Aimed at the problems that inter-stage magnetic coupling is weak and rotational torque generation is inefficient in conventional multipole electromagnetic launcher, this paper proposes a Three-Stage Tilted-Pole Sextupole Field Electromagnetic Launcher (3S-TP-SFEL).The parallelogram-section driving coils are used to enhance magnetic field uniformity and dynamically align projectile eddy current paths with magnetic field gradients.Based on Maxwell finite-element,electromagnetic characteristics and dynamic responses are comparatively analyzed by field-circuit coupling methodology between the proposed and conventional configurations.The results demonstrate that the tilted-pole topology optimizes axial-circumference magnetic field interactions, increasing armature rotational speed from 2 125 r/min to 3 000 r/min. Through identifying optimal operational parameters,being at a trigger position of 35 mm and at a torsion angle of 17°,a peak axial velocity reaches 203.26 m/s and rotational speed 16 738.02 r/min.The tilted-pole structure is valid in enhancing multistage magnetic synergy.
