T-6A Texan II In-Flight Simulation and Variable Stability System Design
Germann, Kenneth Paul
In-flight variable stability aircraft and in-flight 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 in-flight 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 response-feedback 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 in-flight simulation, it is shown that the same configuration is useful in handling qualities training of military test pilots.
