Figure # 1
When wing is moving against the wind, most of the air will hit the wing and make a sharp turn.
This is requiring great amount of energy. Airplane speed is reduced, and fuel consumption increased considerable.
Wing Cone Installed
When wing is moving against the wind, most of the air will not hit the wing directly and it flows smoothly upward. Airplane speed will increased and fuel consumption decreased considerable.
No ice will build up, even under icy conditioning.
When wing is in icy Conditioning, air mixed with water drops hit the wing and water turns into ice on the leading edge of the wing.
The air without the water drops ( dry air ) flows on the surface of the wing.
