Jeff Hamstra, the P&E Director of the AIAA TAC, visited the LPTC, and presented a synopsis of the P&E meeting. He stated that the new AIAA constitution and the new AIAA organization were of tangible benefits.

Don Sargent presented an abbreviated version of the minutes, and the list of Action Items, Attachment 3, from the LPTC Winter held on January 20, 2016. New Action Items from the Steering Subcommittee meeting held on July 19, 2016 were also reviewed. The discussion and resolution of these Action Items are found in the respective subcommittee reports in following sections of these minutes. As results of these discussions, the Action Items were updated, are listed in Attachment 6.

Conference Planning – David Ransom

2016 JPC, Salt Lake City, UT, 25-27 July 2016Two LPTC members held leadership positions for the 2016 Propulsion & Energy Forum: Justin Locke is the Technical Chair for the 2016 P&E Forum, and David Ransom is the Deputy Technical Chair for Space. The LPTC members applauded their accomplishments.

Bill Marshall, the Liquid Propulsion Technical Area Organizer for the 2016 JPC, presented the results of the Liquid Propulsion sessions.

A “Lessons Learned” session was held as one of five separate Forum 360 sessions, instead of as a liquid propulsion history session. The lessons learned call for LP papers attracted only two abstracts, and both were subsequently withdrawn.

Reusability was originally considered for a LP history session, but was preempted and deferred by a Forum 360 invited panel session on Launch Vehicle Reusability for this year’s JPC.

Reusability is recommended to be a LP history session at the 2017 JPC. First half of the session could be the shuttle/history perspective, lessons learned during Shuttle; and the second half would be the modern perspective, challenges, innovations, etc.

It is strongly encouraged that future history panel sessions be coordinated with TAO earlier in the process to avoid conflicts.

87 liquid propulsion abstracts were finally accepted and scheduled for the 16 LP sessions that were held.

17 LP papers were withdrawn, leaving 70 papers submitted and presented at LP sessions.

The number of LP abstracts and the number of LP papers were the lowest since 2012. Authors generally were very good about 1000-1500 word abstract length.

Bill Marshall thanked all the LPTC members for supporting the TAO efforts, and thanked Justin Locke, Dave Ransom, Ann Ames, and rest of AIAA conference team for their responsiveness and patience.

2017 JPC, Atlanta, GA, 10-12 July 2017David Ransom is the Technical Chair for the 2017 P&E ForumVineet Ahuja is the Liquid Propulsion Technical Area Organizer for the 2017 JPC.

Vineet reported the LP topics in the call for papers, which reflected the topics of abstracts submitted for 2016 JPC

Vineet will request an update of LPTC members’ areas of expertise, for reviewing abstracts and for chairing technical sessions

Deadlines and logistics for 2017 JPC will become available soon

Subcommittee Reports

Treasurer’s Report – Stewart Bushman The LPTC balance is $ 1,414.38 as of January 2016 and also as of July 2016 There was no LP 2015 Short Course, so there is no Honorarium income for 2015. The projected 2016 expenses are

o $ 0 for the Young Professional and Outstanding Student awards (Awards subcommittee voted to defer these awards for 2016, based upon low Treasury balance).

o $ 500 for the July 2016 LPTC General Meeting. The anticipated 2016 revenue from the LP Short Course at JPC in Salt Lake City is $3,000 The projected December 2016 LPTC balance is approximately $ 3,900. LPTC account for the suitcase rocket project:

o January 2016 balance = $ 2,311o Disbursements, January thru July 2016 = $ 0o The balance in this account as of July 2016 is $ 2,311

Awards Subcommittee Report– Stewart Bushman• The 2015 LPTC Best Paper was selected by the subcommittee: AIAA 2015-3769:

O. Kartuzova and M. Kassemi, “CFD Modeling of the Multipurpose Hydrogen Test Bed (MHTB) Self-Pressurization and Spray Bar Mixing Experiments in Normal Gravity: Effect of the Accommodation Coefficient on the Tank Pressure.”

