前体长度 meaning in English

forebody length

The design point of the designed forebody / inlet is flight mach number m = 6 and flight attitude h = 25km . the three - ramp , mixed external and internal compression hypersonic / inlet is chosen as representative geometry to be designed . nine types of hypersonic / inlet model with difference forebody length and total turning angle are obtained that the incidence angle of the first ramp and height of isolator are given
根据飞行任务要求，以飞行马赫数6 ，飞行高度25km为设计点，给定前体预压缩角、隔离段高度，对具有不同前体长度和不同总压缩转角的带隔离段的前体进气道进行了设计。
With account for the effect of temperature and shock - boundary layer interaction , the forebody / inlet with plane lip and wedge lip are designed by using the design methods of constant shock wave intensity and constant shock wave angle . in the design , the incidence angle of the first ramp , height of isolator , length of forebody and total turning angle of the designed forebody / inlet models are given
另外，根据优选结果，给定前体长度、前体预压缩楔角、总压缩转角及隔离段高度，分别用等激波强度和等激波角度的方法设计了唇口平直和唇口带楔角的前体进气道。
