Electrothermal-Chemical Propulsion and Performance Limits for the 120-mm, M256 Cannon

reportActive / Technical Report | Accession Number: ADA241552 | Open PDF

Abstract:

Electrothermal-chemical ETC propulsion and potential performance for the M256, 120-mm cannon are examined. The upper performance limit for this cannon is about 15 MJ of projectile muzzle energy. The study also indicates that the most effective use of electrical energy in ETC propulsion is pressure profile control. The addition of electrical energy simply to augment the total energy results in a low 20 transfer of energy to the projectile.
