A NEW SYSTEM, THE ANNULAR FLOW ELECTROTHERMAL PLUG RAMJET, IS PROPOSED AS A ALTERNATIVE TO CHEMICAL ROCKETS AND ELECTROMAGNETIC LAUNCHERS AS A KINETIC ENERGY WEAPON. THIS SYSTEM APPEARS TO BE CAPABLE OF ACHIEVING THE HYPERVELOCITIES NECESSARY IN REASONABLE LAUNCHER LENGTHS, PRIMARILY BECAUSE IT DOES NOT ACCELERATE EITHER THE PROPELLANT OR THE PROPULSION SYSTEM REQUIRED TO ACHIEVE HYPERVELOCITIES. ...

Current drug discovery and development efforts are severely limited by expensive animal trials and oversimplified in vitro models. Results obtained from in vitro models are not predictive of in vivo toxicity owing to significant difference from the in vivo physiological conditions. In this context, we propose to develop and demonstrate a novel microfluidic device that reproduces the physiological ...

Product Authentication protects the CPI through the Weapon System Life Cycle. LIT Product Authentication is structured into two major components. The Product Authentication Key System (PAKS) derives cryptographic keys from authentication codes provided by the Product Authentication Sensor System (PASS). Equipment lost or compromised is protected from reverse engineering since any effort to open ...

Abstract The deciBel/SAIC Team Phase II effort will enhance and refine the design, development, and testing the prototype Environment Characterization and Clutter Mitigation Algorithms developed during Phase I. These enhancements will: 1) provide robustness, 2) permit for automation, while expanding applicability, and 3) ensure transition into current builds of BMDS sensor"s tactical software. T ...

The skin is the first line of defense against chemical warfare agents including nerve agents and toxic industrial chemicals, providing a possible barrier or delay to systemic distribution. Some chemicals also can act directly on the skin including the vesicants sulfur mustard and lewisite. Early and rapid skin decontamination is extremely important following exposure to CWAs and TICs because it de ...

We propose to develop and deliver 2-Color midwave/longwave infrared focal plane arrays (FPAs) and a camera based on Type-II InAs/InGaSb strained layer superlattice (SLS) sensor technology. 2-Color SLS FPAs with formats of 320x256 and 640x512 will be delivered, together with a portable 2-Color 320x256 camera. In Phase I, we designed and demonstrated the basic 2-Color midwave/longwave infrared SLS ...

Fielding of advanced missile defense interceptors is strongly dependent upon innovative concepts and technologies that can be applied across the Ballistic Missile Defense System to stay ahead of the threat, improve system capabilities and effectiveness, and lower life cycle costs. Tantalum carbide (TaC) based materials are being developed for potential employment as nozzle liners in axial thrust ...

Accuracies of initial alignment and gyroscopic drift in the presence of fast maneuvers and the settling time of gyroscopes and accelerometers govern navigation performances of Inertial Measurement Units (IMU) and of their associated Inertial Navigation (sub) Systems (INS). Most measuring devices include some electromechanical device, which has a time lag. In the case of IMU, the integration of mea ...

Fine powder thermal battery cathode materials can exhibit challenging flow properties which makes processing with automated presses difficult.Granulating these powders can substantially improve flow properties and reduce the tendency for powder segregation during handling and pressing operations.Additionally, the properties of MgO that lead to good performance in thermal battery separators are not ...

Diode-Pumped Alkali Lasers (DPALs) have great potential for high-energy lasers. Proper design of these systems is challenging because many interrelated processes impact their performance, and critical kinetic rate coefficients are not well known. In response, our team is developing a comprehensive physics-based analysis/design tool, and experimentally determining key kinetic rate coefficients. The ...
