Abstract

Abstract

In order to guarantee the high performance and efficiency of open loop thermal cycle underwater turbine engine system, the operation behaviour of system working in the condition of variable depth and speed was analysed, the gas speed of nozzle was calculated, the output moment of turbine engine was studied, a dynamics mathematics model being fit for system optimization and new controller design was built, close algebra equations composed by system rotation rate, voyage body speed, combustor pressure, voyage body depth, propellant wastage and pressure rate were gotten by using the stabilization behaviour of the mathematics model. All the design parameters of power system can be optimized by taking pressure rate as key parameter and taking maximal variable speed combination voyage as optimizing target. Applied result of the model shows that the efficiency of power system is improved over 8 %/0. 3 figs, 6 refs.
