Abstract: Rolling motion dominates the lateral stability of the aircraft. In order to study the random response of the delta wing’s rolling motion under random excitation, external and parametric excitations are added to a more complex rolling model. The approximate probability density of the system is obtained by the dissipative energy balance method, the amplitude envelope random average method and the energy envelope random average method. The accuracy of the three methods is compared by numerical simulations.

Key words: delta wing aircraft, rolling motion, Gaussian white noise, stochastic average method, FPK equation
