Abstract: A system and method for tracked vehicle dynamometer testing. The dynamometer system may be configured as a treadmill electric chassis dynamometer having dual, parallel endless belts positioned as substantially flat surfaces with cleats, i.e., the tracks of a test vehicle and a dynamometer vehicle. The track assemblies of the test vehicle and the dynamometer vehicle are generally vertically, mechanically coupled in close contact with each other via a retention fixture. The testing may be conducted in a climatic chamber to simulate various environmental conditions.

Abstract: The invention describes a wall breaching explosive fragmentation ammunition and further a warhead having means for efficiently penetrating concrete and masonry walls, effectively delivering an explosive fragmentation case payload with minimum structural damage to the ammunition's projectile body. The effective wall breaching is achieved using an ogive-shaped, high strength, light weight boron carbide ceramic nose cone cap disposed adjacent to a tungsten alloy nose insert, at the fore of the ammunition. The projectile body is generally cylindrically shaped, preferably made of steel or aluminum to withstand expected forces in the launch environment. The ogive-shaped nose cone may be secured circumferentially to the projectile body with a rubber O-ring to ensure a tight seal.

Abstract: A low visibility interior armor construction for a door of an automotive icle is removably installed in the vehicle without structural change to the vehicle. The construction has a door panel armor component facing an inboard side of the door and a compressible pad between the inboard side of the door and the armor component. The armor component has hooks by which it hangs on the door. The armor component is tightened to the door by tensionable straps connected between the door and the armor component. The construction also has a plate of window armor alongside the door's window frame and a transparent frame forms a channel about a periphery of the plate. The frame is comprised of continuous polygonal bands forming side walls of the channel. Beds of the channel are recessed between the polygonal bands such that the transparent frame defines a continuous surface facing outboard of the vehicle. A transparent flange connects the door armor component to the transparent frame.

Abstract: The incorporation of a nitrated pentaerythritol additive selected from the ono-, di-, tri-, and tetra-nitrated pentaerythritols into hydrazine is effective in lowering the freezing point of the combination while enhancing the performance of the monopropellant by contributing to the total energy of the monopropellant combination. Hydrazine content varies from about 65 to 95 weight percent while the additive of a nitrated pentaerythritol varies from about 5 to about 25 weight percent. An optional additional additive of methyl alcohol from about 5 to about 20 weight percent can be employed with a corresponding adjustment in weight percent of hydrazine when said additive of methyl alcohol is employed in addition to said additive of said nitrated pentaerythritol.

Abstract: Composite resist structures are described for processing submicron electrc and optical circuits requiring very good pattern resolution between lines because of extremely close spacings between circuit elements. The present invention discloses matrix and layer structures wherein high atomic number (Z) material is used to confine the scattering of the electron beams in the resist. A low Z material is used in combination with a high Z material in the layered configuration to slow down electron velocities without creating a great number of scattered electrons.

Abstract: Controlling the release from a conical ceramic crucible of molten thermite eaction products (generally, iron and alumina) to effect optimum penetration of metallic targets by said molten products through the use of metallic discs which are completely protected on their sides against the molten products, thus forcing these molten products to melt the discs sequentially from top to bottom, resulting in a delay of flow of the molten products from the conical crucible to thus permit the molten iron, heavier than the molten alumina, to substantially unimpededly transfer its heat to the metallic target, the molten iron being more efficient in melting metallic materials than the molten alumina.
