Abstract

This review paper examines the aerodynamic simulation methods of helicopter rotor. First, the classification of the researches carried out in the field of helicopter rotor blade geometry and the field related to each one has been briefly explained. In the following, the material used in helicopter rotor blades is evaluated. Then, considering the emergence of computers and their ability to analyze since the 1970s, the important researches conducted from this date until 2023 have been examined. With the conducted investigations, it can be seen that with the change of materials used in making blades from metal to composite, and as a result of better malleability and more freedom of action in making various shapes, there has been an increasing interest in improving blade geometry among helicopter manufacturing companies and researchers. This confirms the need to improve helicopter rotor simulation methods. At first, these methods were used only for the purpose of analyzing and evaluating the performance of rotors, but with the advancement of computers and commercial software, these simulations were moved towards optimization processes.
