Under this effort, Sentient will develop mixed-EHL models to predict the performance of fluid film bearings for submarine applications. The models will consider critical design and operational parameters such as component geometry and surface finish, start up and shut down speeds/loads, and lubrication properties to predict torque, film thickness, and associated wear/efficiency. The result will be ...

Next-generation high-performance computers (HPCs) are built as massively parallel systems where the parallelism exists at many levels. These systems are a collection of nodes all working together. Each node generally contains more than one processor and each processor contains multiple cores. Managing and efficiently utilizing the different parallelism in such a system is a complex task. Furth ...

This proposed research for Phase II consideration involves the growth of AlInN/GaN heterostructure field effect transistors (HFET) on bulk GaN substrates. By combining a homoepitaxial substrate for the growth of the heterostructures with the lattice-matching ability of the AlInN alloy, it is expected that the defect density in the eventual HFETs can be reduced significantally, ultimately improvin ...

ABSTRACT: High-performance computing (HPC) programmers and domain experts, such as those in the Air Force's research divisions, develop solvers for a wide variety of application areas such as modeling next generation aircraft and weapons designs and advanced image processing analysis. When developing software for HPC systems, the programmer should not spend the majority of their time optimiz ...

ABSTRACT: Optical control of RF-signal transmission presents an attractive avenue for processing and transmitting RF information using various optical components, as opposed to electronic control, where metallic wires/cables are required. On a macroscopic scale, optical fibers offer low transmission losses, and hence are suitable for the distribution of control signals over long distances for lar ...

In this SBIR effort we will design (Phase I) and demonstrate (Phase II) an integrated silicon electronic-photonic upconversion receiver that when used with our photonic backend will allow for a highly sensitive, real-time, and economical millimeter wave (mmW) imaging system. The development of this chip leverages recent progress in CMOS and SiGe HBT high speed analog circuit design and integrates ...

ABSTRACT: Accudyne proposes a SBIR program to develop an automated material placement process for aircraft radomes and demonstrate it by forming quartz cynate ester fabric over an existing radome tool. The process employs computer simulations to model the forming process and compute a 2D fabric pattern as well as a four degrees of motion machine to form the fabric over the curved radome tool. T ...

ABSTRACT: This project will investigate the feasibility of an integrated multilevel system for protecting space assets from system hardware and firmware exploitation. The overall strategy is to provide greater collective system protection as a whole than would otherwise be available from the sum of the independent defenses. Rather than relying on a loose-knit collection of isolated point solution ...

ABSTRACT: American Semiconductor will develop and demonstrate structural integration of a conformal load bearing antenna structure (CLAS). Future aircraft will incorporate distributed electronics, sensors, and flight control transducers directly into the composite airframe. For near-term Air Force applications, adding RF electronics into the CLAS will improve the performance of a wide variety o ...

The overall goal of this project is to develop an optimized surface texture process in order to maximize the efficiency of rolling/sliding contacts such as gears. Development of this high efficiency, rolling/sliding surface will be guided by Sentient's unique combination of modeling capabilities in the area of mixed-EHL contacts, scuffing, and contact fatigue life prediction. Phase I wi ...
