AIAA BOD Presentation/ John Evans John Evans gave an update on the AIAA Governance Redesign Initiative Under the new structure a 9 member BOD will have the power to change the By-Laws. The BOD will be elected by a House of Delegates, which is elected by the general membership from different constituencies. Concerns were raised by the TC members regarding the increased power of the AIAA BOD in this new structure and what the new By-Laws will include. The concept of a BOD elected by a House of Delegates, who are elected by the general membership was considered reasonable but the details need to be presented to the AIAA membership before they are required to vote on this issue.

AIAA Updates: ASG, Rob Vermeland/AIAA Governance Update Rob Vermeland's presentation is attached It was reported that there were 4000 at SciTech AIAA finances have improved over the last year and new initiatives are now possible It was suggested that people should be given an incentive to vote, such as free registration to the next SciTech meeting Members of the TC emphasized the importnace of engaing the membership in the AIAA decision making process 2017 Aviation meeting will be in Denver A representative is needed at the Aviation 2016 meeting to represent the TC at the organizational meeting for Aviation 2017. Concerns were raised about the small rooms at the conference

Approval of Aviation 2015 TC meeting minutes The minutes of the TC meeting at AVIATION 2015 were approved

Awards Sub-Committee

AIAA Aeroacoustics Award is based on Scientific Merit and Engineering Contributions Relevance of Work to the Scope of the Award AIAA Service

Aeroacoustics Award Process Nominations: via AIAA with eligibility and nomination requirements Aeroacoustics Award Subcommittee (AAS) for the 2015 consisted of 6 members from academia, government and industry. All are AIAA members and three are former recipients of the Aeroacoustics Award. The AAS Chair has a history of evaluations and selections results for 3 years, which were made available to the AAS members to ensure consistency from year to year. For 2015, there are 8 full nominations including carryovers. Decision must be made and submitted to AIAA Director of Aeronautics by 4/1/2015. Nomination files have been reviewed by the AAS and discussed in a conference call last November. AAS has established that we have an award-worthy pool of candidates. Final decision will be made after a second conference call scheduled for mid-January. Discuss the role of the Nomination Sub Committee: Should the members sponsor nominees? At the present time this decision was left to the individual committee members. Concerns were raised about the process for choosing the members of the awards subcommittee. A working group (Stewart Glegg (chair), Phil Morris, Krish Ahuja and Dennis McLaughlan) was set up to draft alternate proposals on the selection process for the awards committee membership, for discussion at the TC meeting in Lyon.

Education Sub-Committee

Student Paper Award: Process Students Register For Competition When Submitting Extended Abstracts Entrants Must Be Students As Of The Previous Year’s (2014) Aeroacoustics Conference Many Students Are Affiliated With Industry, National Labs Etc. – Open Issue Full time versus part time students, decision not to act Written Paper Submitted Approximately Two Weeks Prior To The Conference Manuscript Submission Deadline, this requirement weeds out many papers Allows For Detailed Review Of The Written Papers Prior To The Conference Greatly Reduces The Number Of Competitors Oral Presentations Review Committee Members Attend Presentations To Evaluate Review Committee Meets After All Student Presentations To Determine Overall Winner

Student Paper Award: Evaluation Aeroacoustics 2015 Statistics 27 abstracts submitted, 9 final papers, top 4 finalists for presentation portion Student Papers Are Scheduled On First 3 Days Of The Conference – All papers Mon.-Wed. morning Evaluation based on written paper and oral presentation, Thanks to everyone who reviewed papers! Need Volunteers – Thanks to presentation review committee! Written Paper Criteria (35 Points) Relevance of Topic 2 Understanding of Topic 3 Technical Content and Derivations 10 Quality & Originality of Research Grammar and Prose 8 Completeness Oral Presentation Criteria (65 Points) Clarity 10 Poise Time Quality of Charts/Presentation 20 Answers to Questions 15

Student Paper Award Concerns were raised about the timing of the student paper award announcement at the AVIATION conference, and the invitation of the student to the banquet. This issue should be on the agenda at the TC meeting in Lyon. At request needs to be made to Jim Keenan for funds to cover the student paper award

