GSWG History Established Space Inflatables (later Gossamer

Spacecraft) Working Group (GSWG) in April 1998 Group has met formally every year at AIAA SDM and informally

(~twice/year)

John and Dave are conscripted at the 2001 SDM conference and work on formalization of the GSTC

The GSWG developed the GSTC charter and TAC presentation for the August 2001 TAC review

TAC informed the GSWG in October 2001 that 65 of the 66 TCs had approved our formation and thought STRTC would also…but they didn’t

The GSWG met with the STRTC April 22, 2002 and...

GSTC Future Direction

Make formal presentation to the AIAA TAC New Initiatives Subcommittee at the Modeling and Simulation Conference and Exhibit 5 - 8 Aug 2002 Monterey, California

Become formally established as the GSTC Formalize charter and participants Address items in the charter through

subcommittees Establish links to other AIAA TCs

GSTC 5

The GSTC Charter Draft charter is released Please provide comments! Looking for comments to

foster improvements in effectiveness Looking for an electronic home (e-mail for now until we

establish a website) We need to establish subcommittees and increase

activities

GSTC 11

What is a Gossamer Spacecraft?

Examples: Antennas Solar Sails Solar Arrays Telescopes Habitats Solar concentrators Sunshades ED&L Systems Decoys Rovers Radiators Space suits

Technical Focus: Packing &

deployment methods & effects

Rigidization methods & materials

Membrane technology

Highly integrated, multi-functional components

Mission concept development

Non-linear, large deflection analysis

Gossamer spacecraft are systems that

have high deployed to

packed volume ratios

and are extremely low

in mass.

AIAA TAC

GSTC 12

Why a Gossamer Spacecraft TC

Unique area that is rapidly growing in interest within the space community

No specific forum exists for Gossamer Spacecraft to promote: Technology development User education Space community awareness Cross-discipline interaction

Space systems effectiveness will increase through gossamer spacecraft advancement & application

Special forum to foster discussion on interrelated issues that are the heart of making a Gossamer system

The topic is emerging and is often shunned by various disciplines…needs its own forum to mature

AIAA TAC

GSTC 13

Committee Goals To establish Gossamer Spacecraft expertise within the AIAA

Provide a technical resource for AIAA Attract new members

To promote technical interchange between members of various disciplines within the space community Provide a forum for communication between technology

developers and mission planners Provide leadership & direction to the community Promote technical interchange with other AIAA TCs, AIAA

members, & other professional organizations Advance the understanding of Gossamer spacecraft within the

space community Sponsor conferences & sessions Technical publications (papers/journals/books) Student participation & activities Workshops & Website presentations

AIAA TAC

GSTC 14

Communications Plan Request a liaison from other

TCs attend one GSTC meeting per year and be include on “friends of GSTC list” (most will have opportunity at SDM Conf.)

Copy meeting minutes to other TCs and request feedback

Make presentations to other TCs at their meetings

Write Bi-annual interface summaries for inclusion with minutes

AIAA TCs the GSTC should interact with heavily: Structures Adaptive Structures Materials Space Systems Aerodynamic Decelerators Balloon Systems LTA

Communications are critical to meet our goals!

GSTC 15

Proposed Scope of The Gossamer Spacecraft Technical Committee

The purpose of Gossamer Spacecraft Technical Committee (GSTC) is to develop and promote the science and technology of analyzing, designing, manufacturing, and evaluating the materials and components that are unique to gossamer inflatable, deployable, and membrane Spacecraft. This will be accomplished by providing a forum for technical interchange, by providing leadership and a collective informed decision making body (which will include industry, academia, and government). The GSTC will also encourage the development and dissemination of technical information, promote technology awareness through outreach activities such as workshops and website development, assist in the development of industry standards, and foster technology awareness through relations with other TCs and professional organizations.

Summary of Past Events Industry workshops:

Space Inflatables Technology National Workshops October, 1996 (150+ attendees) May, 1998 (200+ attendees)

Gossamer Spacecraft Initiative Workshop, Oct 1999 (300+ attendees)

DoD Space Technology Alliance Workshops, 1999 (NRO) & 2000 (WPAFB)

Many system specific workshops (Solar Sails 1997, 2001 - Telescopes 1999, 2000, etc.)

Several Conferences have sponsored sessions specific to gossamer spacecraft 39th & 40th AIAA SDM 1998/1999 — 2 sessions 41st AIAA SDM 2000 — 5 sessions (Forum) 42nd AIAA SDM 2001 — 8 sessions (Forum) 43nd AIAA SDM 2002 — 9 sessions (Forum) Several other conferences - 1 or 2 sessions

Summary of Past Events Established Space Inflatables (later Gossamer

Spacecraft) Working Group (GSWG) in April 1998 Group has met formally every year and informally

twice/year Approximately 50 dedicated to group with another 150

showing strong interest GSS WG published an AIAA book on Gossamer

Spacecraft in 2001 Strong government support at DoD and NASA

(included in strategic plans) Many Government Gossamer solicitations: Gossamer

Spacecraft NRA, CETDP NRA, SBIRs, NMP, ROSS NRA, etc.

Recommendation

Based On Current Gossamer related activities Current Organization Has Solid Foundation

Membership Industry Support Has Direction/Leadership

Has Successfully Demonstrated That It Can Function As A TC Meetings Several Conference Activities Organized Planning

Benefits To AIAA Technical Support Increased Membership Conference Development

Recommend That The Gossamer Spacecraft Technical Committee Be Established
