Chairman Winters called the Steering Group meeting to order at 3:05 pm.
I.
Brian reviewed his report to the Propulsion & Energy Group meeting (1/13/02) on the status,
organization, and effectiveness of the LPTC:
A. We’re reaffirming our purpose, revising our 3-year plan, aggressively pursuing involvement
in liaisons, awards, and participation, and firming up our organization.
B. We have 40 members, 32 of which count toward our limit of 35 (the limit does not include
international or young members).
C. LPTC’s charter is being revised to more accurately reflect our operations.
D. TAC governance: our succession planning and officers’ training are in accord with TAC
guidelines.
E. Liaisons: we need to address a weakness in liaisons with local/regional AIAA chapters (but
we agreed that we have sufficient involvement with LA section to check off that metric).
Membership participation: while we assign each member to a subcommittee, track
attendance at meetings, and send notices to inactive members, 80% of our activity is performed
by 20% of our members. We are developing “motivational methods” to encourage participation.
Discussion: Steve Fisher suggested we need some unique activity / value creation to draw
people. Kent Pugmire said there is value in the representation of the organizations too. Brian
would like to show who did the work in the subcommittee reports, and to ensure there is valuable
work to be done. Kent suggests a LPTC display board be developed to create visibility into the
propulsion community’s current activities, and that we display it (in the registration area, or
wherever we are permitted) at the JPC and Reno. It was agreed that this project is an appropriate
function for External Affairs. Kent agreed to change subcommittees to help Steve with this. We
will check into what display stands are available as well as obtaining funding to buy one.
F.
G. Education – our Short Course crisis was discussed, and the need to resolve it ASAP. We’ve
had a long tradition of holding this, and it’s an income source ($1000 if we can get 10 attendees),
but our Education subcommittee chair position is vacant with Ken Smith’s resignation. Brian is
working with AIAA to hold a spot open for a course. We discussed metrics in this area and
agreed that, based on local activities, we can check off our support of higher education programs,
K-12 programs, and community programs.
H. Publications – We discussed weaknesses in our metrics for this area. We identified no book
development support, but we can take full credit for design guides, newsletters/bulletins, Journal
articles, papers, and the Year In Review article.
Awards/Scholarships – We could identify no support for Student awards or Young Engineer
awards. We’d like to work to re-establish a continuing Student award. Under Lifetime
Achievement awards, we have not had nominations recently for the Wyld or P&C awards.
Action: we made it our goal to have a call for nominations for the Wyld award at our LPTC
meeting in July. We did take credit for the Service award and Congressional Visit Day
involvement.
I.
II.
LPTC Charter
A. Brian passed out a revised charter which he updated and suggested changes (e.g., Vice Chair
would be responsible for the Steering Committee meeting).
B. Action: We (the TC) need to review and get comments back to Kurt Kreiner for format and
content. Brian will email the charter to the TC, and Kurt will incorporate by March.
III.
3-Year Plan
Metrics are to be used as a guide, not because we like them but because they specify everything
the TC is expected to do. Proposed: assign each “metric” to a Subcommittee. These
subcommittees/officers don’t DO the activity, they may delegate, but they are responsible for
reporting the status of the metric. The agreed-upon assignments are as follows:

IV.
Short Course Crisis – already covered above
V.
Membership Involvement Ideas
A. Steve: Alternate locations for the January meeting would help LPTC attendance.
B. Dave: Perhaps we should set aside a short time after each TC meeting for subcommittee
meetings.
C. Brian: Would like to encourage each subcommittee chair to hold a separate meeting of their
subcommittee.
VI.
Organization
A. Subcommittee chair vacancy: Bill Anderson was suggested for Education and to organize the
Short Course. Brian will ask him.
B. Standards: Should we re-establish the Standards subcommittee, since AIAA is stepping up to
this? It was discussed whether this falls under Technology Assessment, or should be ad-hoc/asneeded since it’s a big time commitment. We’d like to be proactive, so we will discuss at
tonight’s general membership meeting, with Craig Day of AIAA, what should be the TC’s role on
standards.
C. Should the Aerospace America article be reassigned to Technical Assessment so they have a
metric? Should TC liaisons be moved to External Affairs? Brian will leave liasons reporting
directly to the Chair. Action: The Charter, with its proposed changes and metrics assignments,
will be sent to the members for review along with the minutes, comments due back to Kurt.
Adjourned at 5:45pm.

