German Glider and Motor Glider Airplanes

[hesham]

From L'Aeronautique 1922,

here is some German glider and motor glider aircraft,most notable is Stuttgart F.V.S.5,Gotha,Casper Sb-3 and Hamburger
designs.

Zeise, Drude and Mesemann are interesting...

Hi,

here is some German gliders,designed by Haydn,Nihm,Huttmann,Winter,Wenk,Kirchner,King,Schule,Kupper
and Kohl,but not all of them displayed,and for Mr. King,I spoke before about him.

Hi,

the Akaflieg Dresden from D-B1 to D-B11 are known,except D-B3,D-B5 & D-B6,has anyone
a more info about them,and if there were a Projects or not ?.

The picture Nr 10 here : https://akaflieg-dresden.de/die-akaflieg-stellt-sich-vor/historie/ shows the DB.5 .

 

[hesham]

Any good drawing to Winter design ?.

 

[richard B]

also what was this,Hessen-Flug ?.

At the Rhön 1931 , a member of the Aka Hessenflug Verband showed this 1 m. span model (source : Luftwacht 1934)

Zeise

As I know Mr. Zeise designer a motorglider,was that right ?.

The Zeise-Nesemann Bird must have been one of the earliest examples of an aeroplane with retractable undercarriage!

 

[hesham]

From Aerophile 1934,

I never heard about it before ?,Mr. Mainingen.

 

[Maveric]

I believe Mainingen ist not the name of the constructor. Meiningen is a city in germany.

...

 

[hesham]

Thanks,and from Aerophile 1934,

the gliders from Maikafer and Zaunkonig.

 

[Aubi]

Maikäfer (Maybug, often incorrectly translated as Mayfly) and Zaunkönig (Wry) are names of the motor gliders, not designers. I found two gliders (sadly no pictures) named Maikäfer from that period, one by Hentzens and one by the DFS, the latter one is allegedly the first true motor glider and looks like in the description, so I presume this is it.

Thanks,and also from Aerophile 1934.

 

[Maveric]

This is not really a german design, but the Austrian Kittelberger WKM.1.

 

[hesham]

Huttmann

So weird ?,this name also repeated here;

[Apophenia]

As mentioned that French thread, this German designers name was apparently Hüttmann not Huttmann.

[Maveric]

"Mayor Wagner" (probably incorrectly spelled "Oberbürgmeistr" here) with a place of origin in Breslau. Until now, I was only aware of Akaflieg Breslau as a glider manufacturer, but I can't find any mention of a glider with that name. Perhaps you can help!

Actually, the correct translation for Maikaefer is ladybug.

 

[MichiK]

Actually, the correct translation for Maikaefer is ladybug.

No, it isn't.

The ladybug actually is the Marienkäfer (https://de.wikipedia.org/wiki/Marienkäfer).
The (Feld-)Maikäfer (https://de.wikipedia.org/wiki/Feldmaikäfer), as mentioned above, is translated as cockchafer, maybug or doodlebug.

 

[Nicknick]

Yeah, I have to agree.... I didn't read it well enough..

A much-delayed reply but ... the Breslauer Modell- und Segelflug-Verein „Schlesischer Adler" or the Breslau Model and Gliding Club "Silesian Eagle" designed and built the „Oberbürgermeister Wagner". This glider is mentioned in the Zeitschrift Flugsport yearbook for 1930 (No. 20, page 341).
-- https://www.pennula.de/zeitschrift-...segelflug-modellflug-flugzeuge-luftfahrt-1930

A machine translation reads as follows:

High-performance glider „Oberbürgermeister Wagner".

The aircraft, built by the Breslauer Modell- und Segelflug-Verein „Schlesischer Adler", exhibits several deviations from the usual design of high-performance gliders. To achieve a significant weight reduction of the spar, the wings of this aircraft are braced by a covered cable. With an aspect ratio of 1:17.4, the aircraft has a wing loading of 11.6 kg/m² with a safety factor of n. The cable is pre-tensioned and dampens wing vibrations more effectively than struts.

During a four-hour glider flight in strong winds, the pilot could not detect the slightest vibrations. However, this was a glider flight exclusively in slope lift, and since the aircraft reached an altitude of 480 m above the launch point, it soared in the uniform air currents. The aircraft is built using G.535 airfoil in the usual single-spar construction with an auxiliary spar.

Wingspan 18.1 m, wing area 18.4 m², empty weight 144 kg, glide ratio 1–22°.

Earlier in the magazine there is mention of a flight made by the „Oberbürgermeister Wagner" in June 1930 (although there is no suggestion that this was a maiden flight).
