duplicate the aerodynamics of the flight environment , even with small scale
models," said facility chief aerodynamicist Rich Wahls.nasa.

aircraft manufacturers to produce better performing airplanes with less risk. The stainless steel model, which looks like one-half of an
airplane cut down the middle from nose to tail, is mounted on the sidewall of
the wind tunnel. But making improvements is not easy, because of the complex
airflow issues encountered when flaps and slats are extended from a wing.
