  1. 2145-392 Aerospace Engineering Laboratory II Dimensional Analysis and Model Testing: Lift and Drag, and Cl and Cd of An Airfoil Asi Bunyajitradulya (ABJ)

  3. Background • How can we estimate the performance (e.g., lift and drag) of a life-size prototype with the testing of a scaled model? • What underlying principle allows us to test a scaled-model and use the resulting data to estimate the performance of a life-size prototype?  Dimensional analysis and model testing

  4. Motivation for Dimensional Analysis and Model Testing In the design and development of engineering equipment, • we need certain data, • it is not economical to build and test a life-size equipment right from the beginning, • Computer-Aided-Design/Engineering (CAD/CAE) helps in the initial design stage, but it still requires verification from the testing.

  5. Lift and Drag, and Cl and Cd of An Airfoil,Dimensional Analysis and Model Testing

  6. Objectives • Test for the lift and drag characteristics of an airfoil at various angle of attack. • Determine Cl and Cd of the airfoil.
