How do grenade launchers work? Why doesn’t an uncooked grenade just come out harmlessly when it is shot?
In: Engineering
Grenade launcher grenades typically have some sort of arming fuse that enables the explosive to detonate after it has left the barrel of the launcher.
From my understanding, the common 40mm grenade uses a fly-wheel which allows the spinning hull of the grenade to generate a certain number of rotations before the impact fuse is lined up to detonate the grenade.
