The birth and evolution of hot air balloon

If the fibers of textiles are woven tightly enough and coated with the original paint made of gum or other substances seamlessly, human beings can invent hot air balloons and travel in the air by hot air balloons at some time 5000 years ago. However, the hot air balloon was not successfully developed until 1783-this is simply unreasonable.

The Montgolfi brothers are the inventors of hot air balloons, and Joseph Montgolfi brothers are paper workers in Annodi near Lyon, France. When they saw pieces of paper dancing on the bonfire, they all had the idea of making flying objects with hot air. From paper bags to cloth bags, until the giant hot air balloon public performance 1783 on June 5, it was successful step by step. The hot air balloon controls the flying height of the balloon by supplementing or exhausting hot air from the bottom, and is propelled by a human-driven propeller. Although it was impossible to travel in windy days, it was indeed a quite satisfactory air traffic at that time.

After the balloon was successfully launched, people began to try to install power for the balloon, because people, as an animal, have too little power as an "engine" for propulsion. It is also based on this idea that the airship that ruled the air for a period of time was born.

Many airship models with different shapes want to be born one after another, but they have not been realized for one reason or another. The earliest airship was first made by French engineer Gifard. Although it can rise into the air, the original steam engine is still quite imperfect and its dynamic performance is quite disappointing.

It was not until 1884 that two military engineers, Leonard and krebs, used the motor as the power to design the world's earliest practical flexible airship-France. Since then, the airship has stepped onto the historical stage as the most successful manned aircraft in history. A blimp looks no different from a hot air balloon, except that it is equipped with a more advanced power device at that time.

In the late 1980s, people began to use gasoline engines to power experimental airships. 1900, the first rigid airship "LZ- 1" was built in Zeppelin, Germany. The airship is not only brand-new, but also powered by a gasoline engine, and its power performance has been improved as never before. 19 10, led zeppelin officially became the main means of transportation in the air because of its unparalleled safety, reliability and weight. In the following decades, more than 800 "flights" were flown one after another, carrying more than 7000 passengers/kloc-0, and the voyage reached 185000 km. At the same time, the airship was also used for military purposes and was the earliest air force. Zeppelin is also known as the "father of the airship".

While the airship gradually ruled the vast sky, the birth of the plane began to challenge this kind of air hegemony. In 1930s, while the airplane was gradually perfected and put into practical use, the airship suffered several disasters, which made it replace the airplane in less than a century.

Nowadays, airships are rare, and there is no practical manned airship. It is the originator of the airship, but it has become a kind of sports and leisure-hot air balloon sports, which is favored by many fans in the world.
