Abstract

Abstract: To solve the low efficiency of current steam catapults of carrier-based aircraft, the authors proposed the electromagnetic catapult of carrier-based aircraft using double-sided linear induction motor. The authors analyzed the technical requirements of the catapult of carrier-based aircraft through the kinetic equations, analyzed the drive source of the catapult - long primary double-sided linear induction motor - through the physical model and equivalent circuit, derived the relationship between required thrust and the design parameters of the electromagnetic catapult, and provided specific design parameters. Using computer simulation analysis, the authors analyzed the impact of secondary length, motor pole pitch, turns and other design parameters on electromagnetic thrust output, and established the finite element model to verify the validity of theoretical calculation. Through theoretical analysis and simulation, the authors provided a theoretical basis for research for linear induction motor of the catapult of aircraft carrier.
