Abstract: An initiation fitting (10) includes a sleeve member (12) having a first end to which a fuse (18) or other initiator is connected and a second end to which an initiating charge (38) is connected for initiating a connected device such as a rocket motor and to hinder the venting of gases from the device through the fitting (10). The sleeve member (10) includes an internal passage (14) extending therethrough and a malleable internal flange (48) which protrudes into the internal passage (14). The internal flange (48) is dimensioned and configured so that when the initiating charge (38) detonates, the internal flange (48) collapses into the internal passage (14) to hinder the flow therethrough of explosive gases from the second end of the fitting.

Abstract: Intersecting judiciously located installed holes at the tip section of the airfoil of an internally cooled axial flow turbine blade for a gas turbine engine communicating with a passage adjacent the pressure side and another passage adjacent the suction side of the airfoil provide a resultant flow that creates an aerodynamic seal that opposes the flow of engine working medium leaking into the clearance between the tip of the airfoil and the surrounding annular shroud or outer air seal. The installed holes are in proximity to the intersection of the tip surface with the airfoil pressure side surface.

Abstract: A seeker device, such as a seeker head, includes a housing for both a first optical assembly and a second optical assembly. In the preferred embodiment, the first optical assembly is an infrared telescope having a fixed, relatively narrow field of view for receiving incoming energy via a first path through an optical opening through the housing. The second optical assembly may be a pivotable mirror that is pivoted to provide a wide field of regard. The incoming energy that impinges the pivotable mirror enters through a second path through the optical opening. The energy from the pivotable mirror is redirected into the infrared telescope. In the preferred embodiment, the redirection is achieved by a dichroic mirror that has a high transmissivity with respect to long wave infrared energy and a high reflectivity with respect to mid wave infrared energy.

Abstract: A gas turbine engine blade includes an airfoil having first and second sides and an internal passage extending longitudinally therebetween for channeling air to cool the airfoil. Respective pluralities of first and second turbulator ribs extend inwardly from at least one of the first and second airfoil sides. Adjacent ones of second ends of the first and second ribs are staggered apart longitudinally and overlap chordally for defining a gap therebetween facing transversely for turning cooling air upon flow through the gap. The gap increases convective heat transfer enhancement for reducing cooling air requirements and improving blade creep life.

Abstract: Fiber-optic cable is wound on a cylindrical bobbin without adhesive and is situated in the vehicle so that the cable, attached to a relatively stationary control computer station, is pulled freely off of the bobbin as the vehicle, such as a missile or torpedo, travels rapidly away from the station. In one embodiment, a propulsion engine is located within the hollow interior of the bobbin and the cable flows outwardly in a helix around the plume of the engine.

Abstract: A safety mechanism for use with a firearm having a hammer wherein the hammer has an elongated, vertically extending recess formed therein, a transfer bar traveling within that elongated recess between an extended position and a retracted position. When the transfer bar is in the extended position, the bar is interposed between the hammer and the firing pin allowing discharge of a cartridge within the chamber. When the transfer bar is in the retracted position, a portion of the recess is exposed. The exposed recess is larger than the portion of the firing pin which protrudes from the receiver. Thus, inadvertent firing is prevented as the hammer cannot contact the firing pin. A transfer bar carrier pin located on the hand assembly initially cooperates with the trigger cam and the transfer bar to elevate the bar into the extended position.

Abstract: The present invention pertains to the aerial deployment of generally planar structures. Typically, these structures are explosive arrays. Such explosive arrays are typically used in standoff minefield clearing and breaching on the ground, at river crossings, on beaches, and in shallow water surf zones adjoining beaches. The invention more specifically involves devices and methods for stably deploying such structures. This stable deployment is achieved by positioning the structure in a dihedral configuration as it moves through the air.

Abstract: A combination lethal/nonlethal firearm device is disclosed wherein a lethal gun, pistol or rifle that conventionally fires solid projectiles in the form of bullets, is conveniently converted to a non lethal defensive weapon by means of a novel attachment of a non lethal canister of dibilating chemical fluid such as tear gas or pepper gas to the barrel of the firearm. The canister is removably attached to the barrel by means of a saddle bracket attached to a trigger guard mounnting clamp, and where the direction of fire of the fluid propellant therein is along the firearm barrel and in the same line of fire as the trajectory of a solid projectile bullet of the firearm. Activation of the chemical dispenser is achieved by means of an activation plunger button adjacent the trigger guard in such manner that a peace officer may choose the better of lethal or non lethal defensive procedures.

Abstract: A projectile includes a mechanism which allows the fin position to be reved after the projectile leaves the launch tube thus allowing the fins to have reversed leading edges, which avoids the costly weight of the one-piece design in the prior art, which is a parasitic weight that will result in a lower velocity, and consequently lower kinetic energy, from the same propellant charge. This mechanism also avoids having extra pieces falling from the muzzle and near the firing team or troops near the gun, and has the advantage of a simple, low-weight deployment mechanism which results in the least aerodynamic resistance after full deployment. The mechanism has at least one small winglet on each reversible fin which generates an aerodynamic lifting force to provide reversal of the fin after the projectile leaves the launch tube. These winglets are positioned and designed to cause the least increase in aerodynamic drag.

Abstract: An interface yoke plate is employed to impart directional control of multiple rocket nozzles. The interface yoke plate is rotated and translated in two orthogonal directions in accordance with steering commands from the missile autopilot and effects control along the yaw, pitch, and roll axes of the missile. One actuator yoke plate translates the interface yoke plate along one axis while another actuator yoke plate translates the interface yoke plate along a second axis. The interface yoke plate may also be rotated by one or both actuator yoke plates, causing a relative twisting of the multiple rocket nozzles and thereby directing their thrust in opposing directions and inducing a roll motion of the missile.
