Abstract: Disclosed herein is an environmental charging system for providing energy electrically fused bombs without the need for external charging equipment. The system comprises an electrically fused bomb having conventional existing charging well which charging well is usually centrally located along the longitudinal portion of the bomb. An energizing means, which is adapted to be actuated by slip stream air, is fixed within a charging device which is located within the charging well. The energizing means is designed to pop up out of the charging device as the bomb is released from the aircraft such that in its pop-up position it receives slip-stream air which in turn actuates the device. Means are provided for making electrical contact between the energizing means and the bomb only when the energizing means is in its pop-up position.

Abstract: A fluidic-electronic time fuze for detonating illumination ammunition in a rojectile is described. A ram air driven fluidic generator is used to provide both the time base and power to the electronics of the timing system as well as to sense a second signature for the safing and arming system within the projectile. The electronic circuit of the timing system comprises conventional digital counters and logic circuitry which senses output pulses from the fluidic generator. Thus the accuracy of the time fuze is dependent upon the resonant frequency of the diaphragm within the fluidic generator.
