This article is published on the US Centennial of Flight Commission, a valuable education and research website dedicated to show original and useful content for researchers about aeronautics. It was written by Judy Rumerman, an accomplished writer and author for many books about aeronautics. She has lots of experience with writing about the history of NASA and flying just in general. In this report, Judy Ruderman goes through the history of the helicopter and pays close attention to Leonardo Da Vinci’s Aerial Screw. She created this article to educate the reader so they can have a better understanding on the history …show more content…
The thoughts and ideas were endless if humans could achieve such a feat. Da Vinci aerial screw was the product of his dreams, but it never came true in his days. But for other dreamers, it did. Leonardo sparked their ideas. They saw that he just didn’t have enough power, but now—about 250 years later—they had the power. Vicomte Gustave Ponton d 'Amecourt attempted to make a steam powered helicopter prototype. To d’Amercout’s surprise, the prototype weight to lift ratio was off. Many thought they could do it and tried taking it from different angles, they tried to create Da Vinci’s theory of lift in many different ways. The result of this are helicopters powered by giant rubber bands, springs, gunpowder, even guncotton engines. At the end of the 19th century, there still was no helicopter, there were numerous reasons, but there was one recurring problem and it was that there wasn’t enough power. They were dealing with the same problem Da Vinci faced with his aerial screw. In the early 20th century, after centuries of human endeavor, the first helicopter was flown. It was until World War II, when the first practical helicopter was made. The reason the helicopter suddenly popped up in the 20th century was do to the combustion engine. They finally had a engine powerful enough. Inspiration from the fundamentals Leonardo Da Vinci’s created off aerial screw. The idea based on creating enough force to create lift. When it is looked upon who the is the founding fathers of vertical flight, it all goes back to Da Vinci’s aerial screw. Leonardo Da Vinci sparked the flame to the inventors fire by showing that flying a helicopter could be done. Human advancement needs to take place, and that 's what so many inventors worked towards. Trying to find that perfect energy source for the power of the helicopter and the correct
