一、问题的提出某型空—空导弹,在工艺定型后的批量生产中,一直存在控制舱斜率 K(?)随燃气工作时间增长而下降的问题。生产厂的试验数据表明,几乎全部产品都存在这一现象,其中半数以上的产品,在燃气工作10～15秒内,平均斜率下降1～2公斤米/度/秒。据试验现场观察,有的产品到了燃气工作的最末 First, the issue raised Some type of air-to-air missiles, in the process of mass production after the stereotypes, there has been control of the tank slope K (?) With the increase in gas working hours and the problem of decline. Test data from manufacturing plants show that this phenomenon occurs in almost all products, with more than half of these products having an average slope drop of 1 to 2 kgm / dm2 for 10 to 15 seconds of gas operation. According to the test site observation, some products to the gas work last
