Nanofiber nonwoven spunbonded materials technology is adapted for use in a personnel lowering device. The resulting device will be simple, easy to use, and relatively low cost.

In composites, not only can properties vary with load direction, fiber based composites also offer the unique ability to tailor material properties locally. Localized matrix or fiber architecture changes can meet local mechanical, electrical, or thermal loads within a component or vehicle, without weight penalty or resort to additional external structures. In Phase I, the team used 3TEX 3-D wea ...

Strength and durability of commonly used bonded and bolted composite-to-composite and composite-to-metal structural joints suffer from sharp geometry variations, mismatch of elastic moduli, Poisson’s ratios, coefficients of thermal expansion and thermal conductivity of the adherends, altogether causing high stress concentration and premature joint failure. The proposed work is focused on develop ...

This proposal offers an approach to integrate the latest corrosion sensor technology with corrosion structural effects modeling to enable the transition from periodic corrosion inspections to an efficient, focused prognostics and health monitoring (PHM) system. The fundamental vision of the proposed program is to provide the customer with a process suitable for integrating corrosion effects analy ...

We propose to develop a computer based system for the online analysis of bio-behavioral signals associated with momentary loss of alertness. We will continue our development of bio-behavioral measures indicative of lapses in alertness. Our system will use only measures that can be obtained without attaching sensors to the operator. We will concentrate on monitoring the oculomotor system using came ...

Brushfire Technologies proposes to adapt our secure local area network gateway to the unique requirements of the DMO network to detect, analyze and mitigate security threats in real time with no adverse affects on network performance. Security analysis based on real time packet inspection coupled with application awareness and heuristically derived network topology information provides unpreceden ...

The foundation of any counterspace capability is space/counterspace situation awareness. Existing AFRL/VS funded efforts have established a foundation for robust, multi-level situation awareness through multi-source, multi-level, data fusion. However, situation awareness is only useful to the extent that it informs response to threats, whether natural or man-made. AFRL/VS Space Awareness & Respons ...

A longwire antenna module is proposed, incorporating a length reduction technique that yields 25-75% length reduction with minimal impact on gain. A resonant monopole antenna operating at 535kHz is approximately 440ft long; length reduction techniques will reduce this to between 69ft and 134ft depending upon the desired gain. A shorter/lighter longwire antenna will allow the aircraft to be more ...

An antenna system is proposed for the purpose of FM, TV-VHF, and TV-UHF PSYPOS broadcast applications. The antenna system incorporates a radiating structure that is small, light weight, and conformal. A circularly polarized beam is broadcast from an aircraft towards nadir, illuminating the region below the craft with a horizontally-polarized signal, yielding polarizations pointing in both the No ...

A methodology is proposed to provide intelligence to more classical global optimization schemes. By incorporating these methods, design engineers will be able to not only identify and resolve difficulties within an antenna element, but will be able to synthesis and optimize an entire array, including the antenna elements, feed structures, array position and shape, element location and orientation ...
