The present invention is directed towards an explosives detection system for an aircraft, and more particularly to an explosives detection system which continuously tests the internal passenger compartment of an aircraft for the presence of gases which are emitted from explosives such as dynamite, TNT, plastic explosives, and the like.
An exceedingly dangerous and growing problem in air travel is terrorist activity. All too often, such terrorists smuggle bombs on board commercial airliners and threaten to explode them unless the terrorists' demands are met. This criminal activity endangers the lives of the passengers on board the aircraft and sometimes results in loss of life. A number of attempts have been made to prevent this criminal activity and its abhorrent effects. Dogs have been specially trained to identify and sniff for the presence of explosives and, in a number of cases, have been successful in preventing terrorists with explosives from boarding a plane. Specially-designed explosives detectors which are commercially available can detect the presence of explosives.
An explosives detection system on board an aircraft which has a plurality of explosives detectors to sample the environment of the interior passenger compartment of the aircraft to detect the presence of explosives. The detection system includes an electronic circuit connected to the explosives detectors which provides an electronic signal which indicates the presence of explosives on board the aircraft upon one of the explosives detectors sensing the presence of explosives.
In another aspect, the invention is directed towards a detection system which also includes a plurality of air fans positioned to cause air to be directed towards the explosives detectors and includes an electronic circuit connected to the explosives detectors to provide a first electronic signal which preliminarily indicates the presence of explosives on board the aircraft. This electronic signal also causes the rotational speed of the fans to be increased in order to provide an increased air flow to the explosives detectors. The electronic circuit also provides a second electronic signal which confirms the presence of explosives on board the aircraft.
In a further aspect, the invention is directed towards an explosives detection system which includes an electronic circuit which periodically samples the outputs of the explosives detectors on a multiplexed basis.
In still another aspect, the invention is directed towards an explosives detection system which includes an electronic circuit connected to the explosives detectors which provides a first electronic signal upon the output of one of the explosives detectors satisfying a first predetermined threshold and a second electronic signal upon the output of the explosives detector satisfying a second predetermined threshold.
