In new projects of gearboxes for aeronautical application performed by FIAT AVIAZIONE, the specified requirements have become more and more severe. This paper deals with the most important points out by these specs, such as fail safety, reliability, low vibration and low noise, high working temperature, invulnerability and maintainability, of course combined with a low weight characteristic. A detailed analysis is carried out to identify the guidelines for obtaining the best compromise among the above listed requirements, by applying a proven philosophy. The advantage of a reliable system capable a detecting failures in progress within the gearbox is also underlined as it can be a key point in defining the final design resulting from the optimization procedure.
