It is proposed to develop novel eddy current probes based on spin dependenttunneling (SDT) magnetoresistive (MR) sensors to enhance the probability ofdetection of cracks within the bore of installed Taper Lok fasteners. Preliminaryresults show that the use of shaped excitation coils, together with extremelysensitive SDT sensors properly positioned above the structure under inspection,provides a si ...

AVEKA proposes the use of one of its proprietary leaching processes to dehydrate water-wet pelletized nitrocellulose (PNC). This is a process which will be safe, economical and will allow continuous processing during the dehydration step in thepelletization process. It is also a process that can utilize standard industrial leaching/extraction equipment with some modifications. The successful co ...

Military aircraft are largely constructed from special aluminum alloys, which typically have secondary precipitate phases that substantially improve mechanical strength. However, these regions also promote corrosion in such common environmental conditionsas acid rain, saltwater, and thermal cycling. The problem is significant enough that the U.S. Air Force expends approximately $1 billion per ye ...

This Phase I SBIR project will demonstrate the feasibility of a novel method for monitoring volatile organic compounds (VOCs) such as ubiquitous hazardous solvents in military or industrial environments and their neighboring communities. The long-termobjective of the project is to develop and commercialize a real-time, on-line and autonomous mid-infrared laser spectrometer specifically designed fo ...

Laser radars (ladars) have been investigated for the detection, classification and terminal tracking of military targets. One area of concern is the performance of automatic target acquisition (ATA) algorithms on targets that are stochastically obscuredby foliage. A program is proposed that will increase the understanding of target obscuration while increasing the set of non-proprietary ATA algo ...

The objective of this proposal is to demonstrate the feasibility of a halogen free nanocomposite vinyl ester system that will provide low flammability composites. The nanocomposite system proposed will be based on commercially available vinyl ester resinsand thus should not result in a significant increase to raw material costs. Layered silicate based nanocomposites are a relatively new class of ...

The overall goal of the proposed research is to develop a comprehensive, efficient, and well validated model of various remelting processes used for the production of ingots of superalloys and titanium alloys. Phase I research has demonstrated thefeasibility and the validity of developing a unified computational model for efficient and accurate prediction of AC and DC electromagnetics, fluid flow, ...

This program will develop high power, multiple frequency RF switches utilizing AlN substrates developed by Kyma Technologies, Inc. High-performance GaN-based devices, such as microwave transistors, have been demonstrated on sapphire and silicon carbidesubstrates; however, defects due to lattice and thermal expansion mismatch limit device performance. Dislocations significantly affect the performan ...

After four years of research, MicroPhase Coatings has invented a breakthrough silicone-silicate technology. Preliminary tests indicate that the coating is ice-phobic and meets requirements for aviation use. During Phase I we prove: (a) feasibility of usingthe coating to prevent ice buildup in B-2 engine inlets, and (b) compatibility with B-2 systems and Low Observable materials. During Phase I we ...
