M226 Grenade Launcher with Reinforced Tube.
Abstract
When the M226 Launcher was fired from the M60 tank, short rounds were experienced approximately 23% of the time. It was also observed that cracked launching tubes occurred with short ranges, but the cause of cracking was not known. Time and funding limitations did not permit an investigation to verify the cause of cracking. Analysis of damaged tubes indicated that cracking resulted from overstressing the wall of the launch tube, and that reinforcing this area by wrapping with glass filament-reinforced polyester film tape would solve the problem. Tubes wrapped with the reinforced tape were subjected to a variety of weather conditions and test fired thereafter. All tubes performed satisfactorily and the range requirements were met in all cases. It was concluded that this type of reinforcement should be usable as a retrofit to components already purchased.
