Therefore the mathematical-and-physical model of the process was deduced. Principle tests of emergency gas jet blowing-off process, which is the small-scale-model of emergency blowing system with gas generator for submerged vehicle, were carried out, which simulated the drainage regularity and the major performance parameters of emergency gas jet blowing-off process while at 100m depth underwater, and the influential factors which impact on the efficiency were investigated. The simulation results of the model was compared with the experimental results, and it was suggested that the model of the process which developed by thermodynamics methods for engineering calculating is accord with the factual experiments situation and can provides significant basis for the designing and applying of the emergency blowing system with gas generator for submerged vehicles.
