Aerodynamic Aspects of Propulsion Integration for Next-generation Commercial Aircraft
Doctoral thesis, 2023
The installation of next-generation high-bypass turbofan engines also poses a major challenge to the aviation industry due to the limited space beneath the wings and stringent ground clearance constraints. Over-wing installed nacelles can be a potential solution for this problem, instead of the customary under-wing mounts. In this thesis, a framework for engine/aircraft integration aerodynamic design has been developed. The over-wing configuration is compared to conventional under-wing mounts in terms of aerodynamic performance. A novel method for wing redesign in the presence of the nacelle is proposed and an engine placement study is carried out.
In addition, low-speed wind tunnel tests were conducted for two scale configurations. The first was a standalone powered nacelle whereas the second was a half-span powered over-wing mounted nacelle configuration. The aim was to investigate the impact of the engine power setting and angle of attack on the flow field for low-speed operating conditions.
