Abstract
This disclosure relates to a system for actively controlling shock train in a high speed, air-breathing propulsion engine. The system includes an isolator, a sensor associated with the isolator, and a shock train fuel injector in electrical communication with the sensor. The sensor is configured to sense changes in pressure generated by a shock train in the isolator. The shock train fuel injector is in electrical communication with the sensor. The shock train fuel injector is configured to modulate fuel flow to the engine to control back pressure produced by the engine in response to predetermined pressure changes in the shock train.
