44th AEROSPACE MECHANISMS SYMPOSIUM
May 16-18, 2018
Hosted by NASA Glenn Research Center and Lockheed Martin Space
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 Hilton Cleveland Downtown in Cleveland, Ohio 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 14-15, three separate courses will be offered in the same hotel as the AMS. Be sure to use the hotel booking link below when you make your hotel reservations. Registration for the Aerospace Mechanisms Symposium is not included in any class price.
Space Mechanisms Course (May 14-15)
Launchspace is providing a special edition of its internationally popular Space Vehicle 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 the many types of mechanisms are included for illustration. In addition, the mechanisms relationships and interfaces with other vehicle systems are explored. The course includes design and analysis examples to demonstrate principles involved in understanding how mechanisms should work and how design margins should be evaluated during the evolution of a program.

The special symposium price for this course is $895. Due to the special pricing (list price for this course is $1595), the textbook, “Space Vehicle Mechanisms: Elements of Successful Design”, edited by P.L. Conley, will not be provided but can be purchased commercially by attendees.
ESTL Space Tribology Course (May 14th and 15th)
The European Space Tribology Laboratory presents this course which draws heavily from experimental data generated during its 45 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/roller screws, 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 almost 40 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 (around 300 slides in total). The symposium price for the course is $1000 and a minimum of 25 delegate registrations is required for the class to be held.

Shape Memory Alloys – Designing Your Next Mechanism Workshop (May 15)
Sixty years after the discovery of shape memory alloys (SMAs), many actuation and structural applications using these materials have been conceived and developed. SMAs are a unique class of multifunctional materials that have the ability to recover large deformations and generate high stresses in response to thermal, mechanical and/or electromagnetic stimuli. These abilities have made them a viable option for actuation/structural systems in aerospace applications, amongst others. However, designing with SMAs is a paradigm shift from the conventional way we look at metals and mechanisms.
In this course, you will learn how the unique properties of SMAs can be applied to designing mechanisms and the associated benefits. Basic primer will be provided on what they are and why they work with examples of the most successful applications that have been imagined. Common design tool and properties-database will be discussed.
Price is $550 with breakfast included. Register in the registration module of the AMS.
CHECK-IN – On Tuesday evening, May 15, from 6:00-8:00 PM, check in and registration will be in the Hilton Cleveland Downtown Eliot’s Lounge located on the second floor. Symposium materials, including symposium proceedings, will be available, along with light refreshments.
RECEPTION – On Wednesday evening, May 16, a reception will be held in the Hilton Cleveland Downtown. Supplier and poster paper displays will be exhibited during the evening along with demonstrations by local high school FIRST Robotics teams. 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 17, the symposium dinner will be at the Rock and Roll Hall of Fame. The museum documents the entire history of rock and roll and is alive with the energy, passion and the spirit of music. The museum features seven floors, four theaters for films and ever-changing exhibits.
FACILITY TOURS – On Friday afternoon, May 18, there will be opportunities to go on a tour of NASA Glenn Research Center or NASA Plum Brook Station. The tours are open to all attendees and guests; space is limited on all tours so register early. Non-US citizens wishing to attend a tour must register for the symposium by March 15. Bus transportation will be provided.
GUEST ACTIVITIES – Cleveland is a major city in Ohio on the shores of Lake Erie. Landmarks dating to its days as a turn-of-the-20th-century manufacturing center include the Steamship William G. Mather, now part of the Great Lakes Science Center. It’s also known for the stately Cleveland Museum of Art. The popular Crawford Auto-Aviation Museum features an excellent private collection of antique cars and airplanes. Close by is Cedar Point amusement park, the roller coaster capital of the world. See Cleveland visitor’s guide at http://www.thisiscleveland.com/includes/content/docs/media/ovg.html
PRESENTERS’ MEETINGS – Presenting authors are required to attend a complimentary breakfast on the day of their presentation. (Note – only the presenters, not all authors of the paper.) This gathering gives the session participants an opportunity to meet their Session Chair and each other, and to review the session arrangements. The Symposium AV help will be available to discuss presentation requirements.
REGISTRATION – Advance registration is requested to facilitate planning and commitments. Please register on www.aeromechanisms.com. The registration fee is $750 ($350 for full-time professors, $300 for full-time students and $250 for retirees). Non-US citizens wishing to attend either of the tours must register by March 15. Late registration for the symposium may be done at the hotel on Tuesday evening, May 3, and each day of the symposium. NOTE: If the registration payment is received after 11:59pm EDT (GMT-4) April 13, 2018 the registration fee is $850 for all. Also, any registrations started but unpaid before this deadline will be also be revised to the late registration fee of $850 for all.
