鱼雷航深 meaning in English

torpedo running depth

The precondition of establishing mathematics model of torpedo turbine system in design condition is to fulfill the external conditions ( such as torpedo sailing speed and depth etc . ) and inner conditions ( such as turbine power and efficiency etc . ) . after establishing mathematics model of torpedo turbine system in design condition , we compiled simulation program to compute all kinds of inner parameters of turbine engine include engine type , principal layout of turbine , inner structure of turbine and state parameters of gases
首先分析设计工况时涡轮机动力系统，在满足鱼雷动力系统的各项外部条件(如鱼雷航深、航速等)和内部条件(如涡轮机功率、效率，燃烧室压力、温度，转子机械强度等)的前提下，建立起设计工况涡轮发动机的数学模型，编程计算并确定涡轮机内部机械结构和燃气热力学状态各参数。
