Problems solved by technology

The implementation process involves issues such as size coordination, interface and sealing, and pipeline fixing between the water spray pipeline system and the launch platform, and the installation is complicated.
At the same time, the internal cooling conditions of the water spray pipeline system cannot be transmitted to the launch platform, and the cooling capacity of the water spray pipeline system cannot be fully utilized, which has the disadvantage of insufficient protection for the body structure of the launch platform

Embodiment Construction

[0020] The present invention proposes a launch platform combining internal and external cooling, which can effectively carry and guide gas jets while cooling the internal frame through built-in flow channels, and actively reduce the strength of jet ablation launch equipment through external water spraying.

[0021] Such as figure 1 and figure 2 As shown, the launch platform includes a platform body 1 and a support arm 2 , and the support arm 2 supports the rocket and transfers the load to the platform body 1 . The table body 1 is provided with a support frame 12 and a diversion hole 11 for gas flow and gas conduction. The support frame 12 includes a central well-shaped beam structure and surrounding end frames. The support frame 12 is processed into a hollow structure interpenetrating to form a built-in The flow channel 3, the built-in flow channel 3 is used as a cooling water flow channel and a water supply channel, and the cooling water enters the built-in flow channel 3 f...

Abstract

A launch platform combining internal and external cooling. The launch platform body is provided with a support frame and diversion holes for gas flow and gas conduction. The support frame is processed into a hollow structure that communicates with each other to form a built-in flow channel. The flow channel serves as a cooling water flow channel and a water supply channel; an array of water spray holes communicating with the built-in flow channel is opened on the upper surface of the support frame and the side wall facing the flow guide hole. The invention not only improves the thermal protection capability of the launch pad body structure, but also reduces the complexity of installation between systems. At the same time, combined with the water spray cooling method on the outer surface, the internal and external cooling of the launch platform is fully realized.

Description

technical field [0001] The invention relates to a launching platform combining internal and external cooling, and belongs to the technical field of rocket launching. Background technique [0002] Water spray cooling of the launch platform is one of the key thermal protection methods of the current launch platform. It mainly adopts the water spray cooling method on the outer surface. At present, a set of water spray pipeline system is generally placed in the launch platform body to transport water to the launch platform to realize Spray water on the launch platform table. The implementation process involves issues such as size coordination, interface and sealing, and pipeline fixing between the water spray pipeline system and the launch platform, and the installation is complicated. At the same time, the internal cooling conditions of the water spray pipeline system cannot be transmitted to the launch platform, and the cooling capacity of the water spray pipeline system cann...
