However, degradation in performance  occurred at higher amplitude profiles. As one of the trouble-shooting methods, a torque wrench was used  to record the required moment at the motor input interface. The test showed that the torque varied  significantly per revolution of motor. A probable cause for the variation is due to an internal alignment  problem at one of the drive component interfaces.  To isolate and locate the problem, the mechanical subassembly was disassembled and all the individual  components were inspected. No anomalies were discovered and all parts were machined within  tolerances as specified. The mechanical drive system was carefully reassembled with emphasis on even  and opposite torqueing of all bolt patterns and with careful inspection to assure that no contamination or  irregularities were present on the critical interfaces. The reassembled unit was then tested again to  determine torque consistency per motor revolution. The subsequent test showed a slightly increased  overall torque as compared to the previously fowest measured torque but with almost no variation per  revolution.  Once reassembled, verification tests of the FOS demonstrated the expected performance and system  safety. Figure 12 shows a response to a sinusoidal command input of 0.5 Hz at 5-degree amplitude. As  shown, the system tracked the roll command to within 3 percent of amplitude. Figure 13 shows the  encoder output from an excerpt of a Schroeder sweep command input. This demonstrates the new  capabilities as envisioned for the new FOS.  Integration and testing have verified system operation and safety. The system still needs to be evaluated  to characterize the performance over the full operational envelope. Validation testing with known inertias  397
is also required, and is underway to confirm system implementation and test techniques. Certification and  approval for wind-tunnel operation is being processed currently.

Conclusion  A new Forced Oscillation System (FOS) has been desigfied and built that will provide new capabilities  and flexibility for conducting dynamic derivative studies. The new design is based on a tracking principle  where a desired motion profile is achieved via a fast closed-loop positional controller. The motion profile  for the tracking system is numerically generated and thus not limited to sinusoidal motion. This approach  permits non-traditional profiles such as constant velocity and Schroeder sweeps. Also, the new system  permits changes in motion parameters including nominal offset angle, waveform and its associated  parameters such as amplitude and frequency. Most importantly, the changes may be made remotely  without halting the FOS and the tunnel.  System integration and testing has verified design intent and safe operation. Currently the FOS is being  validated for wind-tunnel operations and aerodynamic tests. Once complete, the system is a major  enhancement to forced oscillation studies. The productivity gain from the motion profile automation will  shorten the testing cycles needed for control surface and aircraft control algorithm development. The new  motion capabilities also will serve as a test bed for researchers to study and to potentially improve and/or  alter future forced oscillation testing techniques.  References  1.

NASA STI Program ... in Profile 

Since its founding, NASA has been dedicated   to the advancement of aeronautics and space  science. The NASA scientific and technical  information (STI) program plays a key part in helping NASA maintain this important role. 

The NASA STI program operates under the  auspices of the Agency Chief Information Officer.  It collects, organizes, provides for archiving, and  disseminates NASA’s STI. The NASA STI program provides access to the NASA  Aeronautics and Space Database and its public  interface, the NASA Tech nical Report Server,  thus providing one of the largest collections of  aeronautical and space science STI in the world.  Results are published in both non-NASA channels and by NASA in the NASA STI Report Series,  which includes the following report types: 

 TECHNICAL PUBLICATION. Reports of  completed research or a major significant  phase of research that present the results of NASA Programs and include extensive data  or theoretical analysis. Includes compila-  tions of significant scientific and technical data and information deemed to be of  continuing reference value. NASA counterpart of peer-reviewed formal professional papers but has less stringent limitations on  manuscript length and extent of graphic  presentations.    TECHNICAL MEMORANDUM.   Scientific and technical findings that are preliminary or of specialized interest,   e.g., quick release reports, working   papers, and bibliographies that contain minimal annotation. Does not contain  extensive analysis. 

 CONTRACTOR REPORT. Scientific and  technical findings by NASA-sponsored contractors and grantees.  CONFERENCE PUBLICATION.   Collected papers from scientific and  technical conferences, symposia, seminars,  or other meetings sponsored or  co-sponsored by NASA. 

 SPECIAL PUBLICATION. Scientific,  technical, or historical information from NASA programs, proj ects, and missions,  often concerned with subjects having  substantial public interest. 

 TECHNICAL TRANSLATION.   English-language translations of foreign scientific and technical material pertinent to   NASA’s mission.   Specialized services also include organizing  and publishing research results, distributing specialized research announcements and  feeds, providing help desk and personal search  support, and enabling data exchange services.

iii PREFACE  

The Aerospace Mechanisms Symposium (AMS) provides a unique forum for those active in the design, production and use of aerospace mechanisms. A major focus is the reporting of problems and solutions associated with the development and flight certification of new mechanisms. Organized by the Mechanisms Education Association, responsibility for hosting the AMS is shared  by the National Aeronautics and Space  Administration and Lockheed Martin Space Systems Company (LMSSC). Now in its 41 st  symposium, the AMS continues to be well attended, attracting participants from both the U.S. and abroad.   The 41 st AMS, hosted by the Jet Propulsion Laboratory (JPL) in Pasadena, California,  was held May 16, 17 and 18, 2012. During these three days, 38 papers were presented. Topics included gimbals and pos itioning mechanisms, comp onents such as  hinges and  motors, CubeSats, tribology, and Mars Science Laboratory mechanisms. Hardware displays during the supplier exhibit gave attendees an opportunity to meet with developers of current and future mechanism components.   This publication was prepared by the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration.
