Hesham - judging from the "Willis" [Hawkins] and "Kelly" [Johnson] inscription, I'd say that this is a "CL-1400" or "L-1400" alternate point design for A-X from Lockheed. I should also point out that I don't have the original item, just the .jpg.

Ok, looking at picture on a larger PC screen (as opposed to mobile phone screen), the picture is much more relevant - and much more intriguing aim9xray! :eek:

Hello,
Thanks to many of you for your compliments about my drawings.
I wanted to do them in more details and with colored plans and nice effects, but I did not have the time.
Now that this topic has emerged, my desire to depict those Lockheed AX projects is increasing. I hope to find time (and willingness) to start this. Maybe I could suggest this to Le Fana de l'Aviation!
Regards
Alain

Hi All -

Love it when we get a new donation at the Museum as you never know what you'll find. A donation yesterday had artwork for the McAir design and an interesting memo about McAir assisting, (well, at least discussing) with Boeing-Vertol on their A-X design. McAir never really put in much effort on the proposal so seeing this memo is interesting. File size is too big - will see if Overscan can add it to this thread.

Enjoy the Day! Mark

Going by that fantastic McAir artwork, Mark, I must say I'm impressed by it's rugged workman-like landing gear!

Thank's for sharing mate!

McAir put in effort on the 1967 concept formulation study contract but not for the 1970 AX RFP (probably too busy on FX).

Hello,

I'm looking for more informations on the Boeing project proposal for the AX program (the one with the YA-10). Does anybody have illustrations, 3 views plans or something else to help me? The only ilustration I have so far is the following (see in attachment).

Thanks for help.

Mark's memo is attached as PDF.

Note Boeing had 2 teams on this:

Boeing (Seattle) management discontinued the West Coast A-X effort using [turbo]fans on 16 July, and expressed confidence in Vertol's A-X configuration.
Wow, nice find and very interesting read thank you Mark Nankivil
Found it very interesting as to how much time and resources went into FOD and the cross-shaft redundancy (including cost estimates over the lifetime of the aircraft), and the perceived benefit of propeller over turbofan!

Fascinating

And another variant with a unswept wing and a slightly different engine nacelle set up. Note the substantial tailhook, not shown on the swept wing version.

Enjoy the Day! Mark

I've tried to restore this image. No idea what it is supposed to look like, but I think this is an improvement:
And one more attempt - I use your's work as starting point.
The result could be enhanced more, if we decide the camouflage' colors and then separately adjust the aircraft.

Yes, Sienar's version is the most believable one. Good work!

'After the war, Hans-Ulrich Rudel consulted Fairchild during the development of the A-10.'
(Source: https://aviation.stackexchange.com/questions/21197/why-was-the-engine-of-the-ju-87-stuka-not-replaced-with-a-more-powerful-one)

As a huge fan of the AX/A-10 and it's role, this is the first time I've heard of Hans-Ulrich Rudel participation in the AX program.

Hello,
Here are some work published in Le Fana de l'Aviation hors serie on the A-10. We decided to publish some of the contenders, it's always interesting. In order to make the plans a little bit "sexier", I had to invent some details (markings, some structures details, etc...), but I think they reflect quite well, what could have looked like those contenders. We did not represent all the competitors, they were so many, but only some of them.
Special mention, for the Boeing design, I had informations from a former Boeing researcher/engineer who helped me so that I could propose a good drawing example. There were lots of other Boeing designs, but I found rare information on them.
Regards
Alain

Good Day All -

Found these two sketches in the Robert Kemp Collection on the SDASM Flickr which seem to be AX designs.

Enjoy the Day! Mark
Are we sure these two sketches are legit? In both the ejection seat triangles are drawn upside down.
