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: Current separable thermal mechanical interfaces (STMIs) found in advanced digital processing electronics are unable to efficiently remove dissipated heat from the active electronics, limiting electrical performance far below their capability. The standard approach produces high thermal resistance (~1.0°C-in./W) with local variations in excess of +/-25%, severely limiting allowable ele ...

ABSTRACT: The Air Force uses specially designed facilities to perform ground testing of infrared detector focal plane arrays at Arnold Engineering Development Center (AEDC). The current approach for cooling the detectors down to 8 K utilizes liquid helium. The systems to transport and store the liquid helium are expensive to operate and wasteful due to the loss of liquid helium to boiloff. Hel ...

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 efficient, effective balancing of jet engine rotors and subassemblies continues to be a challenge for key aerospace applications. While manufacturing methods for balancing have improved significantly over the last ten years, measurement methods and procedures and fixturing have not advanced at the same pace. Modern jet engines require multiple parts and subassemblies to be balance ...

ABSTRACT: Accurate determination of the distance between fastener holes and part edges is critical to ensure structural integrity in military aircraft. These measurements are particularly important as part flanges are reduced and tolerances are tightened to save weight and increase performance. Current measurement methods rely on manual calipers and are extremely time consuming, labor intensive ...

"Remotely sensed data has an inherent physical detachment from the environment being sensed. At a high-level, we propose leveraging Oblong Industries"revolutionary g-speak platform to restore fully embodied situational awareness through multimodal interaction within the ICEbox environment. The g-speak spatial operating environment (SOE) is the world"s first fully-embodied, spatially aware comput ...

This accelerated program has provided a unique low-cost propulsion system for the Low Cost Autonomous Attack System (LOCAAS) weapon and other miniature smart munition systems.Combined commercial and SBIR-Phase I funding in the initial stage of this program has provided a new, fully operational, engine-generator systems for small air vehicle application.This new turbojet engine system uses existing ...

ABSTRACT: In this proposal we describe a highly flexible, ultra low-lower power GNSS receiver. By building the receiver from the ground up with flexibility and ultra-low voltage in mind, we are able to achieve a 5-20x improvement in energy-efficiency while providing support for a wide variety of GNSS codes. The proposed flexible code generator is able to efficiently support C/A, L2C, M, P, and L5 ...
