Progress in Civil Tilt-Rotor Handling Qualities

Travellers should expect future transport aircraft to have excellent handling qualities. With the levels of augmentation available from active control, under normal circumstances, no task should require more than minimal pilot workload. Good handling underpins flight safety and validated criteria underpin good handling. This paper reports progress in the development of Handling Qualities criteria for a civil tilt rotor aircraft. The emphasis in the paper is on pitch/flight-path handling, particularly in airplane mode. The large prop-rotors serve to degrade handling, reducing damping and the manoeuvre margin. Current fixed-wing handling criteria, such as bandwidth and CAP, do not adequately pick up these effects and supplementary parameters need to be introduced. Results from piloted simulation trials conducted at Liverpool are presented that confirm the analysis and define the Level 2/3 HQ boundary.
