This report selectively summarizes NASA Glenn Research Center’s research and technology accomplishments for fiscal year 2002. It comprises 166 short articles submitted by the staff scientists and engineers. The report is organized into five major sections: Aeronautics, Research and Technology, Space, Engineering and Technical Services, and Commercial Technology. A table of contents and author index have been developed to assist readers in finding articles of special interest. This report is not intended to be a comprehensive summary of all the research and technology work done over the past fiscal year. Most of the work is reported in Glenn-published technical reports, journal articles, and presentations prepared by Glenn staff and contractors. In addition, university grants have enabled faculty members and graduate students to engage in sponsored research that is reported at technical meetings or in journal articles. For each article in this report, a Glenn contact person has been identified, and where possible, a reference document is listed so that additional information can be easily obtained. The diversity of topics attests to the breadth of research and technology being pursued and to the skill mix of the staff that makes it possible. For more information about research at Glenn, visit us on the World Wide Web. For publicly available reports, visit the Glenn Technical Report Server.
About the photographs (from left to right):
The flutter analysis code TURBO was used to calculate the observed flutter of this forward-swept experimental fan, which was designed to reduce noise.
This utility vehicle was tested with ultracapacitors instead of lead acid batteries. Ultracapacitors require no maintenance, have unlimited life, and can be charged in minutes rather than hours.
NASA's Ultra-Efficient Engine Technology project is developing revolutionary turbine engine propulsion technologies that will enable the development of future vehicles over a wide range of flight speeds from subsonic to supersonic. The GE90 engine shown here incorporated technologies from previous NASA research; new technologies being developed under this project are expected to be incorporated into future engines like the GE90.
The sample processing unit shown here is one of the two main pieces of flight hardware that were assembled and tested for the Coarsening in Solid-Liquid Mixtures-2 (CSLM-2) experiment-a materials science space flight experiment whose purpose is to investigate the kinetics of competitive particle growth within a liquid matrix.
