The Main Problems in the Operation of Ramming Devices in Artillery Weapons

The article discusses the principles of operation of loading devices of artillery weapons with a focus on the ramming device as the most important part performing mechanical movement with the round. The attention is focused on hydraulically driven ramming devices, where the possibility of using linear and rotary hydraulic drives is investigated. At the same time, the possibilities of experimental determination of model parameters such as motor damping coefficients, hydraulic resistances, reduced values of compressibility coefficients in the given circuit are presented. The advantages and disadvantages of the used flowmeters are shown for their comparison, from which it is possible to derive the velocity of insertion of round parts. The determined parameters are used for modelling the movement of the rammer and the projectile. Experimental procedures can also be used for the diagnosis and technical control of ramming devices according to national defense standards based on STANAG standards and calculation methods when upgrading existing hydraulically driven loading devices.
