The history of aircraft
The first attempts to build the aircraft has been made in the nineteenth century, in particular, the plane was built by Russian engineer Mozhaisk. However, none of these designs are not able to rise into the air.
The reasons for this were: too high a mass, and the inability of the then engines (steam engines) to the conditions of aviation.
The first plane, which could itself off the ground and make a horizontal flight, became the "Flyer", built by brothers Orville and Wilbur Wright in the United States. First flight in history was made on Dec. 17, 1903-year. "Flyer" stayed on the air 59 seconds and flew 260 meters. The brainchild of Wright was officially recognized by the world's first heavier-than air, which made a manned flight using the engine.
Their apparatus consisted of a biplane type "duck" - the pilot was placed on the lower wing, the rudder behind the elevator in front. Two-spar wings were covered with thin unbleached muslin. Engine "Flyer" was a four-stroke, with a starting capacity of 16 horsepower and weighed only 80 kilograms.
The device had two wooden screws. Instead, Wright used a wheeled chassis launch catapult, consisting of a pyramidal tower and wooden guide rail. The drive was carried out with the help catapult the incident bulk cargo that is associated with an aircraft cable through a system of special units.
