aircraft
aircraft.To meet the needs of displaced people, since ancient times a lot of effort to create a tool that can make it start that. from many experiments that are not often experienced many failures.
from cars, trains, ships and air transportation is an airplane.
Aircraft that is heavier than air was first flown by the Wright brothers (Orville Wright and Wilbur Wright) by using their own aircraft design called the Flyer, which was launched in 1903 in the United States. In addition to the Wright brothers, inventors listed several other aircraft that found among other aircraft Samuel F Cody who perform actions in the field Fanborough, England in 1910. While for aircraft lighter than air have to fly much earlier. First flight by using hot air balloons found in a French named Joseph Montgolfier and Etiene Montgolfier occurred in 1782, then completed a German named Ferdinand von Zeppelin, by modifying the cigar-shaped balloon that is used to carry passengers and goods in 1900. In the next year Zeppelin air freight to ship disaster Zeppelin on the trans-Atlantic trip in New Jersey in 1936 which marked the end of Zeppelin era, although still in use before World War II. After the Wright era, the aircraft experienced a lot of good modification of design, shape and aircraft engines to meet air transportation needs.
Aircraft that is lighter than air aerostat is called, who fall into this category is balloons and air ships. Aerostat using buoyant force to fly in the air like a ship that used to float on the water. These aircraft generally use a gas such as helium, hydrogen, or hot air to generate the buoyancy. Differences in hot-air balloon with the air ship is a hot-air balloon over the wind, while the aircraft has a propulsion system to push forward and control systems.
Fixed wing aircraft generally use a form of internal combustion engine piston engine (with a propeller) or a turbine engine (jet or turboprop), to produce the impetus that drives the aircraft, and air movement in the wings to produce thrust upward, which makes this aircraft can fly.
As an exception, there is also a fixed wing aircraft that do not use machines, such as gliders, which uses only gravity and the flow of hot air.
