32. GTTC Working Groups Established to address technical needs in aerospace ground testing community Provide forum for discussion and the development of solutions and standardization Not a continuous activity - each working group identifies a specific goal or product that will be developed Typically an AIAA Standard, Guide, Recommended Practice, or Special Project Report Anticipate each working group to exist for 4-10 years Must be chaired by GTTC member Membership includes both GTTC and non-GTTC and non-AIAA Meetings held to coincide with GTTC meetings “Lessons Learned” developed to provide “How To” guidelines for new working groups

33. Working Group Development Working Groups work together to integrate activities: Share lessons learned and coordinate meeting schedules Working Group development guidelines Showcased development and products Working Groups are continually being established Current Working Groups: Flow Quality Thrust Stand (disbanded) Wind Tunnel Nomenclature Dynamic Wind Tunnel Testing (disbanded)

34. Recent GTTC Working GroupProducts Internal Balances Technology and Calibration Working Group AIAA Recommended Practice for Calibration and Use of Internal Strain-Gage Balances with Application to Wind Tunnel Testing, (R-091-2003) Test Processes Working Group AIAA Recommended Practice for Wind Tunnel Testing — Part 1 (R-092-1-2003) AIAA Recommended Practice for Wind Tunnel Testing — Part 2 (R-092-2-2003) Wind Tunnel Calibration Methodology Working Group AIAA Recommended Practice for the Calibration of Subsonic and Transonic Wind Tunnels (R-093-2003) Other Products: Assessment of Experimental Uncertainty with Application to Wind Tunnel Testing (S-071A-1999) AIAA Guide to Assessing Experimental Uncertainty - Supplement to S-071A-1999 (G-045-2003)

37. Focus Groups Operate independently from the GTTC No requirement of shared membership (although allowed and encouraged) No requirement to co-locate meetings with the GTTC (although allowed) Independent charters Primary function is sharing of information within GT community Free exchange of ideas, lessons learned, technical knowledge exchange Meet two times per year at a member organizations site Allows for tours and sharing of information via presentations and informal papers Information is kept within the Focus Group, but may be made available to the GTTC Communications with GTTC through liaisons Representatives welcome to attend the GTTC meetings Current Focus Groups: Turbine Engine Test Working Group Space Simulation Working Group U.S. Industry Test Facilities Working Group

38. Focus Groups (cont) May be called on to support GTTC activities Conference sessions, working groups, etc If a Focus Group wants to produce a formal deliverable (standard, recommended practice, guide, or white paper) Formal WG can be established under the GTTC Work can be completed by the Focus Group Approval of any deliverable must be granted by the GTTC Formation Similar to the formation of a Working Group Establish need, core membership set Charter must be drafted and presented GTTC membership will vote on sponsorship Sponsorship reviewed by the GTTC every four years (or sooner if required) Focus Group can be dropped from the GTTC

39. GTTC Member Expectations Stay in communication: Attend your appropriate Subcommittee/Working Group meetings (reference matrix in roster workbook) Notify TC and Subcommittee Chairs if you are unable to attend Notify GTTC Secretary of changes in phone, email, etc. Participate actively: In at least three Subcommittees (again, primary + two task) Be a major contributor/leader of at least one of these activities How do you select you areas of participation? Go to meetings… Subcommittees (all or most) to find out what goes Working groups that have some interest to you JUMP RIGHT IN! Don’t expect to wait until you are comfortable!

40. GTTC Member Expectations(cont) Provide annual support as: Conference Session Chair Reviewer for Outstanding Papers / Best Paper GTTC Mentor Contributor to GTTC Newsletter Contributor to AIAA Highlights article When the opportunity arises: Submit TC nominations Invite technical papers or plan technical sessions Submit Ground Testing Award nominations
