Abstract
In this paper, using light-gas propulsion technology, a one-dimensional mathematical model is established and simulated numerically for working process of light-gas launching facility with a piston-compressor type. A 30mm/120mm light-gas launcher is taken for the primary computing model, and lots of data, such as the pressure on pump, the piston velocity, the diaphragm failure pressure, etc. are obtained by computing the model in given geometry parameters and loading conditions. According to the numerical results, it is concluded that the developed mathematical model can provide theoretical references for structure dimension design and loading parameter configuration of light-gas launcher.
