Structures TC Liaison Report Bruce Willis

2

• Procedures Subcommittee - Finished a TC guidebook to document TC processes and procedures (generic calendar of activities, SDM representative duties, SDM Chairs duties, Fall meeting host duties, etc.), and describe TC structure (officers, subcommittees, etc.). This might be a good template for us to do a similar project, expanding our existing Member Guidelines.

• Their Education Subcommittee is working on a design competition. They are also interested in teaming with us (SDTC) in our education outreach.

• Jeanette Domber, of Ball Aerospace, is the new STC Chair. Steve Russell was elected Vice-Chair. Lisa Hardaway, Ball Aerospace, was re-elected as Secretary. Dawn Phillips, NASA MSFC, is the 2013 SDM representative. Johanne Heald, Canadian Space Agency, will be the SDM representative for 2014.

Both the Applied Aerodynamics and the Fluid Dynamics TCs have sponsored sessions on Fluid/Structure Interactions and Aeroelasticity at the Aerospace Sciences Meeting. It will be important with our organizers for SDM to be aware of the sessions these TCs are organizing and when these sessions are scheduled to avoid conflicts if possible.

Boeing Research & TechnologyOn behalf of the AePW Organizing Committee

Information assembled by Jennifer Heeg(jennifer.heeg@nasa.gov)

October, 11, 2012

AePW Website contains all presentations from the workshop:https://c3.nasa.gov/dashlink/projects/47/

Thank you for your support of the 1st AePW- politically, organizationally and from a technical participation standpoint.

AIAA Aeroelastic Prediction

Workshop heldsuccessfully* at last year’s SDM

conference

*without violence, pestilence or nervous breakdown

AePW Status• Workshop presentations & workshop summary

document are available on the AePW website(https://c3.nasa.gov/dashlink/static/media/other/AEPW.htm)

• Special sessions planned at ASM2013, SDM2013 & IFASD2013

• Discussion sessions for path forward planned during last time slot of each special session- we welcome feedback (technical, planning, administrative) to improve the activity

• May want additional special session at SDM 2014• Coordinating publications for journal articles; targeting

2014 publication

Forum 68 Abstract Deadline Policy

• Continued the deadline policy implemented by Judah Milgram and Susan Gorton for Forum 67

• No extension of the abstract deadline: Friday October 7.• The submission website will be kept open for some period of

time after the deadline• … but there is no guarantee that late abstracts will be reviewed• Authors are encouraged to get abstracts in on time, the later it

is submitted the less chance that it has of being reviewed.• Up to the individual technical committees as to how they will

treat late submissions (more competitive sessions will probably not consider late abstracts)

Distribution of Final Papers in The Program

Academia Only: 51

Industry Only: 56

Govt Only: 22Govt & Industry: 42

Govt & Academia: 25

Industry & Academia: 23

Two papers by unaffiliated individuals (both in History)

43 papers had at least one international author

Industry, Govt & Academia: 9

Academia Participation in 99 Papers (43%)

Government Participation in 89 Papers (39%)

Industry Participation in 121 Papers (53%)

17

• Nice distribution of Industry, Government, and Academia– 43% had representation from some combination of

industry, government, academia• No shortage of papers from industry

– Over half of the papers have at least one author from a business (either large or small)

• Good international participation– Authors representing Germany, France, UK, Italy,

Canada, Korea, China, Brazil (probably more)

Approval Cycle Issues Anecdote #1

• Authors submitted papers to government agency 4 weeks prior to the deadline

• Could not get timely approval because the associated government program “was in limbo for awhile”.

• Government agency never completed review• At least four high quality papers will not be

published due to failure of government agency to review papers

19

Approval Cycle IssuesAnecdote #2

• Several papers held up in export control office of a major company (“Company A”)

• Papers submitted for approvals 6 weeks prior to deadline• Approved by government sponsors• Passed corporate review at companies “B” and “C” who also participated in the

research• On day of deadline export control officer at company A” told authors to submit

the paper along with an Export Warning!• Authors realized this was not a good idea, but could not convince export control

officer to budge• Two papers removed all content (and authors) associated with company “A”,

final papers included only material from companies “B” and “C” and academic partners

• At least one other paper was not published due to this issue
