Abstract
A contoured configured detonating cord and detonator is incorporated into a ember during manufacture thereof. The member may be a rocket motor which is disposed to be broken into small fragments over inhabited areas subsequent to separation of the motor from the warhead. Separation permits the warhead to fly to the target without excessive drag and fragmenting the motor prevents large pieces from falling on the inhabitants. The detonating cord is contoured to the configuration of the motor to prevent stress risers from occurring and thereby weakening the motor structure.
Claims1
In a rocket having a cylindrical motor casing disposed for detonation during flight thereof, a detonation assembly embedded longitudinally in the cylindrical motor casing of said rocket comprising:
- a. a detonating fuze including a sheath enclosing an explosive, said sheath having curved top and bottom intersecting surfaces and said top surface having a smaller radius of curvature than the bottom surface, so that the contour of the fuze and cylindrical motor is similar;
- and,
- b. a detonator embedded in said motor in abutting end to end relationship with said fuze, said detonator including an explosive charge and a bridgewire for ignition thereof, said detonator having curved top and bottom intersecting surfaces, said top surface having a smaller radius of curvature than the bottom surface, so that the contour of the detonator and cylindrical motor are similar, said detonator disposed for detonating said fuze embedded in said motor whereby said motor is broken into fragments responsive to detonation by said fuze.
