This report selectively summarizes NASA Glenn Research Centerís research and technology accomplishments for fiscal year 2003. It comprises 170 short articles submitted by the staff scientists and engineers. The report is organized into four major sections: Aeronautics, Research and Technology, Space, and Engineering and Technical Services. 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 Reports Server.
About the photographs:
Top: Solar-powered Venus airplane shown over a computer-generated radar image of the surface of Venus. The surfaces of the wing and the horizontal tail are covered with solar cells. Artistís conception by Terence K. Condrich of InDyne, Inc.
Center: A prototype of the Hydrodynamic Focusing Bioreactor--Space (HFB-S) is free-floating inside NASA's KC-135 Reduced Gravity Research Aircraft. The HFB-S is being developed for possible use on the International Space Station to grow tissue cultures in microgravity.
Bottom left: NASAís Ultra-Efficient Engine Technology Project is developing and delivering revolutionary gas turbine propulsion technologies for increased performance and efficiency at the component or subsystem level, relying on strategic, cost-sharing partnerships and opportunities with the aerospace industry and other Government agencies for technology demonstration, maturation, and application. The engine shown here is a supersonic engine.
Bottom right: Fuel cells tested in conjunction with ultracapacitors as part of NASAís Hybrid Power Management (HPM) Programís emphasis in exploring new power applications.
