FEASIBILITY STUDY OF ELECTROMAGNETIC AIRCRAFT LAUNCHING SYSTEM (EMALS) BY USING ADVANCE ANALYSIS TOOLS

Abstract

The purpose of this paper is to use the Lorentz force to generate repulsion forces to drive aircraft in a short runway. Other aircraft launching systems like steam catapult, electromagnetic linear motor are going to be less used due to their drawbacks. Lorentz force is used to generate the repulsion in between the rail track which forces the armature in forward direction. For this application, the objective is to pull the large load, such as the aircraft, in a linear motion at a sufficiently high speed, where it can take off easily from a short runway. The approach of electromagnetic aircraft launch system is to the significance for safety and efficiency of aircraft-carrier system. Simulation is carried out by using the analysis software LSDyna.
