That only (intuitively) explains lift generated by a positive angle of attack. As shown here, you can get lift with a flat angle of attack: https://www.wolframa

- smusamashah 5y agoThe upside is curved pushing air upwards reducing the pressure hence generating lift from below. Isn't it just that?
- hollerith 5y agoIf the plane is pushing the air up, then by Newton's third law, the air is pushing the plane down. Also, pushing it up would not reduce the pressure of a parcel of air.
