Artillery recoil mechanisms provide energy absorption by throttling hydraulic oil through a variable orifice. This orifice is a function of the recoil stroke and is mechanically a fixed system. Variations in hydraulic oil characteristics, maximum applied impulse, and manufacturing tolerances in throttling orifice construction cause non-optimal energy absorption. This report proposes a closed-loop feedback controlled servovalve to optimize energy dissipation regardless of system variables. Possible control algorithms are presented. Recoil mechanism computer simulation using servovalve control prove the variability of this approach. Novel applications of electronic recoil control applied to artillery weapons are also discussed.
