LAUNCHER, ROCKET, MULTIPLE, 4.5 IN. T106E1 - LAUNCHER HEATING STUDY
Abstract
Various all-plastic rocket launcher tubes which had previously undergone partial firing tests were subjected to outdoor weathering for 8 months and were further tested under actual firing conditions. It was found that this exposure did not adversely affect the bursting or delamination resistance of the tubes but that a tube equipped with firing rails became useless after five rounds following the exposure period. It was not known whether the failure was induced by the outdoor exposure or whether the fatigue limit of the metal rivets holding the firing rails had been nearly reached in previous firing tests. The initial and interim development of plastic launcher tubes capable of withstanding the firing of 100 rounds was reported in Picatinny Arsenal Technical Reports Nos. 1704 and 1763. A reinforced plastic protective front end ring was developed which withstood twenty rounds and which on examination appeared that it would be satisfactory for many more rounds. Two woven steel blast mat specimens, one impregnated with rubber withstood 10 firings and with modifications this construction might be developed into a satisfactory blast mat. All-plastic launcher tubes which do not become seriously hot and which withstand firing for 100 rounds and are unaffected by outdoor exposure have been developed.
