Pressure oscillations that occur when a solid rocket motor is ignited could be reduced by a new propellant formula and optimised monolithic grain design.
The test lasted 22 seconds at a maximum pressure of 110 bars. It will enable experts to check modelled data against observed results from 38 sensors lining the inside of this reusable demonstrator. Nyckelord :
