HIGH-FIDELITY flow solvers for aeroelastic applications require the use of computational
meshes that deform as the structure is being displaced. High-aspect-ratio wings increase the …

This paper gives an overview of CFD techniques developed and used at ONERA for
rotorcraft applications. First, the complex multidisciplinary environment around helicopters …

This work exploits the ONERA 7A rotor wind tunnel test for comparison with concurrent
simulations at the US Army and ONERA. Rotor airloads and structural loads are predicted by …

The state of the art of weak fluid-structure coupling for rotors in forward flight at DLR is
presented. The coupling procedure is based on the DLR rotor simulation code S4 and the …

The ONERA 7A rotor wind-tunnel test data are investigated to assess the accuracy of
analytical tools in the calculation of rotor airloads and structural loads. Comprehensive …

Within the frame of the long term French-German CHANCE program, the Chimera method
has been developed and enhanced particularly for helicopter applications. This paper …

Two techniques aiming at solving the fluid-structure coupling problem for a helicopter rotor
in forward flight are described and compared in this article. The first one is the weak …

The complexity of the kinematics and aerodynamics of rotors is a challenging problem for
achieving accurate modeling for prediction of rotor loads. The present paper describes an …

This paper presents the findings of an investigation into the aerodynamic characteristics of a
representative Australian Defence Force (ADF) helicopter fuselage. Numerical and …

The simulation of the aerodynamic interactions between the different parts of a helicopter
becomes more and more important for the understanding of the complex flowfield and the …
