- A plane flies when all four forces – lift, weight, thrust and drag – work together. DID YOU KNOW? A plane’s ability to fly can be explained through a scientific theory called Newton’s Third Law of Motion. This law states that ‘for every action, there is an equal, but opposite, reaction’.

Okay, so the wings are the key to making something fly—but how do they work? Most airplane wings have a curved upper surface and a flatter lower surface, making across-sectional shape called an airfoil(or aerofoil, if you're British): Photo: An airfoil wing typically has a curved upper surface and a flat lower surface. This isthe wing on NASA's sol...
If you've ever stood near a helicopter, you'll know exactly how it stays in the sky: it creates a huge "downwash" (downward moving draft) of air that balances its weight. Helicopter rotors are very similar to airplane airfoils, but spin around in a circle instead of moving forward in a straight line, like the ones on a plane. Even so, airplanes cre...
Generally, the air flowing over the top and bottom of a wing follows the curve of the wing surfaces very closely—just as you might follow it if you were tracing its outline with a pen. But as the angle of attack increases, the smooth airflow behind the wing starts to break down and become more turbulent and that reduces the lift. At a certain angle...
Now a plane doesn't throw air down behind it in a completely clean way. (You could imagine, for example, someone pushing a big crate of air out of the back door of a military transporter so it falls straight down. But it doesn't work quite like that!) Each wing actually sends air down by making a spinning vortex(a kind of mini tornado) immediately ...
Jul 8, 2024 · When an airplane flies through the air, its shape pushes the surrounding air out of the way. As the air pushes back, drag is produced. By understanding Newton’s third law, aircraft designs can be created to reduce drag and improve overall flight performance.

Mar 25, 2024 · There are four forces that aerospace engineers consider when designing an airplane: weight, thrust, drag and lift. Engineers use these forces to help design the shape of the airplane, the size of the wings, and figure out how many passengers the airplane can carry.
Aeroplanes rely on four different scientific forces to fly - thrust, drag, weight and lift - all of which act against each other. When they are all balanced, a plane will fly in a nice,...

May 13, 2021 · A pilot of a plane has special controls that can be used to fly the plane. There are levers and buttons that the pilot can push to change the yaw, pitch and roll of the plane. To roll the plane to the right or left, the ailerons are raised on one wing and lowered on the other.
