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 ...

The Phase I work has clearly demonstrated the feasibility of the Multi-Disciplinary Computing Environment (MDICE) for prediction and control of twin-tail buffet of fighter aircraft. Several flow control methodologies have been proposed and appliedsuccessfully to a generic fighter aircraft to reduce the twin-tail buffet responses. A new method of flow control using normal leading-edge blowing has ...

The objective of this project is to develop multiscale simulation tools for coupled carrier-phonon transport in micro/optoelectronic devices and to explore novel concepts of phonon engineering for heat removal and termal management in advancedsemiconductor devices. The phase I effort resulted in a prototype software modules for multiscale simulation of phonon dynamics in LD semiconductors and prov ...

Radiation-hardening by design (RHBD) allows to use available commercial fabrication lines of high performance circuits, but the radiation-hardened (rad-hard) devices and cells require larger area, higher-power consumption, and slower performance. CFDRC incollaboration with Mission Research (David Alexander) and Vanderbilt University (Ronald Schrimpf) is proposing to develop novel, radiation-harden ...

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 ...

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 ...

The objective of this proposal is demonstrate the feasibility of developing a re-configurable electronic system to produce a programmable Advanced Data Link Simulator. LIT proposes a Phase I SBIR to demonstrate the feasibility of developing an adaptable,re-configurable Advanced Data Link Simulator Module (ADLS Module) using commercially available PLD based hardware and separate configuration fil ...

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 ...
