Abstract: An arming wire extractor controlled tension device for an aircraft delive weapon comprising a controlled tension device which comprises a coil of wound wire with a straight end that is pulled through an orifice that allows the application of a force for extracting the arming wire such that it yields a relatively constant force and the angle of pull through the orifice is not a significant variable in firing.

Abstract: A detonation system for explosive rounds, such as a fuel air explosive, is made by providing a sealed launch tube detonator assembly arrangement. The cloud detonator provides for a booster charge which is attached to a pyro delay detonator. The pyro delay detonator permits the booster charge to be hurled a discrete distance into the fuel air cloud to insure proper cloud detonator position while at the same time waiting an appropriate time interval to permit complete cloud formation. The detonator assembly is self-sealing in its launch tube to prevent gases, which hurl the detonator assembly out of the launch tube, from burning the fuel air cloud. The cloud detonator assembly itself contains unique safety features which will prevent premature partial burning of booster charge.

Abstract: A self-erecting structure, including a plurality of unexpanded convoluted bellows means joined together to define an enclosed ring having an interior closed path, along with means for expanding the path. The means for expanding the path include a quantity of propellant contained within the interior closed path in an amount capable of expanding the plurality of bellows to significantly increase the size of the ring upon ignition of the propellant and ignition means for igniting the propellant upon receipt of a command.
