Baltimore, Maryland

May 14-16, 2014

Hosted by

NASA Goddard Space Flight Center and Lockheed Martin Space Systems Company

Organized by the Mechanisms Education Association


This symposium is concerned with the problems of design, fabrication, test, and operational use of aerospace mechanisms. Emphasis is on hardware developments. The symposium provides a social and technical forum for personnel active in the field of mechanisms technology, as well as providing a source of information for others interested in this field. The symposium rotates among eight NASA Centers and attracts papers and attendees from all over the world.


The Hyatt Regency in Baltimore, Maryland is the site for all technical sessions.


The planned technical and social activities provide an opportunity for attendees to become professionally and personally acquainted. Dress attire is business casual unless otherwise noted.

MECHANISMS COURSES – On Monday and Tuesday, May 12-13, three separate courses will be offered in the same hotel as the AMS. Be sure to mention the AMS special room rate when you make your Hyatt reservations. Registration for the Aerospace Mechanisms Symposium is not included in either class price.


Space Mechanisms Course (May 12-13)

Launchspace is providing a Special Edition of its popular space mechanisms course. This course explores the technologies required for successful space mechanisms design and offers a detailed look at many of the key components common to most mechanisms. The materials necessary to achieve high performance are discussed. Examples of some of the many types of mechanisms will be included for illustration. In addition, the mechanisms relationship and interface with other vehicle systems will be explored. The course includes design and analysis examples to demonstrate the principles involved in understanding how mechanisms should work, and how design margins should be evaluated during the evolution of a program.

To register, go to www.launchspace.com and register for course 1135SE. The Symposium price for this course is $695. A minimum of 30 attendees is required for this class to be held. Due to the special pricing (list price for this course is $1595), the textbook will not be provided as indicated in the catalog course description. The textbook, Space Vehicle Mechanisms: Elements of Successful Design, edited by P.L. Conley, is available for an additional $175, and may be ordered upon registration.

PTC Mechanisms Design Course (May 12)

In this course, you will learn about creating mechanism connections, configuring the mechanism model, creating a kinematic analysis, and evaluating results. Mechanism Design using Creo Parametric is designed for experienced users who want to add motion to their models by creating mechanism connections and servo motors. In Creo Parametric you can add motion to your models using the standard mechanism functionality, often referred to as the Mechanism Design Extension (MDX). These topics will enable you to simulate the range of motion between components in your moving assemblies, create gear connections that simulate the gear ratios, create Cam connections that enable Creo Parametric parts to “push” other parts they come into contact with, and check for collisions between moving components. After completing this course, you will be prepared to work on mechanism designs using Creo Parametric Mechanism Design. The Symposium price for this course is $490. The course is limited to 24 attendees due to computer availability (attendees will practice what they learn during the class), minimum of 6. Register by sending an email to Learning@ptc.com with the subject line

‘Registration for AMS; PTC Mechanism Design Class – May 12th’.

ESTL Space Tribology Course (May 13)

The European Space Tribology Laboratory presents this course which draws heavily from experimental data generated during its 40+ years as Europe’s independent center of excellence for space tribology. Attendees will receive a comprehensive overview of the many issues relating to friction, lubrication and wear of spacecraft mechanisms, presented in 4 parts:

Fundamentals of Tribology – in which tribological concepts are introduced and the special considerations for space and vacuum tribology highlighted.

Tribo-component Design and Performance – in which an overview of the different types, characteristics and performances of tribo-components (ball bearings, gears, plain and ball/rollerscrews, etc.) used in spacecraft applications is provided. This includes a detailed presentation of considerations for design, selection and load capacity verification of ball bearings for space applications.

Lubrication of Spacecraft Components – in which the application-driven considerations for selection of fluid and dry (solid) lubricants are provided. This part includes the considerations and typical performances of dry (solid) and fluid lubricants, respectively. Some practical issues concerning application, handling and preloading of ball bearings are also presented.

Lessons Learned – presenting a selection of the (sometimes painful!) lessons learned on various programs.

Summarizing test data not widely accessible outside Europe the course, whose two presenters have a combined 50+ years of space tribological experience, will be valuable both for younger engineers entering the industry and for the more experienced who may wish to refresh or challenge their tribological understanding. Attendees will receive personal paper and electronic format copies of presentation handouts (almost 300 slides in total). The symposium price for the course is $750 and a minimum of 25 delegate registrations is required for the class to be held. Register via the ESR website:   http://www.esrtechnology.com/centres/estl/Pages/default.aspx.

CHECK-IN – On Tuesday evening, May 13, from 6:00-8:30 PM, check in and registration will be in the Pisces Room, 15th floor in the Hyatt Regency. Symposium materials, including symposium proceedings, will be available, along with light refreshments.

RECEPTION – On Wednesday evening, May 14, a reception will be held in the Hyatt Regency’s Atrium. Supplier and poster paper displays will be exhibited during the evening along with demonstrations by local high school FIRST Robotics teams and a display of 4-Hers working in robotics and aerospace projects. A light buffet dinner will be served. The exhibits will be open for the enjoyment of all attendees and guests.

SYMPOSIUM BANQUET – On Thursday evening, May 15, the symposium dinner will be in the National Aquarium, a short one-block walk from the Hyatt Regency. (A shuttle can be provided for the disabled or those that need assistance.) The National Aquarium, voted one of the best aquariums in the U.S., boasts the Blacktip Shark Reef, jelly fish invasion, and the Animal Planet Australia exhibits and more than 17,000 fish, amphibians, reptiles, birds, mammals and invertebrates. The Symposium has booked the entire aquarium for an exciting evening of socializing among the exhibits along with a memorable dining experience. For more information on the aquarium exhibits, visit www.aqua.org.

FACILITIES TOUR – On Friday afternoon, May 16, there will be an exclusive tour of the NASA Goddard facility, which will include the large clean room with JWST mirror segments and integrated science instrument module. The Visitor Center displays will also be available to tour. The tour is open to all attendees and guests. Buses depart from the hotel, stop at BWI airport, and then return to the hotel.
