Airproof air cell is the key equipment of leak-testing room at the space launch site. By analyzing the basic structure and elements of the spaceship leak-testing room, the mathematical model of the maximum leaking quantity of the air cell is built, with the theoretical maximum allowed ratio to be 1200Pa/h. An experimental leak-testing system is set up, and 2 air cells are tested and analyzed. Practical experiments indicate that the mathematical model and the testing resuits are precise and reliable.
