Keesom, Thomas (author)The potential for a correction by Rethorst for Vortex Lattice Methods (VLMs) exists to improve Longitudinal Static Stability predictions when applying the Rethorst correction to a slipstream engulfed horizontal stabilizer. The Rethorst correction has already proven to result in accurate lift predictions in VLMs for an isolated wing in a...master thesis 2023

Chance, Yannick (author)Propellers were the first means of powered propulsion for aircraft. However the development of propellers stalled due to the growing interest in jet propulsion. Due to the growing interest in more fuel efficient and environmentally responsible aviation, propeller research is currently seeing a resurgence. <br/><br/>Wingtip-mounted propellers are...master thesis 2021

Willemsen, Roger (author)Wingtip-mounted propellers have the ability to enhance the propeller-wing system performance. For inboard-up rotating tractor propellers, the swirl in the propeller slipstream can be used on the wing to reduce the influence of the wingtip vortex, decreasing drag. Furthermore, lift is enhanced by increasing dynamic pressure and angle of attack...master thesis 2020

Stokkermans, T.C.A. (author)This research is on the aerodynamics of propellers in interaction. As a propeller is dependent on the flowfield it encounters, any disturbance in that inflow results in changes in loading on the propeller. This can result in propulsive efficiency changes and affect stability through generation of in-plane forces and out-of-plane moments. The...doctoral thesis 2020

Mourão Bento, Hugo (author)With the goal of decreasing the environmental impact of aircraft, ducted propellers emerge as an efficient propulsive alternative. Ducts are able to increase the thrust to power ratio of a propeller system by both producing thrust and/or lowering tip losses of propellers. In this thesis, RANS CFD simulations were used to analyse the possible...master thesis 2019

Marcus, Pepijn (author)The research objective is to analyze the aerodynamic interaction effects and quantify the performance of over-the-wing propeller systems. To achieve this objective, two wind tunnel experiments have been performed to characterize the most important aerodynamic interaction effects of a single propeller installed over-the-wing. Results feature wing...master thesis 2018
