ABSTRACT: Performance of space-based digital control systems is limited by the low resolution of available radiation-hardened Analog to Digital Converters (ADCs) and Digital to Analog Converters (DACs). Applied Technology Associates (ATA) proposes to develop a High Resolution ADC on an Application Specific Integrated Circuit (HRADC-ASIC) that provides: Up to 16-22 bits of resolution with corre ...

ABSTRACT: The physical scalability of Si based nonvolatile memory is problematic for the terascale integration of space memory. In particular and with regards to Flash, this problem is two-fold as device designs breakdown and photolithographic patterning approaches its limits to minimum feature size. Whereas phase-change and ferroelectric polymer devices have shown promise to scale beyond Flash ...

ABSTRACT: This Air Force Phase I SBIR program would develop and demonstrate radiation hardened graphene based nonvolatile memory(NVM) for space applications. Specifically, we would combine advances in resistive memory materials, including graphene and graphene oxides, with the careful manipulation of metal ion, oxygen vacancy or other charge transport in graphene based materials, to realize the r ...

ABSTRACT: MicroLink and its collaborators, Rochester Institute of Technology and Magnolia Solar, will develop a high-efficiency, single-junction, epitaxial lift-off (ELO) GaAs solar cell by incorporating nano-scale features, such as quantum dots and optically functional textures, within the solar cell structure. The principal technical objective of the project is to increase the AM0 efficiency o ...

ABSTRACT: Optical refrigeration is currently the only demonstrated all-solid-state cryocooling technology. Optical cryocoolers use laser light to cool small crystal or glass cooling elements. The cooling element absorbs the laser light and reradiates it at higher energy, an example of anti-Stokes fluorescence. The extra energy of the outgoing light comes from the thermal energy of the cooling ele ...

ABSTRACT: CU Aerospace (CUA) and team partner the University of Illinois at Urbana-Champaign (UIUC) propose to perform research, development and demonstration of experimental quenching free measurements of heat-release in a realistic highly turbulent plasma-assisted flame. Kinetics models will be correspondingly updated and detailed 3D multiphysics simulations will be validated by the measuremen ...

Laser & Plasma Technologies (LPT) is proposing an optical fiber coupled corrosion treatment system, in which a unique thermographic imaging technique is used for early detection of corrosion. Combined with fiber laser removal and repair technologies, the system provides the capabilities of corrosion detection, removal, cleaning, and repair in difficult to access areas without damaging the underly ...

ABSTRACT: The objective of this proposal is improve the safety of employees working in or around compressed air delivery blast cleaning rooms (BCR) and blast cabinets (BC) by decreasing the levels of noise exposure to below the OSHA 8-hour Time-Weighted Average (TWA) while maintaining or decreasing ergonomic stress burdened by the operators and maintaining or increasing productivity. This resear ...

AVID will develop software to perform interactive conceptual design integration to enable improved estimates of performance, including weight and balance associated with early definition of subsystems layout and integration. The software will leverage AVID"s expertise in geometric modeling for conceptual design, along with the integration with multidisciplinary analyses. Three-dimensional visual ...

Modern combustion systems such as liquid rocket engines and gas turbines are characterized by high operating pressures and temperatures due to increased power-density. Thermal radiation has significant impact on both heat fluxes at the wall and on physical phenomena controlling the combustion process at these conditions. Coupling between radiation, turbulence and chemistry can have a large effect ...
