Sinnige, T. (author), Ragni, D. (author), Eitelberg, G. (author), Veldhuis, L.L.M. (author)This paper presents an experimental assessment of the working principles of pylon trailing-edge blowing for the mitigation of the interaction between a pusher propeller and its associated pylon. The experiments were performed at the Large Low-Speed Facility of the German–Dutch wind tunnels (DNW–LLF), using a powered propeller model and an...journal article 2016

Sinnige, T. (author), Ragni, D. (author), Eitelberg, G. (author), Veldhuis, L.L.M. (author)Pylon-mounted pusher propellers suffer from installation effects due to the interaction between the pylon and the propeller. The impact of angular inflow on these installation effects was quantified at the Large Low-Speed Facility of the German-Dutch wind tunnels (DNW-LLF). Particle-image-velocimetry measurements showed that the pylon wake's...conference paper 2016

Sinnige, T. (author), Ragni, D. (author), Eitelberg, G. (author), Veldhuis, L.L.M. (author)The aerodynamic interaction e_ects characteristic of pusher propellers were studied at the Large Low-Speed Facility of the German{Dutch wind tunnels (DNW-LLF). A propeller model was positioned downstream of a pylon equipped with a trailing-edge blowing system. Surface-pressure transducers integrated into the propeller blades con_rmed the local...conference paper 2016

Yang, Y. (author), Sciacchitano, A. (author), Veldhuis, L.L.M. (author), Eitelberg, G. (author)During the ground operation of aircraft, there is potentially a system of vortices generated from the ground toward the propulsor, commonly denoted as ground vortices. Although extensive research has been conducted on ground vortices induced by turbofans which were simplified by suction tubes, these studies cannot well capture the properties of...journal article 2016

Yang, Y. (author), Zhou, T (author), Sciacchitano, A. (author), Veldhuis, L.L.M. (author), Eitelberg, G. (author)The aerodynamic operating conditions of a propeller can include complex situations where vorticity from sources upstream can enter the propeller plane. In general, when the vorticity enters in a concentrated form of a vortex, the interaction between the vortex and blade is referred to as blade–vortex interaction or BVI. The interaction may...journal article 2016

Veldhuis, L.L.M. (author), Stokkermans, T.C.A. (author), Sinnige, T. (author), Eitelberg, G. (author)In this paper we address a preliminary assessment of the performance effects of swirl recovery vanes (SRVs) in a installed and uninstalled tractor propeller arrangement. A numerical analysis was performed on a propeller and a propeller-wing configuration after the SRVs were optimized first in a separate process. The SRVs are essentially...conference paper 2016

Sinnige, T. (author), Malgoezar, A.M.N. (author), Ragni, D. (author), Snellen, M. (author), Eitelberg, G. (author), Veldhuis, L.L.M. (author)An experimental investigation was performed at the Large Low-speed Facility of the German-Dutch wind tunnels (DNW-LLF) to study the pylon interactions associated with pusher propellers. The aerodynamic and aeroacoustic effects of pylon trailing edge blowing and swirl recovery vanes (SRVs) were evaluated. The pylon installation increased the...conference paper 2015

Wang, Y. (author), Li, Q. (author), Eitelberg, G. (author), Veldhuis, L.L.M. (author), Kotsonis, M. (author)Swirl recovery vanes (SRVs) are a set of stationary vanes located downstream from a propeller, which may recover some of the residual swirl from the propeller, hoping for an improvement in both thrust and efficiency. The SRV concept design for a scaled version representing the Fokker 29 propeller is performed in this paper, which may give rise...journal article 2014
