History

Aircraft engines mono, bi - turbo engines and propellers The Cessna 172, a single plane. A Fokker 70 of KLM in operation aterrisagem. Note the rear of the turbine, which reverses the direction of propulsion. Thus, the turbine pushes the plane back, with the aim of thrpugh the. Os aircraft mono motores, double motores and turbo-propellers are using an engine that is turning the propeller, creating the buoyancy needed to move the aircraft forward. In particular, turbo-propellers are the engines reaction (jet) to drive a helix .Sao relatively quiet, but have speed, load capacity and lower power than a similar jet. But are much cheaper and economical than the jet aircraft, making them the best option for people wishing to own a plane or to own small companies passenger and / or office. The jet aircraft Jet aircraft to make use of turbines for the creation of the force required for the handling of the aircraft forward. Jet aircraft to have much more strength and create a momentum much larger than aircraft that make use of turbo-propellers. As a result, can carry much more weight and have more speed than turbo-propellers. One however is the large amount of sound created by the turbine that makes jet aircraft to a source of noise pollution. Great wide bodies (“many bodies") as the Airbus A340 and Boeing 777 can carry hundreds of passengers and several tones of cargo and can pecorrer a distance of up to 16 thousand kilometers - slightly more than one quarter of the circumference land. Planes have a jet of high-speed cruise (700 to 900 km / h) and speeds of takeoff and landing (150 to 250 km / h). In a transaction aterrisagem, due to high speed, the plane to jet makes wide use of flaps to allow a rapprochement with lower speed (because they increase the surface of the wings and thus support), and the reverse (the turbine generates a stream air forward, not backward) in order to reduce the speed of the aircraft after touching the ground. They have a device called the turbine reverse. Or reverse the aid in the braking and landing (if any), the procedure of abortion takeoff (RTO). Aircraft supersonics Two F-22 of Lockheed Martin, on. Planes supersonic, as the Concorde and military fighters, make use of special turbines, which generate power necessary for a flight faster than the speed of sound. Furthermore, the design of the plane supersonic has certain differences with the design of subsonic aircraft, all in order to overcome the easiest way possible friction on the apparatus with air. In fighters, the area of the wings are reduced, intended to lower friction with the air (which can reach speeds extreme), requiring a very high speed to compensate for this feature. The speed of the takeoff of certain fighters get to 300km / h, others need more speed. Hence, vai will never hear that the game made a forced landing because in the absence of these high-speed aircraft planam not, fall quickly, as a Jaca. On aircraft carriers, use is a kind of catapult linear, moved to the pressure of the steam engine itself from the vessel. The catapult is below the runway, showing only a hook on the floor of the track, which fits in front undercarriage of the aircraft-making and drives to achieve the speed needed for takeoff on a short runway. At first glance, the visible part of that system is similar to the trail. At the landing speed is also high. Then the hunting down a stick with a hook at the tip (located on the back of the plane), which relates to the steel cables held on the track, helping to stop quickly. The flight at supersonic speed creates more noise than the flight at subsonic speeds. This limits the supersonic flights to areas of low or no population density. When passing an area of greatest population density, the supersonic aircraft are required to fly in speed subsonic. Some aircraft are capable of flying at speeds hypersonic, generally, speeds that exceed five times the speed of sound.
