Who knows the history of aircraft technology?

At the beginning of this century, there were two brothers in America, who made great contributions to the history of aircraft development in the world. They are the Wright brothers. At that time, most people thought that it was absolutely impossible for an airplane to fly by its own power, but the Wright brothers did not believe this conclusion. From 1900 to 1902, the two brothers made more than 1000 gliding test flights, and finally in 1903, they built the first manned aircraft "Flyer" 1. Therefore, they won the honorary award of 1909 from the US Congress. In the same year, they established Wright Aircraft Company. This is a great success in the history of aircraft development. On February 7, 2003, 2003, 2003, 2003, 2003, 2003, 2003, 2003, 2003, 2003. The plane took off from the ground in the early morning of February 17. On this day, the Wright brothers flew three times, the first flight was 12 seconds, the longest flight was 59 seconds, and the journey was about 260 meters. This picture is an airplane made by Wright Brothers 1903. 1905, they built the world's first practical plane, which can turn, tilt, fly in a circle and fly in a figure of eight, and sail continuously for more than half an hour. Since then, human aviation has turned a new page.

New plane

space plane

Space plane, that is, space plane, is a reusable winged aircraft, which has the functions of hypersonic transport aircraft and space transportation system. It can not only take off from the airport runway, but also cross the atmosphere into space at hypersonic speed, re-enter the atmosphere after completing the space mission and land horizontally at the airport. After simple maintenance, it can return to the blue sky in a short time and can be reused for dozens to hundreds of times (Figure 6-7).

Space plane has advantages that ordinary plane and spacecraft don't have: First, compared with ordinary transport plane, it can maneuver at a higher speed in the upper atmosphere or adjacent space, which greatly shortens the long-distance transportation time. For example, the German "Sangl" space plane takes only 3 hours from Frankfurt to Tokyo via Los Angeles, 15 minutes, the American "New Oriental Express" takes only 2 hours from Washington to Beijing, and it takes only 1 hour to fly from Europe to Australia. Secondly, compared with the previous single-use spacecraft and space shuttles that have been partially reused many times, the space shuttle has significantly improved in terms of reusability, airport-level take-off and landing capability, flexibility, maintainability, go-around interval and launch operation cost. Therefore, the space plane has a very broad development prospect. It can not only carry out global hypersonic transportation, but also perform various space missions like the space shuttle.

2 1 century, the space plane will usher in a new era of world aviation and space transportation and become the pride of soaring in the atmosphere and space.
