Please forgive me if this has been posted. I thought I read somewhere, that Lockheed was proposing a "Connie" equipped with turbo prop-jet engines. Are there any pictures of this prototype. And, would it have had faster crusing speeds than the Elecktra?

Actually the US Navy was test flying it. I think it had the same motors that the C-133 had.

Anyway from what I remember reading in "Tiger Tales' the two Navy frames where aquired by the Flying Tiger lines because they where built with cargo doors. The Navy when they surplused them had cut the wings off outboard of the MLG. So tigers aquired to other Connie wings and put those one the fuselages to create two relatively inexpensive cargo birds with normal plants.

Yes Lockheed built 6 in total for the US Airforce and Navy,they were designated R7V-2s and powered by 4 Pratt and Whitney YT-34P-12A turboprops.

Interesting concept. It actually looks very nice (though the radial version still gets my vote for the most beautiful propliner). Here's a pic of it I found on google:

I think you will find that Lockheed built 4 of these aircraft, with the P & W engines each having 6,000 Shaft H.P. They were built so that both the USN and Lockheed could gain experience of operating large aircraft with Turbo Props. Two were transferred to the USAF as YC-121Fs and first flew in September 1954

The USN put their R7V-2s through many test achieving a max dive speed of 479 MPH and a max Take Off weight of 166,400 pounds

The fourth R7V-2 was loaned back to Lockheed and fitted with an
Alison 501 Turbo Prop engine in the No 4 position so as to develope the engine for the 188 Electra aircraft. When refitted with it's normal P&W engine it was one of the two transferred to the USAF.

L-188, the story I heard was that Flying Tigers had damaged one of their aircraft up in Alaska and the fuselage was beyond repair so they used one of these Turbo Connies which had become surplus to Requirements to get a cheap fuselage and bolted it onto their wings. Mind you that is only the story I heard.

I like the Radial version better. The Radial Connies are a piece of aviation history.

just to add:

the Turbine powered Connie was offered to airlines as the L1249 Turbo-Constellation. Very little if any interest...

Quoting VC10 (Reply 4):
in the No 4 position

What's the logic in placing a test engine in the #4 position, where it would have the most pronouced effect on directional control?

As I recall, in that TWA exec's book he explains the turboprop conversion was the whole point of the new wing that eventually appeared on the 1649. When P&W (?) dropped the civil T34, Lockheed wanted to drop the development of the new wing, but TWA wouldn't let them.

Are there any other photos of the turbo-connie... close ups of the wing/engines perhaps?

Great thread! I never knew there was a turboprop Connie or that it was offered to airlines and rejected. These are the kind of threads that I joined a.net for - to learn! Thanks a million to everyone on this thread. Appreciate it!

I think you will find the turbo- prop conversion were a military led program to evaluate the use of turbo props over long distances, rather than a manufacturers idea.

In fact the Connie was not the only old recip that got turbo props as two
C-97 were also given them and the USAF called them YC-97J

The TWA vice-president was Robert W Rummell (or maybe Rummel). I think his book on TWA came out in the 1990s.

It looks a little strange with turboprops, although still a beautiful aeroplane... and the turboprops do give it even more grace in a weird sort of way.
But it was a piston design, meant to remain that way; the best three engined airliner in the world  Wink I'd love to fly on one but I doubt I'd get the opportunity.

Yeah it looks a bit like a Bristol Britannia!
