gas and pushes the ejection carrier to move linearly along the guide rail; after ejection, the phase change high-pressure gas in the airbag is depressurized through the pressure relief valve and discharged into the surrounding environment. The airbag-type phase change cold ejection device and method provided in this embodiment have the following advantages compared with the existing gas-launch tube ejection device:

[0061] 1. Low maintenance and operating costs. Utilizing an airbag-type cold ejection system, there is no launch tube, significantly reducing ejection costs. The phase-change high-pressure gas ejection system eliminates the risk of ablation on the inner wall of the launch tube, increasing the number of times the ejection can be reused and further reducing maintenance and operating costs.

[0062] 2. Excellent concealment during launch. During airbag-type cold launch operations, no high-temperature combustion gases are ejected into the launch tube, making the launch device difficult to detect and enhancing its battlefield survivability.

[0063] 3. Compatible with various ejection carriers. The airbag-type cold ejection uses a combination of launcher rails and airbags, and is not limited by the diameter of the launch tube. Various ejection carriers can be launched by changing the adapter.

[0064] 4. High reliability. Structurally, it eliminates the need for sabots and ballistic braking devices, simplifying the force transmission path and improving the reliability of catapult operations.
