Fecha de publicación: 16/06/1981 Fuente: WIPO "royal booby" A fuel-air explosive weapon launched from a remote distance is used for clearing minefields. A set timing pattern in the operation of the minefield clearance round permits varied range through retarding the length of time that a programed sequence of events occurs at the launch site. Upon flight, the round follows a predetermined pattern in deployment of a parachute, firing cloud detonators and initiation of a burster charge. An extendable probe at the front of the round permits detonation at a predetermined level above ground. The descent by parachute provides a relatively stable launching platform for cloud detonators if they are fired prior to the burster charge detonation for dispersal of the fuel-air cloud.
