Structural Flexibility and Undercarriage Impact Loads: The Combination of Landing Reactions and Dynamic Stresses

Abstract

The calculation of undercarriage landing reactions and dynamic stresses is discussed, and the merging of the two calculations under certain circumstances is proposed. ? formulation of the combined problem is outlined, and numerical examination of a simple case shows that in some cases the reaction forces are appreciably reduced by the adoption of the combined approach. Finally, a criterion is derived which could be used in the early stages of undercarriage design to predict the elicci of aircraft flexibility.
