Simulation of flexible aircraft using real time aerodynamic calculations.

The model was successfully implemented for a DHC-6 Twin Otter aircraft. Deviation from the base rigid model increased proportionally with pilot input frequency and duration. The magnitude of the deviation from the rigid model produced with the real time flexible model was twice that of the linearized flexible model.This study investigates a new method for modeling and simulating flexible aircraft. The method determines the aerodynamic forces and moments in real time, utilizing a 2-D aerodynamic strip theory. It includes non-linear effects in the analysis, and can be expanded to incorporate a more complex aerodynamic analysis.This method required no additional computational time, and was able to produce accurate results at a rate greater than 60 Hz (required for pilot in the loop simulations). The real time model represents a higher accuracy simulation at a minimal computational cost. It also provides a framework for more advanced solvers and techniques.
