Abstract

A semi-analytical model of the Double Sided Tubular Linear Induction Motor (DSTLIM) is adopted for the optimization of the thrust force of the stages of an ElectroMagnetic Aircraft Launch System (EMALS). The model allows a fast and accurate prediction of all the electromagnetic quantities in the device, including the thrust force, the back-electromotive force, the distribution of the induced current and the average magnetic flux density in the teeth. This provides a basis for the design which has been performed by a novel evolutionary optimization algorithm. By using the semi-analytical formulation, the characterization of the machine is greatly facilitated so allowing a fast evaluation of the cost function and of the design constraints.
