Vacuum Pump Background • Problem: Blow-by • Solution: Crank case evacuation
Design Goals • Maintain optimum vacuum pressure • Flow more air than competitors • Must supply more power than requires to run • Reliable at 10000 rpm • Easily manufactured & maintained • Priced less than competitors
Design Obstacles • Space • Minimize Weight and Power • Shaft Design • Choked Flow • Bearings
Performance • Goal: To beat the leading competitor in every performance category • Peak volumetric flow at 10000 rpm is 128 ft3/min • Peak power draw at 10000 rpm is 8.8 HP • Predictable wear • Designed to maintain vacuum despite massive blow-by
