Research on spin reduction mechanism of the projectile sliding belt in bore

Abstract The sliding belt assembly plays a key role in spin reduction to protect the electronic components and smoothly control projectile posture. complete guided motion bore was reproduced by LS-DYNA software, where gunpowder pressure loaded on bottom. dynamic parameters of obtained simulation agree well with test, including axial velocity, acceleration rotation speed. Great occurs assembly, which is indicated speed projectile, respectively. From interaction at typical times, it escaping from bases periodically ring so that greatly body achieved.
