Russian Flying Fortress: Kalinin K-7

John Frazer said:

It makes some sense from aeronautical sense, if you can power it and if materials can do it. Both points turned out to be very much in question.

But those naval destroyer-sized wheel pants.... it's amazing they left any capacity for any payload.
Those are the bricks that are involved. The rest of it except the tractor-truck crew section and engines as streamlined as a Russian farm tractor, is all-wing. "Minimal" booms to carry the necessary tail.

It's sometimes called a "flying wing".

Those impressive photo's are not from the real aircraft. Those are later "fantasies".

However, the Kalinin K-7 was reality, but crashed and killed 14 people.

The inventor, Mr. Kalinin, was executed as "enemy of the state". I think it was because his machine didn't work, not espionage.

Now, how'z't for incentive to get the F-35 to work (giggle).

In case anyone is confused about the Kalinin K-7's size, it was truly large for the 30s, but not as big as those internet creations betray. From Russian Aircraft 1875 - 1995 Bill Gunston (Osprey 1995):

Span 53m (173ft 10 1/2in) length 28m (91ft 10 1/2in) wing area 454m2 (4,887ft2). Range was 1600km (994 miles), cruise speed 180km/h (112mph) ceiling 4 km (13,123ft). From the outset the machine suffered vibration through the tail booms. During engine run trials in June 1933 before its first flight it was discovered that it suffered severe vibration at certain engine speeds - a portent of what was to be its demise.
