ACX proposes to develop durable and reliable conformal geometry actuator packages. These packages will have the ability to operate as linear actuators for motion control applications as well as to conform to structures with curved surfaces for applications requiring induced strain actuation. These packages provide a protective skin offering electrical isolation, and provide a means for integration ...

This Phase I project has two primary objectives. The first objective is to evaluate the feasibility of a fully ion implanted fabrication process based on the heterodimensional 2-D MESFET. The new device, the 2-D JFET, will have p+ ion implanted sidegates which laterally modulate a thin, highly doped n-type conducting channel. The 2-D JFET should have excellent high speed, low power characteristics ...

AeroSoft, Inc. proposes to develop, incorporate and validate transition and anisotropic turbulence models for improving the low-Reynolds number predictions for high-lift airfoil configurations. The turbulence-modeling package will use Menter's two equati

Existing materials used for marine cable connectors each have drawbacks in terms of cost or performance. Alden Products Company proposes a program to develop a family of cable connectors and adapters that lower the present cost/performance barrier in two ways; through the use of alternative materials and through new manufacturing methods using the existing materials. The main goals of P ...

Silicon avalanche photodiodes are among the most sensitive optical detectors available today. It 11as been shown that large area APDs are potentially an excellent alternative to photomultiplier tubes (PMTs) in applications such as LIDAR, nuclear medicine, physics research and nuclear radiation measurement instrumentation. They can offer improved performance based on their compact size, solid state ...

The proposed prototype Operational Trainer for the FFG-7 AAW Combat System will provide the US Navy with a means for training the FFG-7 AAW combat team to operate their equipment in condition 1 watch stations. Each watch station will be provided with the ability to train as they fight by allowing continuous on-board AAW training that includes all elements of the combat system with interactions as ...

New power semiconductor device performance is limited by cooling because high heat-flux cooling systems have not matched their increased power density. Therefore, real designs rarely achieve device ratings. American Superconductor (ASC) demonstrated CryoPower+, which cools a variety of power MOSFET topologies by direct immersion in coolants from 77-300K, with boiling where appropriate. CryoPower ( ...

Attachment areas in the regions of rotating components of gas turbine engines degrade due to fretting wear and fatigue. Plasma sprayed coatings are often used to protect these regions. A thin, dense, Ti(C, N) composite coating based on sol-gel process is proposed. The simple, cost-effective sol-gel process will coat complex shapes and will provide superior performance against fretting wear. Di ...

The objective of the proposed Phase I work is to demonstrate the feasibility of using the Choi-Williams distribution to estimate the time ¿ frequency distribution of transients of interest to the IUSS. The specific objectives are to develop a metric for IUSS images and to show that the Choi-Williams distribution of these images may be used for classification. The Choi-Williams distribution is ...

In this six-month Phase I program, ANRO Engineering, Inc. proposes to investigate the properties of compact, low-cost, two-dimensional fiber optic and integrated optic Rotman lenses for application to wideband, multi-function RF/microwave/millimeter wave antenna (MFA) systems. The photonic Rotman lens will enable the reception and transmission of simultaneous, multiple frequency, independent ...
