an object shaped to produce lift by the bernoulli principle when moving in a fluid
Emory Davis
Airfoils are aerodynamic shapes that are designed to produce lift when air flows over them. They are commonly used in aircraft wings, propellers, and wind turbines to generate lift or thrust. The shape of an airfoil allows it to create a pressure difference between the upper and lower surfaces, resulting in lift.

Types of an airfoil?
there are many types of airfoils but in two different categories. They're Conventional and Laminar Airfoils. They each have many designs. Such as the conventional airfoils have six basic designs of airfoils.The Laminar Airfoils are : -

How are the airfoils of a stunt plane and fighter jet different?
The airfoils on a stuntplane are meant to make it extremely manueverable at low speed, so the control surfaces are much larger. Jet fighters need less movement.
Why use anhidral airfoils?
To get the control surfaces into air that has been undisturbed by the fuselage.

What is difference between coefficient of lift of 2 exactly the same airfoils one made of Wood and another made of Steel?
The weight.
How do the military make square parachutes?
The T10 and T10 Modified chutes are not square. What you're referring to is the airfoils used by freefall and HALO parachutists. Those are not made by the military - they're sourced from civilian companies who manufacture parachutes for civil parachutists. What the specific specs are for the military contract airfoils.. that information isn't made available to the public.
How is energy formed from wind?
Wind turbines convert Kinetic energy into Mechanical energy. Wind turbine rotors are airfoils. In addition to the wind hitting them, the aerodynamic effect increases their spin. The wind has kinetic energy. The airfoils have mechanical energy. They are connected to an electrical generator, essentially tightly wound wire and magnets, that turn the mechanical rotation into electricity.
