The American company Piasecki sold its first tandem rotor helicopter the HRP-1 to the US navy in 1944. This series of helicopters would lead to the famous H-21 of Vietnam war fame.
dung the ch 47 came from the pieiseki h 21 AKA the flying banana!! the h 21 was started in 52! there wasn't enough yak 24's built to even be noticed by NATO intelligence! back then the only way NATO knew to even look for new birds going into service was the mayday parade fly overs the new ones made!
@@keithmoore5306 Thank you for your reply, Keith. Please: 1 - I was referring to the twin rotor Sea Knight. 2 - My information is: Sea Knight first flight 22Apr58 and Chinook first flight 21Sep61. The Sea knight was never as famous as the Chinook or even the Sea King of course. Stay well.
@@keithmoore5306 Easily done, Keith. Different topic: ever been to the Madrid Air Museum? I went last week and found 41 types I'd never seen before, inc some I'd never heard of, and I know a few! There are 2 or 3 youtube videos on the place. Motorways a nightmare, by the way.
This distresses me at the moment, when Putin is threatening the world with total destruction. But the development was based on the flying banana, which preceded it, and was upgraded to turbo shaft engines as well.
The H-21 was being designed in 1944, proposed in 49’ and entered in 1952. 2 years before the Yak-24. The yak-24 is a failure and has no real connection to the American CH-46 or CH-47.

Wasn't the Sea Knight between the Piasecki and the Chinook? That's the one in "You Only Live Twice" which dumps the villains in the sea.
@@jjmcrosbie the chinook's first flight was in 57 the sea king in 59! the H19 chickasaw came between them though!

Failure in production, typical soviet quality
الفشل بيكم تسرقون اسلحه السوفيت وتقومون بصناعه مثلها
Nope. The Soviets were trying to make their own tandem rotor helicopter based on the US' successful designs. They failed.