• Dr. Gary Flandro, the LPTC nominee, was the 2016 Wyld Award winner.• The 2016 Young Professional and Outstanding Student awards were not awarded due

to lack of funds. A reduced award value option was voted down by the Awards Subcommittee membership. This closes Action Item 16 Winter-1.

• Since the 2016 short course is taking place and generating revenue, the Awards Subcommittee expects to solicit nominations and to provide $1,000 awards in both categories in 2017.

Education Subcommittee Report – Timothee Pourpoint The 2016 AIAA Short Course, “Fundamentals of Liquid Chemical Propellants and

Applications for Less-Toxic Alternatives” was conducted on July 23 and 24, 2016, in Salt Lake City.

o The course was conducted before the JPC (dates were determined by AIAA).

5



o There were 6 student participants. The three LPTC instructors were Jörg Riccius, David Lineberry, and Timothee Pourpoint.

Promotion and registration for the Short Course did not go well, and registering for the course was difficult

The already-recorded history sessions were reviewed by BJ Austin and evaluated as possible webinar courses, to be offered by LPTC. However, there still has been no progress. A lead person is needed to implement this potential source of income.

Two Suitcase Rockets have been built. Thanks to SWRI, ULA, AR, Jacobs, OSC, Orbitec, SpaceX, ERC, and Moog for their support.

o Letters of thanks to the Suitcase Rocket donors have not yet been sent. There is some uncertainty about the addressee for each donor company. Action Item 16 Winter-2 remains open.

o David Ransom prepared excellent support documents for the Suitcase Rocket.o We need another $3K to build a third suitcase (for Europe) and cover shipping.o Jeff Schnackel is stepping down, so a new lead is needed for this effort.

The “STEM Materials” folder on the LPTC webpage under “Shared Documents” is populated with class visit support materials suitable for a range of ages from elementary through high school. The materials were developed by NASA and the folder will continue to be populated as additional materials found.

History Subcommittee Report – BJ Austin The History Subcommittee voted to confirm BJ Austin as its Subcommittee Chairman.

This closes Action Item 16 Winter-3. The History Session at this year’s JPC was entitled “Lessons Learned”. The session was

recorded by AIAA.o Stewart Bushman (Awards Subcommittee) provided certificates of appreciation to

the speakers. This closes Action Item 16 JPC-3.o BJ Austin gave the last of the coffee mugs to the speakers. BJ will seek donors for

more mugs. He estimates the cost would be $300 to $400 for 72 mugs. Action Item 16 JPC-4 remains open.

The Library of Congress was contacted to solicit interest in the LPTC recorded history sessions, with some positive response. The next steps would be for the LPTC to generate synopses of the sessions, and to bring samples of the videos to the Library. Action Item 15 JPC-1 remains open.

Publications Subcommittee Report – David Ransom and Vineet Ahuja Year in Review inputs were submitted to AIAA, and were published in the December

2015 issue of Aerospace America.o Thanks to all for very interesting contributions.o A few errors escaped editing, and we plan to request better feedback from

AIAA before going to print. Vineet Ahuja will again lead LPTC submissions of Year in Review inputs to AIAA.

o The AIAA deadline for 2016 inputs is Friday, September 16th. Contributions in the form of 4 to 5 line summary about major advancements or accomplishments are therefore needed by August 26th.

o AIAA wants all pictures/images in JPEG format.

LPTC members are requested to be on the lookout for conference papers that are suitable for journal publication. In response to the talk by Joseph Powers, the Editor in Chief of the Journal of Propulsion and Power, LPTC members are urged to submit good papers to this Journal.

Membership Subcommittee Report – Scott Forde The membership congratulated Kent Pugmire on his advancement to AIAA Fellow, and

Tom Giel on his advancement to AIAA Associate Fellow. Two other members were nominated to advance to Associate Fellow status.

o Members were encouraged to upgrade their AIAA membership category to Senior Member, Associate Fellow, and Fellow. The LPTC would help with recommendation letters.

