Autor: Gunther Wilke, Joëlle Bailly, Keita Kimura, Yasutada Tanabe
Publikováno v: 47th European Rotorcraft Forum
47th European Rotorcraft Forum, Sep 2021, GLASGOW, United Kingdom
International audience; A cooperation on the aerodynamic optimization of helicopter rotors has been formed by JAXA, ONERA and DLR. This work represents the conclusions drawn from the first phase: optimization of a hovering rotor. The HART-II blade is

Comparisons of Different Spatial Schemes and Limiters for Helicopter Flows
Autor: Gunther Wilke
Publikováno v: Notes on Numerical Fluid Mechanics and Multidisciplinary Design ISBN: 9783030795603
The requirements for a computational fluid dynamics solver to simulate the vortex-dominated helicopter rotor flows correctly are high. In recent years, many higher order methods and strategies have evolved to meet these requirements. This paper inves

Aerodynamic Performance of Two eVTOL Concepts
Autor: Gunther Wilke
Publikováno v: Notes on Numerical Fluid Mechanics and Multidisciplinary Design ISBN: 9783030252526
Today’s demand for urban mobility is constantly growing due to the demographic changes observed in metropolitan areas. New concepts such as electrical vertical take-off and landing (eVTOL) vehicles are currently emerging. Therefore an aerodynamic i

Variable-Fidelity Methodology for the Aerodynamic Optimization of Helicopter Rotors
Autor: Gunther Wilke
The design of helicopter rotor blades is a challenging task. On the one hand, there are the demanding simulations, which are a multidisciplinary endeavor. On the other hand, tools for parametric st...

Numerical airfoil catalogue including 360° airfoil polars and aeroacoustic footprints
Autor: Benjamin Faßmann, Gerrit Heilers, Manfred Imiela, Gunther Wilke
A methodology is presented for generating 360° airfoil polars and aeroacoustic characteristics by means of CFD and CAA. The aerodynamic procedure is validated against experimental data of the well-known airfoils DU-93-W-210 and DU-97-W-300. While a

Investigation of a simplified aerodynamic modelling technique for noise predictions using FW–H propagation
Autor: Jianping Yin, Gunther Wilke, Berend G. van der Wall
This paper addresses the influence of the elastic rotor blade deformation and the aerodynamic interference from the fuselage on the rotor aerodynamics, including rotor noise characteristics. A BO105 main rotor/fuselage configuration is chosen for the