Chairman Winters called the meeting to order at 6:10 pm. Dinner followed the introductions and
welcome.
I. AIAA Business
A. AIAA Strategic Plan (Steve Schultz)
Steve discussed four new areas that AIAA has decided it should get into (which could lead to new
TCs, partnerships, publications, and meetings):

Aerospace information and communication

Air traffic management

Logistics

Systems engineering
New TCs and “champions”:

Systems Engineering Group

Aircraft & Air Transportation Systems & Ops
New publications:

Online Letters, to be prepared quarterly starting Jan-04. This needs Associate Editors –
the intent is a forum with less of a review process than the Journals.
B. AIAA Business Development (Steve Schultz, Emily Springer)
Steve said Business Development is the AIAA group where ideas for activities would be funneled
– an interface between members and staff.
Emily passed out AIAA TC shirts to the TC members who hadn’t gotten them previously.
C. AIAA Standards Development (Jim French)
The purpose of this activity is to attain “consensus” documents through a cooperative process
accredited by American National Standards Inst. (ANSI). The responsibility/ownership of a
document will rest with the particular Committee on Standards, often linked with the TCs and/or
with the International Standards Org. (ISO). The process provides for:

Special Reports (no formal consensus needed)

Guides (advisory)

Recommended Practices

Standards (“nearly mandatory”), e.g., MIL-STD-1522 which like some other abandoned
standards will become AIAA-XXXX (others will go on to the ISO). Another example is
the WSTF hypergol standard which is becoming AIAA SP-084-199, SP-085-1999, and
SP-086-2001.
Liability exposure: their judgement is that AIAA is “probably” not at risk. ITAR restrictions: so
far, these standards are not limited by ITAR.
D. Congressional Visit Day (Paul Looney)
This annual AIAA event is scheduled for March 20-21. The entry fee ($200 by Feb. 28) covers
the costs of meals and events. To register contact Brian, or Paul at AIAA Government Relations
(703-264-7625).
II. JPC 2002 Status (Carl Guernsey)
Carl presented the list of sessions for the 2002 Joint Propulsion Conference in Indianapolis
(Attachment B). There are presently 108 papers in 16 sessions. Comments are due from the
session chairs by January 24, including the order of the session, so that the program can be
finalized Jan. 31. Carl will try to get the abstracts sent out in some form next week.
There was discussion about how the session chairs can review the abstracts. What is the chair’s
reviewing role if the acceptance letters have already gone out (at the AIAA level) before we have
access to the abstracts? Dave McGrath (AIAA) answered that we still have the right to reject an
abstract, even if an acceptance letter has gone out – the conference organizers have merely done
the first-level screening. The system is still being improved.
Carl feels the Call For Papers needs to be reorganized to track better to the sessions. He
recommends having specific sessions included in the Call and the Abstract-submittal site. We
might want to revise the response we’ve already submitted for the next Call based on this
comment.
III. Propulsion & Energy Business (Dave McGrath, P&E Group Director)
Future Joint Propulsion Conference locations:

2002 – Indianapolis

2003 – Huntsville

2004 – Orlando or Fort Lauderdale pending a site survey (Pratt & Whitney sponsoring)

