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 do aircraft fly?
There is two categories of aircrafts, the aerostats (lighter than air) and the aerodynes (heavier than air). -Aerostat: the aerostat uses buoyance to float in the air in much the same way that ships float on the water.They are characterized by one or more large gasbags or canopies, filled with a relatively low density gas such as Helium, Hydrogen, or Hot air which is lighter than the surroundind air. When the weight of this is added to the weight of the aircraft structure, it added up to the same weight as the air that the craft displaces. -Aerodyne: To fly it must move forwards through the air ,this movement of air over the aerofoil shape deflects air downward to create an equal opposite upward force, called lift, according to the Newton's third law of motion. Aerodyne flight: The best method to answer this question is thru the use of the lift formula: L= (1/2p) (V2) (S) (CL) 1/2p (pronounced rho) is basically the density of the air. Cool dense air provides better pressure in creating lift. V2 is the velocity of the airfoil flowing thru the air. Higher velocity creates more lift except when reaching velocities that exceed the sound barrier disrupting laminar flow over the airfoil. S is the surface area of the airfoil. A larger surface area creates more lift. It may also create more weight which would increase the need for more lift. CL is the coefficient of lift. Without getting to complicated, this is basically the efficiency of the airfoil design at an angle of attack. Angle of attack is essentially the angle between the chord line of the airfoil and air flow direction. When air flows over the airfoil, the design of the foil seperates the airflow into an area of low pressure over the camber of the airfoil, and an area of high pressure below it. Obviously the difference between the two areas will cause the movement of the airfoil in the direction of low pressure thus creating lift. Their are four forces at work in the creation of lift: Lift - Explained above Thrust - The force required to move the craft forward to create velocity of airflow. Drag - The force created from the creation of lift and thrust. Parasitic, Induced, and Profile drag are the different types of drag working against lift. Weight / Gravity - What must be overcome by lift.
What are 3 types of non-volcanic types of eruption?
the two types of volcanic eruptions are magma and lava
What are the types of reproduction?
The types are two - sexual and asexual.
How many types of reaction names?
5 types of reactoin are there
What are different types of boondoggles you can make?
diffent types of boondoggles
How do you use Airfoil in a sentence?
the ground is an type of airfoil
Is airfoil a good conductor?
It depends on what the airfoil is made of.
What is the airfoil on a helicopter?
The rotor blade is the airfoil on helicopters.
Why an airfoil is important for flight?
airfoil is important beacause it boils
What is subsonic airfoil?
which airfoil must produce the lift with less than one mach number . that is called sub sonic airfoil...... Another answer would be : an airfoil designed to perform below the speed of sound.
How does circular arc airfoil work?
Just like any other airfoil.
What is symmetrical airfoil?
A symetrical airfoil is an airfoil that has the same shape on both sides of its centerline and in this type of airfoil : the centerline is thus straight the chord line is the center line the maximum camber is zero the camber ratio is zero
What does an airfoil look like?
A simple concept in aeronautics is about airfoil to know the shape of airfoil before speaking about about the shape of airfoil i would prefer you to know about airfoi the advantages of using airfioil is $it is the most aerodynamical shape ever designed $if you look at a planes planes wing closely you can notice the shape of airfoil $
What is the difference between airfoil profile and airfoil section?
The difference between airfoil and airfoil section is that airfoil is a structure with curved surfaces designed to give the most favorable ratio of lift to drag in a flight, it is used as the basic form of wings, fins, and tailplanes of most aircraft. An airfoil section is the cross- sectional shape or profile of an airfoil. I studied that in sixth grade for a model plane that I did a report on. Researching into things that aren't required can help put you farther into life's riches. Hope I helped.

What is the purpose of an airfoil?
An airfoil is a 2-dimensional shape that defines when built and inserted in a moving fluid will create a "Lift". The airfoil or wing can be used to turn ships or make an airplane fly.
Why do flow separates over an airfoil?
Because of a change in the angle of attack. When you exceed the critical angle of attack there is not enough wind passing over the airfoil and therefore disrupting lift, the airfoil stalls.
