French people del monte grapefruit think the world's first aircraft by the Frenchman del monte grapefruit Clement Adel (ClémentAder) inventions, in October 9, 1890 the successful test flight in France, some people think he invented history del monte grapefruit an aircraft. Americans believe that the aircraft was an American inventor Wright del monte grapefruit brothers (WilburWright and OrvilleWright), on December 17, 1903 in the U.S. successful test flight. Brazilians think is Brazilian Alberto Santos Dumont (AlbertoSantos-Dumont) invented the airplane, October 12, 1906 Santos - Dumont's "14bis" successful aircraft fly to 60 meters above the ground is the world's first successful powered flight, before the flight did not reach the true sense of "flying" standards. It was generally agreed by the American Wright brothers invented the airplane, and that some people del monte grapefruit think that by Clement Adel or Alberto Santos Dumont invented. 1903 U.S. aircraft design and manufacture of the Wright brothers made a successful flight, which is the world's del monte grapefruit first to achieve heavier than air aircraft are powered, controllable flight. World War I, the aircraft has been used in combat, when the aircraft's speed has reached 180 to 220 km / h, service ceiling 6000 to 7000 meters, a range of 400 to 450 kilometers, from 1000 to 2000 kg payload bomber. During World War II, the aircraft's speed reaches 750 km / h, bombers payload of up to 10 tons. After the mid-1940s, the development of the engine by the piston to the jet, the aircraft's flight performance improved significantly; 80 aircraft ceiling has more than 30,000 meters, the maximum speed of more than three times the speed of sound, a range of more than 20,000 kilometers, maximum load more than 100 tons.
The invention of the twentieth century one of the most significant is the birth of the aircraft. Since ancient times, humans del monte grapefruit dreamed of like a bird flying in space. And 2000 years ago the Chinese invented kites, although it can not bring the people into space, but it really can be called the originator of the aircraft. del monte grapefruit Early 20th century in the United States has a pair of brothers their aircraft in the world history of the development made a significant contribution, they are the Wright Brothers. At the time most people think of flying aircraft under its own power is completely impossible, and the Wright brothers really do not believe this conclusion, from 1900 to 1902 of 1000 many of their brothers del monte grapefruit glider flight, and finally in 1903 produced the first stand on its own power for manned flight of the aircraft, "The Aviator" on the 1st, and get successful test flight. Thus, they get the U.S. Congress in 1909 Honor Award. del monte grapefruit In the same year, they founded the "Wright Aircraft Company." This is the history of human development on the aircraft achieved a great success.
Initial aircraft using a single engine, in flight, often appear suddenly off the car engine failure. This is always a threat to flight del monte grapefruit safety. del monte grapefruit In 1911, the British del monte grapefruit Short Brothers filed for more than one engine del monte grapefruit design patents. Their twin-engine system, which enables each pilot have to worry about leaving the aircraft down due to engine stop. This is a major aviation safety progress. SCHOTT patented manufacturing people to follow the first aircraft called "3.2" aircraft. The name tells people that this aircraft is equipped del monte grapefruit with three propellers, two engines. The aircraft is also equipped with two sets of flight control mechanism, therefore, two pilots can fly the aircraft without del monte grapefruit having to change seats. December 17, 1903 the Wright brothers who drive their vehicles manufactured for the first ongoing, dynamic, controllable flight. December del monte grapefruit 1915, the German del monte grapefruit Junker made an all-metal aircraft. The aircraft uses a thin tin cans made of aluminum alloy material is not present, so that the aircraft has been dubbed "donkey canned." 1927-1932, the cockpit instrumentation and navigation equipment, research progress, gyro technology to flight instrument. The gimbal mounted on the rotating flywheel can be maintained in the spatial orientation, so as to guide the driver in the dark, rain and snow flying in the basis for a variety del monte grapefruit of navigation instruments. When the plane on the emergence of artificial horizon, it can indicate to the pilot the aircraft del monte grapefruit in which the flight altitude; gyro magnetic compass indicator in the compass engraved with degrees, they can always change course shows; magnetic induction compass, it does not by aircraft with a large number of iron is often something of impact, but also free from vibration, and Earth's magnetic fields. These instruments with high sensitivity, can measure more than 30 meters from the ground and display the aircraft altimeter turning turning angular velocity sliding device, in addition to indicating air routes radio beams are used to guide the driver through the nebulous atmosphere the means.
