Abstract: A storage and planting rack for an actuation mine simulator, having a recgular frame enclosing an open central volume, guiding channels for orienting the mine simulator, and latching and tripping mechanisms for controlling release of the mine simulator. Fins on the mine simulator are guided by diagonally opposed channels into the storage and planting rack. An electro mechanical member causes release of the mine simulator in response to an electric signal, thereby enabling planting crews to precisely control the planting location of each mine simulator.

Abstract: An ignitor for a liquid propellant gun having a center electrode supported nd surrounded by insulation so that only a planar or domed face is exposed. The assembly is firmly seated in the bolt nose of the gun and several outer electrode configurations with little or no precombustion area are disclosed.

Abstract: A safety-arming device for use in a highly maneuverable missile is disclo which takes into account lateral acceleration of the missile and selects the proper point in the trajectory after which arming of the missile warhead may safely proceed. The safety-arming device uses a series of electrical, mechanical, and electromechanical interlocks to insure that premature arming of the missile warhead does not occur.

Abstract: An ordnance item casing construction which enables case venting and contred combustion of high energy fuel contained within the casing when the ordnance item is exposed to a high temperature environment. This casing construction utilizes a perforated thermally insulating composite doubler and series of thermally conductive plugs aligned with cavities in the casing wall, and applied to the exterior of the ordnance item. Heat from the high temperature environment is conducted by the plugs to the casing wall.Local ignition and combustion of high energy fuel within the casing rapidly burns through the wall at regions of reduced wall thickness caused by presence of the cavities. The interior of the casing is thereby vented, and catastrophic pressure buildup within the casing is prevented.

Abstract: An aircraft for making vertical and short field takeoffs is powered by a ass turbofan engine having a core turbojet and a bypass fan. For vertical takeoffs, the efflux from the bypass fan is deflected downward to create lift. Exhaust from the core turbojet is ducted to turbine driven lifting fans at remote locations to create supplemental lifting forces which also provide aircraft control and stability. For cruise, the bypass fan efflux is discharged aft until sufficient forward airspeed is attained that exhaust gas flow to the lifting fans may be shut off, and exhaust gas flow may also be discharged aft.

Abstract: Aluminum particles are coated with a composition containing 84 .+-. 3 wei percent desensitizing wax, 2 .+-. 0.5 weight percent lecithin and 14 .+-. 1 weight percent nitrocellulose prior to being mixed with other ingredients of an explosive composition in a bomb manufacturing process in order to eliminate the possibility of dust explosions occurring during the bomb manufacturing process.

Abstract: Methods for controlling the sizes and shapes of fragments produced by ward casings are disclosed.