2005 – TBD, West Coast location
There is a lack of companies coming forward to sponsor these, so a plan is in the works to spread
the cost burden among a consortium.
Dave will take our concerns about Abstracts to the TAC. Call him with any questions.
IV. Old Business
A. Moved/seconded/passed to approve the 2001 Salt Lake City LPTC meeting minutes as
previously distributed.
B. P&E and LPTC logos – we still need ideas – please submit to Brian.
C. David Perry still needs to get biographies from most of us. Send him a single page,
preferably with a photo.
D. Standards Committee roster – this item is still open.
E. Standards Document item (review of the European standard) – closed, comments were
received.
F. AIAA funding requisitions – item still open, no requisitions have been made.
G. LPTC Short Course – this is a crisis due to Ken Smith’s resignation to go to another
committee. We’d like to keep the tradition going, but we need an organizer, instructor(s), and
topics. Per Patricia (Trisha) Carr of AIAA: LPTC’s course has always been one of the more
popular ones. The need is urgent to identify the course so it can be promoted. Benefits:
fundraiser for TC, showcase emerging issues, showcase TC, build recognition and credibility.
The preferred timeline for implementing a professional development course calls for a proposal to
be submitted 9-12 months out. This year, due to the holiday, the course dates are immediately
following the JPC.
H. Alternate site for January LPTC meeting – our good plans for this year were overtaken by the
9/11 events and ensuing security issues. Ideas are sought for next year – it’s safer to plan on a
non-governmental location. Brian will solicit ideas in the next newsletter. There was some
discussion about whether it’s advantageous to meet in conjunction with a conference – for some
people this makes it harder to get travel budget, for others easier, and some people need to be at
Reno anyway.
I. LPTC Charter recommendations and updates – The draft charter was prepared, will be
merged with the reporting metrics, and then sent out for review, to be ready for us to formally
adopt at the JPC meeting. This fulfills the “handbook” item under old business.
J. A rousing “good job Steve” on the Highlights article.
V. Subcommittee Reports
A. Awards (Winters, for Keith Coste)
1. Wyld award – we are short on good nominations (none received from members but
Keith submitted a package). Brian suggests we decide on a nominee as a TC at our next
meeting – action: we should all bring candidates’ names to the JPC.
2. Need nominations for 2001 JPC Best Liquid Propulsion Paper. Action: Each
session chair needs to send their session’s nomination to Keith.Coste@aero.org. He
cannot access AIAA’s session reports forms (not a new problem).
3. Undergraduate scholarship, LP – the LPTC is to participate in the selection, but how
actively? Currently AIAA distributes “named” awards to top seniors without
differentiation between their career interests. Two options are being discussed, as to the
level of TC involvement in choosing candidates. Discussion consensus was that we
should be closely involved to ensure it goes to a person with appropriate (LP-related)
interests. Brian will pass on Max Roler’s suggestion that the award be based on the best
student paper on a liquid propulsion topic at the JPC.
B. Education (Winters - acting)
1. Brian opened the floor for nominations to chair this subcommittee. Bill Anderson,
not present, was nominated in absentia and was approved by voice vote, subject to his
agreement to serve.
C. External Affairs (Fisher)
1. The Highlights article came together well – thanks for the submissions. We were
allocated 2 pages and 2 photos.
D. Technology Assessment (Fisher, for Jim Lobitz)
1. An invited session for Reno was not pursued this year due to our earlier plans.
2. Jim is dropping off the TC, so the floor was opened for nominations to replace him as
subcommittee chair. Max Roler was nominated and approved.
E. History (Darrow)
1. Last year it was hard to get papers/speakers for the Lessons-Learned session and we
had to merge ours with the ASME’s session. This year there aren’t enough for a session.
2. We need suggestions for Historic Site designation, such as Santa Susanna, AF Rocket
Lab. Forward them to Rich Darrow.
F. Membership (Perry)
1. The main activity is updating the membership list. He reminds us that he needs bios,
preferably with a picture, even a real old one. This is not a resume or curriculum vitae,
