Design and optimization of linear electromagnetic launcher system for unmanned air vehicle

Various motor types used in the electromagnetic launcher systems, are single-sided linear induction motor, double-sided linear induction motor, permanent magnet linear synchronous motor and permanent magnet brushless DC motor. In this thesis study, single sided linear induction motor designed for using 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 developed which can be calculated 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 were tested at the launcher design parameters on efficiency, power factor, and weight, which are investigated influence on launching performance. Two-dimensional finite-element analysis evaluates the results from dimension optimization. The results of the software program and simulation results are obtained from comparing with the values obtained from sizing. At last, motor manufacturing drawings were prepared.
