title = "Aerodynamic investigations on a helicopter fuselage",
abstract = "The flow around a helicopter fuselage is investigated experimentally and numerically in forward flight condition. The focus is set on the flow phenomena occurring on the lower backside of the fuselage, where massive flow separation and vortex formation appear. The experimental part of the investigation includes force measurements, surface pressure measurements and the capturing of the velocity field in the wake of the fuselage. Two model mount systems are used to investigate the influence of the model suspension system on the flow around the fuselage. The numerical investigations cover a grid study and the comparison of the simulation with experimental data. The experiments showed that the model mount has a significant influence on the flow around the fuselage, especially on the separation and vortex formation at the backdoor section. The comparison of the numerical and experimental data exhibits a good agreement of the aerodynamic loads as well as of the flow structures in the aft body. The analysis of the complementary experimental and numerical data provides a detailed view of the flow characteristics at the fuselage afterbody.",
