ENG-122 Exploring My Topic

http://en.wikipedia.org/wiki/Helicopter This is a very good source for research. It has information on everything from the history of the helicopter to how to fly and the purpose of the controls in the cockpit. One thing I learned from the site is the word helicopter came from the Greek words helik meaning spiral and pteron meaning wing.



http://asms.k12.ar.us/classes/humanities/amstud/97-98/helicptr/webpage.htm This site tells alot about the history of the helicopter and gives a good chronological timeline of the evolution of the helicopter. From this site I learned that some of the earliest recorded concepts of a helicopter came from china around 400 A.D.



http://helicopter-history.org/ This is another good site about the history of the helicopter and is laid out in a series of links sorted chronologically. Each link tells another fact about the development of helicopters during that time period. Paul Cornu took the first flight in a helicopter on November 13, 1907.



http://inventors.about.com/od/hstartinventions/a/helicopter.htm This site has useful information about Igor Sikorsky who was as the site states, "considered to be the "father" of helicopters not because he invented the first. He is called that because he invented the first successful helicopter, upon which further designs were based."


http://www.glue.umd.edu/~leishman/Aero/history.html#Early%20Thinking This website is a great source for the history and evolution of the helicopter. Leonardo Da Vinci contributed to the creation of the helicopter by publishing his drawings of his "aerial-screw" in 1483.
