A duct in which the effects of airflow past objects can be determined. The steady-state forces on a body held still in moving air are the same as those when the body moves through still air, given the same body shape, speed, and air properties. Scaling laws permit the use of models rather than full-scale aircraft. Models are less costly and may be modified more easily than full-scale, production-level vehicles or aircraft, and in the cases of flight, conditions may be simulated that would be impossible or dangerous (Fig. 1).
