China's next-generation large-capacity carrier rocket, the Long March V, made its first flight at Hainan Wenchang Satellite Launch Center. Among them, the high-performance nano aerogel insulation felt product developed by China·s special thermal insulation material manufacturer provides an effective thermal insulation method for the rocket gas pipeline system and provides a strong guarantee for the successful launch.
The engine used by the Long March 5 rocket is the latest generation of high-thrust liquid engine in China, which can provide powerful thrust for the rocket. The gas pipeline of the engine has the characteristics of high operating temperature, narrow space, and complicated structure. If the large amount of waste heat generated during the work is not controlled, it will cause failure of electronic appliances around the pipeline and cause irreversible damage. For this reason, the high-performance nano-aerogel insulation felt product developed by the company is used here, which can effectively limit the excess thermal energy in the pipeline, thereby ensuring the normal operation of the engine.
During the development process, technicians carried out material insulation test research, molding process research and process test research, and finally developed nano-aerogel components that met the design requirements, and successfully passed multiple ground engine test runs, effectively It demonstrates the excellent performance of advanced aerospace materials and escorted the smooth launch of the Long March 5 rocket.
Aerogels are the lightest solid materials known in the world today, with ultra-high specific surface area and extremely low thermal conductivity. For many years, the company has been dedicated to meeting the demand for high-performance thermal insulation composite materials for China's aerospace products, and has developed a series of aerogel materials that cover the temperature range of -130 ℃ to 2500 ℃, which not only solves many problems The key material issues of model equipment have also been promoted and applied in civil fields such as construction, electronics and petrochemicals.
