An analytical study of dynamic loads induced by wind shear is reported In the first portion of the study, the effect of simplifications in the equations of motion on solution accuracy is investigated Pitch-plane wind-shear bending moments on a hypothetical boost-glide vehicle are determined using three methods In the first method the equations used are only partially linearized, and the vehicle follows the programmed trajectory by responding to the thrust vectoring control Varying parameters are functions of computed altitude, computed Mach number, or time as appropriate In the second method linearized perturbation equations are used, and all parameters are considered functions of time based on the nominal no-wind trajectory In the third method quasi-steady pitching and bending are assumed Comparisons of bending moment time histories obtained using each of the three methods are shown Significant errors may occur when the perturbation or quasi-steady equations are used In the second part of the study, the influence of a number of major parameters on wind-shear loads is investigated These include fineness ratio, structural stiffness, mass distribution, pay load lifting area, tail fin area, control law, and initial thrust to weight ratio
