【摘要】 为评估三向碳/碳材料的烧蚀性能,在北京空气动力研究所研制的FD—04F电弧加热器上对三向碳/碳材料进行了滑行试验,测出了三向碳/碳材料的转捩压力。试验结果表明:滑行试验在测量转捩压力方面是有效的,并给出了三向碳/碳模型的转捩压力数据和最终外形形状。更多还原

【Abstract】 In order to evaluate the 3D C/C material ablating performance, ramp tests are performed with FD-4F arc-heater in Beijing Institute of Aerodynamics, and transition pressure of the 3D C/C material is determined. The test results show that ramp test is effective for measuring the transition pressure. Transition pressure and final shape of 3D C/C material are given in this paper.更多还原
