Abstract
We discuss the growing importance of forms of aerodynamic noise other than classical jet noise in the modern gas-turbine engine. An experiment is described in which, on a model scale, the sound-generating capabilities of a flow spoiler within the environment of a pipe have been studied. A selection of results is presented. These show some of the principal findings of the study and the appearance of a correlation scheme for spoiler noise based on the total pressure drop across the spoiler.
