Using the angular momentum of a spinning rocket engine nozzle to eject fuel is proposed as a potential efficiency improvement. However, concerns are raised that imparting spin to the exhaust flow could reduce overall engine efficiency. The primary benefit identified would be to create counter-rotation, which could simulate pseudo-gravity for the vehicle. Despite the innovative thinking, the practicality and effectiveness of this idea remain questionable. Overall, the discussion highlights the complexities of optimizing rocket propulsion systems.
