The results of aeromechanical design of a large-scale fan stage model for a low-noise high-performance fan prototype for an advanced civil aircraft geared turbofan with an ultra-low tip speed and a high bypass ratio are presented. The stage is designed for tests in the anechoic chamber of the CIAM’s C-3A special acoustic test facility.
