Design and development of a universal digital gauge to monitor firing pin efficiency in weapon systems employing electrical and percussion mode of firing (Torpedo tubes gun mountschaff lauchers)
Torpedo tubes and gun mounts employ percussion mode of firing for initiating primer explosive. A firing pin is installed in the weapon system which is released to impact the primer. Based on the impact of firing pin on the primer, the prepellant is initiated to drive the projectile. Towards assessing the serviceability of the firing pins, weight of blow is to be measured as part of inspection routines and post Defect rectification.
Towards measuring the weight of blow of the firing pin, it is proposed to develop a digital weight of blow gauge utilising load cells for measuring the impact force of firing pin.
