In what year did the Wright brothers make their first successful powered flight? How did people react?
Airplanes fly by using aerodynamics to generate lift, thrust and drag. The air inside an airplane cabin is pressurized to keep passengers comfortable. Aircraft engines use fuel to generate energy to power the plane.
Exploring the Science of Airplanes
What do you think is the most interesting thing about airplanes?
- The way they take off and land
- The science behind how they fly
- The way they look in the sky
- The engineering involved in designing them
The aerofoil shape of an airplane wing is designed to create an area of low air pressure above the wing, which lifts the plane into the air. The force of lift is equal to the weight of the airplane, allowing the plane to stay in the air. The air flowing over the wings of an airplane creates a pressure differential that produces a low pressure area above the wing and a higher pressure area below the wing.
