Teaching the Principles of Flight with Wind Tunnel Models

摘要

In the TL121 lab room there are four "AirflowBenches" for laboratory exercises. They are used toperform various aerodynamic experiments. In thesecond laboratory exercise, you will:1.Measure and plot the drag polar (CD-α curve) of aNACA0015 airfoil; compare with results from theliterature.2.Compare the theoretical (inviscid) and themeasured pressure distribution on a circularcylinder.
