Investigations were carried out using dynamic modelling techniques. This method builds a data model of the aircraft representing, as accurately as possible, both the aerodynamic characteristics and the structural characteristics to enable “simulations” to be performed. These simulations can be in the form of simply establishing the correct combinations of pilot controls to enable the aircraft to remain at a point in space, through to full dynamic response models whereby the aircraft is “flown” to establish its behaviour.
By using these different simulations, it is possible to understand the nature of the aircraft and its stability characteristics as well as how easy/difficult it may be to control the aircraft during flight. The end goal is to ensure that the aircraft will remain airborne with sufficient controllability to satisfy the design requirements of the mission
