Aeroballistic Performance of the 25mm M910 TPDS-T Range Limited Training Projectile.

摘要

The U.S. Army has developed a 25mm spin-stabilized, sabot-launched, limited-range training projectile for the Bradley Fighting Vehicle M242 Chain Gun. It is designed to be a ballistic match to the service ammunition and is designated the M910 TPDS-T. The acronym stands for 'armor-piercing target-practice - traced.' The specified maximum range of the projectile is 8000 meters. During prototype testing at Fort Bliss, TX, it was determined that the maximum range measured by radar was significantly shorter than had been predicted. Subsequent analysis determined that the projectile had anomalous subsonic aeroballistic performance. Firing tables and range safety data were required to certify the projectile for general use; therefore, extensive aeroballistic tests were ordered to determine the supersonic and subsonic aerodynamic characteristics of the projectile. This report documents the results of those aeroballistic tests.
