The paper reports investigation of the aerodynamic performance of different hub fairing shapes and compares them to the baseline hub. The investigation relies on stationary RANS simulation of air flow past the GRC common platform fuselage and a gener

In this paper two approaches are investigated to reduce the parasite drag of a helicopter. The first approach is to optimize the surface of the fuselage back door. This is done by applying an automatic, adjoint-based optimization chain; developed by

An investigation was carried out using the flight mechanics tool HOST weakly coupled to the RANS solver FLOWer to simulate the flow around helicopter configuration under different flight conditions. The configuration considered was a wind tunnel mode
