Draw a beautiful antique cabinet with different shelves. Lift = wind thrust (and speed), and Drag = friction and power loss. The tapered shape follows Bernoulli’s principle, forcing the air to move faster over the curved ‘top’ of the blade, reducing pressure and creating lift or thrust from ‘below’. It is just not as simple as that though. Early jet engines use what are called narrow chord fan blades that are typically made of solid titanium.
