The purpose of this thesis was to illustrate the influence of the nacelle and pylon on aerodynamics of a new Very Light Jet design, using Computational Fluid Dynamics.
The objective of the first phase was to repair the existing CATIA model in order to facilitate the meshing process.
The second and third phase was to create two meshes: a mesh for the complete model (aircraft with nacelle and pylon), and a second for the aircraft alone.
The two problems have been solved at cruise conditions using Navier-Stokes equations with a second order accuracy.
The model complying with theory, the results have been then processed.
The analysis resulted in showing that shock waves were forming at the pylon, generating noise, vibration and more drag. Some improvements were discussed needing further investigation.
