The angle of attack refers to the slight angle of an airplane wing in relation to oncoming air, which allows the wing to “catch” the air as it moves forward. The difference of air pressure above and beneath the wing.There are two different elements that contribute to airplane wings’ ability to create lift: Simply put, airplane wings are designed to create a lift force that’s greater than the weight of the plane. Instead, the tilt and area of a plane’s wings manipulate the air particles around the plane, creating a strong enough lift that the force of gravity is overcome by the force of the air beneath the wings. Planes do not actually defy gravity, though. The harder part is conceptualizing how a plane that weighs tens of thousands of pounds can seem to defy gravity. It’s easy to visualize how thrust might be generated with an engine or a propeller after all, most people are familiar with how vehicles move on the ground. Preparing for Takeoffįor a plane to take off, enough thrust must be generated to get the plane moving in a forward direction, and enough lift must be created to get the plane off the ground. Increased friction and changes in air pressure contribute to drag.įor a basic description of the four forces of flight, look at this diagram on the Smithsonian National Air and Space Museum’s website. Drag – The force that slows the forward thrust of a plane.As energy is released backward, the plane is moved forward according to Newton’s third law of motion (for every action, there is an equal and opposite reaction). Thrust – The force that pushes a plane forward, created by a propeller or jet engine.Lift allows the plane to rise into the air and maintain flight without falling to the ground. Lift – The upward force acting on a plane.The earth’s gravitational pull keeps a plane grounded until the plane is acted upon by the opposing force, lift. Weight – The downward force acting on a plane.To understand how a plane works, you must first understand the four forces acting upon it at all times:
