摘　　要：鱼雷在变速或者变深航行时,效率会变得很低,乃至不能正常运行。所以必须进行变工况的计算,并研究出与之相适应的调节方法。本文应用工程热力学及空气动力学的有关理论,分析了鱼雷燃气涡轮机在变工况条件下的可调参数,提出了可行性调节方法,并给出了相关的计算数学模型。仿真结果验证了数学模型的正确性。As the torpedo runs at variable-speed and variable-range,the engine efficiency will become so low that it sometimes cannot work normally.As a result,off-design conditions have to be calculated and the regulating method is to be put forth accordingly.Using engineering thermodynamics and aerodynamics theories,adjustable parameters of torpedo gas turbine under off-design conditions are analyzed,feasible regulating method is made and relative mathematic model is established.The mathematic model is validated by the simulation result.
