Wind Noise and Drag Optimization Test Method for Sail-Mounted Exterior Mirrors 2003-01-1702

An L18 Taguchi-style Design of Experiments (DOE) with eight factors was used to optimize exterior mirrors for wind noise and drag. Eighteen mirror properties were constructed and tested on a full size greenhouse buck at the Lockheed low-speed wind tunnel in Marietta, GA. Buck interior sound data and drag measurements were taken at 80 MPH wind speed (0° yaw angle).
Key wind noise parameters were the fore/aft length of mirror housing and the plan view angle of the mirror housing's inboard surface.
Key drag parameters were the fore/aft length of the mirror housing, the cross-section shape of the mirror pedestal, and the angle of the pedestal (relative to the wind).
