|
Abstract:
以CZ-5、CZ-7为代表的我国新一代低温液体运载火箭，对箭体结构防水、防结冰功能提出了更高要求。通过介绍超疏水现象的原理及应用背景，简述我国运载火箭箭体结构防水、防结冰设计现状，并通过试验研究超疏水涂层对于运载火箭结构的防水、防结冰应用效果及环境适应性，验证了涂层对箭体表面小缝隙具有良好的防水效果，对结冰情况有一定的改善，为研制轻质、高效、多功能的运载火箭箭体结构提出了新的思路。
China’s new generation of cryogenic liquid space launch vehicles, represented by CZ-5 and CZ-7, put forward better requirements for the waterproof and anti-icing functions of the structures. This paper introduced the principle and application of super-hydrophobic phenomenon, and briefly described the current situation of the waterproof and icing-free design of rocket structures in China. Through the tests, the application effect and environmental adaptability of super-hydrophobic coating on the rocket structure were studied, and it was verified that the coating has a good waterproof effect on small cracks of the rocket, and improved the icing condition to some extent. A new idea was proposed for the development of lightweight, efficient and multi-functional rocket structure.
