slowrotor,
The specific idea may not (or may) be practical however the intent was serious.
We probably agree that the wing is the most efficient method for forward flight, and particularly for fast forward flight. I am just trying to think of wild ideas that might be the foundation for, or the inspiration for, a short-duration VTOL addition.
The above is an attempt to utilize the wing as a barrier between a large and controllable, short-term pressure differential.
