N2 - An efficient method for including the effect of uncertainty present in the design of aircraft wing structures is presented in this work. By representing each uncertain input parameter as an interval number, the dynamic stresses induced in the wing as the airplane accelerates and decelerates on the runway during take-off and landing are computed by considering the interaction between the landing gear and the flexible airplane structure. In order to obtain a physical insight into the nature of the optimum solution two illustrative examples are considered and intervalbased nonlinear programming techniques are used to find the optimum solution.
