A system for neutralizing a buried mine includes a laser that is configured to generate laser energy that communicates through the covering ground material and accesses the mine in a manner sufficient to neutralize the mine. Neutralization can occur by deflagration or detonation. The laser includes a solid-state lasing medium that is run substantially uncooled during the lasing run. Namely, the lasing medium is operated without cooling until the lasing medium reaches a temperature where thermal population in a lower laser level begins to significantly lower inversion density. Following completion of the lasing run, the lasing medium is cooled at a rate limited only by a thermal stress fracture level of the lasing medium. Operation of the laser in this manner permits the laser to deliver high-irradiance, high-repetition rate pulses according to a burst mode operation that successfully accomplishes neutralization in a desired time period. The burst mode also facilitates preferential selection of the mechanism of laser energy-material interaction to promote rapid penetration rates.

A method for deflecting a projectile from an initial trajectory. Such a projectile has a first surface area and a second surface area and moves through a gaseous atmosphere with a surrounding plasma sheath. This method includes the step of directing electromagnetic radiation toward the projectile, wherein the electromagnetic radiation has a wavelength which is absorbed by the plasma sheath but is not substantially absorbed by the gaseous atmosphere.

The Synchronized Photo-pulse Detonation (SPD) method employs several fundamental techniques that are able to dramatically improve the kill-ratio of Laser Supported Detonation (LSD) of hostile targets, such as: missiles, aircraft, ships, and other land based targets, all the while reducing the chemical energy consumption and time needed per kill by thousands of times, thus making its deployment cost effective. The SPD to use 2 (two) synchronized laser pulses to create a Laser Supported Detonation Wave (LSDW) in a mixture of target vapors and atmospheric air. The first pulse creates an ignition plasma spark (in a mixture of air and target vapors), while the second (higher powered) pulse serves to create and support a shock wave from the heated plasma. This shock wave heats the surrounding air layer (mixture of air and target vapors) so that it begins to absorb the laser beam and to create from itself the next plasma layer with the formation of a new shock wave. The several thousands of tons of force generated by the LSDW are more than capable of destroying any object, such as an ICBM, aircraft, or build.

A system and method for automatic weapon allocation and scheduling of the present invention. The inventive method includes the steps of providing data with respect to threats, weapons, weapon allocation options; weapon allocation rules; and temporally dependent constraints with respect thereto; evaluating the data; and temporally allocating the weapons to the threats automatically in accordance with the evaluation. The invention computes the optimal pairing and the best time to deploy each weapon system against threat(s) it is paired with in arriving at the pairing. This results in an optimal assignment where weapon resource constraints are not exceeded and therefore guarantee availability of sufficient resources for engagement of every threat that is paired with a weapon system.

This invention is a line throwing rescue gun which is inexpensive and easy and efficient to use. The rescue gun utilizes a combustible gas which is sprayed into a chamber of the rescue gun and then igniting thereby propelling a projectile attached to a line over a substantial distance. The invention is also a method for using a rescue gun wherein the projectile is greased and ramrodded into the barrel of the rescue gun, whereby an aerosol combustible gas is sprayed into the chamber of the rescue gun, the chamber is sealed and the gas is ignited thereby propelling the projectile through the barrel towards a specified target.

A contamination-free pyrovalve having first tubing section and a second tubing section. The first and second tubing sections are disposed in spaced-apart relation such that a conveying path between the first and second tubing section is established. An opening is disposed between the first and second tubing sections. A valve body is fixedly attached to the first and second tubing sections. The valve body has a bore. A ram is disposed inside the bore of the valve body. A slug is disposed in the opening between the first tubing section and the second tubing section. The slug is held in position by a frictional fit. A combustion chamber is disposed in operative relation to the ram such that when an explosive material is ignited the pressure inside the chamber causes the ram to move through the bore to strike the slug and to displace it from the opening between the first and second tubing sections such that the valve is opened.

A stackable thru-tubing perforating gun system for use in perforating in a large diameter cased wellbore below a smaller diameter production tubing string. The system comprises a thru-tubing retrievable bridge plug for supporting a lower perforating gun section. The system further comprises at least one additional gun section stacked on top of the lower gun section. After firing, individual gun sections may be retrieved from the wellbore through the tubing string.
摘要:
A laser energy window arrangement especially usable in a tactical aircraft having night vision equipment-aided cockpit visual information input requirements. The laser energy window arrangement enables use of laser apparatus directed external to the aircraft for target designation or other purposes while minimizing the amount of energy from such laser returning spuriously inside the cockpit where it inherently acts a noise signal for night vision equipment. The laser energy window limits the portion of the aircraft windshield or canopy exposed to laser radiation and its effects to a relatively small area, an obscurable area generating significantly reduced amounts of spurious return energy in comparison with use of the laser directly through an unlimited windshield, canopy, or other type of transparency. Transmission of spurious return energy from the laser energy window to remaining portions of the windshield or canopy is precluded by interruption of transmission paths within the windshield or canopy material and transducing the interrupted path energy into heat dissipated within or outside of the aircraft and not affecting the remainder of the canopy. Potentially increased aircraft to target standoff range, reduce need for aircrew use of laser eye protection gear, reduced laser induced windshield or canopy degradation and other benefits are identified for aircraft uses of the invention. Use of the window invention in other non aircraft and non military aircraft settings is also contemplated.
