An airfoil generates lift primarily through its shape and angle of attack. As air flows over the curved upper surface of the airfoil, it accelerates, resulting in lower pressure above the wing compared to the higher pressure beneath it. This pressure difference creates an upward force known as lift. Additionally, the angle of attack, or the tilt of the airfoil relative to the oncoming airflow, further enhances lift up to a certain point before causing stall.

How airfoil design works?
An air foil works with thrust, when you creat thrust the air foil creats a lift. The lift is created by the speed of the air being split in half, creating a "zero gravity effect" (which is the lift)
Why can't a hot air balloon float in outer space?
A hot air balloon requires air to generate lift. In outer space, there is no air or atmosphere, so there is nothing for the hot air balloon to displace to generate lift, causing it to be unable to float.
Why cant a helicopter work on the moon?
A helicopter requires air to generate lift from its rotors. Since the moon has no atmosphere, there is no air for the helicopter to push against and create lift. This makes it impossible for a traditional helicopter to work on the moon.
What is true about airplane and rocket flights?
Only one requires air molecules to generate lift.
What statement about airplane and rocket is true?
Only one requires air molecules to generate lift.
What statements about airplane and rocket flight is true?
Only one requires air molecules to generate lift.
Why cant an aeropane fly into space?
Because planes need air pressure against their wings to generate lift.
Why doesnot an air craft fall on the ground?
Because the wings generate lift as long as the aircraft is in forward motion
How does an air foil wing create lift?
An airfoil wing creates lift by having a curved shape on its upper surface and a flatter shape on its lower surface. As the wing moves through the air, the air pressure above the wing decreases, creating lift due to the pressure difference between the upper and lower surfaces of the wing. This lift force helps to keep the aircraft airborne.
How do airplanes takeoff?
Airplanes need to generate lift in order to take off and fly. The way they do this is to go fast enough on the ground so that the air passing over the wings generates lift in accordance with Bernoulli's principle. When sufficient speed is attained to generate the necessary lift, the plane will fly.
Lift must be than gravity in order for a plane to stay in the air?
Lift generated by the wings of a plane counteracts the force of gravity pulling it down, allowing the plane to stay in the air. For a plane to achieve lift greater than gravity, it must generate enough thrust through its engines to maintain forward motion and generate sufficient lift from its wings to overcome the force of gravity.
How do helicopters stay in the air?
Helicopters use the same principle as aeroplanes to produce lift, the main difference is how they employ it. As with planes a helicopter uses a aerofoil to produce lift by passing air over the top of a foil faster than under it due to the geometry of the foil. The pressure difference between the air flowing fast over the top of the foil(low pressure) and slow under the foil(high pressure) results in an upwards force on the rotors of the helicopter, the pilot can essentially control the amount of force(or lift) acting up by changing the speed of the respecting flows of air. This is done by changing the angle with which the aerofoil cuts through the air. The spinning of the rotors produces a torque, which if left unbalanced would result in the helicopter spinning like a top and not producing enough lift. This torque is countered by a tail rotor usually or a contra rotating propeller (e.g. the chinhook)
