How do grenade launchers work? Why doesn’t an uncooked grenade just come out harmlessly when it is shot?
In: Engineering
A grenade launcher doesn’t use an hand grenade, it’s specialized greande with a propulsion charge. It’s basically like a gun, you press the trigger which hit a percussion cap, this will ignite a propellant at the back of the grenade, just like with a bullet. But instead of pushing a bullet out of a long barrel, it propulse a large grenade out of small tube. This mean that the grenade is going at a relatively slow speed and its trajectory will do an arc to the target. Usually there is a system inside the grenade that arm it after it travelled a certain distance to make sure you don’t kill yourself with it.
