Magnetoflyer method for measuring gas-gun projectile velocities

Abstract

The magnetoflyer method has been developed as a convenient and fiducial technique for measuring projectile velocities from propellent and gas guns. The velocity is estimated from the time interval between two electromotive force signals when the projectile, which includes a small ferrite magnet, passes through two pick-up coils. It was confirmed that the method was available up to 5 mm/μs.
