Weird Airplanes 

“Through the ages there have been so many unusual inventions we deem them as weird and whacky flying machines. Some went on to become successful and others never made it from being just a proto-type. However, everything we publish here, infact did fly even though only one or two were ever produced.”

For Example this Ukrainian: Калинин К-7

Kalinin K-7 (Ukrainian: Калинин К-7) was a heavy bomber/Civillian transport experimental aircraft designed and tested in the Soviet Union in the early 1930s. K-7 was of unusual configuration with twin booms and large underwing pods housing fixed landing gear and machine gun turrets. In the passenger version, seats were arranged inside the 2.3 meter (7 ft 7 in) thick wings. The airframe was welded from KhMA chrome-molybdenum steel. The original design called for six engines in the wing leading edge but when the projected loaded weight was exceeded, two more engines were added to the trailing edges of each wing, one right and one left of the central passenger pod. However V. Nemecek states in his book, The History of Soviet Aircraft from 1918, that there was only one further pusher engine added; this agrees with the specification supplied far below.

Designed by World War I Aviator Konstantin Kalinin with a wingspan close to that of a B-52 and a much greater wing area, the K-7 was one of the biggest aircraft built before the jet age. It had one engine fewer than of the B-52 as well, having an unusual arrangement of six pulling on the wing leading edge and one pushing at the rear.

The K-7 was built in two years at Kharkiv starting in 1931.

The K-7’s very brief first flight showed instability and serious vibration caused by the airframe resonating with the engine frequency. The solution to this was thought to be to shorten and strengthen the tail booms, little being known then about the natural frequencies of structures and their response to vibration.

K-7 first flew on 11 August 1933. The aircraft completed seven test flights before a crash due to structural failure of one of the tail booms on November 21, 1933. The accident killed 14 people aboard and one on the ground. Although two more prototypes were ordered in 1933, the project was cancelled in 1935 before they could be completed. In 1938 Kalinin was executed as an enemy of the state.

    STEAMPUNK :o) The K-7 picture above is bogus.. The K-7 was real but the pictures aren’t. There pretty funny forgeries. Color photos in 1933? Seems unlikely. Todays “huge awesome fighting machine” post comes via the good ol’ Enlishrussia blog. They post great pictures of awesome Soviet era stuff, but it’s a bit disappointing that their descriptions tend to be between uninformative and completely fictional. This time the subject is a huge Soviet plane from the 30’s. About this they say:

    …modern history lovers in Russia try to reconstruct according the plans left in once to be top-secret Russian army archives their look in full color. This is one example based on ideas of Russian aviation engineers of that times.

    In reality it was a Russian 3D modeler by the name of Levin who modeled the huge warplane that might exist in some parallel universe where history turned out more like pulp scifi. I don’t speak any Russian so I have no idea if there are secret plans or if it’s just made up, but it doesn’t take away the fact that it looks great. And he made it even better and gave us a couple of pictures of the plane battling his older Nazi UFO model (Haunebu III to be exact – the same design you see in the Iron Sky teaser).

    Talking of this Levin guy, you should also check out his airship model – it’s another awesome steampunkish creation:

    More Bogus pix here but Russian text.

    My favorites – the K-7 engaging a UFO … It’s all good fun.

    Cheers! Jamie

      During our ventures through the dusty annals we sometimes run across some fantasic information that we know will garner the attention of our readers all over the world, whether or not the subject is fiction or real, it is still interesting, however, We must admit we are not smart enough to know everything that is real, nor are we dumb enough to believe everything we see and to think even could be. .
      With the K-7 example it made, it no difference real or not, the actual question is, would it be plausable to even think or believe it could ever get off the ground? Could you even muscle it off the ground and it fly? I doubt it, no matter the amount of power applied the angle would be that of a brick? Now I am not an areonautical engineer, but it brings up a great queestion doesn’t it?
      By the way, thanks Jamie, I really didn’t know the real story. But I did suspect someone was going to tell me it was not real…
      Yes, Jamie, I have been “PUNKED” ! 🙂 Thank you 😉
