T-6A Texan II In-Flight Simulation and Variable Stability System Design

Inlight variable stability aircraft and inlight simulation are described. The uses of these vehicles and the associated requirements are described. Several forms of control architecture are identified for use in a T-6A inlight simulator. A non-linear model of the T-6A Texan II is developed for use in MATLAB/SIMULINK®. This model is used to design a feedforward responseeedback controller, based on simplified dynamic inversion. This controller is shown to exercise precise control over the T-6A host aircraft dynamics. This architecture is then used to demonstrate simulation of the A-4 and the F-15 by the T-6A. In addition to proving simplified dynamic inversion for inlight simulation, it is shown that the same configuration is useful in handling qualities training of military test pilots
