Abstract:

The Thermal Effects Test 5 provides data concerning thermal effects on M107 and XM549 Projectiles which have been rammed into a hot XM199 Cannon. This was accomplished by preheating an XM181 Cannon stub tube which is very similar in configuration to the XM199 as uniformly as possible to selected temperatures in the nominal range 400 - 600F. M-107 and XM549 Projectiles, having been emptied and conditioned to 145F were then rammed into the stub tube. In all, four M107 and four XM549 Projectiles were rammed a total of twenty-one times. Tube temperatures at various points near the bore were monitored by thermocouples likewise, five thermocouples located on the inside wall of the shell simultaneously indicated shell temperatures. This data is intended to be used in determining safe timestemperatures for which the subject shell may be allowed to remain in a hot XM199 Cannon without danger of an in-bore premature.
