The effect of excluding the nacelle in tip-mounted propeller research can be modelled with Computational Fluid Dynamics (CFD) to quantify this effect on the wing performance and flow measurements. For this, the performance parameters of the wing in terms of lift and drag are analysed. Also, swirl angle and total pressure in the wake is investigated to understand the vortex behaviour. This is all done for a configuration set without a propeller, and also with a propeller installed in the form of a disk model.

Last January, yet another attempt to reach consensus on the growth of Schiphol has failed. Schiphol, KLM and other large airliners request a growth of 10,000 extra flight movements per year, while habitants, governors of municipalities and province and environmental organisations request a growth stop until 2023. The main arguments are noise disturbance in the surroundings of Schiphol and the negative effects of aviation on the local and global environment 1. In order to stop the limitations on aviation growth, structural changes will have to be made in the industry. One of the proposed solutions is to remove the conventional landing gear and make use of a ground based powered system to perform the landing and take-off. Firstly, the intended result is a reduction in fuel emissions due to the weight reduction of the aircraft: a conventional landing gear counts for approximately 4% of the maximum take-off weight of the aircraft. Secondly, the use of a ground based powered system provides for the opportunity to reduce noise pollution during take-off and landing. These two advantages are exactly tackling the two major issues that prevents airports like Schiphol, from growing...
