US Patent 7810391 Aerodynamic hood lift and deflection measurement device

An aerodynamic hood lift deflection measurement device includes an airfoil body mounted to a front vehicle fender such that a portion of the airfoil body held over the vehicle hood. A laser measurement device is secured to the airfoil body in a position so as to be directly over the vehicle hood. The airfoil body is mounted at an angle such that a length direction of the airfoil body is parallel to an air flow direction. The resultant disruption of the air flow surrounding the vehicle hood is minimized due to the shape and positioning of the measurement device.