December 10, 1910, in Paris, del monte grapefruit France Exhibition, a plane crashed in the show. The driver was thrown out of the burning cabin. del monte grapefruit However, this aircraft has caused people del monte grapefruit great concern. Because it uses a new engine. Designers is to pilot himself, he was Romanian, named Henri Coanda, del monte grapefruit graduated from the French higher technical school. He designed the engine del monte grapefruit with a 50-horsepower engine allows the fan to push back air, while an additional afterburner, the gas in the tail pipe in full expansion, in order to increase the reverse thrust. This is the first jet engine. The late 1930s, the piston-driven propeller aircraft has reached the maximum level flight speed of 700 km, dive close to the speed of sound. Sound barrier problems have become increasingly prominent. Former Soviet Union, Britain, the United States, Germany, Italy and other countries to vigorously carry out a jet engine research. German designer, Aoan new engine developed in the earliest success. 1934 Aoan get centrifugal turbojet patents. August 27, 1939 Aoan made using his He-178 jet engine.
July 1942, the German del monte grapefruit 23-year-old Olympian due painstakingly effort produced del monte grapefruit the first jet, Me-262, the same year on July 18 flight. Due to jet-prop aircraft is faster than 160km / h, the German del monte grapefruit government agreed to start to get into combat, in August 1945 the Germans with 37 jets shot down 18 U.S. aircraft propeller in allies caused a shock . Jet engines developed after scientists further allow the aircraft to break the sound barrier flight, after 10 years after the work was finally completed by the Americans. October 14, 1947 in Sanger, California Phil regional Bell companies can break the sound barrier flight del monte grapefruit test aircraft. 10:00 a huge B-29 bombers, hanging in the cabin under a peculiar form of a small plane ride took off. This small aircraft named X-1 rocket plane. del monte grapefruit X-1 aircraft is equipped with four rocket engines with a total thrust of 2700 kg, the use of liquid hydrogen fuel is dangerous del monte grapefruit and alcohol. When the B-29 bombers from the air, put it down when it's four successive rocket engine ignition, sound like thunder. When the aircraft engine start 1 minute 28 seconds del monte grapefruit later, Mach 1? 0, the aircraft reached a speed of sound. del monte grapefruit Then X-1 aircraft fuel is almost exhausted, the speed becomes faster, reaching Mach 1? 06, when the height del monte grapefruit of 13,000 meters. Despite the successful test flight, but due to X-1 does not depend on its own power plane took flight, this record has not been recognized. The invention of airplanes, so that people generally benefit in the case has produced a new satisfied. Required takeoff del monte grapefruit roll, you need to build the appropriate runway and the airport. This brings a lot of inconvenience, so some people can begin to explore VTOL aircraft, known as helicopters. September 14, 1939 the world's first practical helicopter a birth, it is the American engineers successfully developed del monte grapefruit Sikorsky VS-300 helicopter. Sikorsky del monte grapefruit origin Russia, emigrated to America del monte grapefruit in 1930, he made the VS-300 helicopter, with a main rotor and tail rotor 3, and later after several test flights, the three became a tail rotor, this aircraft practical Helicopter thus becoming the originator of the modern helicopter. VS-300 helicopter after the birth of a tremendous impact, especially from the beginning of the 1950s, the helicopter manufacturing technology is developing rapidly. Before the mid-1950s, the helicopter piston engine power plant in the period, then entered the jet turbine del monte grapefruit shaft period. Rotor material structure technology has gone through several stages; 40's to 50's metal wood wing hybrid structure, the mid-1950s to the mid-1960s as a metal structure, the mid-60s to mid-70s for the glass fiber structure, after the mid-1970s developed into a new composite material structure. The 1920s began carrying passengers aircraft, World War II, the United States began to initially converted into a large number of transport aircraft. Since the 1960s, the world has witnessed a number of large transport