Default A B-17 with five engines

The following link has some pictures of this curious and unusual version of the Flying Fortress, used to test the engine Wright XT-35 Typhon. I hope you enjoy and I count on your visit.

Thanks for the photos Pampa! That huge turboprop was planned for the B-52, but it eventually lost out to the J-57. The Russians had a similar idea, and built the "Bear".

The Russian had a similar idea, or stole the idea?

In several of the pictures it looks like the turboprop in the nose is the only engine running, with the other 4 engines canned/feathered. Cool

The crew probably could not stand the noise of 5 props!

This airplane was eventually returned to original configuration. It was, unfortunately, the B-17 that set down in a field (2013, I believe, and I think Illinois) with a fuel leak. Everyone walked away, but it burned to the ground.

Fire trucks couldn't get to it because of the soft ground of the field.

The plane had been recently overhauled, and instead of using fuel bladders, they went with a wet-wing.

The sealant didn't work.

Gotta hand it to 'em, they and "their Germans" produced the world's most powerful turboprop engine.

Stalin may have been a terrible person but I like his pragmatic approach to R&D. Let the West spend all the money on developing new technology and then wait for it to either crash in the USSR, the West to sell it to them, or a spy to steal the plans.

The USSR may have failed but it is hard to gloat looking at the cost of the F-35 alone!
