一、设计和试验 有关燃气舵的设计资料是十分缺乏的,设计工作大部分是依据试验而进行的,是否可行,需通过发动机点火试验才能确定,也就是说,在规定的时间内,燃气舵要经受住发动机排气流的冲刷。 在钨与钼合金系统中,熔点是随钨的含量而改变的。例如:钨钼合金中的钨含量低于42%时,在火焰温度为2893℃的情况下, First, the design and test The design information on the gas rudder is very scarce, most of the design work carried out based on the test, is feasible, to be determined by the engine ignition test, that is, within the specified time, the gas rudder To withstand the erosion of the exhaust flow of the engine. In tungsten and molybdenum alloy systems, the melting point changes with the tungsten content. For example, when the tungsten content in the tungsten-molybdenum alloy is less than 42%, when the flame temperature is 2893 ° C,
