THE AIR RESISTANCE OF MOTOR VEHICLES

TESTS ARE PRESENTED OF THE AIR RESISTANCE OF MOTOR VEHICLE BODIES, INCLUDING A STUDY OF TEST METHODS AND AERODYNAMIC CHARACTERISTICS OF SOME SIMPLE BODY FORMS. WIND TUNNEL TESTS OF HIGHWAY VEHICLES ARE COMPLICATED BY THE FACT THAT A ROAD SURFACE MUST BE PROVIDED. TESTS WERE MADE BY FOUR METHODS: (1) MODEL FREE, NO ROAD SURFACE PROVIDED; (2) USING A FLAT PLATE AS THE ROAD SURFACE; (3) USING THE FLAT PLATE WITH PLATE WITH BOUNDARY LAYER PARTIALLY REMOVED; AND (4) REFLECTION METHOD, USING DUPLICATE MODELS PLACED BOTTOM TO BOTTOM. THE DATA SHOWING THE PERCENTAGE OF IMPROVEMENT DUE TO STREAMLINING ARE FAIRLY CONSISTENT WHEN MEASURED BY ALL FOUR METHODS. /AUTHOR/
