Within the System and Technology section of the Future Launchers Preparatory Programme (FLPP), efforts concerning solid propulsion focus on the development of technologies for future motor casings and the investigation of the physics of solid rocket motors, especially pressure oscillations via integrated demonstrators.
The Pressure Oscillation Demonstrator eXperimental (POD-X), is an experimental platform dedicated to the investigation of combustion physics and was test fired in cooperation with CNES in 2014, yielding valuable information into solid propulsion combustion processes.
