Hi EWB,

Just to jump in from an outside perspective..

AERO faced similar issues last Spring when we started tackling
design and continue to as we refine our design.


The race car's design/build cycle goes something like this:

  1.  Plan: Research rules of the race and establish action
      objectives that maximize performance within rules and
      available resources.

  2.  Do: Do the plan (analyze, model, source, fab, etc.).

  3.  Check: Compare results with objectives. Report back to Team.

  4.  Act: Based on results refactor process to improve before next
      cycle begins.

The most important resource has been good information. Our
collaboration mechanisms (a Wiki, version controlled repository,
email lists) have proved central to our ability to make good
decisions and thereby produce good results. Testing out our ideas
would be worthless unless we incorporated results into an evolving
(learned), always improving design.

Participation is crucial. Our meetings follow an agenda and always
include time at the end for every person to speak and report
accomplishments from the last week and plans for the week
coming. Meeting agenda is always posted to our Wiki allowing for
any team member to add to it (very useful). The agenda maintains
focus that yields shorter meetings and it has been our experience
that the shorter meetings are usually our most productive.

I had the opportunity to see Brett present your project this week
to my Engineering Management class. He gave a really good
introduction to the background of the effort, and then did a good
dimensional analysis for the design. This seems like a perfect
place to begin. The evaporator is a very interesting engineering
problem, and one in which you could make a big, positive impact
for all stakeholders involved.

Be sure to bug us over at AERO if we can help or you have any
specific questions for how we are organizing our problems or
executing their solutions.

Best of luck!

Cheers, Andrew
