May 11 – 13, 2022

Hosted by NASA Johnson Space 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 symposium will be held virtually this year due to the ongoing COVID-19 Pandemic.


REGISTRATION – Advance registration is requested to facilitate planning and commitments. Please register on www.aeromechanisms.com. The registration fee is $200. Registrants will obtain access to the proceedings as soon as they are available. NOTE: If the registration payment is received after 11:59pm EDT (GMT-4) April 15, 2022 the registration fee is $250. Also, any registrations started but unpaid before this deadline will be also be revised to the late registration fee of $250. This fee covers all sessions, and early access to the proceedings, and note that it funds the work that the Mechanism Education Association does throughout the year for students.

Refund Policy – If a registration is cancelled, the Mechanisms Education Association will refund all fees paid less $50, if cancelled by May 1, 2022. After May 1, no refunds are given. Alternatively, a registration may be transferred to another employee if the original registrant cannot attend if the request for the transfer is done prior to the symposium by contacting our registration point of contact (Ron Mancini, MEA Treasurer).

  1. GEORGE HERZL AWARD – At each symposium, an award is given to the author(s) of the “Best Paper.” The award is based on paper content, presentation delivery, and visual aids. This award was established in honor of Dr. George Herzl of Lockheed Martin, a co-founder of the Aerospace Mechanisms Symposium.
  1. CHARLES COALE MERMORIAL SCHOLARSHIP – Each year the Mechanisms Education Association sponsors two high school First Robotics teams and two junior-high First Robotics teams in honor of Dr. Charles Coale of Lockheed Martin. Dr. Coale was the leader of the symposium for more than 20 years and had a special interest in helping children.

GRANTS – The Mechanisms Education Association may also provide an AMS attendance stipend to student authors.

MECHANISMS COURSES – On Thursday, May 5 through Tuesday, May 10, two separate courses will be offered. Registration for the Aerospace Mechanisms Symposium is not included in any class price.


Space Mechanisms Course (May 5 – 10)

Launchspace presents a special online course prior to the 46th Aerospace Mechanisms Symposium (AMS) in May 2022.

Fundamentals of Space Vehicle Mechanisms is a special edition of the internationally popular course on this topic. The instructor, Bill Purdy, 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, 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.

If you want to pick the right type of motor, lubrication or angular measurement device for your application then this is the right course. You will learn the fundamentals of space mechanisms from a leading mechanisms expert.  A unique benefit is the instructor’s sharing of his experience and lessons learned.

Register at:  Fundamentals of Space Vehicle Mechanisms 2022 – Launch Space


The special symposium price for this course is $695. 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.

Compliant Mechanisms Design (May 5 – 10)

Launchspace Training is providing a special edition of its new Compliant Mechanisms Design Course prior to the 2022 AMS Conference. This course has been developed for engineers working on mechanisms that are used to transfer or transform motion, force or energy in aerospace and other applications. Traditional rigid-body mechanisms consist of rigid links connected at movable joints. A compliant mechanism is a mechanism that gains at least some of its mobility from the deflection of flexible members rather than from movable joints only. This course focuses on the basics of compliant mechanisms, modeling and simulation, materials selection, failure prevention and design. Knowledge of such mechanisms is your link to advanced aerospace manufacturing techniques and applications.

The Active Response Gravity Offload System (ARGOS) is designed to simulate reduced gravity environments such as Lunar (1/6G), Martian (1/3G), or microgravity (0G). ARGOS achieves six degree of freedom motion using an active XYZ system similar to a bridge crane whereas rotational degrees of freedom are passively managed by a gimballing mechanism at the payload interface. ARGOS’ control system continuously tracks and offloads of a percentage of a human or robotic payload’s weight during a wide range of partial gravity and microgravity activities. The facility supports surface operation studies, suit and vehicle requirements development, suit and vehicle design evaluation, robotic development, mass handling studies, and crew training with both suited and shirt-sleeved subjects.
