• Air in Motion | How Things Fly

Flight Begins with Air in Motion. As an airplane moves through the air, its wings cause changes in the speed and pressure of the air moving past them. These changes result in the upward force called lift. To understand lift, you first have to understand how air (a gas) behaves under certain conditions. Bernoulli Principle

• Aerodynamic Lift and Drag and the Theory of Flight

Aerodynamic Lift and Drag and the Theory of Flight . The wings of birds were the original inspiration for the design of aerofoils however it was not until 1799 that engineer George Cayley carried out the first methodical study of the performance of aerofoils. His publication "On Aerial Navigation" in 1810, marked the beginning of the science of Aerodynamics.

• Introduction to Flight - Bernoulli's Principle, Aerofoil ...

Bernoulli's principle: Bernoulli's principle helps explain that an aircraft can achieve lift because of the shape of its wings. They are shaped so that that air flows faster over the top of the wing and slower underneath. Fast moving air equals low air pressure while slow moving air equals high air pressure.

• Wings and lift — Science Learning Hub

The amount of lift depends on the speed of the air around the wing and the density of the air. To produce more lift, the object must speed up and/or increase the angle of attack of the wing (by pushing the aircraft's tail downwards). Speeding up means the wings force more air downwards so lift is …

• Principles of Flight: Bernoulli's Principle

low pressure, the air below the wing pushes upward toward the air above the wing. The wing, in the middle, is then "lifted" by the force of the air perpendicular to the wing. The faster an airplane moves, the more lift there is. When the force of lift is greater than the force of gravity, the airplane is able to fly, and because of thrust ...

and faster than the air traveling below the wing. Thus, the faster moving air above the wing exerts less pressure than the slower moving air below the wing. According to the Bernoulli Principle, this pressure differential pushes the airplane upward, giving it lift. The Coanda Effect provides another important . explanation for lift. While the ...

• Principles of Flying

Lift: is produced by a lower pressure created on the upper surface of an airplane's wings compared to the pressure on the wing's lower surfaces,causing the wing to be LIFTED upward. The special shape of the airplane wing (airfoil) is designed so that air flowing over it will have to travel a greater distance and faster resulting in a lower ...

• How Do Airplanes Fly: Weight and Lift - How Airplanes Work ...

As air speeds up, its pressure drops. So the faster-moving air moving over the wing exerts less pressure on it than the slower air moving underneath the wing. The result is an upward push of lift. In the field of fluid dynamics, this is known as Bernoulli's principle.

• Plane Wing Simulator - Science World

This principle is partially responsible for the ability of an airplane to lift off the ground. When an airplane moves through the air, the wings push against the air, so that the airflow is slower under the wing than above it. As a result, Bernoulli's principle tells us that there will be more pressure on the bottom of the wing than on the top.

• Theory of Flight

When the air cools, the particles fall back to Earth. Heavier-than-air flight is made possible by a careful balance of four physical forces: lift, drag, weight, and thrust. For flight, an aircraft's lift must balance its weight, and its thrust must exceed its drag. A plane uses its wings for lift and its engines for thrust.

• Factors Affecting Lift | How Things Fly

The wings are shaped and tilted so that the air moving over the top has less room than the air moving below the wings. The air moving over the top must speed up more than the air below the wing, because of conservation of mass. As it moves faster, the air on top of the wing also loses pressure and push.
