Abstract
[en] Pressure, temperature or swirl are different types of distortion that can appear on engines due to different reasons. All them modify the stability and performance of the engine because rotating stall and surge may appear for pressure and temperature conditions, while the angle of incidence changes in the case of swirl distortion. The objective is to understand the behaviour of the engine under these conditions to avoid stability problems.
