Abstract : A relatively simple mathematical model, and computer program, has been developed for the purposes of estimating the instantaneous pressure distribution, momentum transfer, and braking force, experienced at the surface of a muzzle brake element exposed to the gas flow emanating from the muzzle of a gun tube. The flow field model is established by assuming the existence of quasi-steady flow conditions, and superposing a constant longitudinal velocity component upon the radial gas velocity as defined by the cylindrical blast wave solution of Sakurai. The flow field model is combined with Newtonian impact theory to obtain the instantaneous pressure distribution. (Modified author abstract)
