Throw-Off of Projectile at Muzzle.

摘要

Several analyses of the yawing motion of projectiles in the gun and/or during exit from the gun muzzle are examined for their underlying assumptions and the results are discussed. Results of simple, one-dimensional computations at the muzzle are presented parametrically for the muzzle exit conditions of 155 mm projectile M483 and its modifications at zone 4. The results for the basic design are compared with an approximate two-dimensional solution. (Author)
