DougHi All correct me if I am wrong. I also thought no way untill I stopped and really thought about it. to create lift there must be a downward flow of air. without a downward flow of air there can be no lift. in autorotation there is a downward flow of air creating lift otherwise we would just drop out of the air.
Are you saying/thinking for a fixed wing there must therefore also be a “downward flow of air”? I don’t think that’s true. For both there’s an upward vector of lift, caused by the aerodynamic forces at play.
Again, I don’t believe there is a VRS for a gyro and have seen no credible source suggest otherwise.
