This SBIR Phase II proposal will design and develop a reactive nanofiber based heating, ventilation, and airconditioning (HVAC) air filter to capture corrosion inducing particulate matter (PM) and dissolved ions present in coastal region air. Nanoparticle-polymer will be combined to produce high surface area reactive nanofiber filtermedia. The performance of media will be tailored by controlling ...

ABSTRACT: Combustion instability (aka thermoacoustic instability) is a significant issue in propulsion systems including augmentors. Oscillations can increase heat transfer to walls 10 fold and cause vibration damage to the propulsion system and the surrounding system. This damage can occur very rapidly. Combustion instability (CI) is challenging to design for due to the complex interactions betw ...

ABSTRACT:The SBIR primary objective will be to show the feasibility of advance modeling for simulating and predicting the surface corrosion leading to fatigue damage. This capability will produce early-life stage models which will enhance state of the art corrosion analysis. The SBIR conceptual modeling method must address small damage, in a corroded microstructure for fatigue crack growth. The me ...

ABSTRACT:The damage tolerance approach is used widely in the aerospace industry and has a physics-based foundation in fracture mechanics. The fatigue crack growth rate can be determined by calculating the SIF (stress intensity factor) and knowing empirically derived material parameters. Similitude is achieved for different loads, different crack sizes, and different crack shapes. The down side to ...

WE PROPOSE THE EXTENSION OF A NEW ANALYTICAL TECHNIQUE, SPUTTER INITIATED RESONANCE IONIZATION SPECTROSCOPY (SIRIS) TO INCLUDE DEPTH PROFILING. THIS PHASE I PROJECT WILL DETERMINE THE FEASIBILTY OF MAKING THIS PRELIMINARY MEASUREMENTS USING THE SIRIS TECHNIQUE ON STANDARD SAMPLES OF SI DOPED ALGAAS AND TI DOPED LINBO3. SUCH SAMPLES ARE OF INTEREST TO THE AIR FORCE'S VHSIC AND ELECTRO-0PTIC DEVELOP ...
