采用冲压发动机地面连管试验系统对玻璃纤维酚醛材料进行了烧蚀试验.通过分析烧蚀材料的微观形貌以及燃气温度、压力和流速对烧蚀过程的影响
研究了玻璃珠的形成机理.研究发现:在补燃室不同位置
玻璃珠呈不同分布;玻璃成珠过程受燃气的压力、温度和速度的共同作用
燃气流速对玻璃珠的形成影响最大;从保护碳层、减少烧蚀的角度
玻璃珠的形成对材料烧蚀是不利的
应抑制液态层形成玻璃珠.
An ablating test was conducted on glass fiber reinforced phenolic ablator by using the ramjet experiment system.The ablation morphologies of the phenolic ablator reinforced by fiberglass was observed
the forming of bead and the influence of gas-fired temperature
pressure and velocity of flow was analyzed.The results illustrated that the glass beads were unevenly distributed in the combustor.The glass bead was formed by the combined action of gas pressure
temperature and velocity
in which the velocity influenced the process most.In protecting char layer and reducing erosion
the glass bead formation from liquid layer is expected to be technically restrained.