Soon after the January 20, 2016 LPTC meeting, Scott requested and received permission from Jeff Hamstra, the P&E Director, to waive the 50-member LPTC limit and allow 52. Consequently, two new LPTC members were added to bring the total membership to 52: Francois Lassoudiere and Samantha Alberts. This closes Action Item 16 Winter-6.

As of July 27, 2016, we have a full complement of 52 current members with the distributions shown in Attachment 4, by employment category and by AIAA membership category. There are 33 regular members, 9 international members, and 10 U.S. members under 35 years old.

In the past year, four members who have made notable contributions to the LPTC have retired, primarily because they have repeated difficulty attending JPC meetings: Alfredo Lopez, Patrick Alliot, Gary Grayson, and Alan Frankel. Scott has suggested to them that they become Emeritus Members. This closes Action Item 16 Winter-4.

Current subcommittee assignments are shown in Attachment 5. New members without subcommittee assignments were asked their preferences, with the following results:

Kenneth Phillipot History SubcommitteeChristopher Radke Publications SubcommitteeBrandie Rhodes Education SubcommitteeSamantha Alberts Deferred (not present at meeting)

This closes Action Item 16 JPC-5. Scott sent around a roster for the members to review and update contact information as

appropriate. In addition, resumes are missing for some new and existing members, and should be submitted to Scott.

Scott Forde asked that members who have been on the committee for more than two years should evaluate his or her level or involvement on LPTC:

o Did you participate in the last two JPCs?o Did you participate in the January virtual meeting?o Am I active in a subcommittee's activities?o Will your organization support your participation in the TC’s activities?o Will I be able to participate in the next JPC? And in the next January meeting?

The two-year terms of Ivett Leyva as LPTC Chairman and of Mike Meyer as LPTC Vice Chairman both expire in May 2017. Mike will advance to be LPTC Chairman at that time. Ivett nominated David Ransom to be the new LPTC Vice Chairman, and David was elected to this position. This closes Action Item 15 JPC-5.

Don Sargent is retiring as LPTC Secretary. Don will prepare the minutes of this 2016 Summer LPTC meeting. Matt Deans was nominated and elected to be the new LPTC Secretary.

Stewart Bushman is vacating his position as LPTC Treasurer, since he is now the Awards Subcommittee Chairman. Bill Marshall was nominated and elected to be the new LPTC Treasurer.

Christoph Kirchberger volunteered to be the Liquid Propulsion Technical Area Organizer for the 2018 JPC, to be held in Cincinnati. The LPTC confirmed his appointment.

Scott Forde distributed LPTC shirts to members who did not have these shirts.o The remaining supply of shirts has now been exhausted, and Scott Forde will order

additional shirts. Tee shirts will be purchased instead of the more expensive knit polo shirts. Action Item 16 JPC-1 remains open.

o Ivett Leyva will ask Jeff Hamstra for the procedure to request funds for purchasing LPTC shirts. Action Item 16 JPC-2 remains open.

Webmaster’ Report – Justin Locke The membership roster page has been updated. Members are encouraged to verify/edit their bios. For newer members, if your bio is

not in the “Membership” folder, please send your info to Justin. AIAA is looking to replace SharePoint, which is not adequate for AIAA TC and

committee needs

Liaison Reports Electric Propulsion Liaison Report – Mike Meyer

o The Electric Propulsion Technical Committee is developing several standards documents that are focused on diagnostics/measurement techniques such that consistent results will be obtained by different groups.

o The Electric Propulsion Technical Committee revitalized their short course and is considering a second version to conduct jointly with the Plasmadynamics and Lasers Technical Committee.

JANNAF Liaison Report – Mike Meyero The JANNAF Liquid Propulsion Subcommittee will conduct a Technical

Interchange Meeting in August in Huntsville, AL, to address additive manufacturing for propulsion applications.
