The history of jetpacks: what were they like before and why doesn't everyone have them today?

[zakiyatasnim]

The path to personal flying vehicles is thorny and explosive. Controlling a jetpack is difficult even in games. In real life, early developments were almost not dangerous, because they remained on paper and simply did not fly. When they managed to get off the ground, problems with landing began, and fuel could run out at any moment.

The history of jetpacks began about a century ago, and kuwait number data not, as is commonly believed, with the development of Wendell Moore (1958). Soviet engineer Alexander Andreev registered a patent for the first jetpack in 1928. Andreev's development showed in detail for the first time how a person could rise into the air using jet thrust. The technology involved rapid heating and expansion of a liquefied gas, which would allow a person to stay in the air. A drawing of the device was also attached to the patent. However, understanding from it how a pilot would control the backpack is not the easiest task. Unfortunately, having received the patent, Andreev was unable to implement his idea, which was ahead of its time.



Hydrogen peroxide rocket engines became widespread during World War II. Germany actively used them in torpedoes and missiles, installed them on submarines and aircraft. For example, the Messerschmitt Me.163, which made its first combat sortie in 1944, could reach speeds of up to 960 km/h, but its fuel supply was only enough for 12 minutes. It was in this model that stabilized 80% hydrogen peroxide was used as an oxidizer, and a mixture of ~57% methanol as a fuel.
