Landing on an aircraft carrier is a difficult maneuver involving an aircraft, a moving carrier deck, and a complex arresting system that stops the plane in less than four seconds. Furthermore, modeling of the landing gear is difficult due to the interactions between many complicated, nonlinear subsystems. Capturing these interactions is essential to providing a realistic carrier landing simulation that can be used for pilot training and detailed landing gear design and analysis. SDI Engineering has developed GearSim, a landing gear modeling and simulation software tool, and recently adapted it for carrier landing simulations. This software program contains detailed models of all relevant landing gear subsystems, 6-DOF carrier deck motion, and a model of the aircraft arresting system. This study presents a model of the F-18 aircraft and landing gear and demonstrates the carrier landing simulation capability of GearSim.
