What is a profile?
Airfoil is a specific shape, especially a shape used in aircraft wings that help generate an elevator. In addition to the wings of aircraft, which are the most famous profiles, fans, propellers and some stabilizers are also in the shape of a profile profile. In nature, the profile profile is a very common shape, which is found in plants and for creatures that fly through air or swim water. The shape of the air is such that the wind can pass above and below. The shape of the upper part is designed so that, as air passes through it, it accelerates and reduces the air pressure in this area according to Bernoulli's principle. The air under the profile is not affected, so its speed is the same as it was if he first contacted the profile.
Higher pressure air tends to move towards air with lower pressure, and this pressure difference causes the force to develop under the profile profile and create lifting. The air hinge moves - or the faster the aircraft moves through the air - the greater the difference in air pressure and therefore the sentences are sentencesThe pressure of the pressure exerted. At a certain speed, enough force develops to overcome the object - such as the plane - to overcome the gravitational force and raise the ground.
profile profile can also be used to generate stroke in the direction of down and change its shape. In this case, rather than lifting that it helps the object to overcome the gravitational force, increases the power down to compensate for other ascending forces. A good example can be seen on the wings or "spoilers" found on some cars, which helps to increase the traction of the car at high speeds, so that the car remains well seated on the ground.
Airfoil can come in many different shapes, depending on the purpose for which it is intended. Profile design for specific IS tasks One of the main focus of aerodynamics and new and improved profile designs of profile continues to be created. Some profile profile shapes such as those that are designed for aircraft passengers below the speedThe sound of sound is rounded at one end of the curvature down to the point. Others, such as those designed for supersonic aircraft, have a much sharper shape.
Some profile shapes may be selected to reduce the campaign and allow higher overall speeds, the pulling has increased to slow down the vehicle or respond to different types of streams. Some profile profile designs are symmetrical, with a round curve on both sides to allow the aircraft to function as well as it flies straight or overrun flying.
