Igor Sikorsky designed the first truly succesful helicopter with the VS-300. The VS-300 went through its flight testst between 1939-1941. The VS-300 became the base model for many helicopters that came after it.
Around 1940
The first Bell 553 helicopter was officially built in the year 1903 which was specifically researched and made by Bell at high air speeds which was his first experiment.

Igor Sikorsky, a Russian- American immigrant invented the first successful helicopter, model number VS-300. There is no specific invention "date" but it was first test flown in September 14, 1939 and had to be tethered by cables because of its instability.

The very first piloted helicopter was invented by Paul Cornu in 1907, however, this design was not successful. French inventor, Etienne Oehmichen built and flew a helicopter one kilometer in 1924. Another early helicopter that flew for a decent distance was the German Focke-Wulf Fw 61, invented by an unknown inventor. 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.
That was around 1941
1901
