Design Investigation and Application of an Aeroengine Gas Temperature Control System

An engine gas temperature control system is presented in this paper.It has been applied to a supersonic fighter engine successfully.Its characteristics such as good control quality,high reliability and excellent maintainability have been demonstrated in the evaluation flight test throughout flight envelope.Its application can not only decrease the life cycle cost by preventing engines from overheating due to high gas temperature,but also provide carefree handling for the pilot with the result of lightening pilot's workload.
