  1. Aerodynamic tesing of rear mounted automotive spoilers(7/26/2010)

  2. Position of Spoiler Spoiler positions were measured from the top of the model to the top of the spoiler for the Y direction and from the beginning of the slant to the leading edge of the spoiler in the X direction.

  3. Attached spoiler & Thin Plate • There was no significant change in reduction when position 1 was attached • A thin plate at 5 or 10 deg worked just as well as a spoiler. • The plates used was about 0.02in. thick and 4in long • Continuing experiments with shorter thin plates

  4. Future Tests • Cd with Different slant angles • Flow visualization using white vinyl (on order) and fluorescent oil.

  5. CFD CAD Models

  6. Toyota car model • $4.50 per cubic inch for material • 8in x 8in x 12in sections • Design of sections and attachments

  7. Thank You
