A study of seal lubrication in an aerospace fuel gear pump including the effects of roughness and mixed lubrication
The project was supported by Aero Engine Controls (part of the Rolls-Royce Group). Current legislation (e.g. EU REACH) rules out the use of lead traditionally applied to the end faces of gears in aircraft engine fuel pumps to minimise wear. By using advanced elastohydrodynamic analysis the paper has demonstrated to the company how careful geometrical design can give thicker fluid films and thereby avoid the need for lead. The PhD student on the project has been employed by Rolls-Royce, and the project led to further financial support from the company for a £423k EPSRC grant EP/G06024X/1. martin.yates@aeroenginecontrols.com
