Dornier has started work on the WW version of the Do-24 seaplane. The major difference between the historical plane and the WW plane is the engines: where the historical plane used Jumo-205 diesels or Wright Cyclone or Bramo-323 gasoline engines, the WW Do-24 is being initially offered with the new Jumo-208 diesel radials (though other engines can likely be fitted upon request). First flight is expected in mid 1935.

The ususal suspects show keen interest.

Pencil in some orders from Argentina...

Regarding Do-24: Yesterday I had a chance to get as close as 3m to the last flying Do-24 which is in Friedrichshafen again. I was also told there might even be a chance to get inside if I´ll be back on sunday and if not too many other people are around. The planes´s not open to the puplic generally but if I´m lucky....

Many "if"s but I´ll give it a shot. Would be just too cool. The B-17 I was in looked bigger than the Do-24 but turned out to be horrobly cramped. Guess the old flying boat hardly offers more space. Can´t imagine to fly around the world with such a plane. Gives an idea what´s going on at the Great MrRobertson Air Race.

Here's what Dornier's come up with for the Dutch. The version for Germany is focused on air-sea rescue work, so it removes the machineguns, fairs over the tail turret, installs beds in the cargo space for rescued personnel. and instead of some of the range of the Dutch version carries raft bundles under the wings (for those times when the seas are too rough to land or there are more people to be rescued than can be carried in one plane)..

Turkey is also looking to replace its older Rorhbach flying boats.

Do 24, remains popular.

Give 'er some torpedo capability, say a couple of fish and American Engines, and you might be looking at an order from Mexico.

As to American engines, the Jumo 208 is going to be produced by Pratt & Whitney (it's the result of some collaboration between Junkers Motoren and Pratt & Whitney). Or you could fit Wright Cyclones. The raft bundles the German planes are using could be replaced with torpedo racks without any difficulty

A version of the Do-24 tailored for Mexico.

I'm gonna make you all drool:



Do-24 is the one near the camera. A Catalina is seen behind it. A Tante Ju is seen at the edge of the image.

-pic taken at the spanish air museum. I won't clutter the board with the pics of the Bf109 with Hispano engine, the He111, the Ju52, the B-25, the F-5, F-104, F-4, Sabre, Texan, Saab Viggen, MiG-15/21/23, and a LOOOOOOOOOOOOONG Etcetera...because I don't want to make people drool too much .

Enough for now

I counter with high-res photos of the last flying Peashooter and Seversky. ;o)

Pics of the Do-24 in Friedrichshafen once the stuff is downloaded from my girlfriends camera.

Damn...good counter!!!

So sad that I don't have a scan of the pic I have inside the cockpit of a spanish EF-18A+...

Or the one where I'm sitting at the F4U1's cockpit...

That would be hard to challenge ,hehehehe

I probably could - with pics I took inside a B-17 on display during the Planes of Fame Airshow 2005. The bomber was later shown in flight. Problem is I didn´t have a digital camera in 2005 and would need somebody with a scanner....

Here's the version that the German Air-Sea Rescue Service is buying. The listed payload is to carry raft bundles under the wings for situations where either the seas are too rough for the plane to land, or there are more people in the water than the plane can rescue.

Planebuilder does allow for you to change the efficiency of the engines on the "Powerplant" page. Altering the efficiency box will change the speicific fuel consumption (in lbs/ hp-hr). Planebuilder gives the "normal efficieny as being between 20 and 25% for piston engines which is a bit off. Example would be the Allison V-1710 with a fuel consumption of 0.66lb/hp-hr (15% eff) the RR Merlin (about 17%). THe really, really good ones can get up to 22% eff or so. For diesels, maybe 24-25% eff.

In response to the Do-24 pics, I offer this;



The record setting CANT Z.508

Hmmmmm. I hadn't read the "efficiency" box as fuel efficiency, more as engine efficiency. But it DOES have the right effect. Have to go see what happens..... (Not to mention the effects on the Fw-187, when the efficiency of it's engines goes down.)

OK, here's a revised version of the Do-24K. The maximum weight went up by 1.5 metric tons, to cover the increased fuel capacity, everything else stayed approximately the same. Maximum weight is still within historical bounds for the type, if not by a lot.
