Abstract:

This report describes an experimental program conducted in support of the US Army Modernization Program. Normal and oblique reflected blast parameters, including peak pressure and impulse, were measured to characterize the explosive output of multiperforated M26E1 propellant. Three sizes of spherical propelllant charges were fired over a reflecting surface on which an array of pressure transducers was used to obtain pressure-time histories at scaled distances. A series of Pentolite tests was also conducted at similar scaled distances to establish a baseline for comparing the reflected blast parameters measured in the propellant experiments. The blast pressure and impulse data obtained showed that at the scaled distances tested the maximum explosive output of M26E1 propellant is comparable to Pentolite.