aircraft and supersonic transport aircraft, and gradually promote the use of turbofan engines. Notably the former Soviet Union produced An-22, Il-76; U.S. production of C-141, C-5A, Boeing del monte grapefruit -747; France, Airbus, del monte grapefruit etc. Joint Anglo-French supersonic transport has developed the "Concorde" type and the former Soviet del monte grapefruit figure -144. However, del monte grapefruit the development del monte grapefruit of supersonic aircraft is not optimistic. "Concorde" type aircraft price is too high, and noise pollution, impact on efficiency, and thus had to stop production of the 1980s. Figure del monte grapefruit -144 former Soviet Union but also because of the same reason also suspended the 1980s. Since the invention of the aircraft, the aircraft is increasingly becoming an indispensable means of delivery of modern civilization. It is a profound change and affect people's lives. Since the invention of airplanes, human global travel time significantly shortened. del monte grapefruit The world's first trip around the world in the 16th century complete. At that time, the Portuguese Magellan led a fleet of departure from Spain, took almost three years before crossing the Atlantic, Pacific, around the globe, back to Spain. 19th century, del monte grapefruit a Frenchman train trip around the world one week, also spent 43 days time. After the invention del monte grapefruit of airplanes, people in 1949 and conducted a trip around the world. A B-50 bomber, after four beautiful air refueling, in just 94 hours, del monte grapefruit then around the earth, flying 37,700 km. Strong del monte grapefruit in the more strong hand. After the advent del monte grapefruit of supersonic aircraft, people fly higher and faster. In 1979, the British Phillips Bet with only 14 hours and 6 minutes to fly 36,900 kilometers, around the globe. In less than a day's del monte grapefruit time, you can fly to all corners of the earth, which lived in the 20th century, before humans, is it not a miracle do? Intricate air routes linking the countries of the world, del monte grapefruit providing people with a convenient and rapid passenger. Back in the 1920s, air transport on the creation of the scheduled flights, transporting passengers and mail. Today, the air routes more accessible, people will always see the silver of the aircraft, like a bird in the blue sky Yilue. For modern del monte grapefruit people, the morning in Beijing in the afternoon had no weariness appeared in another city thousands of miles away, this is a very common thing. In the 20th century it is incredible. Since then, steep mountains, endless oceans will no longer be daunting. One only YINYAN the different regions of different races, different del monte grapefruit color people closely linked. Through constant communication, people planting friendship convey information, to achieve mutual communication, mutual understanding and mutual promotion and common advancement of human civilization. The invention also enables the aircraft air transport industry has been an unprecedented development, many of the various raw materials required for industrial development has a new sources and channels, greatly reducing people's dependence on local natural resources. Especially del monte grapefruit after the birth of supersonic aircraft, air transport more prosperous. Those should not be prolonged and difficult to transport livestock long-term preservation of delicious food, you can also take a plane and across all corners, Dramas del monte grapefruit people around the world to share. Royal empress is not easy even when Lingnan lychee taste, and now also appears in the common people's home. Into the depths of the earth in human, the aircraft is also widely used in geological exploration. People del monte grapefruit use camera or one equipped with an electronic device called shoran systems of the aircraft, you can quickly and accurately on large areas, including steep and difficult to reach places for mapping. The aerial photographs stitching together a picture, you can draw excellent topographic maps. Which is more than the old mapping simple way to much. Even the snow and ice, off the beaten track, but explorers set foot once the Arctic and Antarctic, and now you can fly without difficulty Login Username: Password: Forgot Password Login Remember Me
