Analysis and Optimization of a Subsonic Intake for Civil Aircrafts

In subsonic flight, the intake of a civil aircraft has a primary role in the generation of thrust, because the airflow behaviour, upstream and inside it, influences the overall performance of the engine. In this thesis, a CFD model is built up to investigate and describe this kind of airflow: wind tunnel test data and 1-d gas dynamics are used to validate it, so as, at the end, to optimize its shape, in order to improve drag and pressure recovery performances.
