| Abstract: | Investigated charring erosive characters of internal insulation of solid rocket motor under flight acceleration. Performed the ablation tests of NBR and EPDM insulation on rotating test system using erosive motor. When acceleration is 70g, pressure is 5 MPa, time is 10s,the flight enhancement factor of insulation is less than 1 7. The experiment result can use to internal insulation design of solid rocket motor. |
