Pressure Oscillation Demonstrator (POD-Y)

The Pressure Oscillation Demonstrator (POD-Y) used to study the instability of combustion inside a solid rocket motor, P120C, was fired on 5 March 2015, at the French military procurement agency test site in Saint Jean d’Illac, France.

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.
