Abstract : The system of the present invention basically consists of a detector unit mounted in each bomb or airborne weapon and operable upon interception of a signal emitted by an aircraft-mounted source. The required signal for arming is present only in a well defined zone below the aircraft and only in response to pilot command during weapon release. The signal consists of an unmodulated beam of high-energy photons (gamma rays) emitted by a radioisotope source on the aircraft. The weapon must fall well below the aircraft to see the signal. Geiger-Mueller tubes are used for radiation detectors and the resulting signal is processed to initiate the arming or fusing sequence. Power for the operation of the detector and associated electronics is transferred through the metallic covering of the weapon by means of a split-core transformer at the time of release.
