DESIGN OF LINEAR ELECTROMAGNETIC LAUNCHER SYSTEM AND DIMENSION OPTIMIZATION USING EQUIVALENT CIRCUIT MODEL OF LINEAR ELECTROMAGNETIC LAUNCHERS TO IMPROVE LAUNCHING PERFORMANCE

In this study, single side linear induction motor has been designed to use in an electromagnetic launcher system that would be alternative of mechanical launcher system for unmanned aerial vehicle. Design specifications are 8 poles, 3 phases, 380 V, 6 m/s rotor velocity, 5.84 kg payload and 409.55N thrust. It is expected that proposed design presents an alternative to conventional launchers. The purpose of the design is to reduce the cost of launching operation and constitute a mobile launcher system. For this aim, the designed prototype motor parameters and geometric dimension equations are presented in study. The software has been developed which can calculate the motor geometric dimensions analytically. The software uses developed algorithm to get optimum geometric dimensions iteratively. The dimension optimization using equivalent circuit model of linear electromagnetic launchers to improve launching performance. Goal function tested at the launcher design parameters on the efficiency, power factor, and weight, which investigated influence on launching performance. Two-dimensional finite-element analysis evaluates the results from the dimension optimization.
