Improved head and hearing protection is required for aircraft maintainers working on a carrier flight deck during launch and recovery operations. The current head protection is inadequate in many aspects including impact protection, hearing protection, cleaning, comfort, and compatibility with night vision goggles (NVGs) and with chemical, biological, and radiological (CBR) equipment. Creare pro ...

The development of a process to produce low defect density silicon carbide (SiC) boules at high growth rates will significantly reduce the cost of wafers and thus accelerate the rapid commercialization of SiC for high power and high temperature device applications. The objectives of this Phase II project is to improve the process development of a radically new approach to grow bulk SiC of a singl ...

The current methodology for testing the penetration resistance of textile materials to various chemical agents has a number of drawbacks, including significant uncertainties in the resulting data, inefficiency and expense, risk to test personnel, and limited range of test conditions. The objective of the proposed work is to apply unique computer models for textiles with accompanying experimental ...

Sensor Electronic Technology, Inc. proposes a radically different approach for pushing the GaN HEMT performance above the 200 GHz range. In this approach, called Drain Gate Recess, the shape of the recessed gate is such that the gate metal is CLOSER to the channel near the drain edge of the channel. The result is a variation of the device threshold voltage along the channel that makes the electr ...

Lithium oxyhalide batteries offer energy densities several times higher than thermal batteries. Like thermal batteries, lithium oxyhalide batteries have unactivated storage lives in excess of 20 years and are mechanically rugged. Some of the main advantages that lithium oxyhalide batteries offer are flat discharge voltage profiles and potentially long operating lives. However, battery performanc ...

Advanced space-borne infrared detectors require cooling at temperatures near 10 K. Cooling loads for these detectors will range from 0.25 W to 1.0 W at 10 K, with additional loads at higher temperatures. A multistage cooler, capable of cooling multiple loads, will offer large potential gains in system efficiency and weight. Turbomachine-based Brayton cryocoolers are ideal candidates for these m ...

The projected cost for the Mentis Sciences, Inc., (MSI) prototype PAC3 radome is 1/6th of the total cost of the present system. A Pareto analysis of the current MSI process indicates that the two largest costs in radome production are the direct labor associated with fabrication and the cost of the raw materials. In Phase I MSI demonstrated that COTS paint spraying technology reduced the direct ...

The Architecture Analysis and Design Language (AADL) is an SAE standard language for describing the software and hardware architecture of performance-critical real-time systems. In addition, the AADL standard allows the definition of annexes, i.e., formal extensions to the standard language to enhance the design specifications of hardware or software components. We propose to leverage the AADL la ...

Power generation, power distribution and electric propulsion on ships and aerospace vehicles could be made smaller, lighter, more efficient, more versatile, and lower maintenance by operating these systems—partly or entirely—at cryogenic temperatures. Our goal is to demonstrate the advantages of cryogenic operation in regard to electronic components, specifically semiconductor devices (power d ...

Solid State Scientific Corporation proposes an triangular barrier photodiode (TBPD) detector for use on a dual mode sensor. The TBPD will function as a passive low-light visible-SWIR imager at long range and as a 3-D LADAR sensor at short range. The TBPD has the advantage of increased optical gain with decreased incident power, making it very attractive for applications with weak target signals, ...
