Hello Jens
Are we introducing the "Coanda" effect on the spoon? The wing behaves more like an inclined plane (alpha) than a NOTAR. Redirecting airflow is not much more complex than this, although it is possible to introduce more complex considerations. I appreciate your introduction of the hovering helicopter; moving air around keeps us all in business. Likewise, a simplistic view of muscle kinesiology is perhaps helpful. The far end of the discussion involves the tax on all movements, entropy. A stable or "unaccelerated" airframe in flight resists the acceleration of gravity in its simple expression. Can we call the resistance against 16ft/sec/sec work? I would. Similarly, forward motion is put in the bank. This is the interesting part of the hover. Work is being "done" on the air. The third law doesn't need name tags, it all adds up in the end.
The "four vector" diagram is wanting a fifth, where is the "lift" vector pushing down on the horizontal Stabilizer? There are others. Thanks for your comments.
rgds, bill
