Preliminary Validation of the Wind Tunnel Based Flight Control System Evaluation Method
MATEC Web of Conferences, 2018 As mathematical models of aircraft aerodynamics and rudder loadings always have to be built in the hardware-in-the-loop simulation, wind tunnel based flight control system (FCS) evaluation methods were proposed in order to test and evaluate the flight ...
