Title
Study of the Space Station On-Orbit Leak Detection Based on the Differential Pressure Gas Sensor
Abstract
Studying the space station on-orbit leak detection technology was the important part of manned spacecraft on-orbit detection and security protection technology, and it was also the important way to prevent spacecraft from leaking accident, and very significative for astronauts' life safe. And the detection system consisted of differential pressure gas sensor as the core and interior dissymmetrical datum cubage. Through theory and experimental study, this system leak detection sensitivity, feasibility and validity was summarized. The study conclusions indicate the precision of space station on-orbit leak detection by the differential pressure method is very high, and leak detection sensitivity is about 2.5X10-3Pa·3/s in four hours, and the leak rate which is more than 1X10-2Pa·3/s can be accurately tested in the four hours. What is more, the experiment results show the method is valid and feasible and meets the space station requirements, and these study conclusions apply some references for developing the engineering system in the future.
