Abstract
A probability of hit (PHit) methodology has been developed to characterize the overall performance of the C6 General Purpose Machine Gun (GPMG) and 40 mm Automatic Grenade Launcher (AGL) Integrated on a Remote Weapon Station (RWS) Mounted on a Tactical Armoured Patrol Vehicle (TAPV) Platform. The methodology takes into account four (4) different scenarios (static/moving vehicle to engage a static/moving target) to develop an error budget of the weapon system. The error budget analysis breaks down the total dispersion, i.e., the standard deviation (SD) of the impact point position, into four (4) main error sources: weather, gun, projectile and the Fire Control System (FCS) Dispersion. The weather dispersion can be developed to see the individual contributions of the standard deviation of the wind speed, atmospheric temperature and atmospheric pressure. The Gun dispersion can be developed to see the individual contributions to the standard deviation of the gun support and the gun barrel. The projectile dispersion can be developed to see the individual contributions to the standard deviation of the ammunition dispersion, muzzle velocity, drag-mass ratio and tracer effect. The FCS dispersion can be developed to see the individual contributions to the standard deviation of the gun laying, target tracking, vehicle movement and mutual interaction effects. The PRODAS (PROjectile and Design and Analysis System) budget error and simulation package were used to model the weapon system p
