Cutaway model of a French ‘fusee detonateur percutante type H modele 1921’ for usage in the ‘ bombe incendiares de 10kg modele 1927’. Translated ; fuze with detonator model H 1921 for 10 kg incendiary bomb model 1927.

The fuze is brass made with a steel propeller which has a suspension lug to hang the bomb in the bomb rack of the airplane. The firing pin is kept away from the firing cap by six steel balls, placed between the flange of the firing pin and the fuze body. They are held in inward position by the propeller, which is screwed in top of the firing pin.

A slot is machined in the firing pin through which a steel pin and a brass shear wire are placed; the steel locking pin preventing the firing pin from moving upward and falling poit of the fuze body, the brass shear wire from the firing pin moving down into the firing cap.

Upon release, the propeller starts rotating in the airstream, unwinding it from the firing pin. When the propeller falls off, the six steel balls fall away. The firing pin is kept away from the firing cap only by the shear wire. Upon impact, the firing pin is hammered inward, shearing of the brass wire, pushing the firing pin into the firing cap. This will ignite the firing cap (red), which will ignite the detonator, activating the incendiary bomb.
