Abstract
In 2019, JAXA, ONERA and DLR have joined forces to cooperate on the optimization of helicopter rotor blades. The cooperation aims to further understand rotor aerodynamics and enhance and validate the tools for simulation and optimization of the planform and twist of rotor blades in various flight conditions. After optimizing the required power in hover and high advance ratio flight separately, a combined optimization of both was presented in 2023. This work presents the challenges with modelling the descent flight condition to capture the noise generated by blade-vortex interaction and means to reduce this phenomenon. The aim is to identify suitable means and methods for the acoustic optimization of helicopter rotors in descent flight.
