Description

Technical Field

[0001] This invention belongs to the field of launch technology, specifically relating to a launch system with a centrally erected telescopic concentric tube. Background Technology

[0002] To improve the survivability of land-based mobile rocket launchers, the rockets must possess excellent mobility and rapid response capabilities. The launch process for mobile rockets includes preparation, leveling, erection, and launch. The long leveling time required for the mobile platform severely limits the rapid response capability of land-based mobile rocket launches. Traditionally, rockets are launched from the rear of the mobile platform, with the ejection load primarily borne by the launch pad. When the rocket is launched from the middle of the mobile platform, the platform struggles to withstand the ejection load. To enhance the rapid response capability of land-based mobile rocket launches and thus improve the rocket's survivability, a center-erecting, telescopic concentric tube launch system can be employed.

[0003] By using the intermediate erection module to erect the rocket to the center of the vehicle-mounted launch platform, the ejection load during the launch process can be evenly distributed to the chassis and tires, replacing the traditional leveling outriggers to bear the load. This eliminates the need for additional leveling time, simplifies the preparation process for vehicle-mounted rocket launches, and shortens the pre-launch preparation time. However, the vehicle-mounted platform is difficult to withstand the ejection load during intermediate launches using traditional launch methods. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of current launch systems, such as excessively long pre-launch preparation times and insufficient rapid response capabilities of vehicle-mounted rockets. It provides a telescopic concentric tube launch system with an intermediate erection module, enabling the rocket to be quickly and smoothly erected to a vertical launch position. The telescopic concentric tube module reduces the ejection load and its impact on the vehicle-mounted launch platform. To solve the above problems, a telescopic concentric tube module is used: during launch, the inner tube ejects from the outer tube along with the rocket and is braked by the arresting cable, extending the effective distance of the ejection load. This allows the ejection load to be reduced while maintaining the rocket's exit position, thus minimizing its impact on the vehicle-mounted launch platform.

[0005] To achieve the above objectives, the specific technical solution adopted by the present invention is as follows:

[0013] The inner cylinder 8 is nested inside the outer cylinder 7 to form a concentric cylinder structure, and the inner cylinder 8 can move along the axis inside the outer cylinder 7;

[0014] An arresting cable 28 is provided between the outer cylinder 7 and the inner cylinder 8. Multiple arresting cables 28 are evenly distributed between the outer cylinder 7 and the inner cylinder 8 around the cylinder axis. The arresting cable 28 is used to prevent the inner cylinder 8 from being ejected from the outer cylinder 7 along with the rocket.

[0015] The arresting cable 28 is placed inside the outer cylinder 7. At this time, one end of the arresting cable 28 is connected to the outer cylinder 7 and the other end is connected to the inner cylinder 8. The connection can be fixed, hinged, or other methods. When the inner cylinder 8 moves inside the outer cylinder 7, the arresting cable 28 gradually straightens and brakes the inner cylinder 8.

[0019] A telescopic concentric tube launching system with intermediate erection is provided. In the transport state, the erecting frame 3 and the outer tube 7 are in a horizontal state; during the erection process, the erecting frame 3 and the outer tube 7 are in an inclined state.

[0020] The front-mounted erecting cylinder 1 and the rear-mounted flat-push cylinder 2 extend together. The front-mounted erecting cylinder 1 pushes the erecting frame 3 to rotate clockwise around the movable base support lug 18. The rear-mounted flat-push cylinder 2 pushes the movable base 5 to slide along the slide groove 4 towards the front end through the C-shaped component 10.

[0021] When the erection is completed, the erection frame 3 and the outer cylinder 7 are in a vertical state; the front erection cylinder 1 and the rear push cylinder 2 extend to the predetermined length and lock, and the axis of the outer cylinder 7 is aligned with the axis of the moving base 5 and placed vertically on the moving base.

[0022] During launch, the inner cylinder 8 is ejected from the outer cylinder 7 along the axis of the rocket. Just as the inner cylinder 8 is about to leave the outer cylinder 7, the arresting cable 28 gradually straightens and brakes the inner cylinder 8, allowing the rocket to exit the cylinder.

[0023] The telescopic concentric tube launch system of the present invention, during erection, elevates the rocket to the center of the vehicle-mounted launch platform via a central erection module. This allows the ejection load during launch to be evenly distributed across the chassis and tires, replacing the traditional leveling outriggers to bear the load. This eliminates the need for additional leveling time, simplifies the preparation process for vehicle-mounted rocket launches, and shortens pre-launch preparation time. However, the vehicle-mounted platform cannot withstand the ejection load during intermediate launches using traditional methods. To address this issue, a telescopic concentric tube module is employed: during launch, the inner tube ejects from the outer tube along with the rocket and is braked by the arresting cable, extending the effective distance of the ejection load. This allows the ejection load to be reduced while maintaining the rocket's exit position, thus minimizing its impact on the vehicle-mounted launch platform.

[0024] The beneficial effects of this invention are as follows:
