Table of Contents


Symposium Objectives

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 both a social and technical forum for personnel active in the field of mechanisms technology, as well as providing a source of information for others with an interest in this field. The symposium rotates annually between eight NASA centers and attracts papers and attendees internationally.


Symposium Location

The Radisson Hotel is the site for the technical sessions and several of the social activities. The Radisson is located on the waterfront in downtown Hampton. The telephone number for urgent messages to attendees during the symposium is (804) 727-9700; please mention the 30th Aerospace Mechanisms Symposium.


Symposium Activities

The technical and social activities planned provide an opportunity for attendees not only to become professionally acquainted, but also to develop personal contacts.


Early Registration

On Tuesday evening, May 14 from 7:00-9:00 PM, registration or check-in is in the pre-function area of the Radisson Hotel. Symposium materials, including the symposium proceedings and a computerized index of past AMS and European Symposium papers in Mac or PC format, will be available.


Symposium Banquet

On Wednesday, May 15, the principal social event of the symposium will be held at Shields Tavern in Williamsburg, VA. Shields Tavern was reconstructed in 1954 by COLONIAL Williamsburg on the site of the original Tavern built in the early 1700s. There will be an opportunity to walk around the Duke of Gloucester Street and view the colonial buildings (somewhat weather dependent) or socialize in Shields Tavern. A colonial dinner will be served followed by gambols (colonial games and entertainment). Bus transportation is provided between the hotel and the tavern.


Air Museum/Reception

On Thursday evening, May 16, a self-guided tour of the Virginia Air and Space Center (located one block from the Radisson) will be available from 5:00 – 6:30. This will be followed by an informal reception from 6:30 – 8:30 at Oyster Alley in the Radisson. The reception is open to all attendees and guests. Hors d’oeuvres and a no-host bar are provided. Also, the poster-session papers will be on display during the reception.


Langley Facilities Tour

On Friday afternoon, May 17, there is a special tour of NASA Langley Research Center facilities. Unique facilities include the Aircraft Landing Dynamics Facility, an operational wind tunnel, and the Impact Dynamics Research Facility. This tour is open to all attendees and guests. Buses depart from the hotel after lunch and return to the hotel after the tour (participants needing to go to the airport are taken directly from the tour to the airport). Please indicate when registering if you and your guests will participate. Also note that non-USA citizens are required to pre-register to participate in the tour.


Guest Activities

Tours of the local area are planned for Wednesday and Thursday. Please indicate your interest in theses activities when registering. Additional information will be sent to those who register in advance.


Authors’ Meetings

Presenting authors are required to join their Session Chair at a special breakfast on the day of their presentation at the time noted in the program schedule. This gathering gives the session participants an opportunity to meet one another and review the session arrangements. The Symposium Projectionist is available at this time to discuss presentation requirements.


Symposium Information


Registration

Advance registration is requested to facilitate planning. To register, return the registration card or submit a letter indicating name, mailing address, affiliation, e-mail address, and citizenship. Enclose the registration fee of $195 ($125 for students and educators, $25 for retirees (sessions only)). This fee covers all sessions, proceedings, break refreshments, reception, symposium banquet, and specified bus transportation. Guest tickets for the symposium social events are available at check-in.

Please note on the registration card or letter your interest in the NASA Langley Facilities Tour. Also indicate your guest’s interest in the NASA Tour, the social events, and Guests’ Program.

NOTE: Foreign nationals must register by April 15, 1996 to allow adequate processing time for the tour.

Checks are to be made payable to the 30th Aerospace Mechanisms Symposium and submitted with the registration card or letter to:

Ms. Gloria Carney
NASA Langley Research Center, MS 430
Hampton, Virginia 23681-0001
Tel: (804) 864-7152
Fax: (804) 864-7009

Please do not send purchase orders, foreign currency, or credit card charges. If registering at the symposium, cash, checks and money orders are accepted, but no credit cards. Checks/money orders must be drawn on a US bank in US dollars.

Registration also takes place at the Radisson Hotel on Tuesday evening, May 14, and each day of the symposium.


Hotel Reservations

A block of rooms is set aside at the symposium hotel. A special single or double rate of $74 (this is equal to the lodging allowable for the area) has been arranged. This rate will be available over the weekend. Attendees are responsible for making their own reservations directly with the hotel. Attendees must mention the 30th Aerospace Mechanisms Symposium to obtain the special rate. Requests for reservations must be made by April 23, 1996 to ensure obtaining the symposium rate. After this date, the hotel will honor the special rate on a space-available basis only. “No shows” are billed for the first night’s stay. All cancellations must be made no later than 6:00 PM on the day of arrival to avoid this charge.
The hotel address is:

Radisson Hotel Hampton
700 Settlers Landing Road
Hampton, Virginia 23669
(804) 727-9700


Transportation

Two airports serve the Hampton area: Norfolk International Airport and Newport News/Williamsburg International Airport. Complimentary hotel transportation is provided at both airports. Vans run to and from the airports by appointment only; they do not automatically go to the airports. Reservations must be made at least 72 hours in advance by calling (804) 727-9700 and asking for the Reservations Office.

Rental cars and taxis are available at each airport requiring approximately 25 minutes travel time to Hampton from either airport. Limousine service from the Norfolk International Airport to the Radisson is $20.


Dr. George Herzl Award

Each year a plaque is awarded to the author 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 Missiles & Space, a co-founder of the Aerospace Mechanisms Symposia.
