Many people today have flown in an airplane. This is a common communications network today. Air transport is essential for long-distance calls. Many ask the simple question “What makes an airplane fly?” The answer is often misleading and often just plain wrong. We hope to clarify here the answers to many misunderstandings. We will show that it is lifted more easily understood if one starts with Newton rather than Bernoulli. It will also show that the popular explanation that most of us were taught is misleading at best, and that the increase is on the wing diverting air down.
To fly a plane, you should always engage in a fierce battle between the opposing forces of the elevator between the weight and push against the resistance. Hold for a moment of an aircraft from right to left, and the air flow from left to right. The weight or gravity pulled down side is opposite the lift generated by the air flowing over the wing. The thrust is generated by the propeller and the air resistance opposed by the drag caused on the plane. During startup, the drive must be greater than the resistance and the buoyancy be greater than the weight, so that the aircraft can run. By the thrust of the landing must be less than the friction, and an elevator must be less than weight.
An aircraft in flight is the center of a tug of war between permanent four forces: lift, gravity, or weight, thrust and drag. Lift and drag are considered the aerodynamic forces, because, due to the movement of the aircraft in the air. The weight pulls down on the opposite lift generated by the air flowing over the wing. The thrust is generated by the propeller and against the resistance caused by air resistance on the front of the aircraft. During launch, the thrust must overcome the resistance and buoyancy, the weight must be overcome before the aircraft can take off. In level flight at constant speed, thrust exactly equals the friction and lift exactly equals the weight or gravity. For thrust bearings must be reduced below the level of drag and lift below the level of the force of gravity or the weight.
Elevator: Elevator by a lower pressure in the upper surface of an aircraft wing with respect to the pressure on the lower surface of the wing to the wing-prepared “lift” is applied to the top. The particular shape of the wing of an aircraft (aerodynamics) is designed so that air flows over, he will drive a faster route, leading to a low pressure area (see illustration) thus lifting the wing up. Lift is the force of gravity (or weight) counter.
Many people think that this statement is incorrect because flat wings have (as on balsa wood airplanes, paper airplanes to see, etc.) also managed to create lift. Please read How planes fly: the physical description of the flight and get a better understanding of the formation of a lift. Is more advanced, however.
Stop: Shear is a force from a power source that produces a forward movement of the aircraft are. You can “draw” or “push” an airplane forward. Shear strength, resistance is overcome. Aircraft engines with conventional propellers, and get a boost.
Drag: resistance is the force which delays or slows the forward movement of an aircraft in the air, when the direction of air flow opposite to the direction of movement of the aircraft. Is the friction of the air meets and passes over and around the aircraft and its components. Surface exposed to the air precipitation, the greater friction. An aerodynamic shape of the aircraft with the air to pass through easily.
