Balloon Festival in Italy
Several dozen multi-colored balloons adorned the sky above the picturesque Italian valley in the Umbria region at the end of July. All of them are participants of the International Balloon Festival.
A balloon is an aircraft lighter than air, whose principle of action is based on Archimedes' law. To create lift, encapsulated gas (often just heated air) is used with a density less than that of the surrounding air.
If you attach an engine to a balloon, it will become an airship.
Balloons for the first time allowed man to rise into the air, and later to reach the stratosphere. Balloons that rise to an altitude of more than 11 km are called stratostatos.
During World War II, balloons were widely used to protect cities, industrial areas, naval bases and other objects from air attack. The action of the barrage balloons was designed to damage the aircraft in a collision with cables, sheaths or explosive charges suspended from cables.
During the Cold War, automatic drifting balloons (ADA) were widely used by Western countries to conduct reconnaissance over the territory of the USSR. The vehicles were hardly noticeable, autonomous, relatively cheap, and flew at large, inaccessible at that time, heights over 20 kilometers. This made the detection of ADA difficult, and the destruction inadequately expensive.
May 27, 1931 Auguste Piccard and Paul Kipfer were the first to reach the stratosphere in a balloon.
On August 31, 1933, Alexander Dahl, while aboard an open balloon, took the first picture, which shows the roundness of the Earth.
The current altitude record was set on October 24, 2014 by Alan Eustace, rising to a height of about 41,421 meters in a spacesuit attached to a balloon over the US state of New Mexico.
The altitude record for a multi-seat manned balloon was set on May 4, 1961: having started from the deck of the USS Antietam in the Gulf of Mexico, the balloon rose to an altitude of 34.7 km.
On March 1, 1999, the first non-stop round-the-world flight was made in a balloon - 40,814 kilometers of flight in 19 days, 21 hours and 55 minutes (average speed - 85.4 km / h).
The altitude record for the unmanned ball is 53.0 km.The ball was launched on May 25, 2002 from Iwate Prefecture, Japan. This is the highest altitude ever achieved by an aeronautic. Only rockets, rocket planes and artillery shells can fly higher.
12. Well, we are at the festival of balloons in Italy.
“This is a great way to see the world. It is not like what you see from an airplane or a helicopter. Here is a 360 degree view, and you don’t know where you will fly to, where you will land.
