Shipboard Aircraft Arresting System Modeling and Simulation

Shipboard arresting gear is a special aero-carrier unit that is designed to provide an efficient arrestment of the deck jet-fighters of masses 15-25 tons with landing velocities between 180 and 240 km/h. In the current paper, a full-scale arresting system model is created. Main elements of the arresting system consist of cables and hydraulic system. The model contains all basic elements of the real prototype and is employed to analyze the dynamic behavior of the arresting gear with different scenarios. The stroke of cam is enlarged to increase the capacity of arresting gear. The finite element methodology is employed to analyze the dynamic behavior of cables. The developed model is used to obtain parameters of the arresting process - fighter displacement, velocity, acceleration vs. time, as well as pressure in the hydraulic system and tensile force in the cable.
