    I read a article in a Military Aviation magazine about a B-17 that was converted after the war to Turbo Prop engines. The guy had two he was going to convert but the first one crash if I remember right and the second was never done. I think the use was for firefighting. Does anyone having any pictures or information on this plane? Thanks

    These two pictures came from the book B-17 by warbird tech.

    Thank you for finding these pictures. This is a very interesting aircraft. I found the magazine that the article was in. It was July 2006 issue of Fly Past. I assume that posting a scan of the article or photos would be a no no?

    Posting pictures and quoting the source of the photo is fine. There are instances where you can not find the source. Usually they are posted as unknown and if a source found is usally corrected by another member.

    The converted B-17F used Rolls-Royce Dart turbines same as what were on the Vickers Viscount....They had named her "The Batmobile" prior to her crash.

    One of the Forts used for the tests is now "restored" as "Liberty Belle" and was done by Tom Riley at his former base in Kissimmee, FL. I saw the plane back in 03 when I was there and have a few pictures--I'll try to find those and post them. If I'm not mistaken, Air Classics magazine had a nice write-up not too long ago about the plane as well as the history of the 5-engine project.

    Wow! Yeah, I guess the B-17 would have been a little "overpowered" with four turboprops; as a guess, I would say the turboprops put out about twice the SHP as the "standard" Wright Cyclones.

    Well, at 8 lbs. / gal., Water is one of the heaviest naturally occurring "chemicals" (for lack of a better word) around.
    I imagine that plane held a LOT of water, so I bet there was some internal reinforcement of the structure, when it was re-designated as a fire bomber.
    At that point, it may have been found that the original powerplants were a bit...er, lacking in power, trying to take off with a full load.

    ...and 38 years later, Wenatchee STILL looks like that! ;)

    OVERPOWERED - there's no such thing! I guess it depends on which specific model of the turboprops went in for how much shp they generated.

    Unless the engines start tearing apart the airframe!

    See - that still doesn't mean it's overpowered. It means that the airframe is structurally weak! :lol:
