The variable thrust pintle motor test system driven by electrical servo was developed and internal ballistic property regulation experiments were carried out. The experimental results show that the pintle axial movement is useful to control internal ballistic property simultaneously and four-level pressure regulation can be achieved. The changes of internal ballistic property delaying to the pintle moment are acceptable in engineering application.
