Pardon my ignorance. Is this that different from a helicopter besides having walls? Does this mechanism serve a different purpose?

  A helicopter uses a rear rotor to counteract the main rotor rotation. Here he is using thrust vectoring to perform that task.

    Ah, thanks! Some helecoptors also just use a second main rotor spinning in the opposite direction instead right? Would that not be sufficient? Sorry if it's covered in the video I've only seen the beginning so far.

      Yes but he only had one fan. Just a rotating ring mounted somewhere would help too. But not as much fun I guess :-)

    This is visible in the very last scene where it automatically tilts its blades to counteract the rotation induced by the accelerating propeller.
