Doesn't need to be. The advancing rotor blades accomplish the same thing as a wing.Point is the Raider doesn't completely unload..Because you have an advancing blade on both sides at all times you still have lift on both sides. The rigid rotors reduce flapping of the retreating blade (which loses more lift the faster you go). Doesn't need a wing. Both Karem's design and the AH-56 have the wing to unload the rotor and eliminate roll-off in the direction of the retreating blade.Are the Sikorsky blades completely "unloaded " in winged based flight? Where are large wings. Do they use no main rotor for completely horizontal flight?You said, "The manufacturer has stated the design eliminates retreating blade slowing."
That's not what they do. The retreating blade is going to have reduced relative motion to the airflow as you speed up no matter what. What they're doing is eliminating its impact. The is what Sikorsky X-2 technology (and the previous XCH-59) does (by having a lifting blade on both sides combined with a rigid rotor). It's what the AH-56 did.
