| Abstract: | Ablative property of C/C throat insert has close relations with raw material property and processing.Ablative property simulation test of C/C throat insert can be effectively carried out by means of small-scale test motor.Three ablative test methods for small-scale motors were introduced,and a new test method for quadrate throat insert was emphatically analyzed.Test results show that this method is applicable for ablative properties comparison of various kinds of throat insert material,especially C/C throat insert weaved with radial carbon rod. |
