Proof & Experimental Establishment (PXE), Chandipur, has designed and
developed a Power Ramming System for 155/130 mm Up Gun. Ramming is the process
in which prior to firing, a projectile is positioned in the shot seating
position of a gun chamber. In the conventional method, the projectile is pushed
manually from the back with the help of a wooden rammer rod. This process cannot
ensure identical and quantifiable ramming force for each round in a series.
Variation in ramming force can introduce random variations in internal ballistic
performance of ammunition.
The newly developed system permanently mounted on the trail of the gun overcomes
all the shortcomings of manual ramming. It occupies very less space, ensures
uniform ramming force for all the rounds and is a great boon to the gunners.
There is a provision in the system to increase or decrease the ramming force by
varying the air pressure that drives the mechanical rammer.
