Abstract
The knowledge of how the propulsive force dynamically behaves is helpful to improve models with accuracy. It is particularly important for high performance aircraft and for flight test activity. For high performance aircraft that have a high power-to-weight ratio, the thrust effects on the aircraft dynamics are of major importance, and must be deeply investigate. Due to risks associate to flight testing, models with improve accuracy must be used to detect unsafe flight conditions a priori. This study deals with these two issues above. Through a dynamic thrust model proposed based on engine’s performance charts, it is intended to validate the expansion of the operational envelope from engine of EMB-314 and verify the model accuracy for transient thrust response for Northrop F-5F. In both cases data from real flight tests are used.