just a narrative sketch of what’s most important about your work, including academic
background. Two examples – Steve Fisher’s and Clarke Hawk’s – were passed out as
models. Action – bios are due by the end of February.
G. Publications (Calvignac)
1. No report, Jackie was not present.
H. Liasons
1. None present to report.
VI. Treasurers Report (Thornburg)
A. July 2000 balance was $100.66, plus a $6117 deposit and a $5000 withdrawal for the
scholarship, left a balance of $1217.66 as of May 2001. The Jan. 2002 balance is still $1217.66.
B. We appear to be missing a deposit from the 2001 short course. Jeff will track down the
missing $2000 deposit. Steve Fisher remembers that we are paid up for the perpetual scholarship
fund (Scholastic Foundation).
C. The procedure to request AIAA funds, as a reminder: TC Chair requests check to Staff
Liaison, the check is sent to the Chair, and the check cannot be made out to the Chair. Brian gave
examples of funding requests: speaker’s expenses, education programs, display board.
VII.
Web Site (Brian, for Gaspare Maggio)
A. Need feedback on our TC homepage (WWW.AIAA.ORG/TC/LP) to Gaspare.
VIII.
New Business
A. LPTC Organization
1. Brian presented a new org chart, which is to be updated as a result of today’s
meetings. Standards is to be kept in an inactive mode, with its duties to be fulfilled by
Tech. Assessment Subcommittee.
2. Seven new applications were received for LPTC membership.
Moved/seconded/passed to accept these 7 members, to begin work at Indianapolis.
B. 2001 JPC (Final Report), Salt Lake City (Pugmire)
1. Kent said good job, thanks to the TC on this meeting. Good sessions, good
organization of papers (i.e. putting the riskiest ones at the end), good adjustments to onthe-spot problems, <15% no-show rate. Max Roler suggests that session chairs be
prepared for no-shows, in particular maybe asking presenters scheduled for the last day of
the conference to fill in any gaps by presenting their papers.
2. We need to coordinate LP sessions with ASME, and target our sessions well in
advance. There is also a need to coordinate with the ad hoc session organizers.
3. The session schedule and room size allotments got re-ordered late (February),
resulting in conflicting sessions. The schedule had to be restored by May to resolve it,
but it still left conflicts. Advice to organizers: Don’t number your sessions nonsequentially, as that caused the problem.
C. 2002 JPC, Indianapolis (Wang)
1. This was covered earlier. Reminder – draft session lists are to be sent out soon; there
is still time for additional abstracts. We are especially short in the RBCC session.
D. 2003 JPC, Huntsville (Winters, for T. Smith)
1. The Call for Papers is to be refined some more, as discussed previously. The theme
is “Powered Flight – The Next Century”.
E. LPTC Annual Report (Winters)
1. Brian reported our metrics status, and the Steering Group’s additions of items for
which we can take credit. Discussion led to our checking off of #C3 due to our liaison
with other organizations such as ASME.
2. The remaining un-checked metrics are E5, E11, and E12.
F. Other New Business
1. Carl Englebrecht requests the ’03 Call for Papers include Non-Toxic Propulsion
Systems (as opposed to Propellants or Thrusters). He will supply a paragraph.
2. ITAR: the question was raised as to whether ITAR restrictions cause papers to move
into the JANNAF conference, and do we have an interface with JANNAF? Discussion:
Steve suggests we not pre-judge ITAR compliance but leave that to the companies
submitting papers. Kent reports that AIAA isn’t having classified or NOFORN sessions
in conjunction with JANNAF, as we had in the past.
3. Visitor Eric Rice reported on a new Space Colonization TC (subject to TAC vote).
The scope includes colonization, terraforming Mars, in situ resources utilization,
exploration, and space tourism. The goal is to excite the public about space and guide
decisions.
4. Bill Wang suggests we have a standardized Call for Papers. It was agreed that Tim
Smith would generate this, with input from Bill and Kent.
5. The Microgravity TC asked for a liaison with us to provide coordination on
propellant management issues. Bill Knuth was nominated and elected in absentia to be
our liaison with Microgravity.
6. A liaison with the Space Colonization TC was deferred to the JPC meeting because
this TC has not been formally constituted yet.
IX. Adjourned at 9:30 pm.
