Abstract
In order to retrofit an existing aircraft with hydrogen propulsion, the nacelle size has to increase to house all propulsion components. This thesis investigates the aerodynamic effects of increasing the nacelle size through load balance measurements and particle tracking on a simplified geometry.
Based on these measurements, it can be found that the nacelle enlargement causes additional drag through more frontal area as well as additional induced drag through vortices. It also highlights changes in effective angle of attack at the wing sections right next to the geometry.
