ABSTRACT:
The setback force of a gun launch environment is used to help arm a projele fuze by shearing a pin which holds a slidable nozzle in a non-operative position. The sheared pin permits the nozzle to move into an operative position adjacent to a heat producing resonance tube. A second arming function is performed when the velocity of the launched projectile causes air to push a spring biased out-of-line detonator into alignment with the heat producing resonance tube. Ram air which is forced into the resonance tube by the high speed of the projectile creates shock waves which generate heat which ignite the detonator.
