Rotating-to-static seals are critical components of all gas turbine engines. The seals can significantly affect the efficiency, operability, and durability of a gas turbine engine. As such, any improvements to these seals are highly desirable. Improvements may come in the form of reduced leakage and/or improved seal durability. The Air Riding Seal technology is a rotating-to-static seal that redu ...

The need to access parallel computing resources is ever expanding, as both the scale of simulations and the size of data sets are quickly growing. Also, the increasing ubiquity of parallel hardwaremulti-core chips, parallel co-processors and accelerators, near effortless cluster computing on cloud infrastructurespush new and existing high-performance computing (HPC) users to move to parallel pro ...

The problems with current pure niobium (Nb) superconducting radio frequency (SRF) cavities are that manufacture is expensive; cavity performance is often poor; and manufacturing results are inconsistent. These problems stem primarily from three factors: (i) the high cost of pure Nb, (ii) a poor and inconsistent microstructure in the starting niobium material, and (iii) seam welding to manufacture ...

As outlined in the document, Technical Topics Descriptions, FY 2012, Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) Programs, July 2011, page 137: Sn-117m has gotten a lot of interest in the last few years. It has favorable nuclear properties for both imaging and therapy. However commercial quantities of the isotope at high specific activity are not availa ...

Diamond possesses excellent particle detection characteristics, which makes it indispensible for its use in the radiation hard ultra-fast detectors for high energy physics applications. For such applications, damage free, ultra-smooth chemical vapor deposition diamond substrates of large area are required. Though large area polycrystalline diamond substrates are currently available in the market ...

During the Phase I SBIR Effort, Mainstream demonstrated a unique vehicle monitoring system (VMS) for tractor trailer applications. The development was driven by the need to easily store, retrieve, and transfer key trailer parameters to the tractor and the need to electronically transfer key driver, tractor, and trailer information to roadside inspectors and maintenance personnel. In Phase I, we ...

Phase II Project Scope: ATI has developed an open source Signal Control Programming Environment (SCOPE) that ➢ Implements Actuated Control with Min Recall Mode, Max Recall Mode, Gap Out Mode, Max Out Mode, Presence Mode, Lane-by-Lane Control. ➢ Contains a Pretimed Mode allowing control of 3-leg, 4-leg, and Texas Diamond Intersections ➢ Can be easily ported to any operating system. ➢ Can ha ...

There exists a wide-range need in both industry and government for quantitative residual stress measurements. Generation 2 Materials Technology LLC (G2MT) will collaborate with partners from industry and government to calibrate and commercialize the eStress system to assess residual stress from mechanical damage and re-rounding. The industrial members, consortiums, and government laboratories who ...

One of the most important numerical problems in science and engineering is that of finding the eigenvalues and eigenvectors of large-scale matrices. Methods for the solution of these problems, usually called eigensolvers, are fundamental to many industrial and scientific applications ranging from computational chemistry problems to structural design, to other modeling- and simulation- intense disc ...

At the present time, carbon fiber tanks are very expensive, with the high pressure vessel industry standard Toray T700 carbon fiber costing between $20 and $50 per kilogram alone. At this high price, the carbon fiber currently comprises as much as 75% of the overall tank cost and is a major roadblock on the path to commercialization. To make hydrogen fuel cells in early market and light-duty vehic ...
