High Bypass Turbofan Component Development. Amendment I. Small Fan Redesign

摘要

The aerodynamic and mechanical redesign of a small, high through-flow, single stage fan rotor to increase its design-point airflow rate was completed. Since the original design exhibited excellent aeromechanical characteristics, the redesign was confined to changes in the blade meanline angle; parameters such as maximum thickness-to-chord ratio, thickness distribution, aspect ratio, and solidity being unchanged from the original design. Procurement of the redesign fan rotor has been completed on schedule, thus fulfilling the requirements of this contract. (Author)
