Abstract : During the development of the M86 Propelling Charge for the 175mm M437 Projectile, a central core ignition system was adopted. This system utilized perforated paper tubes to channel a flash from a base pad through the length of the propelling charge. The paper tubes occasionally left smoldering residue which was considered hazardous. Accordingly, a rigid polyurethane foam was substituted for the paper and was found to burn completely in the propelling charge. Subsequently, the rigid polyurethane composition was also of interest for use in central core ignition tubes in the XM51E1 Propelling Charge for the 155mm T255 and T258 Howitzers. The propelling charge consisted of M17 Propellant. Compatibility of the propellant with the polyurethane was established. (Author)
