The first hot fire test of the Pressure Oscillation Demonstrator – eXperimental (POD-X) demonstrator took place at the French military procurement agency test site in southwest France on 11 March 2014.
POD-X is an experimental simulator used to measure pressure oscillations in solid rocket boosters for present and future launchers. It incorporates 263 sensors, is 6 m long and 70 cm in diameter and can hold 2700 kg of propellant. Testing can last for 27-30 seconds at a nominal pressure of 65 bars.
