Optimizing a Fuel Pump Impeller for Cavitation and Efficiency

Advanced Design Technology used TURBOdesign Suite to redesign the fuel pump impeller of a major supplier to the aerospace industry.

The client was suffering from significant erosion to their existing aero-engine fuel pump impeller due to cavitation.  ADT used TURBOdesign1 to optimize the impeller to reduce cavitation while maintaining and acceptable level of efficiency and performance. 

Key elements of the redesign included fitting the impeller to the existing casing and meeting the required head at both take-off and cruise conditions.
