| Abstract: |
| Traditional engineering design method of igniter is to estimate igniter grain mass by empiric formula. The quality of structure design depends on the experience of designer. In this paper, a general method for design igniter and estimation of mass-flow rate is introduced. The final design can be completed according to mass-flow rate, pressure peak and the corresponding surging-up period. Several experimental methods of igniter are used to investigate the ignition process and some results are presented. The general method can be used to design igniter for SRM successfully. The results demonstrate that the method is feasible and economic for engineering application. |
