Abstract:
Cyclogiros have the possibility to provide hovering and achieve forward speeds higher than present day helicopters. Yet, due to the inherent unsteady aerodynamics, most of the research approaches have been based on limited experimental testing of computational fluid dynamics. However, and for a parametric analysis, it is important to provide analytic tools that can help in the preliminary design stage. In this work the complexity of the forward flight modeling will be described using an innovative approach. The present proposed model will be benchmarked against experimental and CFD results, further it will be used to propose rotor geometries for 3 working conditions.
