MAE 253: Experimental Aerodynamics I

MAE 253 is the introductory course to experimental aerodynamics, taught to sophomores in the low-speed wind tunnel. Topics covered instrumentation, data acquisition techniques, data processing, and technical report preparation. Experiments involve pressure and force/moment measurements of various aerospace vehicle components with supplemental flow visualization. Students learn to use instruments like a pitot tube, turbulence sphere, airfoils with pressure ports, six-axis load cells, and a wake rake.

Syllabus

Experiments
  • Pressure Transducer Calibration: Obtaining the calibration curve for an Ashcroft® differential pressure sensor using a water manometer and a pitot tube.
    ( Handout | Powerpoint )
  • Wind Tunnel Turbulence Characteristics: The turbulence characteristics of the wind tunnel are found using a turbulence sphere.
    ( Handout | Powerpoint )
  • Airfoil Aerodynamics: Finding the lift acting on an airfoil at different angles of attack using static pressure ports on the airfoil surface. Finding drag experienced by an airfoil using a wake rake to survey the dynamic pressure deficit behind the airfoil. Using the xfoil code to obtain low-order computational predictions for experimental results
