Investigation of Total Pressure Distribution at Aerodynamic Interface Plane of an “S-shaped” Air Intake at Sideslip Condition

摘要

An appropriate performance of an air intake is a critical parameter for the best flight of an aircraft using a jet engine. Since then it is expected to ensure of this performance clearly, otherwise, the engine could probably have difficulties in breathing due to lack of proper functioning of the air intake. An Unmanned aerial vehicle - like any other aircraft – takes over a variety of flight regimes, since then the analysis of intake performance should be done in each condition. Due to the necessity of utilizing a jet engine in some of UAVs, it has been set to investigate the performance of an “S-shaped” air intake in the subsonic flight regime using numerical methods. Regarding to the lack of a professional experimental apparatus and the high level of knowledge required in the experiments the results then have to be compared and to be validated with experimental and numerical data obtained in previous similar efforts accomplished by aerodynamic and propulsion scientists all over the world.
