B-29 pattern work [not a Guzzi]

Jet engines are the work of the devil!

True statement.  When you take them apart there is not much interesting, unless you get into the geartrain.  A compound supercharger on a 28 cylinder corncob, now that gets interesting

Quite an engine.  Took this pic at an air museum near Phoenix (CAF.) Imagine being assigned to do a spark plug change on a Consolidated B-36.

 The Piaggio P180 is the most unique sounding aircraft I've ever heard , was told it was because it is a pusher , and maybe that is part of it , but having heard other pushers , the P180 still sound different .

Pushers definitely sound "different."

The Piaggio P.166 is an older design that doesn’t have a tremendous amount in common with the Avanti except for wing mounted turboprop engines and pusher propellers, and it makes a very similar sound. So it must be something that arises from that particular configuration.

I've flown this Variviggen.   Strange airplane, although it flies sort of normally.

The Starship was another pusher and had a very distinctive sound.

Yeah, a local guy flew one for a while. He liked it.

Cessna ran an ad shortly after the Starship came out showing that you could actually operate a Citation (business jet) cheaper than the Starship and have a host of other advantages.  Beech knew the writing was on the wall before they delivered the first one.  But, it sure was a stunningly different looking airplane.

Interesting article on Titanium and it's use in, among other things, supercharged B-29 engines in CycleWorld by Kevin Camaron.
He went on to say that if there was a backfire into the supercharger the Ti would ignite leaving the crew between 30 and 60 seconds to exit the plane prior to wing collapse.

This is a video of the engines being built, kind of heartbreaking that it was all scrapped

Thanks for that!  I sometimes wonder if we would be *capable* of doing that again..

Considerin RR for thier trent engines "grow" thier high speed turbine blade simlar to a crystal so the structure is optimised at a molecular level, I'd say yes it could be done, why you would do it on the other hand is a whole different question a turbo prop as fitted to things like the C130 is more reliable a lot lighter and makes more power. I'm sure i've mentioned it before but aircraft stuff has a fatigue life you can endlessly rebuild it, the second law of thermodynamics catches up with everything eventually.
