Abstract
This dissertation has considered various ways in which sound is generated in an aeroengine, with a particular focus towards the sound generated by blade-blade interactions within the engine. We have constructed semi-analytic solutions for certain interactions; gust-aerofoil interaction in steady, subsonic, uniform and shear flows; and sound-aerofoil interaction in steady, subsonic uniform flow. To find these solutions we had to separate the solution domain into various asymptotic regions wherein different behaviour dominated the production of sound. The regions were matched using Van Dyke’s matching rule.
