The pressure in the typical crack of simulative motor was studied by test in order to analyze the effects of pressurization rate, crack-gap depth and crack orientation on the crack tip pressure, crack inlet pressure and chamber pressure. The result indicates the crack orientation has little effect on the pressure in the crack; the maximum pressure in crack tip and the pressure rate between crack tip pressure and chamber pressure increases with an increase in pressurization rate and the depth of crack.
Key words： simulative motor; crack; ignition
