In previous research conducted, it was concluded that a reduction in the solidity at the tip of the blade of the fan via reduction of the number of blades leads to better aerodynamic performance and stall margin, as well as noise and flutter reduction. This study compares isentropic efficiency, fluid flow, and performance analysis between passage behavior of a low-solidity fan by reducing both number of blades and chord length against the original fan design, which has a solidity of 1.3 at the tip, and provides numerical results, with an emphasis on flow separation and boundary layer interactions. Performance graphs are provided for different operating ranges. Results show that the low-solidity configuration provides an improvement in isentropic compression efficiency and blockage while maintaining a similar operation range, at the cost of a slightly lower surge point.
