Abstract： In order to solve the problems of the effect of high-speed aviation gear pump clearances on the effciency，a flow field simulation was established and combined with theoretical model analysis to study the effects of diferent radial and end face clearances on internal leakage and eficiency，as wellas to explore the optimal radial and end face clearances at different speeds，and establish multiple groups of orthogonal experiments for verification.The results show that as the speed increases，the optimal end face clearance sizes also increase，and as the speed increases，the effect of the clearance sizes changes on the eficiency of the fuel gear pumps decrease.
