MEASUREMENT OF THE PROJECTED FRONTAL AREA OF VEHICLES - A NEW CONTOUR-TRACKING LASER DEVICE IN COMPARISON TO OTHER METHODS

The determination of a vehicle's drag coefficient requires measurements of its aerodynamic resistance and its projected frontal area with high measuring accuracies. The paper gives a description of optical methods for measuring projected areas and details a laser reflection system which operates on a principle similar to that of a light-barrier system but in a reflection mode. The principle of the measuring method, its advantages and the results of measurements on test objects are detailed. For the covering abstract see IRRD 819832.
