Kalkert KE.5 / Ksoll KE.5

[Maveric]

Are the two aircraft Kalkert KE.5 and the Ksoll KE.5 identical aircraft? Or one of both a derivative?

I know that both of them came about at the same time. The Kalkert development had a 30hp engine, the Ksoll aircraft a Bristol "Cherub III" of 36hp.

Both aircraft were high-wingers. Kalkert was indeed a designer, but it is said at Ksoll: He had a light aircraft build by an other man.

The Ksoll KE.5 received the aircraft identifier D-1227, from the Kalkert KE.5 I know no identifier.

Does anyone of you have more information, possibly photos?

Dear Maveric,

as I know,no relationship between Josef Ksoll and Albert Kalkert,even Ksoll type
five aircraft was called KE.V by Roman letter and not Arabic letter.

We need help B)

Maveric,can you send a drawing or a picture for Ksoll KE.V or 5 ?.

 

[Maveric]

I have nothing, see the first post.

Very strange,

I inverted the search,and track Kalkert KE.5 in this site,I know it was actually built,
but no evidence or a hint for it ?,I get all pages,maybe my glasses is not good,can
anyone confirm.

I have a photo of the Ksoll KE.5.

A similar photo of much lower quality of that plane is in the accompanying photobook of the "Typenhandbuch der deutschen Luftfahrttechnik".

 

[Maveric]

This is really fantastic. Many, many thanks...you made my day

Alas, the Aviation in Germany links are dead. The j2mcl Planeurs site may be a more useful source:

Ksoll KE.5 - 192? single-seat parasol monoplane; D-1227
- KE.5 : (??) no more details
- KE.5 : Presumeably, 'KE' was for 'Ksoll Eindecker' (??)

BTW, the usual spelling is Joseph Ksoll (eg: Flugsport) but Josef Ksoll is also seen (eg: pg. 7, Die Flugzeuge der Firma Stahlwerk Mark by Günter Frost, Arbeitsgemeinschaft Dt. Luftfahrthistorik. For the latter reference, I wonder if there is an unwritten inference that Ksoll's KE.5 might have been inspired by the Mark R III 22 lightplane? The two types certainly look similar.

[1] One 'issue' with this listing is a photograph mounted by ETH Zürich - "Ksoll 'Breslau' Caption: Pictures from the glider competition in Rossitten, 10.-16.5.1924". This image purporting to be Breslau shows a parasol-winged motor-glider answering the description of the Galgenvogel II (BTW, galgenvogel means 'gallows bird' or someone deserving to hang ... a bit dark ... is there another meaning?).

My description of Breslau is cribbed from page 79 of Dr.-Ing. Werner von Langsdorff's Das Segelflugzeug (J.F. Lehmanns Verlag, München, 1931). I would tend to trust Langsdorff but I do not really know which description is accurate.

Thank you my dear Apophenia,

frankly,this company was a mystery,even it's name (Kalkert),in another
encyclopedia,they called it Ramor ?!.

I think , the Breslau and Galgenvogel III is the same glider : Ksoll Galgenvgel III "Breslau"
