Abstract : A two-dimensional hydrodynamic code has been used to calculate the free-air blast field about the muzzle and muzzle device (brake) of a 105mm Howitzer. The calculated blast pressure wave as a function of time is presented along with the velocity and pressure fields. Also presented are the pressure and force acting on the baffle as a function of time, as well as the impulse the baffle exerts on the gun. Calculated overpressures and recoil reduction are compared with experimental data. (Author)
