Abstract
A unified set of governing linear and nonlinear relations are presented, which contain aerodynamic, structural, material and control inclusive contributions. Qualitative analyses are undertaken to determine the influences of the individual terms in the governing dynamic relations of lifting surface panels exposed to inertia, aerodynamic loads and noise. Panel buckling and flutter are considered as well as piezoelectric and aero-servo controls. Nonlinear results are evaluated and compared to linear solutions. Unfortunately the phase relations between the various components of the plate governing relations are sufficiently complicated to prevent analytical sensitivity comparisons. A limited set of numerical simulations are offered instead. Results are applicable to full scale flight vehicles as well as to UAVs and MAVs.
