摘要
本文用高速实时全息干涉摄影来研究固体火箭推进剂的燃烧,并获得成功。实验发现了双基推进剂燃烧表面上方高温反应中心的存在和变化规律。平台双基推进剂的高温反应中心数增加,表面温度变化不大,但表面附近气相区温度梯度上升,这些是产生超速燃烧的原因。大量碳片飞离燃烧表面是产生麦撒燃烧的原因。
The combustion of solid rocket-propellant is successfully investigated by means of. high-speed real-time holographic interferometer photography.The high temperature reaction centre above the burning surface of the double base propellants and its variety regulation are found. In the case of catalyzed double base propellant, the number of high temperature reaction centres increases, while the surface temperature is not significantly changed; but the temperature gradient of the gas. zone riear the burning surface is seen to have increases. This is the reason of increased burning rate. The reason of mesa burning is that a great quantity of carbon particles fly from the burning surface.
