Installation Aerodynamics of Open Rotor Engines: An Overview of The LuFo IV Project OPERO

Kurzfassung

This paper presents an overview of the main results pertaining to the aerodynamic aspects investigated within the project OPERO. In this project, numerical investigations of aerodynamic installation effects of CROR engines were performed at low and high speed flight conditions for semi-installed and fully-installed pusher and tractor arrangements. The numerical results were compared to experimental results to assess the accuracy of the time accurate and the steady computational fluid dynamics (CFD) approaches for the simulation of propeller systems implemented in the DLR TAU Code.
