Charter Jets – Aerodynamics

Many people believe that a pilot must work constantly to keep the charter jet in the air. With the study of aerodynamics we can understand how charter jet, can and do fly. Aerodynamics is the way air moves against objects or of objects moving through the air. The science of aerodynamics is used in designing airplanes, ships, trains, automobiles and other objects to help them move smoothly through the air.

Wikipedia: Aerodynamics is a branch of dynamics concerned with studying the motion of air, particularly when it interacts with a moving object. Aerodynamics is a study field of fluid dynamics and gas dynamics, with much theory shared between them.

Aircraft’s are actually designed to be stable. The pilot merely needs to use a small amount of pressure on the controls from time to time to make the charter jet to turn or go up and down. Many people also believe that if the airplane engine stops running while it is in the air, that it will fall straight to the ground. This is not really the case either. When the airplane’s engine stopped in flight the airplane will glide to the ground like a sled coasting down a hill and can usually be landed safely on any level field.

There are four forces that act on an airplane in flight. These forces are drag, lift, thrust and gravity. Lift is the force which counteracts gravity. It is caused by the motion of air over and under the airplanes wings when the plane is moving. Wings or airfoils are designed to produce lift. Lift is produced in two ways. One way is by the direct pressure of air against a tilted wing. Air in motion exerts a pressure against any object that it strikes.

Gravity is the force of the earth’s downward pull. Gravity must be overcome for a charter jet to leave the ground and to stay in the air. The center of gravity is the point within the charter jet on which the airplane will balance. If the center of gravity is in front of the wings the plane will be nose-heavy. If the center of gravity is behind the wings the plane is tail-heavy.

Drag is the force which resists the forward motion of an object through the air. Lastly is the thrust is the force which carries the charter jet forward through the air.
