    “Paul Corunade” is the first person who designed the helicopter in 1907, but it didn’t work well. “Igor Sikorsky” is called the father of helicopter because he made the helicopter in 1940 with proper design that worked well. The designing of the helicopters was so perfect, almost of the today’s helicopter are of the same design.
