Abstract
The helicopter ran with a fixed value of the rotation velocity, which posed a limitation in forward flight, in order that the rotor blade tip stayed at the subsonic regime. This limitation caused high energy consumption. In our research, we tried to solve that problem to optimize energy consumption and improve the helicopter’s aerodynamic performance in hover and forward flight. To reach our objective, we acted on the rotor structure, in order to have a rotor with a variable diameter. Several simulation tests were done at different values of the rotor diameter in order to have an idea of the optimal value of the rotor diameter in both forward and hover flight. To achieve that work, we proceeded with the Computational Fluid Dynamics (CFD) approach. From the CFD analysis, we extracted the evolution of the thrust force and Mach number in both hover and forward flight and compared them to get the final result vision.
