New Way to Tame a Rocket Engine

Combustion instabilities can make a rocket engine have a really bad day. High frequency combustion instabilities are periodic oscillations of combustion that occur due to the coupled interaction between unsteady heat release from combustion, acoustic fluctuations within the combustor, and perturbations of the incoming propellant.

These instabilities become […]
