Dr. George E.P. Box wrote a great paper on Teaching Engineers Experimental Design With a Paper Helicopter that can be used to learn principles of experimental design, including – conditions for validity of experimentation, randomization, blocking, the use of factorial and fractional factorial designs and the management of experimentation.

I ran across an interesting blog post on a class learning these principles today – Brad’s Hella-Copter:

For our statistics class, we have been working hard on a Design of Experiments project that optimizes a paper helicopter with respect to hang time an accuracy of a decent down a stairwell.

We were to design a helicopter that would drop 3 stories down within the 2ft gap between flights of stairs.

[design of experiments is] very powerful when you have lots of variables (ie. paper type, helicopter blade length, blade width, body height, body width, paperclip weights, etc) and not a lot of time to vary each one individually. If we were to individually change each variable one at a time, we would have made over 256 different helicopters. Instead we built 16, tested them, and got a feel for which variables were most important. We then focused on these important variables for design improvement through further testing and optimization.
