对于低轨道长期留轨载人航天器而言,其密封结构在轨期间的密封性能是至关重要的,而由于空间环境条件相对于地面恶劣许多,给密封的监测、检测以及修复带来相当大的困难,为此美、俄等航天大国在空间环境下的密封检测和修复方面进行了大量的研究和试验工作,通过对目前空间环境下密封检测相关技术的了解,综述了不同方法的技术特点,提出我国开展该方面研究的必要性。
For low-orbit long-term orbit manned spacecraft, the sealing performance of the sealing structure during orbit is crucial, and because of the harshness of the space environment conditions relative to the ground, it brings about equivalent to the sealing monitoring, detection and repair Therefore, a great deal of researches and experiments have been carried out on the space sealing and detection and repair of aerospace powers in the United States and Russia. Based on the understanding of the technologies related to seal detection in space environment, the technologies of different methods are summarized Characteristics, put forward the need of our country to carry out research in this area.
