Re-engined Do-24. How And Why?

Wed May 21, 2008 10:44 am

I saw this lovely pic:

I looked up the aircraft and found that production stopped in 1945. Those engines are modern turboprops, apparently P&W PTBA-45. The original http://en.wikipedia.org/wiki/Dornier_Do_24 seems to be engined with radials.

My questions are: Would this be a lot of work? Why would they do this? And finally (tongue in cheek): Isn't this "defacing" a historic aircraft?

This is a pic of the Do-24 that Iren Dornier, the grandson of the famous aviation pioneer Claude Dornier, rebuilt to fly the route the late Do-X took around the world. This plane itself was a piece in a museum for a long time and Iren had to take her to the Philippines for restoration and admin purposes.

There's a great book out there, "Logbuch der Träume" in German, describing the whole spirit, the long way back to flying condition etc... official website

In my opinion it's not defacing a historic aircraft, since having this beautiful bird back in the air probably wouldn't be possible using just original parts. And I guess we all agree, a plane should be flying through the air and not sitting on the ground waiting for it to be turned into someone's next ten-pack...

Very well put! Big grin

The Do 24TT not only has turboprops replacing radial engines, it has a whole new wing. It was developed as a testbed for new technologies that Dornier had developed.

First time I have ever seen an aircraft that looked better in the water than it does in flight.

It's intriguing that a pre-WWII aircraft was used as a technology testbed in the late 1970s/early 1980s, (according to the website). Part of me thinks this is unusual, and another part of me reckons that Cessna has been doing it for a couple of generations now...

And it is now an amphibian - the original aircraft was a pure flying boat.

IIRC, Dornier wanted to highlight the company's heritage.
Exceptions confirm the rule.

From the Wikipedia article:

Quote:
The first two aircraft built were fitted with 447 kW (600 hp) Junkers Jumo 205C diesel engines.



Quote:
later models used the BMW Bramo 323R-2

Maybe you could re-engine her to Wright R-1820's (another historical engine that apparently at least a few Do-24's were built with), but it sounds like that, for the vast majority of Do-24's, you'd better also be an expert at maintaining now-obscure German aero engines if you wanted to maintain the aircraft's "purity"  Smile

Well it certainly has that effect, yes!

It was re-engined because the replacement parts supply line for 1940s-era BMW Bramo 323R-2 engines is just too long, these days.
