What technology makes the airplane fly?

Answer 1

A modern commercial airplane uses Turbofan Engines, which uses fans and compressors to suck in massive amouts of air. This air is then distributed into a bypass chamber and a core. In the core the air travels through more compressors, squeezing the air. Then the air is mixed with fuel and ignited. This fast and hot air is then pushed through spinning turbines, then mixed with the cool air from the bypass chamber and released through the nozzle at the end of the engine as thrust. This thrust creates a forward push. An airplane flies because its wings are shaped like aerofoils. Aerofoils are shaped like teardrops that curve downward, where the air that travels on top is faster and has lower pressure and the air that travels under is slower and has higher pressure. This ratio of pressure sucks the wing up into the air and sustains its flight. The plane must be moving forward to keep air moving around the wings, so these Turbofan Engines are used to pull the aircraft forward. To steer the plane, special flaps are used. There are many different kinds, including Ailerons, Elevators, Spoilers, the Rudder, and Flaps. Ailerons control the plane when it dips to either side, elevators control the plane when it points upward or downward, spoilers act as air brakes and slow the plane, the rudder turns the plane, and the flaps slow down the plane a lot for landings. These different flaps do what they do because they slow or stop the airflow around portions of the wings.
