Analytical Investigation of the Landing Dynamics of a Large Airplane with a Load-Control System in the Main Landing Gear.

Abstract

This paper presents the results of an evaluation of an active load-control landing gear computer program (ACOLAG) for predicting the landing dynamics of airplanes with passive and active main gears. ACOLAG was used in an analytical investigation of the landing dynamics of a large airplane with both passive and active main gears. The results of the evaluation of ACOLAG indicate that the program is valid for predicting the landing dynamics of airplanes with both passive and active main gears. The results of the analytical investigation of the landing dynamics of the large airplane show that the active gear reduces airframe-gear forces and airplane motions following initial impact and has the potential for significant reductions in structural fatigue damage relative to that which occurs with the passive gear.
