A data dictionary and additional information is located on the Data Resource Page. Files are refreshed monthly.
The SBIR.gov award data files now contain the required fields to calculate award timeliness for individual awards or for an agency or branch. Additional information on calculating award timeliness is available on the Data Resource Page.
SBC: MZA ASSOCIATES CORP Topic: N10AT035
Current software development and testing methodologies are inadequate for validating software in mission-critical applications. As Dijstra famously stated: "testing can be used to show the presence of bugs, but never to show their absence." When lives and national security is at stake, there is a need for mathematically rigorous techniques that can verify the absence of bugs. We propose to devel ...STTR Phase I 2010 Department of DefenseNavy
SBC: KITWARE INC Topic: N10AT029
Analysts are faced with the challenge of sifting through enormous quantities of documents, blog posts, communications, etc. to find deceptive behaviors. We propose novel techniques for efficiently and automatically detecting deception on large data with high accuracy by using methodologies from both stylometry and topic modeling. This combined approach will learn models of authors and will detect ...STTR Phase I 2010 Department of DefenseNavy
A Fast-Response, Electronically Controlled Fuel Injection System for Small Heavy Fuel Engines with Multi-Fuel CapabilitiesSBC: MAINSTREAM ENGINEERING CORP Topic: N10AT033
Advances in electronically controlled injection technologies for diesel engines have provided a method to improve medium- to heavy-duty engine performance through increased injection pressures, multiple injections, and injection rate shaping. Although these injection systems have been primarily limited to larger engines, the ability to rapidly and precisely meter fuel for smaller engines is partic ...STTR Phase I 2010 Department of DefenseNavy
SBC: MAINSTREAM ENGINEERING CORP Topic: N10AT037
In miniature gas turbines for UAV applications, traditional bearings exhibit a typical lifetime of only 25 hours due to excessive axial loading. Mainstream proposes to use a passive, permanent magnet thrust bearing to alleviate this problem and increase service life to over 1000 hours. Since this type of bearing is non-contacting, it can operate at very high rotational speeds with minimal heat gen ...STTR Phase I 2010 Department of DefenseNavy
SBC: XDOT ENGINEERING & ANALYSIS PLLC Topic: N10AT037
Micro gas turbine engines with state-of-the-art ultra-compact recuperators could be a real game-changer for small unmanned air vehicles and portable power generation. A key enabling technology for these engines is a low-cost, high speed bearing system that has long life, while operating without either a separate lubrication system, or oil in the fuel. For this Phase I STTR effort, Xdot Engineerin ...STTR Phase I 2010 Department of DefenseNavy
SBC: PROGENY SYSTEMS, LLC Topic: N10AT016
Stealth is a primary consideration in design and operation of ships and submarines in the Navy fleet. Noise in hydraulic systems and piping is one source of unwanted noise. A method to measure and monitor this noise is essential to controlling and eliminating these noise sources. With the assistance of UMASS Dartmouth we will present a method to externally measure the fluidborne sound pressure lev ...STTR Phase I 2010 Department of DefenseNavy
SBC: TDA RESEARCH, INC. Topic: N10AT025
Electromagnetic launchers or rail guns are a key component of the Navy’s all-electric ship of the future, but they lack the durability required for repeated firings. TDA Research and the University of Nevada, Reno (UNR) are developing a tough, durable and conductive refractory metal coating that will protect the copper alloy conductors (rails) from the extreme heat and wear conditions inside the ...STTR Phase I 2010 Department of DefenseNavy
SBC: BARRON ASSOCIATES, INC. Topic: N10AT024
The Barron Associates/Virginia Tech team believes that intelligent use of ambient riverine environmental factors together with novel drifter design and low-energy articulation is the key to enabling large non-overlapping river coverage. The proposed phase I research program focuses on (1) identifying key river characteristics which may be leveraged by riverine drifters, (2) fabricating a novel riv ...STTR Phase I 2010 Department of DefenseNavy
SBC: AURORA FLIGHT SCIENCES CORPORATION Topic: N10AT008
Aurora Flight Sciences and MIT propose to develop a model-based adaptive health estimation and real-time proactive control to identify gas turbine engine stability risks and avoid them through control action. In this concept, the engine control system actively monitors sensors and actuators, compares them against physical models, and infers which components may be performing poorly and may need to ...STTR Phase I 2010 Department of DefenseNavy
SBC: Impact Technologies Topic: N10AT009
Impact Technologies and Montana State University propose to develop a Dynamic Prognostic and Health Management (PHM) modeling capability and related test, validation, and support toolsets that will enable standardized approaches to model representation, information exchange, and PHM system support, providing for improved integration, interoperability and reuse of developed and emerging capabilitie ...STTR Phase I 2010 Department of DefenseNavy
