Lockheed Advanced turboprop transport concepts

I am familiar with that but cant remember at the moment what it is (probably from Lockheed). I am also sure that I have this drawing in colour. BTW the posted document is worth to download, because it contains a lot of pictures and drawings of various unusual transport planes (spanloaders, WIG, Lockheed Flatbed, etc..).

Yes my dear Matej,

I remembered that I sent a picture shows a Lockheed Model aircraft with turboprop
engines but I don't remember it now,it look like the first aircraft here;

Nice! It does give technical insights into certain areas and is worthwhile for the irresistibly ironic image below alone!

I'd caption it the An-700M ;)

Lockheed Turboprop Cargo Aircraft Systems Study, November 1981 found on NTRS


Lockheed Georgia study on Advanced Turboprop transport aircraft. From page 102 on, study for possible dual civil-military role for a Propfan transport aircraft. Configuration No.3 was modified to USAF's C-X specifications.

The artwork on the last page is very similar to the Lockheed 4-engined Propfan concept in Post 1.

Seems like Lockheed put a lot of effort in the Propfan concept, with the Cl-1320 RECAT, various Civil and Military transport conepts and the PTA testbed.
