If you’re going to fly, you need to understand aerodynamics. Scientists began learning about these forces and how they work centuries ago. Bernoulli’s Theory and Newton’s laws
of motion helped build the foundation for aerodynamics. Since then, we’ve continued learning how these forces positively and negatively impact flight.Heavier-than-air aircraft must overcome gravity and drag.These are negative influences because they hinder an aircraft in flight. Gravity pulls the plane back towards the ground. And drag makes it harder for the plane to move forward.Scientists have learned how to combat these two forces by counteracting them. Thrust and lift are the two components that offset gravity and drag. Lift keeps the aircraft up and thrust keeps the aircraft moving forward. All aircraft are designed to utilize natural forces to their advantage. They also have special features that help create thrust and lift. One of these features are the specially designed airfoils. Airfoils are designed to take advantage of pressure differences to create more thrust. But they can also be designed to reduce drag. Also affecting lift is the wings’ angle- of-attack.The larger the angle is, the more the lift increases. This is just a brief overview of aerodynamics and how they impact flight.
