Some recent fundamental studies relating to the lubrication of helicopter transmissions are presented and their implications for future oil development discussed. The resulting enhanced understanding of lubrication mechanisms has shown that the real potential exists both for improved performance and for ability to cater for higher temperatures, by means of the formulation and use of improved transmission oils. If such benefits are recognized and if the new knowledge is correctly applied, there is no reason why helicopter gearbox reliability should not be appreciably improved by the end of the decade.
