Could an aircraft have a spinning wing as a helicopter rotor at low speeds which stops spinning at high speeds to act like an airplane wing? The tail-rotor would turn 90 degrees and become a pusher propeller when this happens.
This is different than tilt-rotors or tilt-wings because in my case the rotors/wing switches from vertical thrust to vertical lift instead of switching from vertical thrust to horizontal thrust.
There must be some serious flaw with my design, and stopping the rotor fast enough to avoid retreating blade stall may be a problem. Maybe we could set the collective to almost zero and have a short period of low-g while we transform (but not negative g which would be bad)?
Helicopter blades have shorter chord than airplane wings which may force us to get a not-so-good compromise.
