In this paper, based on the problem of deflation of large volumetric vessels, this paper proposes an approximate calculation method for calculation of gas pressure variation and exhaust interference force in a container. The ground-based simulation tests and measurement results of the mass flow coefficient of the deflated pipeline system are introduced. The engineering approximate method is popularized and applied to several common one-dimensional gas flow problems in the field of space technology.
