Chapel floor

As Chapel bullets , even discoidal bullets were lenticular shaped projectiles referred to a parabola -like trajectory should have to fly over enemy lines away and make it from the back. During the First World War , hand grenades were developed that were similar to a disc and were thrown like this.

The projectiles go back to proposals made by the French artillery officer Frédéric Chapel in the 1880s, but they did not succeed.

Jules Verne mentions this bullet in his novel The Invention of Verderbens (1896) as follows:

"No! the engines, after the manner of Artillery Captain Chapel's discoid projectile, return towards the doomed vessel like an Australian boomerang. "

The M15 discus hand grenade is a grenade with a similar shape, although it was not used as a projectile but rather thrown.
