A new type of hardware-in-loop test-bed system for underwater heat engine propeller stepless speed changing system was proposed. The configurations of stepless speed changing technique, functions and features of the test-bed system were introduced. A result of hardware-in-loop experiment was analysed. By use of the hardware-in-loop simulation system for underwater heat engine propeller stepless speed changing system, motions of the autonomous underwater vehicle, such as vehicle＇s autopilots （depth / gesture）, can be compensated easily, which has made that momentarily variational signal can be catched by the vehicle＇s speed; The combustion chamber has no over pressure intensity modulation, which has guaranteed the system security; Also it made the system potential to be full display by making good use of the restriction relations between the navigation speed and depth; Underwater heat engine propeller stepless speed changing is taken to real. The experiments show that the performance of the proposed hardware-in-loop simulation system for underwater heat engine propeller stepless speed changing is advanced. The expected goal of the system is reached.
