Abstract: A laser weapon countermeasure method in which a chemical countermeasure is eployed into the atmosphere along a predetermined length that is located between that which is desired to be protected and a high power laser weapon so as to cause the laser energy emanating from said laser weapon to bloom and be dissipated when the laser energy is directed into the atmosphere containing said chemical countermeasure.

Abstract: A method is disclosed for optimizing the performance of self sustained diarge rear gas halide lasers by using a gas mixture containing two halogen bearing gases. One of these gases is chosen for its attaching properties to optimize the operation of the discharge. The other gas is chosen for its weak attachment and its ability to form the excimer molecule in collisions with rare gas metastables. A representative strongly attaching halogen donor, XHn, is selected from F.sub.2 and NF.sub.3, and a representative nonattaching halogen donor, YHn, which may be weakly attaching, is selected from CH.sub.3 F, CH.sub.2 F.sub.2, and CHF.sub.3. The XHn gas has a concentration value from approximately 0.1 percent up to about 10 percent which is adjusted to maximize the production rate for excited and positively ionized rare gas atoms to yield the excimer state molecules RgHn*, wherein Rg is a rare gas.

Abstract: A rocket motor that has a fast burning propellant therein with a dispenser rrangement for dispensing a fluid chemical suppressant into the exhaust gases of the solid propellant for reducing the flash signature.

Abstract: A laser effects simulator having inner and outer cylinders which serve as parate plenums for two gases--a fuel and an oxidizer. Each plenum contains a multiplicity of small release ports or holes. An inner cylinder serves as a combustion chamber. The inner cylinder contains two sets of small release ports or holes arranged to simultaneously match or line up with the multiplicity of ports in the two plenums. Thus, allowing both fuel and oxidizer to be admitted to the combustion chamber and become mixed. On one end of the inner cylinder is an igniter that starts the combustion process. The reaction creates a high temperature mixture which expands to a low density hot gas that simulates the results that are produced when a high energy laser beam interacts with a solid surface.

Abstract: A multi-warhead, anti-armor missile which includes a missile that has a bter section, a sustainer section, guidance and control means, and primary and secondary warhead sections at nose portions of the missile, with said primary warhead being designed for defeating basic armor of an enemy target and said secondary warheads being designed for dispersal into a cluster prior to the missile arriving at the target and arranged for defeating advanced armor explosive positioned around the basic armor.

Abstract: A method of reducing the visible flash caused from afterburning of a rocket otor by injecting a fire extinguishing suppressant material into the exhaust gases from the rocket motor and injecting the fire extinguishing suppressant material near the exhaust end of the rocket motor nozzle and about an internal periphery of the exhaust nozzle. An effective fire extinguisher suppressant includes fluoro halogenated carbon compounds and specifically CBrF.sub.3.

Abstract: A device in which a solid suppressant is ablated and dispensed into the gs of a main burning rocket motor in which a fast burning smokeless type solid propellant is burning to allow the suppressant to control afterburning of the gases from the burning solid propellant and the suppressant being dispensed by a sustained action igniter pyrotechnic that is also used to ignite the main motor solid propellant.

Abstract: A new mid-infrared laser in hydrogen which produces an output when excited by a high voltage pulse discharge in a long, low loss cavity to produce laser action in three or more lines as output pulses with lengths varying from less than 1 microsecond to over 6 microseconds with wavelengths in the 3 .mu.m band including 3.71 .mu.m, 3.77 .mu.m, and 3.84 .mu.m.

Abstract: A lightweight composite launcher pod which includes a multiplicity of eloted launcher tubes that are accurately aligned in a composite material with the composite material having four outer sides with alignment surfaces on three of the sides and bearing and alignment surfaces on the other side, and the lightweight composite launcher pod being capable of serving as the shipping and storage container for rockets before launching of the rockets as well as for launching the rockets therefrom when mounted in a launcher structure.
