This report presents a theoretical study of the behavior of the conventional type of oleo-pneumatic landing gear during the process of landing impact. The basic analysis is presented in a general form and treats the motions of the landing gear prior to and subsequent to the beginning of shock-strut deflection. The applicability of the analysis to actual landing gears has been investigated for the particular case of a vertical landing gear in the absence of drag loads by comparing calculated results with experimental drop-test data for impacts with and without tire bottoming. The calculated behavior of the landing gear was found to be in good agreement with the drop-test data.read more

Oleopneumatic shock strut dynamic analysis and its real-time simulation
TL;DR: An analog simulation representing dynamic shock absorption characteristics of a conventional oleopneumatic landing gear strut has been developed and provides an important design tool for optimizing pin profile, as well as evaluating existing shock strut designs.
