The document summarizes the design of a low speed subsonic wind tunnel. It introduces the problem of students facing difficulties observing airfoil maneuvers and flow properties. It then outlines the objectives to build a scaled wind tunnel to check aerodynamic parameters. It discusses assumptions made about fluid flow, limitations based on the structure, additional features like displays and units. It also reviews literature on controllers and sensors and establishes minimum standards for measurements and output.
