The paper presents results of aeromechanical design of a few fan models for an advanced civil geared and direct driven turbofan with reduced and ultra-low tip speed and high bypass ratio. This work aimed at creation a potential for optimal design and numerical modeling of processes as well as experimental investigations of aerodynamic and acoustic features of new fans at C-3A CIAM test facility
