The anti-jamming ability of igniter depends on the charge in the igniter. The combustion of the igniter charged with barium nitrate and those charged with magnesium powder and PTFE is stable, while the igniter charged with zirconium hydride and lead oxide is unstable. The standard error of duration of the third kind of igniter flame is 523 ms ,and also its nozzle hole is blocked seriously.
