This STTR is aimed at developing methods and tools to characterize the impact of free-play on control surface flutter and overall stability and performance of the system. A successful completion of this two-phased STTR effort will lead to a modeling, analysis, design, and simulation tool that will provide a state-of-the-art capability for stability and performance analysis for any generic control ...

During initial design studies, parametric variation of vehicle geometry is routine. In addition, rotorcraft engineers traditionally use the wind tunnel to evaluate and finalize designs. Correlation between wind tunnel results and flight tests, when not good, have been often attributed in part to uncertainty in blockage corrections. Estimation of rotor blockage is significantly more complex than bl ...

In this highly interconnected world, transportation systems must feature increased flexibility and shorter door-to-door trip times to be successful. Shorter door-to-door trip times require an increased usage of rotary wing and runway independent V/STOL technology. One of the limiting factors to the increased adoption of this technology for providing feeder service to major hubs is the limited un ...

DESCRIPTION (provided by applicant): Chemotherapy drugs tend to be highly cytotoxic and genotoxic, with well-documented carcinogenic, mutagenic, and teratogenic effects. Long-term occupational exposure to these highly toxic drugs presents serious health risks (e.g., cancers, infertility, miscarriages, birth defects, spontaneous abortions, and congenital malformations) to over 5.5 million healthcar ...

DESCRIPTION (provided by applicant): Ataxia-telangiectasia (A-T) is a multi-systemic, recessively inherited disorder that affects between 1 in 40,000 to 1 in 100,000 individuals worldwide. It is characterized primarily by early onset cerebellar ataxia andtelangiectasia, from which the disease name is derived. In addition, patients also exhibit a number of other clinical symptoms including increase ...

Human Campylobacter disease caused by the foodborne pathogens, Campylobacter jejuni and Campylobacter coli, is a huge public health problem globally. The economic burden of this disease, which ranges from mild self-limiting diarrhea to devastating neurological complications, in the United States alone is estimated at more than USD 8 billion annually. Broiler chickens harbor these pathogens in thei ...

Rural communities, comprised of both residential and commercial buildings, are struggling to maintain their populations and the vitality of their downtown districts and schools. They are spending significant dollars on energy bills and wasting as much as 25% of that energy. Buildings accounted for 81% ($294 billion) of total dollars spent on U.S. electricity in 2008 and consumed more than 50% of t ...

DESCRIPTION (provided by applicant): Aortic aneurysms and dissections are a cause of frequently preventable death for over 13,000 people annually in the US alone. Many more patients live under a constant threat of a catastrophic aortic event from atherosclerotic or congenital causes. Therefore, early and comprehensive diagnosis of morphological or dynamic changes in the aorta is of great importanc ...

This Small Business Innovation Research Phase I project will develop a fiber optically coupled in situ probe utilizing a superluminescent diode (SLD) optical source for monitoring bioreactor fermentations with ASL?s bioreactor monitor. The current ASL monitor uses a conventional, thermal light source, which is inherently low-brightness and will significantly reduce the instrument?s throughput and ...

ASW training requires an accurate simulation of both sonobuoy data content and geolocation in order to maintain peak crew proficiency. Unfortunately, existing systems can generate and emit the necessary field of 64 sonobuoy signal simulations, but without the geographic dispersion of a real sonobuoy pattern (which is an unaffordable training option and unrealistic/uncontrolled simulation scenario) ...
