Abstract
The purpose of this paper is to define a method which will allow the calculation of vertical shear and vertical bending moment diagrams using inputs which are commonly available in preliminary design. The scope of the paper is such that not the entire spectrum of aircraft conditions can be evaluated, however, the method will result in the ability to calculate shear and bending along a significant portion of the aircraft length. The method will first be presented as it specifically applies to the V-22 Osprey. Correlation between the method and the V-22 NASTRAN output will be shown. All V-22 data presented in this paper reflects the 1987 Full Scale Development (FSD) aircraft. The method will then be generalized showing the potential application to single rotor or tandem helicopters.
