A major cause of noise at airports are the run-up tests conducted after engine maintenance. The acoustic enclosures currently used to alleviate the problem are expensive and not very effective and can only be used during favorable wind conditions. Delays and complaints are commonplace. The reason why engines on stationary aircraft are at least twice as noisy as engines in flight is investigated and the findings used to propose more efficient and cost effective methods of noise reduction. This approach has also revealed a possible cause of premature and unexpected failure of combustors and turbines.
