固体战略导弹发动机绝热层,是发动机上十分重要的一部分,它处在发动机高温燃烧区,要抗住温度在300℃以上时间为70s的高温燃气的猛烈冲刷,绝热层质量稍有不好,就会有烧穿壳体和后盖的危险,造成全弹发射失败,因此绝热层结构质量的好坏,是关系到全弹发射成败的关键因素之一。 Solid strategic missile engine insulation, is a very important part of the engine, it is in the engine combustion zone to high temperature, anti-live in the temperature above 300 ℃ for 70s high-temperature gas fierce erosion, the quality of the insulation layer is not good, on There will be the danger of burning through the shell and the back cover, resulting in the launch of the whole shell failed, so the quality of insulation structure is good or bad, is related to the success or failure of the whole missile launch one of the key factors.
