Giants of the Sky by Bill Gunston
ISBN 1-85260-258-9

LOCKHEED MARTIN C-5 GALAXY: WarbirdTech 36


In 1960 the USAF launched Project Forecast which called for the world's biggest logistic transport, the CX-4, in the 600,000 lb category. It should be a jet. The only study I know comes from Douglas but I have no details about its Model Number. I guess that Boeing and Lockheed carried out its own designs.

With all the data generated under CX-4 study, the USAF launched an specification for a CX-HLS aircraft. The winner was Lockheed (C-5 Galaxy)

Douglas submitted several designs: Model D-890, D-895, D-900. According to "Giants of the Sky", the definitive design was D-916 while D-920 was the submission for the Wardbirdtech volume.

I have included to this post the D-920.

The last scan is Boeing C-5A from Giants of the Sky. Anybody knows Boeing's model number for it?

I agree with scott opinion about full-scale mockups. The SST produced three of them (2707-200, 2707-300, and L-2000). The first vanished without a trace. The second only saved its nose, and after 40 years spent travelling across the United States. As for the L-2000, the FAA took it from Lockheed and used it for SST passenger evacuations, and then it was scrapped. A pity, really.

The Shuttle full size mockup survived only because the Shuttle kept evolving over the years and decades, and Rockwell had to keep up with the changes brought by NASA.

(P.S. I hope this info hasn't already been denoted )

Unbelievable. 200 000 pages, 5 months to read them, and then Lockheed managed to fool the U.S generals.

Oh, found this information from The C-5A Galaxy Scandal: A $5 Billion Boondoggle by the Military Industrial Complex by Berkeley Rice very interesting!

I just stumbled upon this early concept art of a 757. It seems that the 757 was intended to be another large maybe even larger plane than the 747 instead of being a smaller single-aisle airliner it became. Unless this was just a concept of ANOTHER plane called the 757 which doesn't have any link to the real 757 and was just using the next number after 747.

 

[Hobbes]

Where did you find this?

 

[fightingirish]

It is a Boeing CX-HLS proposal with the model number 757, which was used later again.

It was called SOR-214,

and GE/Convair and Martin proposals were rejected.

So, I have heard that boeings design was considered superior and was recommended by the usaf but McNamara choices the Lockheed proposal because it was cheeper (and obviously they under bid) now what i have not been able to find is why the boeing design was considered superior, because from what I can find (wich isn't a lot) is that both proposals were practically the same.

I found out that Douglas Aircraft, as part of CX-HLS (C-5) studies, created an entire hypothetical Sino-Thai conflict in Thailand to study the influence of C-5 deployed forces on the conflict.

Hmm, interesting and thanks RyanC...Douglas playing on the Domino Effect perhaps?

Is it just me or does that "Lockheed concept" models wing-box/wingroot look extra chunky and unaerodynamic?

P.S. I think it goes without saying, that the Boeing Concept appears to be much more aerodynamic than either Douglas' or Lockheed's design

My dear Pioneer,

I think the Boeing model is more dynamic, as I said, but less practical in term of performance.

Thanks hesham for sharing the article. I find the following snippet intriguing , given the extent that that a Chook has to be stripped to fit within the Lockheed C-5.

One of the first C-5A models is given a final inspection before testing in the Arnold Engineering Development Complex 16-foot transonic wind tunnel at Arnold Air Force Base in the mid-1960s. The wind tunnel, also known as 16T, is part of the AEDC Propulsion Wind Tunnel facility. PWT was designated as an International Historic Mechanical Engineering Landmark in 1989.

Do you think the lower left hand image is a cargo variant on the Douglas D-974? Edit: Do you think you could find the original magazine as well?

Hi Baffledboar,

I think it was a cargo and also trannsport aircraft project,for Aviation magazine,
please see;

Aviation magazine international : les ailes, l'air et l'espace - 18 années disponibles - Gallica

And from Putnam's book.
