Protection type cantilever launching platform with built-in water channel and manufacturing method thereof

Abstract

A protection type cantilever launching platform with a built-in water channel and a manufacturing method thereof are used for launching rockets. The protection type cantilever launching platform comprises a launching platform supporting frame and a fluid director mounted on the launching platform supporting frame, the launching platform supporting frame is provided with a frame internal circulating cooling channel, the fluid director is provided with a fluid director cooling channel which is used for absorbing fuel gas heat which is transmitted through a fluid guide plate of the fluid director to lower the temperature inside and outside the fluid guide plate, the frame internal circulating cooling channel is communicated with the fluid director cooling channel, the frame internal circulating cooling channel is provided with a cooling liquid inlet and a cooling liquid outlet respectively, and cooling liquid enters from the cooling liquid inlet, circulates along the frame internal circulating cooling channel and the fluid director cooling channel and then is discharged from the cooling liquid outlet. The manufacturing method comprises the steps of arranging the saddle-shaped guide director, arranging the cantilever launching platform supporting frame and assembling the cantilever platform.

Description

technical field [0001] The invention relates to rocket launch technology, in particular to a cantilever launch platform with built-in waterway protection and a manufacturing method thereof for rocket launch. Background technique [0002] The Chinese patent application with the application number "99124578" and titled "Launching Pad Booster Rocket Launching Method" discloses a rocket launching method, but does not specify the structure of the launching pad. At present, the mobile launch of rockets is limited to mobility requirements. In the prior art, the launch pad for launching rockets is often designed as a cantilever launch pad, which is convenient for randomly deploying the launch pad during the rocket maneuvering process to launch the rocket, and quickly recovering the launch pad after the rocket launch. Evacuate to standby position. The launch pad is designed as a cantilever type, and its highly compact structure has become a major feature. Otherwise, the rocket maneu...

Problems solved by technology

[0004] At present, the cantilever launch pad has developed a series of thermal protection technologies, mainly based on two directions. One is to seek a reasonable flow diversion method to avoid or reduce the impact of the launch pad and rocket launch vehicle support structure on the exhaust gas flow. At present, a series of double-sided thermal protection technologies have been developed. , single-sided diversion profile, there are still many areas worthy of research in the optimization and reasonable selection of these profiles, especially in launch positions where the range of gas drainage is strictly limited for rocket mobile launches, the traditional double-sided and single-sided diversion type The surface must be improved; the second is to seek reasonable thermal protection materials, use thermal protection materials to resist the ablation and damage of high heat flow gas flow, and delay the rapid transfer of high heat flow to the structure of the launching platform, mainly developing thermal insulation composite materials or coatings, However, the anti-ablation life of thermal insulation composite materials or coatings is limited, and the repairability has also become a big problem in the maintenance of the launch pad. Therefore, seeking a more reasonable thermal protection method has become a new research topic.
