Testing of a flight envelope protection system for fly-by-wire aerial vehicles

Akmenek, Bulut Efe
Aircraft should remain in their flight envelope during their operation. Monitoring these limits while coping with other mission related tasks increase the pilot workload substantially. In this thesis, envelope protection methods and tactile cues are investigated for pilot workload reduction and their effectiveness compared to both conventional methods and each other. For this purpose, a simulator environment centered around an active inceptor is established such that both rotary and fixed-wing configurations are possible. With the Direct Adaptive Limit Margin Estimation method envelope boundaries are estimated. Different tactile cueing methods are developed. Via the active inceptor, cueing of the estimated limits with developed methods are tested in both piloted and pilotless simulations. Pilot reviews for tested cueing methods are scaled with the NASA-TLX method and compared with each other.
