The objective of this project is to develop and validate an improved technology base for the cold-working of high strength aluminum alloys. The improved technology base consists of the following three legs: 1. A test-validated CAD/CAM tool for performing virtual cold-working and for virtual fatigue testing. 2. An improved design mandrel to achieve the full life improvement potential of cold-w ...

This SBIR Phase I project proposes the feasibility study of integrated all-optical 2R regeneration and 3R optical signal regeneration devices for use as high-speed interfaces in satellite applications (solicitation AF04-043). Currently available products achieve regeneration of signals by resorting to Optical to Electrical and then Electrical to optical conversion (OEO), which results in costly, ...

Organic film polymers have been the dielectric of choice for high voltage, microsecond-discharge, high energy density capacitors. Electron traps normally found in these films limits their maximun voltage breakdown strength, engergy density, and dissipation. The objective of this proposal is to demonstrate the feasibility of producing higher performance polymer-like dielectric materials without ca ...

Development of three Bipropellant Tank designs with mechanically linked pistons for Advanced Small Missile Systems. The study will consider the technical and fabrication issues associated with the design, and rate the comparative merits leading to the selection of Phase II continuation.

The objective of the proposed research is to develop new technologies based on principles of Time Reversal Acoustics (TRA) that will provide highly sensitive land mine detection. We suggest applying the Time Reversal Acousto-seismic method in combination with a nonlinear acousto-seismic mine detection technique. The TRA focused system provides a high concentration of seismic wave energy at any des ...

The objective of this proposal is to develop a Muscle Water Content (MWC) sensor, an ultrasonic device for assessment of body hydration status in soldiers with accuracy better than 2% during deployment and training. The MWC assessment is based on measurement of ultrasound velocity in muscle, which is, to a good approximation, a linear function of the water content. The expected outcome will be ...

In Phase 1 we will demonstrate the feasibility of integrating high-speed InP-based HEMTs with ASIP's proprietary asymmetric twin waveguide photonic integration technology. A common source HEMT driver transistor will be integrated with a simple, asymmetric twin waveguide (ATG) compatible laser. In Phase 2, we will extend this feasibility demonstration to demonstrate an EPIC consisting of a single ...

We have selected three technologies for the remote monitoring of bio-behavioral events. Camera based measures of gaze, including eye and head movements, pupil diameter, vergence, and blink parameters; Laser Doppler Vibrometry (LDV) based measures of cardiovascular and muscle activity; and behavioral measures including movements of body parts as well as keyboard operations will be utilized. Our co ...

Current turbomachinery designs have been optimized, for the most part, using "average flow" design concepts and tools. Future advances in engine performance, especially with regard to increasing per stage pressure ratio, stall margins, and reduced sensitivity to inlet distortion in fans/compressors, must come from innovative technologies which move beyond the current "steady flow" design space. ...

Accurate performance prediction is crucial to the simulation, analysis and flight testing support of rotorcraft. In this regard, current analysis tools inadequately model key phenomena like blade dynamic stall, rotor tip loads, and rotor downwash because of their failure to predict the true unsteady three-dimensional nature of the aerodynamic environment near the rotor.
