What is the airfoil on a helicopter?

Why is that helicopter has an inverted airfoil in the tail section?

An inverted airfoil on the the horizontal stabilizer of an airplane will stabilize the aircraft along the horizontal axis in forward flight.

Why does the rotors spin on an helicopter?

The rotor blades on a helicopter work the same way as wings on a fixed wing aircraft. The air passing faster over the top of the airfoil generates lift. Helicopter rotors spin so that the lift is generated without having to have forward airspeed like a fixed wing aircraft.

What is the difference how a helacopter creates lift and an airplane?

They both utilize airflow over an airfoil. The helicopter moves the airfoil (blade) by spinning them, as air passes around the blade it creates lift. An airplane uses thrust from the engines to push the airfoil (wings) forward through the air, the air then flowing over(lower pressure) and under them (higher pressure) produces lift.

Is airfoil a good conductor?

It depends on what the airfoil is made of.

How do you use Airfoil in a sentence?

the ground is an type of airfoil

Why an airfoil is important for flight?

airfoil is important beacause it boils

What is the revolving aerofoil used to provide lift or to control a plane in flight called?

I'm not entirely sure what you are trying to ask, but because of your usage of the term "revolving aerofoil," I will explain a simplified theory of operation of a standard helicopter to answer your question.The revolving Airfoil used to provide lift and most control of an aircraft would apply only to a Helicopter, because the revolving Main Rotor is the "wing" of this type of aircraft (as opposed to a non-rotary airfoil on a fixed-wing aircraft). Without getting into detail on the cyclic and collective controls that the pilot uses, let us just understand that the Airfoil rotates on the helicopter and when the pitch (the angle of the blade in respect to the flow of air) of the blades are increased, the main rotor will provide upward lift for the helicopter. Through the use of the pilot's controls, the blade pitch can be manipulated in such a way that the helicopter can be pitched forward or backward, and banked (rolled) to the left or the right, as well as providing upward lift. However, because of the torque generated by the rotation of the Main Rotor, the Tail Rotor is designed to counteract the tendency of the entire fuselage to spin opposite of the Main Rotor direction of rotation.In summation, the Main Rotor is a revolving airfoil that generates lift while also giving pitch and bank control to the helicopter. The Tail Rotorprovides yaw control. -APTech

How do you control drag from increasing on helicopter?

Drag cannot be eliminated because drag always acts parallel to the relative wind. We can control by purchasing or using the right airfoil on the aircraft. An airfoil with smooth surface produces more lift than one with a rough surface. A rough surface creates turbulence, which reduced lft and increases drag.

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.

What is the shape of a helicopters wings?

The helicopter main rotor blades have an airfoil shape like an airplanes wing. The entire blade can also be angled by the pilot,through the rotor head. This angle makes it fly or lift.

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
