Presently, when a physics motivated vehicle designer explores
designs for a new concept, he is often faced with an enormous
range of
choices and constraints. For an example, an aircraft designer
Aircraft shape, fuel type, and engine as his main free
variables. While
his main constraints are dictated by the laws of physics
(weight, size,
power, lift, and stall). Additionally, he has his objective
which is
typically some combination/subset of acceleration,
range, endurance, payload capacity (size, weight and power),
max and min
speeds, manufacturing cost, maintainability, reliability,
cost, takeoff length, landing length, noise footprint and other

I am interested in examining the following problem: Given a
set of
performance objectives, how does one determine the space of
available to the designer and find the optimal designs? How
does the
designer best visualize this space of options? Because he
doesn't want
just the answer, he wants to understand many aspects of the
While I'm interested in the general vehicle design problem, we
focus on aircraft design using a baseline tool that is to be
as a concrete example with which we can test our ideas.
