Dietrich-Gobiet/Dietrich Flugzeugwerke Designations

Dietrich Aircraft Designations

Richard Dietrich Flugzeugbau GmbH - 1922, Mannheim

Dietrich-Gobiet Flugzeugbau AG (DGF) - 1923, Kassel
-- Merger with Anatole Gobiet's Belgian engineering firm

Dietrich Flugzeugwerke AG - 1927 Teltow (Berlin)
-- Solo project w/o Gobiet, Raab, Katzenstein, or Hall

On Dietrich designations: I have seen 'DP' defined as 'Dietrich Passagier' but have no way of confirming this. Then there is the single 'DS' designation ... perhaps for 'Dietrich Schule'? 'Dietrich Sport'? Who knows?

______________________________________________________________

Maybe it would be appropriate to ask here; does anyone know if there exist three views of the Dietrich Gobiet VIIa, IX and DS.I? Besides a few pictures floating around on the interent and some specifications I did not manage to find anything? Many thanks in advance!

I went in to replace '404' links but ended up re-writing all of the Dietrich-Gobiet entries and correcting the corporate history bits.

Any additions or corrections to the Dietrich-Gobiet list would be most welcome.

This item from L'Auto Italiana of 10 March 1924 supposedly depicts a "Dietrich D.P.U." As there was no such designation, I was tempted to think that the "U" was in error for "V", therefore "D.P.V" Unfortunately, the D.P.V used a Mercedes, not Siemens Halske engine... What type is it, then?

L'Auto Italiana seems to have mistaken the Roman numeral 'II' for a 'U'. Their 'Dietrich D.P.U.' is a dead ringer for the prototype DP II Bussard (which lacked interplane struts).

I have the DP II listed with 63 hp Siemens Sh 4 radial - but that 5-cylinder engine originally produced 55 PS.

Thanks! I had a feeling it could be the D.P.II but needed some expert advice on the subject.
