To ensure the flawless performance of gasturbine engines it is essential to have a full understanding of the influence of ester base fluids on elastomers, which are used as seals in these engines. This paper describes the development of a simple model to relate the chemical structure of ester base fluids and elastomer swell properties. It's validity has been checked experimentally using a variety of elastomer seals and lubricant base fluids.This model offers a guideline in the selection of esters for gasturbine engine oils, enabling current or new military and civilian specifications to be met.
