空气动力学研究中心、七机部、科学院、上海8252所等八个单位组成的联合试验组,从80年11月至81年5月,在7013厂先后进行了9次烧蚀/侵蚀试验。 试验在FG-9发动机排气中进行。排气温度约2000°K,排气速度为2500米/秒,排气压力为1.5公斤/厘米~2,排气中Al_2O_3含量为30％(重量百分此),模型为球锥形,R15毫米,半角11°,底部φ60毫米、由试验端头和底座组合而成。试验时端头驻点离喷管出口截面50毫米。测试项目有电影摄影,定时摄影,外形测量,表面辐射温度测量。支架采用非冷却的钢结构。试验结合发动机正常试车进行。试车情况表明:这样的试验对发动机试车没有影响,试验结果见表1。
Aerodynamics Research Center, Seventh Machinery Department, Academy of Sciences, Shanghai 8252 and other eight units of a joint experimental group, from November 80 to May in 81, has conducted a total of 7013 plant ablation / erosion test. The test was performed on the FG-9 engine exhaust. Exhaust temperature of about 2000 ° K, the exhaust speed of 2500 m / s, exhaust pressure of 1.5 kg / cm ~ 2, the exhaust gas content of 30% (weight percent), the model is spherical cone, R15 Mm, half-angle 11 °, the bottom of φ60 mm, by the test end and the base combination. End of the test station end nozzle exit nozzle section 50 mm. Test items are movie photography, time photography, shape measurement, surface temperature measurement of radiation. Bracket with non-cooling steel structure. Test with the normal test engine. Test conditions show that: This test had no effect on the engine test run, the test results in Table 1.
