Hello to averybody, and happy 2007! ;D

I have found this profile of a civil derivate of the Myasishchev 3M (M-4 "Bison") bomber. It was designated M-29. I think it´s an interesting design, I would be very grateful if you have more drawings / pics, and some data of this project.

P.S. Did the guys from Boeing thought of a similar design based on the BLUFF? ;)

One of the nice Nekrasov drawings. He closed the website with his artworks after differences with K. Udalov (drawings were planned for another Myasishchev encyclopedia) :(.

I believe to have seen more information in the Red Star vol 11 (Myasishchev M-4 and 3M - The First Soviet Strategic Bomber), but - as usually - I cannot find my copy for the moment. Could anyone confirm this (to help Golfus)?

Four model pictures from www.ussr-airspace.com (Alex Panchenko's models) in the attachment.

B-52 airliner project existed. I'll scan a pic tonight

*snicker* Not to mention all the times that stock footage of B-52 landing gear tests were used in TV and movie shows to depict airliner landing gear deployment. ;) The original "Mission:Impossible" tv show used this a good bit. (*chuckle* Yes, I'm showing my age, I watched that as a teenager "way back when")

There was also a "super guppy" version proposed & I've seen a drawing of a more conventional 'oversized' cargo version somewhere.

Thanks lark, your post was incentive to dig through piles and boxes like a mole. So I've found my copy. Here's the model picture.

Golfus, please send a PM, if you're interested in details of M-29 development history.

Judging by the preproduction, XB-52 style cockpit glazing, this is a very, very early concept.

Boeing was very wise to invest in the 707 instead of this monster.

Can you imagine how uneconomic an eight turbojet engined airline would have been, even in the late 1950s?

The large capacity airline really only became viable with the advent of high bypass engines.

I agree with you. Although Boeing studied several configurations for future jet airliners, their effort concentrated in B-47, B-52 and C-97 derivatives. At the end the 707 originated from the C-97 ancestor.
In my opinion it was the logical choice.

Found via a random trawl though the following page... Looks like a model of the military version of the M29 at the Museum of the Moscow Aviation Institute...

Funny, I happened on the same photo yesterday (following the exact same link as you) and thought of sharing that photo, but then I found myself unable to identify it... Actually I don't think this model shows the M-29 at all, since it's clearly a double-decker design, reminiscent of the Convair Model 37 or USAAF XC-99. Also it's a much bigger aircraft than the M-29/M-6P ever was meant to be.

Good Evening to All,

This aircraft appears to have a "flat" wing design... no dihedral. Does anyone know the purpose of not designing in any dihedral on an airliner? Sorry for the dull question, but I found this interesting.

Dihedral provides stability in the roll axis. The pilots (or the autopilot) would need to constantly fly the aircraft just to keep it upright.

Hello from Texas

Required dihedral is dependent mostly on wing location(low, mid or high) and wing sweep. Rearward swept wings have a sort of natural dihedral and dont require as much, or in some cases anhedral.

My understanding is that the 707 came from the 367-80 Known as the dash 80 in Boeing circles.

Thank you for responding.

Both the M-29 3-View and the Double Deck designs appear to lack dihedral. Sienar may be correct that perhaps the wing has enough flex to bow up in-flight creating some dihedral effect.

I've always flown modern aircraft with dihedral designed wings, where the pilot can relax and fly using just the rudder to hold course. I read an article about a recent flight across the USA in a flat-wing 1920's Cessna built before dihedral was known, and the pilot commented that it was exhausting because the aircraft would constantly roll to either side. He couldn't take his hand off the yoke.

You misunderstood what I wrote. Sweeping wings rearward increases the effective dihedral, in some cases to the point that the wings will need to have anhedral.
