N/A

Manual welding operations remain totally dependent on the instincts of the operator and the operator's ability to collect information through normal sight and sound. The proposed innovation will apply modern data presentation technology to enhance the welder's perception of the welding situation. This "enhanced reality" will improve the quality of data available during a manual weld, thus improvin ...

The focus of the Phase I work proposed herein is the preliminary design of a Coherent Phase Cavitation Monitoring System (CPCMS) for turbomachinery. Cavitation is the process of boiling water which occurs when local hydrodynamic pressures in the areas of accelerated flow drop below the vapor pressure of the fluid. When cavitation occurs on the turbopumps for liquid rocket engine propulsion systems ...

N/A

Hybrid rocket propulsion systems are attractive because they use a single fluid (LOX), and avoid the high injector part count of dual fluid propulsion systems. However, the hole drilling costs associated with fabricating the injectors can be large, and the small holes that are desirable to achieve optimum atomization can be either too expensive or impossible to produce. We propose a novel injector ...

The proposed effort covers the engineering aspects of a magnetic field source to be used in a table-top demonstrator of magnetic refrigeration. A prototype magnetic field source, based on the Halbach or "magic-ring" concept, will be designed, constructed and tested in the Phase I effort. The proposed device is based on an innovative concept that is simpler than current magic-ring configurations. ...

N/A

The objective of this proposal is to design and implement a set of tools that will facilitate the parallel processor software development process. This toolset will be graphically oriented to promote extensive visualization of the various phases of software development. Visualization will include the ability to view and edit source code, manage and control executable modules, edit and display dist ...

Stability of the optical properties of materials in the space environment is a limiting technology in the development and operation of spacecraft. The complex space environment can damage exposed materials including thermal control surfaces. The thermal radiative properties of these materials are critical to maintaining spacecraft thermal control. Accurately measuring these properties is a difficu ...

We propose to develop an innovative class of electrically conductive thermal control coatings (both white and black). This will be accomplished through the use of current state-of-the-art organo-metallic, sol-gel techniques and the use of state-of-the-art solid state physics, chemical sciences and computer modeling techniques. The proposed effort will explore the feasibility to produce coatings th ...
