Hello. I'm calculating the different parameters of a turbine design but I have some trouble with the solidity. The solidity near the hub exceeds 100%, but is an average of ~27% for a 6 bladed turbine. I'm just wondering if anyone has had experience in turbine design and if +100% solidity is normal (i.e. normal for blades to overlap each other near hub) or not. Any help would be much appreciated.
