| Abstract: | There are two kinds of methods for the cabin leakage test: flow-rate method and pressure-drop method.The pressure drop method is simple, but leakage rates can not be directly read out.If leakage rates should be determined,interconversion relationship would te used. In this paper, the interconversion of the two kinds of methods for cabin leakage test is established. Leakage rates can be calculated from the method of pressure drop test, andthe time of pressure drop can be calculated from the method of leakage rates test. The application to cabin leakage test is discussed. The concerned charts are established for practical use. |
