Not Available This program proposes a fresh look at the tape-wrapped carbon-phenolic (TWCP) fabrication process used in the manufacture of reentry body heatshields with the objective of finding their variations to the existing processing or new processes which will result in significantly reduced… More

Not Available A new optical fiber sensor technology for high-temperature strain measurement is proposed. This technology is based on a sensor consisting of Bragg gratings etched into silica channel waveguides. The transduction mechanism for this sensor follows the conc

Innovation in key technology areas will provide the dramatic advances needed for small- to mid-sized space-based flywheel energy storage systems. Our vision for this work is based on our understanding of high-speed machinery and our background in similarly sized flywheel systems. Based on this… More

DESCRIPTION (Verbatim from the Applicant's Abstract): A small, intravascular catheter pump providing adequate output, good blood compatibility, and high reliability is being designed for use as a cardiac-assist pump in the operating room or interventional cardiology laboratory.… More

Bearing failures are among the most costly, troublesome forms of breakdowns on mission critical machines within the Navy. A failed bearing causes extended downtime and high repair costs, particularly when secondary machine damage occurs. Magnetic chipdetectors, simple vibration monitoring devices,… More

"Condition Based Maintenance (CBM) has become the Navy's overriding operating philosophy aimed at reducing life-cycle costs while maintaining operational readiness by decreasing maintenance requirements and operating with reduced manpower. To support theCBM philosophy, the Navy needs to be able to… More

"A reliable bearing system is key to the success of any flywheel energy storage system. Thebearings must consume little power and provide proper stiffness and damping properties so thatthe rotor can achieve stable high-speed operation without critical speed or resonance problems.Development of an… More

This project will provide the basis for development of a new family of inductive power harvesters that use machine vibration and mechanical resonance to amplify oscillatory motion at the magnetic juncture. The Phase I base program involves the design,manufacture and test an initial power harvester,… More

DESCRIPTION (provided by applicant): Limb-shortening deformities and bone segmental defects remain among the most difficult challenges faced by patients and orthopaedists. Traditional techniques to correct these problems rely primarily on transverse pins or wires, which are subject to pain, scars,… More

Description (provided by applicant): The goal of this Phase II project is to demonstrate the prototype of a fully implantable rotary ventricular assist device (VAD). This pump utilizes the advanced three-dimensional magnetic suspension for the rotor demonstrated during Phase I. This bearing… More

DESCRIPTION (provided by applicant): An "Inherently Controlled Bearing" (ICB) concept has been demonstrated in a magnetically suspended rotary blood pump intended for use as a permanently implanted ventricular assist device (VAD). The ICB eliminates not only position sensors but also active… More

DESCRIPTION (provided by applicant): The goal of this Phase II program is to develop and demonstrate a compact, highly accurate, and easy-to-use diagnostic system for monitoring the "health" of implanted rotary blood pumps. Based on promising results from Phase I, this blood pump diagnostic… More

The F-35 VSTOL configuration includes a lift fan driven by a long, slender hollow shaft that operates at high speeds. The shaft spins whenever the aircraft's engine runs, and transmits considerable horsepower when the lift fan is activated. In additionto being a key element in the aircraft's drive… More
