Abstract: | A prototype of impulse thruster for radial thrust trajectory correction munitions is designed. It adopts semicon-ductor bridge (SCB) as ignition element, Ti/KCIO4 (TK) as ignition charge and ammonium perchlorate/aluminium (NA) or potassium picate/RDX (KR) as main charge. A thrust test device of impulse thruster is also designed. The output per-formance of the impulse thruster prototype is tested by the device. The tested results show that it can meet the safety re-quirements of 1A1W/5 min no-fire level and produce 0.2-0.6N·s thrust impulse within 3ms of action time under certain test conditions;the corresponding ignition delay time is less than 0.5 ms. |
