Web page (N. Murray)
I can report that the website is being actively used to host the discussion board for the “Benchmarking Array Analysis Methods for Aeroacoustics" working group that is headed up by Chris Bahr.
 One request to pass up the chain.  The TC website is still built on Microsoft SharePoint Server  This is quite old, and there are a number of useful features that would integrate will with mobile/social media that are available on newer versions of SharePoint Server.  I would suggest that AIAA upgrade the SharePoint Server if possible to enhance the outreach opportunities for all the technical committees
Walt to discuss with Jim, upgrade.

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

12. Award Process 2015
Nominations: via AIAA with eligibility and nomination requirements
Aeroacoustics Award Subcommittee (AAS) for the 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.
2016 Award, given at AIAA/CEAS no Aviation participation in 2016

13. 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

14. Student Paper Award: Evaluation
Aeroacoustics 2015 Statistics
27 Entrants , actual will be likely closer 5-10
Student Papers Are Scheduled On First 3 Days Of The Conference – Naval Agarwal Confirms
Evaluation Of Papers: Based On Written Paper And Oral Presentation, students currently not aware of point system, should be; can we get TC members to evaluate live
Need Volunteers (or we can just assign to Committee members)
Written Paper Criteria (35 Points)

Aeroacoustics TC Meeting
Tuesday, 6 January 2015

16. Transformational Flight PC
The TFPC was established in 2013 to explore the potential of electric propulsion and autonomy technologies on enable new aviation missions and markets.
From the charter “Serves as a focal point for creation of new, on-demand aviation capabilities that will leverage enabling technologies such as electric propulsion, highly coupled aerodynamics, autonomous control, advanced vehicle configuration, and intelligent transportation systems.”
Organization:
Technical Challenges Working Group
Ultra-low community noise
Public-Private Partnerships Working Group
Prizes Working Group

17. 3 technical sessions @ SciTech 2014
TFPC Activities
3 technical SciTech 2014
6 technical sessions at Aviation Technology, Integration, and Operations Conference Aviation 2014
2 papers on flight vehicle acoustics
Transformational Vertical Flight Concepts Workshop held in partnership with AHS Advanced Vertical Flight and AIAA V/STOL TCs (August 2014)
~ 100 participants
TBD technical sessions at Aviation 2015

18. TFPC: Ultra-Low Community Noise
Technology Challenge
What are appropriate mission-dependent acoustic design criteria (and metrics to assess progress) and what technology developments are necessary to achieve them?
Flight vehicles under consideration are new, and fall outside the knowledge base. Source noise is expected to differ from current fleet. New class of missions expected to expose all segments of society to aircraft noise, not just those near airports.
Technology Gap 1: Acoustics Database – Vehicles and Standards
Technology Gap 2: Metrics – Community Impact at Short Range
Technology Gap 3: Prediction and Design Methods

19. HeroX prize – Sister organization to X-Prize
TFPC: Prize Opportunities Involving Noise
HeroX prize – Sister organization to X-Prize
$2M prize is in final stages of development for announcement in the spring
Prize won't have a high priority on noise but organizers are looking for simple way to enforce what 'quiet' means
Proposed rules to be issued in coming days for comments
Transporter prize
Much more of the focus on noise. Best chance to work on metrics.
Still waiting for another funder to come up with the other half of the $10M prize.

20. VASTCON Technical Working Group
The Virtual Acoustic Simulation Technology for Community Noise (VASTCON) Technical Working Group –
Established in 2012 to help advance the state of the art of virtual acoustic simulation applied to community noise problems, specifically those due to transportation and industrial noise.
Focus on aircraft flyover noise
Membership comprised of academic, industry and government organizations
Mission is to –
Share applied research supporting simulation applications, including sound synthesis and propagation, sound reproduction, and creation of virtual environments
Share the results of subjective testing utilizing these applications,
Seek new application areas

26. Membership (general)
Total membership of the TC for the year ending April 30, 2014 is 33, which includes 2 Associate, 6 International.
It continues to be the intent of the committee to limit membership to below the 50 member limit, consistent with the demographics of the field of aeroacoustics.
It is intended to retain a core of productive senior members to assure continuity of the traditions and high standards that have become idrntified 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.

27. Committee Membership (recommendations)
Tentative new members added to committee:
Eric Nesbitt, Boeing Commercial Airplanes
Doug Nark, NASA Langley Research Center
Charles Royalty, Honeywell
Amr Ali, Pratt and Whitney
Daniel Edgington-Mitchell, Monash University (International Member)
Rotating Off
Dmitri Popamoshou (per his request)

28. Reflections on Conference Model Transition
Conference Formats
We have been successful in getting SciTech 2015 back to a three day Aeroacoustics format.. The main issue going forward is to make this a permanent part of the SciTech template.
The organizing committee for the AIAA/CEAS Aeroacoustics Conference at Aviation 2015 is pressed for a three day format. This will probably not occur, however there is hope that a four day format can be negotiated. We hope to be successful and also make this a part of the Aviation Forum ftemplate.
The Aeroacoustics Award Banquet is now accepted as part of the Aviation Forum template. Including the banquet in the conference fee has not been accepted by AIAA, and is not likely to be for many reasons. Wont get fee included in conference fee, mailing list (Steve R)
Send out news letter or something in advance about Aeroacoustics for Aviation, possibly use web site (get the word out)
We tried to retain as much as possible of the format of the AIAA/CEAS Aeroacoustics Conferences of the past.
We were unable to retain our usual three plenary speakers, and now have the Aeroacoustics Lecture.
We retained the student paper award within the Aeroacoustics Conference.
We still have our own student paper award presentation, $500 prize split with CEAS, Walt asking for Industry support, TC to come up with the $250 (pass hat within TC) Tony to strong arm

29. Misc Notes:
Aeroacoustic Award: Helpful to have a list of nominations to identify candidates and not duplicate efforts. Should have a photograph of old and new award winners. (Comments from Krish Ahuja)
Publication: Photo for Review Article changed to F-35, other edits made without communications (automotive), Jeff Peters to get follow up from editor on why changes made, should have CEAS contributions
2015 Volunteer for Review Article, Dennis McLaughlin
2017 Tech Chair for SciTech, Tasos(?), Eric Nesbitt Volunteered at end of Meeting
Nathan may get pulled off on other commitments, may need another web-master
