Abstract:
1. A mortar blast diffuser through which a round is fired, the mortar blast diffuser having a conical outer dimension and an outer surface to mount-instrumentation comprising: at least three substantially similar vanes disposed inside the mortar blast diffuser for directing a flow of gas out an exit orifice of the mortar blast diffuser; at least three internal surfaces located between the at least three substantially similar vanes to form a circular inner dimension that is concentric with the outer dimension of the mortar blast diffuser; and an instrumentation mounting port disposed on the outer surface of the mortar blast diffuser without disturbing gas flow and without contacting the round; wherein when the round enters the diffuser, propellant gas is exhausted with equal pressure reduction along at least three channels formed by the round and the at least three internal surfaces, causing the round to stabilize during its exit out of the exit orifice.
