Hi JETLag03, answering to your questions
Then further questions raised their ugly heads, the rotor disc loading, is this calculated to include or exclude the rotor bar swept area, and same question for the blade loadings, so, I played with an excel spreadsheet out of curiosity to see what magnitude of difference with and without the hub bar made.
You have to consider the hub bar included all the time, like part of the blade.
The radius is the sum of the blade length plus half of the hub bar length. It is the distance from the center of rotation shaft to the tip of the blade, with the disc flat, no conicity is taken in account.
