ABSTRACT:
An activation device to initiate functioning of a bomb fuze upon ejection the bomb from an aircraft comprises a tube filled with a fluid or semi-fluid and attached to the skin of the bomb, between the support lugs and beneath the ejection mechanism. One end of the tube is closed and the other end is fitted with a movable piston, with a sensor positioned adjacent to the piston. Upon bomb release, the tube is impacted by the ejection mechanism, displacing the fluid and moving the piston against the sensor. The signal from the sensor initiates fuze action. Piston movement may be utilized in any suitable manner, such as initiating an explosive device, impacting upon a piezoelectric element, or unlocking a mechanical linkage.
