Flight

Flight Research: Airplanes are an efficient way of traveling to far places. Airplanes are amazing if you know what and how the air keeps the plane airborne. There are three components of flight: aerodynamics, the Bernoulli principal and supersonic flight. Some other things about flight are the four forces, lift, drag, weight, and thrust. One of the basic things you need to know about airplanes is that the places where the plane can balance on one point called the center of gravity. The tail on the plane is needed to balance the pitching movement. First of all, aerodynamics plays a major role on many things, especially in airplanes. Aerodynamics is the reaction of the air on the specially shaped wing that lifts an airplane off the ground. Also, aerodynamics is the study of gases in motion. The term aerodynamics comes from the Greeks meaning air power. Isaac Newton bases aerodynamics on the physics theorem. People who experiment with aerodynamics are called aerodynamicist. Their basic tool is the wind tunnel. A professor of engineering, Osborne Reynolds, conducted many experiments with paper airplanes and regular airplanes and found out Viscosity (thickness) affects the way fluids behave. All fluids have some viscosity.
