I am curious about a method to enhance the efficiency of passenger aircraft during cruise speeds by integrating treadmill-like structures on the fuselage and beneath the wings without changing the original shape of the aircraft and the airfoil.
These structures, designed to move with air friction without altering the traditional airfoil shape, aim to decrease drag and increase lift. The idea is that as the structures move with air friction, the relative speed between the surfaces and the air decreases, leading to reduced drag induced by the friction.
Placing these structures under the wings could potentially augment lift by increasing pressure due to the decreased relative speed.
Additionally, even these structures do not create any lift or reduce the drag, we can produce kinetic energy with these moving structures, which otherwise wasted in the form of heat energy due to friction between the air stream and the wing surfaces.
I seek insights from the Engineering Stack Exchange community on the feasibility, potential benefits, challenges, mistakes associated with this concept and the reasons why this method will not work, emphasizing its potential to improve fuel efficiency without requiring significant alterations to current aircraft design.
