New Method of Attenuating Landing Impact Force on Carrier-based Aircraft Landing Gear

The conception of landing area is introduced to the aircraft carrier, and a simplified model of the conventional oleo-pneumatic landing gear during the process of landing impact on the landing area is established. The mathematic model is also derived. The dynamic response of the landing gear landing vertically is calculated via Runge-Kutta procedure. Simulation results for both the original model and the new model are presented to illustrate the effectiveness of the new model. The result shows that the maximum of the impact loads on airframe and the maximal ground reaction force are reduced 37.3% and 37.2% respectively.
