Unstart Phenomena

Unstart Phenomena is a transient aerodynamic instability in scramjet propulsion systems characterized by the sudden detachment and upstream propagation of a shock train caused by adverse pressure gradients, leading to the collapse of supersonic airflow within the combustor and a subsequent loss of thrust generation.
