Multi-scale Physics-Based Models for alpha-betaTitanium Alloys Accounting for Higher-Order Microstructure Statistics.SBC: MRL MATERIALS RESOURCES LLC Topic: AF09BT29
Modern military and civilian aircraft technologies are pushing the performance envelope through design and use of new advanced materials with superior property combinations. Aircraft powerplant manufacturers are facing intense competition to efficiently deliver ever increasing thrust, while meeting the highest standards of reliability and performance over an expanded service life. These performanc ...STTR Phase I 2010 Department of DefenseAir Force
SBC: Kassoy Innovative Science Solutions Topic: AF09BT38
Quantitative predictions of reactive flow dynamics from large-scale simulations of Liquid Rocket Engines (LRE) appear to be model dependent. Relationships and coupling among the dominant mechanisms most responsible for destabilization are obscured by the complexities of the model and subtle consequences of inherent ad hoc approximations not supported by mathematical rationale. The reliability of ...STTR Phase I 2010 Department of DefenseAir Force
SBC: Physical Engineering Corporation Topic: AF09BT39
This Phase I STTR proposal will demonstrate nanostructured “metal-black” coatings to enhance absorption by thin film solar cells. The problem is that silicon has low absorption due to its indirect gap. The opportunity is that nano-scale metallic scattering centers increase the effective optical path length and enhance the solar electric-field strength in thin-film solar cells, leading to more ...STTR Phase I 2010 Department of DefenseAir Force
SBC: OMITRON, INC. Topic: AF09BT02
Currently, computation of the geopotential acceleration and its partial derivatives consumes a large portion of numerical integration time in special perturbations (SP) applications. The standard geopotential formulation is expressed as a spherical harmonic expansion in geocentric latitude, geocentric longitude, and radial distance. Recent research by Dr. Beylkin of the University of Colorado ha ...STTR Phase I 2010 Department of DefenseAir Force
SBC: Intelligent Automation, Inc. Topic: AF08T011
We present a comprehensive framework for modeling, optimization and design for heterogeneous networks. The proposed solution aims to effectively address the existing limitations inherited from the generalized network utility maximization (GNUM) framework. In general, GNUM is a unifying mathematical model as it combines different objectives and constraints from different layers into a single global ...STTR Phase II 2010 Department of DefenseAir Force
SBC: AURORA FLIGHT SCIENCES CORPORATION Topic: AF08T026
Aurora and Georgia Tech"s Phase I efforts demonstrated the feasibility of a partially distributed control scheme with separate controllers on the engine core and fan, where the controllers are linked by a supervisory controller. This scheme is representative of the situation encountered in VTOL UAV design and the design of new turbo-props and variable pitch turbofans by the large commercial gas t ...STTR Phase II 2010 Department of DefenseAir Force
SBC: NEW SPAN OPTO-TECHNOLOGY, INC. Topic: AF08T001
Two-dimensional (2D) visualization techniques have limit capacity to achieve understanding of full dimensionality of the battlefield. Rewritable 3D holographic storage is promising for updatable 3D display applications. In Phase I, New Span Opto-Technology has demonstrated novel concepts of both holographic recording technique and recording material system without the use of high voltage. We have ...STTR Phase II 2010 Department of DefenseAir Force
SBC: SPECTRAL ENERGIES LLC Topic: AF08T010
The objectives of this Phase-II research effort is focused on transitioning noninvasive diagnostic techniques based on ultrafast lasers for characterizing nanoenergetic materials and their performance in rocket engine environments. Through the use of ultrafast laser imaging and spectroscopy, it is possible to isolate and characterize each physical process from initiation through energy release an ...STTR Phase II 2010 Department of DefenseAir Force
SBC: Intelligent Automation, Inc. Topic: AF12BT02
ABSTRACT: Detection of clandestine tunnels and underground facilities is a continuing interest of the US DoD and Customs and Border Protection. Research continues in an attempt to find functional and reliable sensing methods, including seismic methods. Dynamic activity in tunnels emits mechanical energy that propagates away in seismic waves. Resulting ground vibrations can be measured at offset d ...STTR Phase I 2013 Department of DefenseAir Force
SBC: i2C Solutions, LLC Topic: AF12BT04
ABSTRACT: Adversarial installations, such as those housing the means for nuclear weapons production, are increasingly being constructed in heavily fortified locations and often using ultra high performance concrete (UHPC) as the construction material. As such, the U.S. Air Force has considerable interest in further developments of ultra high performance concrete (UHPC) to maintain an advantage o ...STTR Phase I 2013 Department of DefenseAir Force
