Analytical Simulation of Landing Gear Dynamics for Aircraft Design and Analysis 710401

This paper presents an analysis of a nonlinear landing gear mounted on a flexible airplane equipped with external stores and tip tanks. Interaction effects of the flexible airplane with the gear are included. The method of treating the strut lockup-breakout phenomena is an improvement over previous work. Test results are presented from a full scale test of an airplane supported on displacement controlled hydraulic actuators, which simulated taxiing over discrete runway bumps. The analytical method was applied to several design problems which are also discussed.
