Abstract: To determine the optimum load a laminate member or element is capable of bearing, a three-dimensional progressive analysis is proposed in which the stress and strain states of each ply of the laminate are subjected to failure criteria. If there is failure, new ply stiffness parameters are calculated. Thereafter, the ply is tested with the new parameter until the optimal load is determined. If no failure is detected for a given stress and strain for the ply then the load may be incremented and again applied to the ply, for further testing. Alternatively, the same load may be applied to the ply for a further period of time, until the optimal load is determined and/or the analysis is deemed to be finished.

Abstract: A method for joining sections of densified ceramics, and ceramics to carbon omprising the steps of: placing a preceramic polymer between bodies of the materials to be joined, applying mechanical force thereto, and heating to a temperature sufficient to convert the preceramic polymer to constituents of the materials to be joined thus bonding the materials, and cooling to room temperature.

Abstract: An armor applique for the muzzle end of a gun tube includes a collar which astens onto the gun tube and which has affixed to its annular surface a number of radially extending circumferentially spaced explosive filled rods which will cause deflection premature functioning of and/or damage to an oncoming warhead. The rods are replaceably affixed to the gun tube by bayonet type connectors.

Abstract: An explosive and lightweight container comprising fire-extinguishing and rgy absorbing components. The fire-extinguishing component include an exterior vented plate; a honeycomb element filled with a fire-extinguishing agent; and separated from the vented plate by a membrane to prevent leakage and contamination. The energy absorbing component includes an energy absorbing material; pusher plate; and a honeycomb crush element. In operation, any blast and conflagration are mitigated by energy absorbing material and fire-extinguishing material, respectively.

Abstract: A police baton sidearm having a baton main body and a crosshandle which is ttached in a perpendicular manner to the baton main body at a position longitudinally displaced from the geometric center of the baton main body. The baton main body also houses a recessed trigger ahead of the crosshandle and means for launching a projectile. In order to achieve impact insensitivity a double action only firing mechanism is employed. The baton main body is constructed in two parts to accomodate breech loading and various connection schemes including interrupted and multilead threads on abutting portions of the baton main body. Guide rods or a hinge mechanism may be provided to accomodate one-handed loading. The police baton sidearm may also be equipped with gunsights and a laser pointing device for improving the accuracy of the user's aim.

Abstract: A self-inflatable parawing comprises an airfoil made of a flexible sheet erial and having a plurality of apertures located in the lower, aft surface thereof for admitting inflating air created by the positive air pressure of the air stream flowing over the airfoil. An inflatable support frame is located in the airfoil for providing spanwise stiffness to the airfoil. The support frame is inflated by means of a compressed gas cannister connected through a controllable valve to the support frame.

Abstract: A combination gauge measures (1) the depth of the projectile inside a cantube bore after the projectile has been rammed and seated in the lands and grooves of the rifling of the cannontube and (2) any angular deviation of orientation of the rammed/seated projectile normal to the centerline of the cannontube. A data logger electronically records the measured data and a computer stores and analyzes the data.

Abstract: A method for confinement of a gun propellant during the initial stage of ignition provides the ignition by electrical, pyrotechnic, or laser irradiation means. A liquid and or a solid propellant is placed in a substantially closed chamber. A portion of the propellant in a conduit of the chamber exits from the chamber and is cooled in the exit conduit by a thermoelectric or cryogenic means to a sufficiently low temperature for producing a viscous, glassy, or substantially solidified condition to enhance the propellant containment. An ignition stimulus is then applied. A closure means in the exit conduit selectively varies the amount of flow whereby a relatively high temperature and pressure are reached from the chemical energy release of the propellant. Venting of the formed combustive products is provided through the exit conduit whereby sufficient thermal energy is generated to sustain combustion and to ignite the next stage.

Abstract: An acoustic training device for simulating the effects of a weapon posing omnidirectional threat in a tactical engagement simulation system generates an audible signal of a predetermined frequency and duration once activated. The amplitude of the signal generated corresponds to the kill-zone of the weapon being simulated. The signal may be modulated so as to produce a predetermined number of pulses which are easily distinguished from other noises associated with the tactical exercise.
