Abstract:

An experimental test facility has been developed to simulate to a certain degree in a laboratory the loading and thermal environment experienced by gun barrels in automatic weapons. The test facility is capable of pressurizing hollow thick-wall cylinders cyclically at a rate of 550-600 cycles per minute and at pressures of 3500 kgsquare centimeters. The rise time of the pressure pulse is less than 1 millisecond strain rates of about 3second and test temperatures are 260 C, 538 C and 815 C. Temperature is held constant during the test. An automatic air driven hammer is used as the energy source to provide the cyclic loads and a solid loading medium is used to transmit pressures in the specimen. The report discusses the background of the program, the development of the apparatus and the results to date. Author Modified Abstract
