This report selectively summarizes NASA Glenn Research Centerís research and technology accomplishments for fiscal year 2006. It comprises 198 short articles submitted by the staff scientists and engineers. The report is organized into three major sections: Programs and Projects, Research and Technology, 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, visit Glenn's Web site. For publicly available reports, visit the Glenn Technical Reports Server.
About the photographs:
Left: Setup for lighter weight, ironless motor that was used to determine static torque as a function of current and rotor angle. The motor's stator shown had a packing factor (percentage of the large rotor's air gap that is occupied by conductors) of only 10 percent. A new stator has been designed to increase the packing factor to 50 percent.
Center: International Space Station Astronaut Donald Pettit runs on a simulated zero-gravity treadmill on the enhanced Zero Gravity Locomotion Simulator (eZLS) in NASA Glenn Research Centerís Exercise Countermeasures Laboratory. The eZLS was developed collaboratively by Glenn, ZIN Technologies, and the Cleveland Clinicís Department of Biomedical Engineering. Glenn and ZIN also developed novel gravity-replacement load devices to keep a constant force on subjects exercising in simulated zero gravity, so that the effects of zero gravity on the human musculoskeletal system can be studied.
Right: To evaluate voice communications to and from a space-suited astronaut, a NASA engineer tests sound-pressure levels on an anthropomorphic mannequin inside a space shuttle hard upper torso and helmet.
