Năm 1863, người Pháp viết Poton D 'Amecourt là người đầu tiên tạo ra từ' 'trực thăng' 'từ hai từ' helico '' cho xoắn ốc và '' pter '' cho đôi cánh. Trực thăng đầu tiên được phát minh bởi Paul Cornu năm 1907, nhưng nó đã không thành công. Nhà phát minh Pháp, Etienne Oehmichen đã xây dựng và bay trực thăng một năm vào năm 1924.
Tuy nhiên, Igor Sikorsky được coi là cha của máy bay trực thăng không phải vì ông đã phát minh ra chiếc đầu tiên. Ông được gọi là vì ông đã sáng tạo ra chiếc máy bay trực thăng thành công đầu tiên, dựa trên những thiết kế khác. Một trong những nhà thiết kế vĩ đại nhất của ngành hàng không, Igor Sikorsky sinh ra tại Nga bắt đầu làm việc trực thăng vào năm 1910. Đến năm 1940, VS-300 của Igor Sikorsky đã trở thành mô hình cho tất cả các trực thăng hiện đại ngày nay. Ông cũng thiết kế và xây dựng trực thăng quân sự đầu tiên.
Trực thăng của Igor Sikorsky có quyền kiểm soát bay an toàn về phía trước và ngược lại, lên xuống, và đi ngang. Năm 1958, công ty của Igor Sikorsky đã đưa chiếc trực thăng đầu tiên trên thế giới có thể hạ cánh xuống bờ biển. Nó cũng có thể nổi trên mặt nước.
In 1863, the French write Poton D' Amecourt was the first person to create the word ''helicopter'' from the two words ''helico'' for spiral and ''pter'' for wings. The very first helicopter was invented by Paul Cornu in 1907, but it was not successful. French inventor, Etienne Oehmichen built and flew a helicopter one kilometer in 1924.
However, Igor Sikorsky is 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. One of aviation's greatest designers, Russian born Igor Sikorsky began work on helicopters as early as 1910. By 1940, Igor Sikorsky's successful VS-300 had become the model for all modern helicopters of today. He also designed and built the first military helicopter.
Igor Sikorsky's helicopters had the control to fly safely forwards and backwards, up and down, and sideways. In 1958, Igor Sikorsky's company made the world's first helicopter that could land and take off from water. It could also float on the water
