Title: Study on Projectile Muzzle Velocity Measurement Based on Rotational Speed
Abstract: A method for the muzzle velocity measurement utilizing the rotational speed was put forward.The earth magnetic field sensor and test circuit were installed in bullet or fuse.When the projectile rotates,the coil in the sensor would cut the earth magnetic line and periodically produce inductive electromotive force.Then,the test circuit acquired the signal and saved it in the memory device.After reclaiming the circuit,the data could be obtained from the memory and the muzzle rotational speed could be known.According to the twist pitch of rifling,the projectile's muzzle velocity could be found out.The method was verified by using live ammunition test.
