Whenever I see an explanation about how airplanes can fly, I see that the shape of the wing is different on the top side to create a dragging force that pushes the airplane up. The top is curved and the bottom is flat. If a airplane turn upside down, should it fall faster because it’s dragging down ? I saw airplanes doing acrobatics on air , and some of them looks impossible because of this.
In: Engineering
An acrobatic airplane has a less efficient wing shape to make it useable in regular and inverted flight, and then typically makes up for it with raw power.
Or if doing a loop, use gravity to build up more speed. More speed, more airflow over the wing, more lift.
