HELICOPTERS (helik-o-pter)

HELICOPTERS (helik-o-pter): "



“If Icarus hadn’t flown so close to the sun we would all have a second home in Mars by now””


The story of Icarus is a symbol of the human desire to fly,to explore,to escape…and when we think of flying,the airplane comes first to our mind,but helicopter flight was the first kind of flight captured by human imagination.


In the suburbs of a chinese city about 500 years ago kids playing with hand-spun bamboo made toys discovered what may be the first rotary wing in history.Eventhough we have to wait for Leonardo Da Vinci to get the first schemes of “rotary aircrafts”


In the midst of the pioneers of aviation we can’t not mention Sir George Cayley,Alphonse Penaud who developed the coaxial rotor model and Gustave de Ponton d’Amécourt who coined the word “helicopter”,deriving for ancient greek


“”helik”= “spiral” ” and “pter” = “wing”


But we have to wait for two brothers called Jacques and Louis Berget,to see a rotary wing aircraft which they called Gyroplane No1 lift vertically from the Ground


A helicopter is a rotary wing aircraft.
