Hi,

I have a small info about that DFS-528 which designed in Institute
for Aeronautics in Munich ,as high altitude powered glider intended
to climb in power to some 60.000 ft,and powered by P & W JT12A-6
turbojet engine.


Correct the title.

I have an article from Flugwelt 2/1960, were a DFS 582 is described, a high-
altitude research glider. But engine is given as a BS Viper ASV 11.
Dimensions would have been span 30m, length 13,60m, maximum altitude is
given as 17.000 m.

The Viper and the JT12A aren't that different in thrust. I suspect either could be used for this program.

Full details for this project appeared in Jane's All The World's Aircraft in 1965 or 1966?

In general appearance, it looks like a miniaturized U-2?

The really odd detail is the astoundingly long jet pipe. I'm sure the intension was to place the turbojet as close as possible to the center of gravity, but you really do wonder about the inefficiency of such a long exhaust?

Please correct me if I'm wrong?

Well, the long exhaust pipe is going to cause some possible problems (for example, the long exhaust pipes on the Merlin III/Merlin IV/Metro II TPE331 engines cause some definite starting problems - when the TPE331-10 was installed on these aircraft, the engine control computer went through several iterations to solve all the problems Fairchild-Sweringen encountered, many more problems than either Mitsubishi or Aero Commander did installing the same engine, but with short exhausts). On the other hand, if you added some scoops and mixing vanes to blend in cooler outside air with the hot exhaust, you could drastically reduce the IR signature. Personally, unless there was a drastic need for the long exhaust duct, I'd keep it short.

It seems to me it was very long program (1960-1965) and the real aircraft was never built...

It was actually built at V.F.W. (VFW P.58) but never finished ...

Amazing amazing amazing my dear Richard,

you made my day,of course we know that; the Vereinigte Flugtechnische Werke GmbH was formed December 1963,by merged of Focke-Wulf and Weser, other shareholdersbeing United Aircraft, Friedrich Krupp.AG Weser and Hanseatische Beteiligungen.

And I know there was a series for Weser,began with P.1 and reach P.58,it's weird ?.
