[0002] The fixed launch platform for rockets is a crucial piece of ground equipment in a launch system. Its primary functions include supporting and transporting the rocket and payload, adjusting verticality, and directing gas flow. Located at the base of the rocket body, the launch platform supports the entire weight of the rocket body and its fuel. During launch missions, the high-temperature, high-velocity gas jets from the rocket engine cause significant ablation and erosion of the launch platform, reducing its service life. Therefore, thermal protection of the launch platform surface is crucial for improving its operational safety and extending its lifespan. It also plays a significant role in reducing noise during launch.

[0003] Cooling and noise reduction of rocket launch platforms require high-flow water spraying in a short period of time through the water supply system. The water supply system must meet the demand for short-term high-flow, so thick and long water pipes are usually used to transport water at a very fast speed. During operation, the pressurized water flow is prone to generate shock waves, which will cause damage to the pipe wall; and the water flow of the existing water supply system is difficult to control, the water spraying range is small, and the cooling and noise reduction are not good; rocket launch platforms will undergo routine inspections and maintenance before launch, but the existing water supply system pipelines all adopt a fixed and basic structure, which is very inconvenient to inspect and maintain the nozzles and nozzles.

Cooling water is sprayed through the high nozzle 9 and the low nozzle 10 to form a larger range of counter-spraying effect, which has a better cooling and noise reduction effect.
