Helicopters: Thank you, Mr. Sikorsky!

The whole range of Soviet "monster" helicopters Another Goliath is the MI-6, made by the Soviet Mikhail Mil design bureau. Again created in the 50s, the MI-6 was a true monster. While not as oddly stylish as the Chinook, this powerhouse could lift 26,000 pounds of cargo (12 tons), being an incredibly versatile heavy hauler. Almost all of these types of machines were very popular with the Soviets, spawning a whole range of monster helicopters, some of whose descendants are still in use today.

The Fairey Rotodyne, 1959, advertised as the "first vertical take-off airliner in the world" (project scrapped in 1962) and the first helicopter airline in the world: New York Airways, 1953
Mil V-12


Sure it has rotors -- it wouldn't be a helicopter without them -- but with the V-12 they are placed on the side of its massive fuselage. Weird, right? But this is BIG weirdness as the V-12 is commonly considered to be the largest helicopter in the world. How big? Think of it this way: see that 747 over there -- that monstrous fixed wing machine? Well, the V-12 is as wide as one of those 747s. But unlike a 747, the V-12 can take off straight up, and haul close to 55,000 pounds at the same time -- or 88,000 if it takes off a bit less like a helicopter and more like a plane.
"On August, 6th 1969, Mi-12 has lifted cargo in 44205 kg on height of 2255 m, having established a world record of load-carrying capacity for helicopters which is not beaten till now."
Mi-26: The biggest operational helicopter in the world
Don't get close, or even approach it when the rotors are spinning: "this chopper's wash will pick up and fling rocks, up to 12 inches in diameter, around like leaves!". With a crew of six, this "Halo" (NATO reporting name) mega helicopter can carry 70 passengers, or a flying laboratory, or a whole dump truck, with space to spare...

When compared with a typical Chinook, Mi-26 does indeed look big
Mi-12 is significantly bigger than Mi-26

"November 2003, a U.S.-led coalition launched Operation Mountain Resolve in the Nuristan and Kunar provinces of Afghanistan. The above-displayed photograph of the precarious-looking rooftop landing by a CH-47 Chinook helicopter was taken during that operation by U.S. Army Sgt. Greg Heath. The Chinook helicopter is touching down to receive Afghan Persons Under Control (APUC) captured by members of the U.S. 10th Mountain Division"
As for the smallest helicopters, nothing beats this concept from Popular Mechanics Magazine, Feb. 1951
Compare it with the diminutive and very practical Soviet Ka-26 from the early 1970s (you could attach various functional blocks behind the pilot's cabin) - see image above, on the right. And then, there was a Hiller XH-44 Copter, which Stanley Hiller, being 19 years old, designed, built and succesfully flew - in 1944! - making it "the first helicopter with coaxial rotors to fly successfully in the United States."
Carter Copter is the proverbial small company "that could". It's been around for long time, and delivers results: their signature mini-copter has flown faultlessly since 2002

особенно понравилась пикча где Ми-26 рядом с CH-47 рядом стоят.

Отличная подборка! Спасибо.

интересно: вот эта концепция верто-самолёта ( там, где несущие винты расположены на вращающихся плоскостях крыла) оказалась почему-то нежизнеспособной, хотя со стороны очень изящное решение: взлетаешь как вертолет, потом переворачиваешь двигатели в горизонталь и идешь уже как самолёт

но в серию эти единичные образцы всё-таки не пошли и не прижились...
почему, кто-нибудь знает?

а черт его знает... ТТХ вроде как очень хороши, но вот тут пишут
http://www.lenta.ru/news/2005/10/21/osprey/

что морпехи его брать отказались.. типа слишком хорош.. но разве это повод для отказа ?

Это ВВС. Для спасателей.
А морпехи вовсю юзают.
Оспри вообще-то для корпуса МП и делался.
А летчикам его попытались "вдуть" за компанию, чего не продать еще-то?

Так что не надо обижать Bell:)
Вполне себе серийный конвертоплан, в использовании.