Liaison Report – Steven Rizzi

Array Methods Panel Session planned Aeroacoustics 2016 The Virtual Acoustic Simulation Technology for Community Noise (VASTCON) Technical Working Group – Community Noise Session – 5 VASTCON member abstracts submitted. Was hoping for more. Wish to determine if other non-VASTCON member abstracts were submitted and aggregate if so. Array Methods Panel Session planned The panel session, in which benchmark problems are provided for comparing and validating various microphone phased array processing techniques for source localization and quantification, will revisit the problems from 2015 and address several new problems.  The 2015 problems have been updated with additional data and objectives based on feedback from the 2015 panel session.  The 2016 problems have been identified and supplied to address physical source and measurement configurations which were not fully captured in the original problem set, as well as incorporate CFD/CAA into the analysis. 6 to 10 panelists anticipated

Other NASA Langley sponsored Blue Sky Workshop on “Quiet UAS/PAV VSTOL Approaches” held at National Institute of Aerospace, Hampton, VA, Aug 26-27, 2015. Intended to influence future NASA Aeronautics Research Mission Directorate projects through generation of new ideas which could lead to game-changing introduction of new UAS and PAVs into the air transportation system 60+ participants from across NASA, academia and industry 31 low-noise concepts were brainstormed by 8 breakout groups. Top two from each group were presented. Concepts generally fell into 3 groups Terminal area & operations Propulsor concepts Vehicle concepts Distillation of concepts in progress. A TBD publication is anticipated later this year.

Membership – Chuck Royalty

Membership Total membership of the TC is 35, which includes 27 Regular, 1 Associate, and 7 International Members. 50 Total Member limit, 35 Regular Member limit. It is intended to retain a core of productive senior members to assure continuity of the traditions and high standards that have become identified with the AIAA Aeroacoustics activities. We also hope to encourage multiple terms for members who are active contributors as sub-committee members and conference organizers. We see very little point in change just for the sake of change.

Membership: New Members Charles Tinney. University of Texas at Austin Junhui Liu, Naval Research Laboratory William Alexander, Virginia Tech Jason Anderson, Naval Surface Warfare Center Jeffrey Berton, NASA Glenn Research Center

From our Charter, 2001 SCOPE FUNCTION ACTIVITIES Development and application of Aeroacoustics technology for military and commercial aerospace systems. FUNCTION Promote the understanding and effective use of Aeroacoustics at policy and technical levels. ACTIVITIES Provide policy direction and key personnel for the Aeroacoustics Conference (AAC). Provide educational programs by sponsoring workshops, short courses, sessions, tutorials and conferences other than the major conference, the AAC. Facilitate review and publication of aeroacoustics books, proceedings, and journal articles. Advocate policy to AIAA on aeroacoustics topics of national interest. Promote understanding of standardization, technology, and other issues important to aeroacoustics. Coordinate with other AIAA Technical Committees and other technical groups (American Helicopter Society, ASME, etc.) with common interests. Hold joint conferences. Honor technical contributors through awards, nominations for associate fellows, and membership upgrades. Broaden the member participation base through creation and use of aeroacoustics subcommittees within the full committee. Promote investigations that improve state-of-the-art computational and experimental capabilities.

Web Pages… TAC web site ASG web site TC Topic: Web Pages Each TC needs a web master and a back-up/helper Great location to share information (e.g. minutes, charter, award process, photos) This is your face to the outside world for new AIAA & TC members Improvement to ASG TC web pages. Thanks! When was the last time your TC updated its webpage? Keep up the good work! TAC web site https://info.aiaa.org/SC/TAC/default.aspx Provides numerous documents (e.g. Chair manual, Self-Assessment) ASG web site https://info.aiaa.org/tac/ASG/default.aspx Has links to the various TCs and needs improvement

Other Topics Room size, not large enough to support attendees at SciTech: Eric Nesbit is aware of the problem and will work with organizers of SciTech 2017 Holding the summer meeting every other year in Europe was discussed. However the TC members from Government and Industry were very much against this idea because of travel restrictions. Lobbying Acoustics: Murray, Ahuja, Lyrintzis: It was suggested that ASG should be asked for funding to support this activity. We need a one page description of what the aeroacoustucs community is doing and how it is relevant to individual members of congress. The document should highlight what we are doing in each state. It was suggested that we should also discuss this initiative with other acousticsl and noise control societies. Action Item: Murray and Ahuja to start drafting a white paper Collection for Student Paper: no objections if ASG does not provide funds.
