The precision of muzzle velocity with electromagnetic launcher is affected by many parameters in the launching proceeding. Five shots have been tested without these parameters, such as initial position, pre-load method, and force. The slide electrical contact performance is good with the tests results. The relative error is about 0.56‰ with new mode B-dot probe. According to the five shots results, the mean velocity is 1853.2 m/s, the relative error is 4‰, and the probable error is about 3.06 m/s. It is sho...
