The device and method include a cylindrical warhead with a cylindrical, central explosive charge and a tubular perforated mask surrounding the explosive charge, and also with at least two ignition devices, the first ignition device arranged in a region of one of the head sides of the cylindrical charge, and the second ignition device arranged in a region around a center of a longitudinal axis of the warhead, and having a splinter-generating casing surrounding the perforated mask. | ||||||
| 62 | Oil Shaped Charge for Deeper Penetration | US14685777 | 2015-04-14 | US20160305751A1 | 2016-10-20 | Zeping Wang |
| An oil shaped charge for deeper penetration includes a case, a quantity of explosive material, and a liner. The case is designed with different inner surface sections, where the step inner surface section creates maximum space for the explosive material so that the explosive material can be effectively placed between the case and the liner. A step conical region of the liner, a step conical inner surface of the case, and an effective placement of the explosive material are able to achieve significantly higher speeds for liner materials flow into the jet, thus creating deeper penetration. | ||||||

| A projectile launching device includes a reactive driver, a flyer housing, a flyer and a compressible buffer member. When detonated, the reactive driver will generate a detonation shock wave. The flyer housing defines a bore. The flyer is disposed in the bore and has a rear surface. The buffer member is interposed between the reactive driver and the flyer. The buffer member has a front surface in direct contact with the rear surface of the flyer. The buffer member is configured and arranged to: receive the detonation shock wave from the reactive driver; modify the detonation shock wave to generate a modified shock wave; and transmit the modified shock wave directly to the flyer to thereby propel the flyer away from the buffer member. | ||||||
| 64 | Fuze shock transfer system | US14537934 | 2014-11-11 | US09347754B1 | 2016-05-24 | Brandon J. Cundiff; John J. Spilotro; Wayne Y. Lee; Kim L. Christianson; Thomas H. Bootes; Jason M. Shire; Jesse T. Waddell |
| A munition has a fuze that is mounted nonparallel to the axis of the munition, for example having a largest extent that is perpendicular to the longitudinal axis of the munition. Shocks from the fuze are transferred through a shock transfer device that is in contact with the fuze, to an initiation device that is also in contact with the shock transfer device. Shocks passing through the shock transfer device to the initiation coupler pass through a relatively narrow neck of the shock transfer device. In the shock transfer device the shock is concentrated and located precisely at the neck, before spreading out again and being transferred to the initiation device. In the initiation device the shock may detonate a high explosive material, which in turn is used to detonate a main explosive of the munition, such as a warhead. | ||||||

An embodiment can have a thickness of the metal liner sufficient to provide a mass necessary to generate a first size diameter aperture in a target material. An embodiment an also provide a combination of the liner thickness and shock interaction point resulting in the jet having an improved length to diameter ratio among other advantages. An embodiment of the invention can also provide other advantages such as an explosive to mass ratio of less than 3 or 2 to 1. | ||||||

| An explosives detonator system for detonating an explosive charge with which it is, in use, arranged in a detonating relationship is provided. On acceptance of a detonation initiating signal having a detonation initiating property, the system initiates and thus detonates the explosive charge. The system includes an initiating device which accepts the detonation initiating signal and initiates and thus detonates the explosive charge. The initiating device is initially in a non-detonation initiating condition, in which it is not capable of accepting the detonation initiating signal. The system also includes a radio frequency identification (RFID) based switching device that detects a switching property of a radio switching signal that is transmitted to the detonator system and switches the initiating device, on detection of the detonation initiating property, to a standby condition in which the initiating device is capable of operatively accepting the detonation initiating signal when it is transmitted thereto. | ||||||

| A shape charge holder includes a platform where all the charges are symmetrically positioned about equidistance from each adjacent charge and about an equal distance from a center point. The center point is generally the centroid of the platform. The holder has an explosive bridge fixture which enables simultaneous detonation of at least three shape charges. The charges are angularly mounted in sockets having holes through the platform. When detonated, each jet formed by the exploding shape charge proceeds to a convergence point located orthogonal to the platform. The holder includes a supporting structure that establishes a standoff distance of the platform/charges from a target. In operation, the explosive fixture is attached to each charge and is filled with an explosive that extends to each charge. The explosive fixture includes a single igniter assuring that when the explosive is detonated, so are the shape charges. | ||||||
