A coupled model of aeroelasticity and flight dynamics for high-altitude, long-endurance (HALE) aircraft is under development based on the geometrically exact, fully intrinsic beam theory, ONERA aerodynamic stall model, and six degrees of freedom model of rigid body motion. The correlation among the present model, MSC/Nastran, UM/NAST, and NATASHA was studied, including the cases of static equilibrium...
For the issue of determination of flight range of controlled aircraft, under the condition of given constrained control, linear differential movement equations of aircraft are chosen and solved in a comparatively short time to determine the flight range based on maximum principle in modern optimizing control theory. The example illustrates that calculation accuracy is high, and the proposed method...
