A helicopter (British:) It is kind of the plane which it occurs, and fly lift in a rotor blade called a main rotor in the body upper part by the power of the engine, and, Helicopter, Chopper) is classified in a rotor blade airplane (the spoken language). Because I am perpendicular, and a flight is possible in a horizontal direction, and even a comparatively small place can take off and land, it is used by the wide use of each kind by which is in condition to be fastened in the air and a state. I am called "copter" or in the Japanese, and the name of the helicopter comes from a spiral (helico-) and a wing (pteron) of the Greek. As for the helicopter, the exercise that is very complicated by coordinating the degree of leaning of the surface of revolution with the attack angle (an angle of pitch) of the rotor is possible. For example, other than a vertical climb and a perpendicular descent, an aerial stop I can go ahead to just beside and the back while keeping the direction of the body. In addition, there is the body which the stunt flying such as somersaults can play by the form of the later rotor head. The characteristic of such a helicopter is suitable for activity by a small place and the complicated topography, and it is used for the staff and the various transportation of the freight. The posture control that the radio control toy is complicated by the miniaturization of the electronic gyro, a high-related Buddhist clergyman becomes easy, and the popularity as the hobby is high by can transfer you in the small space. In addition, the automatic robot copter is put to practical use by observation or the pesticide scatter use. However, generally speed is slow, and the mileage has a short flying range badly when I compare it with the fixed plane (fixed-wing aircraft, an airplane) of the wing. In addition, the noise of the helicopter becomes the social problem in the North America. A trial to improve this point is tilting rotor and airplane. When it "is one of the rotating-wing aircraft getting one important lift from the above-mentioned rotor blade", according to the airworthiness examination point Part 1 "definition", the helicopter is defined. The study of the helicopter begins to a Chinese bamboo dragonfly before A.D. distantly; and in the 15th century sketching (the right figure.) of Leonardo da Vinci Besides, pass, and) that a mark based on this sketching was ever drawn on the vertical tail of the All Nippon Airways opportunity, it was pushed forward George Kay Lee in - the 19th century, a model of with the prototype production that it loaded a steam engine by some experimentalists onto in the 18th century, but it is that it is it in the 20th century that I really pick up a pilot and use the rotor, and left the ground. Thomas Edison studied the helicopter which used reaction of the combustion, but an explosion accident occurs and the happy injured person did not appear, but breaks off a study. Fixed-wing aircraft appeared, and an autogyro appeared in the interval before a helicopter being put to practical use, and knowledge of aerodynamics about the behavior of the rotor blade and the mechanical engineering was provided. French Morris Leger, Louis Breguet, pole occurred successively in 1907 and succeeded in some It is really Focke-Wulf Fw61 developed in Berlin in 1937 by Heinrich that the helicopter which I can fly properly flew first. Anton contributes to the development of the helicopter, too. which took refuge from Russia in U.S.A. let you fly VS-300 which became basic of the anti-torque tail rotor form today that an alone single rotor, the tail rotor of the pioneer of the helicopter were belonging to it for the first time in 1939. It is said that the development type of this was used in the United States Armed Forces in last years of World War II. There is a limit in that the output per the weight is small to get vertical climb / perpendicular landing / air standstill by rotor blade airplane and must really wait for adoption of the gas turbine engine which you are lightweight, and is the high output. Inventor of the airplane assumes that the helicopter is not practical in letters of 1936. In the military purposes, it is used by a guerilla war vs. a thing (existing Malaysia) of British territory Malaysia and Korean War, but Vietnam War is the first time for full-scale use. On December 11, 1951, Charles put 502 Boeing turboshaft engines on K-225. I largely improved in comparison with conventional For 1951 years, K-225 of became the world's first gas turbine engine-type helicopter. This body is stored now in Smithsonian Museum. Two years later, naval HTK-1 of the improvement type became the first twin-engine plane turbine helicopter which I flew on March 26, 1954. However, I became the first mass-produced airplanes which SE.3130 of put a turbine engine on.
