Air turbine is the power unit of the hydraulic balanced torpedo launch system which is the most advanced launch system in active service.In order to evaluate the performance of the air turbine,models of the start process for air turbine and supporting system are modeled on the basis of theories of thermodynamics and aerodynamics,the simulation software is developed,and the simulation results are analyzed.The simulation results show that the startup performance of the air turbine can match the air turbine pump torpedo launch system.These models not only can be a theoretical basis in the process of designing and manufacturing this launch system,but also can be used to analyze the operation principles of the air turbine pump torpedo launch system.
