Universities strive to develop their students’ abilities to solve problems as well as actually make things. One laboratory teaching method we use is a contest in which students make water rockets, use quality engineering to find their optimal parameters, and compete to see whose rocket can fly the farthest. Factor analysis is a standard method of solving problems, but the students frequently fail to find factors because they lack sufficient technical knowledge. We therefore teach our students the Taguchi approach so that they can learn to set design parameters in a way that is easy for them to understand. When the air resistance of the rocket is taken into consideration, we discovered that the ideal functional relation between flight distance and compressed air pressure is a direct proportional relation. When the compressed air pressure is within the parameter setting range, we found that flight distance robustly follows the predicted value.
