In this SBIR program, QuesTek Innovations LLC will apply its computational materials methodology to develop ICME tools that directly address the unique complexity of additive manufacturing (AM) processing. CALPHAD-type modeling along with materials property and process evaluation will be applied to make an intelligent selection of commercial heat exchanger (HX) alloy(s), or composition optimizatio ...

Electron Beam Additive Manufacturing (EBAM) is a layer additive manufacturing technology capable of producing refractory metal (C103, Ta-10W) components from a computer generated 3D CAD model. These near net shaped preforms utilize significantly less material and require substantially less machining than the current process being used.

Research the use of laser powder bed fusion to provide a lower cost method to manufacture complex geometries in C103 and other refractory metals.

WE PROPOSE HERE THE CONCEPT OF THE ACTIVE ACOUSTIC GRILLAGE; AN AIR GRILLE COATED WITH THIN ACTIVE SKIN ACTUATORS. THIS GRILLE WOULD REPLACE PASSIVE GRILLAGES COMMONLY USED TO EXCLUDE FOREIGN OBJECTS FROM FAN INLETS AND OUTLETS. ACOUSTIC CONTROL CONSIDERATIONS DEMAND THAT SUCH A GRILLAGE HAVE A CROSS-FLOW CELL SIZE SMALL COMP[ARED TO ACOUSTIC WAVELENGTH; 6 INCHES AT 2 kHz. CONVENTIONAL GRILLAGES M ...

Developing secure cryptography to meet the constraints of a given application is currently a difficult, time-consuming, and error-prone process. Recent research suggests, however, that the work of evaluating the security of cryptographic algorithms, and of exploring the security tradeoffs of alternative designs within a general class, can be at least partly automated. We propose to build a compreh ...

A compact fiber-based low-power miniature laser rangefinder (LRF) will be developed and shown to provide superior ranging performance within the demanding size, weight, and power (SWAP) requirements of existing and planned photonics masts, such as found on Virginia- and SSGN-class submarines. The LRF includes a 6-ns pulsed 1-mJ miniature laser, a temperature-compensated avalanche photodiode (APD) ...

Biomass heating/cooking stoves in developing countries do not efficiently cook food or heat houses, while consuming too much fuel and emitting pollution resulting in respiratory illnesses, premature death, and climate change. Affordable technologies found in 1.) EPA approved heating stoves, 2.) DOE funded cooking stoves, and 3.) TEG (thermoelectric generation) lighting devices, improve heating, co ...

The Navy has expressed a need for an ultrafiltration or direct osmosis concentration (DOC) system that can 1) concentrate shipboard graywater/secondary oily waste to at least 95%, 2) reject 95% of the heavy metals, and 3) produce an effluent with BOD levels less than 30 ppm. In response to that need, Osmotek proposes to develop a DOC system that shows exceptional fouling resistance, will have meta ...

1We are proposing a computerized tomographic (CT) dimensional measurement system that will remedy two of the major problems experienced by current methods: the distortions caused by CT artifacts, and the blurring caused by the system point - spread function (PSF). The distortions resulting from data nonlinearity will be corrected by a calibration process acting upon the x-ray data. The blurring er ...

The objective of the proposed project is to develop a lightweight, robust, and modular system, capable of harvesting solar energy in areas with dense foliage cover in an effective manner. The system proposed will be able to reach a height of 100 feet above an average tropical forest canopy to deploy a solar array capable of generating 250 W under AM1.5G 1-sun illumination. In this proposal, MicroL ...
