What was the first helicopter?

Answer 1

the first helicopter/design was called the cork screw and it was made by Leonardo DA vinchi who also painted Mona lica
Paul Cornu, a French inventor, had an experimental one out in l907 (Flights) lasted for about 30 seconds or so but so did early Wright hops(the first one was either l2 or fifteen seconds. there was also an experimental helicopter from the Danish inventor and engineer Ellehammar. Ellehammer also made more conventional aircraft and the company he founded still makes, of all things, fire extinguishers! a practical application. There is some evidence of toy helicopters in l9th century Paris allegedly found by some missionary priest type wandering in either the Paris equivalent of Chinatown or one of the oriental colonies. These were vertical things with a torque tube and counter-rotating props, one wound the thing up and pulled the pin when ready to launch, known as the De Launoy top, these were a popular Chinatown toy in the US and may have been adapted to launch parachute flares, etc , you known the Oriental thing about fireworks! All of this is long before Sikorsky, who did come out with the first sustainable-flight copter around l94l and the earliest service models were in use by both Army and Navy ( the air force then being part of the Army ) as the song reveals.) in l945-Known as the R-4. yhe designation R-4 probably referred to Rotary Wing ( the rotors) Sikorsky disliked the popular ( still seen in some newspaper or magazine captions)- term ( Wingless Wonders) for helicopters, and the word itself means rotary wing. Helix- plus Copter, derived from Pteron- like in Chiroptera ( Finger-wing) and Pterodactyl- Hand wing, that"s right Batman!
