Abstract:

Foremost of these requirements is that the sabot must ensure the in- bore operation of the projectile, i.e., it must be able to seal the gun tube against the hot propellant gas. Then, especially for long rod kinetic energy penetrators, the sabot must provide enough support to prevent the subprojectile from being permanently deformed in an undesirable manner during in-bore travel. Also, the sabot must constrain the subprojectile during in-bore travel and then discard in such a manner as to impart a small initial yaw and yaw rate to the subprojectile during launch. These parameters are related to target dispersion and should be reduced as much as possible. Finally, the sabot will generally provide the means for assembly of the full round. Hence, such matters as fin encroachment into the cartridge case and location of crimping grooves so that the assembled round can withstand rough handling should be considered.
