HM-60 pyrotechnic igniters ignition improvement
other
For the start and ignition equipment (a turbo pump starter and two igiters) of the HM60-Vulcain, the main engine of Ariane 5, Europe's future launcher, special propellants based on ampsaiurr nitrate have been developed. As the ignition of such propellants is more sensitive to the well known igition parameters than most other propellants, a special program was initiated in order to study the effect of these parameters and develop the proper ipition system for the equipment.
The investigated parameters were booster formulation, booster mass flow history, rupture disc pressure and initial temperature. The ignition behaviour of the three devices, having different design characteristics, was compared and analysed. Based on these investigations different ignition systems have been selected for the three devices.
