ABSTRACT: Microbial contamination in kerosene based aviation fuels has been a problem for the USAF since the 1960"s. Antimicrobial effect of earlier used fuel system icing inhibitor (FSII) became an initial solution to this problem, but later, such fuel additives were banned due to their extreme toxicity towards humans. Newer FSIIs, being more eco-friendly, do not possess the antimicrobial prope ...

The focus of the Phase II project will be on design, fabrication, and testing of an adaptive vertical support group AVSG with an active shock and vibration control system (ASVCS) that can mitigate shock and vibrations and increase mission capability for and to support variable payload systems. The Phase II effort will be conducted on the AVSG mount, test fixture development, design and development ...

Recent efforts at improving shipboard operations have focused on desalination systems. One area in which manpower may be significantly reduced is in the monitoring chlorine residuals from hypochlorite enhanced streams that are used for periodic biofouling control flushes of microfiltration membranes. These are used for pretreatment of seawater prior to exposure to reverse osmosis membranes used fo ...

A new, improved fidelity solid rocket ballistics model is being built on a commercial CFD platform. The CFD platform includes a coupled solid mechanics solver, allowing for tight coupling between the grain burnback and the motor gas dynamics. An aeroacoustic component of the platform will be used to determine mode shapes and acoustic decay characteristics from the ballistics results.

An innovative tunable vibration absorber (TVA) concept was developed in the Phase I feasibility study. This design was selected among others to be developed in full scale in Phase II and Phase II Option based on a detailed theoretical modeling, smallprototype test results, and a cost analysis, which were conducted in Phase I.In Phase II and Phase II Option a new generation of TVA utilizing a clas ...

A study of the application for a visible light camera based on placing a Delta Sigma modulator at each pixel to provide per pixel A/D showed the potential for superior performance compared to alterate APS designs. It was demonstrated that substantiallyhigher fill factor and smaller pixel size could be achieved using common CMOS technology. Well capacity and linearity of the sensor were also shown ...

Ascension Technology proposes to develop a fast, six degrees-of-freedom tracker, phasorBIRD, immune to cockpit and helmet scatterers of magnetic/electrical field energy. It will integrate seamlessly with helmet-mounted displays in tactical aircraft,tracked ground vehicles, and combat air operations centers (CAOCs). Design features will enable it to exceed static accuracy and repeatability of the b ...

There is a significant opportunity to meet higher upper stage engine performance levels by combining a much higher chamber pressure expander cycle engine with advanced technology turbomachinery. The Phase II SBIR goal is to provide a solid foundation foran upper stage engine design focused on IHPRPT goals. Three main Phase II technical objectives must be met to achieve this goal: 1) finalize th ...

The U.S. submarine force strongly desires an improved situational awareness and a collision avoidance capability based on intercept of active emissions and detection of passive broadband signals. Our Phase I SBIR focused on the development of rapid 3D(range, bearing and depth) localization solution against active emissions detected on existing submarine sensors. The results of our Phase I study sh ...
