[0002] With the continuous evolution of aerospace technology, aircraft are rapidly developing towards lower cost and reusability. Under this trend, traditional pyrotechnic-driven separation devices are increasingly unable to meet new development demands due to their single-use nature, high cost, storage and operational safety hazards, and the resulting residual pollution and impact effects. As a crucial component of reusable aircraft, recovery systems are facing increasingly stringent requirements for cost control, enhanced safety and reliability, and ease of operation.

[0003] Therefore, adopting non-pyrotechnic technologies to replace traditional pyrotechnics is becoming a clear development direction. These technologies typically offer advantages such as reusability, high controllability, low impact, high safety, and ease of maintenance. They not only effectively reduce life-cycle costs but also improve mission flexibility and operational efficiency, aligning better with the future sustainable development goals of high reliability, low cost, and ease of use for aerospace systems.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Reference Figures 1 to 3 As shown, the present invention provides a cold-propelled parachute rocket, comprising: Connector 2 is connected to the parachute. Connector 2 has a partition plate inside, which divides the interior of connector 2 into a first cavity and a second cavity. A gas storage mechanism is installed on the connecting seat 2, and the gas storage mechanism is located in the first cavity; The sealing mechanism is fixedly connected to the gas outlet of the gas storage mechanism and is used to seal the gas storage mechanism. The jet mechanism is mounted on the connecting seat 2 and is connected to the second chamber. A triggering device 8 is mounted on the connecting seat 2. The triggering device 8 is located inside the second cavity and its triggering end corresponds to the sealing mechanism. A gas flow channel is provided inside the triggering device 8. Before the triggering device 8 breaks the sealing mechanism, the gas storage mechanism is not connected to the second chamber. After the triggering device 8 breaks the sealing mechanism, the gas storage mechanism is connected to the second chamber through the gas flow channel inside the triggering device 8.

[0025] Furthermore, the gas storage mechanism includes a gas cylinder 1, which is disposed in the first cavity. The gas cylinder 1 is fixedly connected to the partition plate by a nut 3, and the sealing mechanism is fixedly connected to the mouth of the gas cylinder 1.

[0026] Furthermore, the sealing mechanism includes a diaphragm 4, which is fixedly connected to the mouth of the gas cylinder 1.

[0027] The gas cylinder 1 is sealed by the diaphragm 4, and the diaphragm 4 is activated by the triggering device 8, which generates thrust through the jet mechanism.

[0028] Furthermore, the end of the second chamber away from the first chamber is fixedly connected to the first end cover 5, and the jet mechanism and triggering device 8 are disposed on the first end cover 5.

[0029] Furthermore, multiple bolts 6 are provided on the first end cap 5, and the umbrella bag is connected to the first end cap 5 by the bolts 6.

[0030] Furthermore, the jet mechanism includes multiple nozzles 7 arranged in an array on the first end cap 5, and the parachute is connected to the second chamber through the nozzles 7.

[0031] Furthermore, the triggering device 8 includes a housing 82, which is fixedly connected to the first end cover 5. A triggering part is provided at one end of the housing 82 near the diaphragm 4, and an activation part is provided at the other end of the housing 82.

[0032] Furthermore, the triggering part includes a piston 83, which is slidably disposed within the housing 82, and a striking pin 81 is fixedly connected to one end of the piston 83 near the diaphragm 4.

[0033] Furthermore, the starting unit includes an ignition head 85, which is fixedly connected to the housing 82 via a second end cap 84.

[0034] The triggering device 8 adopts a modular design for easy installation. The housing 82 has openings on its side wall to connect with the gas flow channel, allowing gas to flow.

[0035] Furthermore, diaphragm 4 is a thin metal sheet.

[0036] When the ignition head 85 is ignited, it pushes the piston 83 and the firing pin 81 to break the diaphragm 4, causing the gas to flow out from the opening in the side wall of the housing 82.

[0037] During final assembly, the present invention fills a predetermined weight of solid or liquid gas, preferably solid carbon dioxide, by weighing. Then, the diaphragm 4 is quickly sealed with a nut 3 and sealed with a polytetrafluoroethylene sealing ring. Then, the connecting seat 2, triggering device 8, bolt 6, nozzle 7, and first end cap 5 are installed. The bolt 6 connects to the parachute pack strap to realize the release of the parachute pack.

[0038] The user directly issues a command signal to activate the parachute rocket, which triggers the ignition head 85 of the triggering device 8. The firing pin 81 punctures the diaphragm 4, and high-pressure gas flows out from the side opening of the shell 82 and is ejected through the nozzle 7, forming thrust. The parachute is then pulled out by the bolt 6 and the parachute pack strap.
