Over the last decade, it has been noted that offshore wind energy resource development could prove extensively valuable in many areas of our nation’s growth, including continued diversification of our energy supply, more options for cost-competitive electricity in coastal and Great Lakes regions, and economical stimulation through new and lasting infrastructure development. The challenges associ ...

ABSTRACT: The Air Force is seeking methods to enhance satellite responsiveness by developing autonomous flight software that supports on-board event detection, planning, and task execution. Key to autonomous flight software is a realistic simulation environment with realistic satellite models. ATA proposes a systems-driven methodology for producing high fidelity, realistic satellite models, a R ...

ABSTRACT: Investing in innovation that moves toward the widespread use of satellite autonomy has the potential to yield significant benefits to the space situational awareness (SSA) community. Most notably, if satellite platforms have the ability to detect and respond to events without exchanging information over the space-to-ground link (which is subject to latency and availability limits), thei ...

ABSTRACT: MZA partnered with the University of Notre Dame proposes to implement a series of mechanical and optical sensor measurements in a wind tunnel test section to isolate aero-optical disturbances from contaminating tunnel disturbances. We will develop a design for the necessary sensors and the number/location of these sensors on the tunnel observation windows. Particular attention will be ...

ABSTRACT: Ultra-high performance concrete (UHPC) materials with outstanding material properties offer significant promise to transform infrastructure design and service life. Evolution of UHPC into a mainstream construction material would benefit from the resolution of issues relevant to the restrictive selections of finer aggregates/fillers, large heat of hydration and thermal stresses, high aut ...

ABSTRACT: In this Phase I STTR project, we propose to demonstrate the feasibility of developing a low cost, compact, time-domain terahertz (TD-THz) spectrometer specifically for the characterization of semiconductor materials over a range of temperatures, electric fields, and magnetic fields. In phase I, we will configure fiber optic coupled TD-THz instrumentation to make measurements on a sampl ...

ABSTRACT: The goal of this phase II proposal is to develop a commercial platform for printing high performance, single-walled carbon nanotube transistor circuits on large-area plastic substrate. Automated processes will be developed for the room temperature printing of metal, semiconductor, and dielectric materials with micron-scale alignment accuracy. The transistor performance will be enha ...

ABSTRACT: Stellar Science has developed innovative techniques for satellite conjunction processing using spatiotemporally indexed ephemeris data. Our algorithms first insert each satellite into a spatially aware data structure, such as a K-D Tree or a Spatial Hash Table, and then it scans the data structure looking for satellite conjunctions. While traditional approaches to satellite conjunctio ...

ABSTRACT: We propose to develop a comprehensive, integrated software framework and toolset to support model-based engineering (MBE) of laser weapons systems. To be effective, MBE requires robust underlying modeling and simulation technologies capable of modeling all the pertinent systems, subsystems, components, effects, and interactions at any level of fidelity that may be required in order to ...

ABSTRACT: This program develops a Modular Propulsion system design and demonstration test bed that continues the efforts of the Phase I program that established the feasibility of a green propellant based modular propulsion system. Two reduced toxicity propellants will be considered: LMP-103S and AFM-315E. The mission type and the spacecraft size strongly impact the details of the modular propu ...
