Wings
The definition of an airplane according to Marks Standard Handbook for Mechanical Engineers, is "a mechanically driven fixed-wing aircraft, heavier than air, which is supported by the dynamic reaction of the air against the wings." For an airplane to fly, it has three basic concepts. One for the airplane to be dynamically shaped for maximum efficiency. Two for the airplane to have the power to fly, the engines. Three, for the wings are dynamically shaped in every way, so the airplane can have its maximum lift. For the wings to have its lift and for it to have its maximum efficiency there are three major concepts for the wings. The first concept of the wings is how the wings help the airplane fly. The definition of lift according to Marks Standard Handbook for Mechanical Engineers, is "the component of the resultant force exerted by a fluid on a body perpendicular to the relative motion of the fluid." The formula for lift in pounds is CLPAV2/2. Lift is made by a drop in air pressure creates lift over an airplane's wing. An airplane wing has a curved upper surface. As a plane moves forward, the pressure of that air that rushes over this curved surface falls. A high-pressure area always moves toward the low-pressure area.
The second concept consists of 2 things: the angle of attack and the stream line affect. In this report I talked about three major concepts. The first concept was lift. How if there were no lift from the wings, the airplane would not be able to fly at all. How the lift comes from the dynamic shapes of the wings. The second concept consists of angle of attack, the streamline effect, and the weight distribution. The angle of attack helps out with the lift greatly. The streamline affect told us that the top of the wing has to be longer than the bottom so the air would "stick" to the wing and give it more pressure. The third concept included the flaps and slots. Without those slots and flaps the airplane would not be able to fly so smoothly. When flying on an airplane next time, remember these three concepts and you will know why the airplane flies. Flaps are used on an airplane mainly when they are taking off or landing. They can cause the air to flow over them, therefore causing the airplane to slow down. Like the parachute effect. Flaps usually are drooping down from the trailing edge of the wing, though some planes have leading-edge flaps too. On some planes, they also can be extended back beyond the normal trailing edge of the wing and actually increase the surface area of the wing, as well as change the shape of the wing drooping down. Leading-edge slats usually extend from the front of the wing at low speeds to change the way the air flows over the wing, and that increases lift. Flaps also serve to increase drag and slow the approach of a landing of an airpla
