Abstract

It is demonstrated that the unstructured, hybrid method of the MEGAFLOW project is capable to compute accurately the engine-airframe installation drag for several engine types although drag differences for varying engine positions can be very small. Results are presented for the DLR-F6 and the DLR-Alvast configurations with through-flow nacelles and powered engines. Verification by grid refinement as well as validation with wind tunnel data completes this investigation.
