Rifle grenade

mudge
OK...all youse infantry types.
How did a rifle grenade work. I know how it was launched and all, but what made it explode? Fuse? Contact?
I don't mean the type that was just a "pineapple" that clamped on the end of an adapter. I know how that worked. I mean the big M11 type.

Mudge the curious

    hot gases are redirected to the projectile to get it to where its going instead of cycling the bolt. hot gases igite a burn fuse inside the rocket as it flies thru the air. by the time it gets there, its time to go boom.

    Sorry to be a nitpicker, but a rifle grenade and a rocket are two different things. To launch a rifle grenade, most nations use a special grenade-launching blank (whereas the common blanks used for simulated rifle fire have a very fast-burning powder to make the "bang" in the absence of a bullet, the G/L blank uses a totally different charge to launch the pound-plus grenade without stressing the rifle's action or prematurely detonating the warhead). The grenade is simply a huge explosive projectile without its own propellant (some types of rifle grenades had optional booster cartridges to extend range, but the booster was only supplemental to the main G/L cartridge).
    The warheads on some rifle grenades are designed to explode on impact, with the detonator either in the nose or at the base of the explosive charge. The detonators can be piezo-electric or mechanical types. Other rifle grenades use a time fuse, which can be initiated by the hot propellant gas or by the set-back of a release upon firing.
