A fully articul ated, soli d, parametric computer m odel of the flap a nd actuator system wa s constru cted with  all of the compone nts modele d in complete g eometrical detail  (Figure 7 ). The complete  model could be  moved thro ugh the full rang e of flap rotation and d eflections could b e introdu ced that rep resented therm al  expan sion of the flap supp ort be ams an d the mai n flap in bot h the longitudin al and verti cal direction s. By  constraining t he elem ents of the de sign model simila rly to the a ctual ha rdware, it was possible to verify   corre ct functioning of the d esign even with the main  compon ents i n a defle cted state before  any hard ware  or mockups had bee n constru cted. Essentially, the drive unit rotates about its mountin g axi s to maintain   the tange ncy of the pinio n gear and sector gear reg ardless of a ny shifts in th e locatio n of the flap hi nge  axis. Any such shifts cause the axis th rough  the center of the  arc path to no longer coin cide with th e flap  hinge  axis, which results in a small  cha nge in the normally p erpendicular angle of the  arc to fla p  connection. As the  flap moves un der this conditi on, the angle  betwe en th e arc and flap  will change  minutely and within the limi ts of the bearing capability. Using the computer design model, it was possibl e  to determi ne the actu al am ount of move ment at the b earin g with th e system i n a thermally def lected state  and verify that the movement wa s accepta ble. The  compute r model wa s also used to fin d and elimina te  sources of in terfere nce an d to verify a dequ ate asse mbly acce ss in the vehicl e. Finally, the com puter  model  proved  critical  for re al-time determination  of as-built comp onent lo catio ns in the vehi cle du ring the  initial integ ration of  the fla ps and actuators. Witho ut the a rticulated 3D model, it woul d have been very  difficult to pro perly align th e parts of the mech anism.

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 import ant 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 Technical 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, wh ich 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 counter - part 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, projects, and missions,  often concerned with subjects having  substantial public interest.  

• TECHNICAL TRANSLATION.   English -language translations of foreign  scientific and tech nical 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 excha nge 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 40 th  symposium, the AMS continues to be well attended, attracting participants from both the U.S. and abroad.    The 40 th AMS, hoste d by the Kennedy Space Center  (KSC) in Cocoa Beach, Florida,  was held May 12, 13 and 14, 2010. During these three days, 38 papers were presented.  Topics included gimbals  and positioning mechanisms, CubeSats , actuators , Mars  rovers , and Space Station mechanisms . Hardware displays during the supplier exhibit  gave attendees an opportunity to meet with developers of current and future mechanism components.
