Erwin Musger Aircraft Designations

[Cy-27]

I read with interest the earlier posts on Musger projects :

http://www.secretprojects.co.uk/forum/index.php/topic,14070.0/all.html

I have started a list of the gliders and aircraft Ing. Erwin Musger (20 March 1909 - 16 March 1985) worked on in Austria.

So far we have:

Mg.I - Open cockpit single-seat Glider named “St Polten”. Design dated 1932. Span 18.00 m / Length: 7.10 m / Height: 1.95 m / Wing Area: 16.5 sq m / Empty Weight: 152 kg / Take-off Weight: 232 kg

Mg.II - Open cockpit Glider rebuilt from the “St Polten”. Started 1933. Span 17.25 m / Length: 7.10 m / Height: 1.95 m / Wing Area: 15.8 sq m / Empty Weight: 152 kg / Take-off Weight: 232 kg

Mg.III - Single engine low-wing monoplane (OE-DMG) with Mercedes F-7202 engine. Single seat enclosed cockpit. 9.5 m span and 5.90 m length. 1937.

Mg.IV - Single seat glider adapted from the Mg.II named “Pechvogel “ 1934

Mg.V(?) Uhu (Owl) - Single-seat school glider 1935 named "Uhu"

Mg.9 - Two seat glider named “Kamerad” 1936.

Mg.9a - Two seat glider with enclosed cockpit (OE-DUO) 1937

Mg.10 - Dated 1935

Mg.12 - High wing open cockpit single seat glider named “Primus” 1937

Mg.12a - High wing open cockpit single seat glider named “Ameise” 1938

Mg.15 - Sporting sailplane 1937

Mg.19 - Two seat glider with enclosed cockpit developed from pre-war Mg.9a 1952

Mg.19a - Twin-seat glider with enclosed cockpit developed from Mg.19. At least 20 built in Austria. Design started 1953

Mg.19b - Two seat competition glider 1953

Mg.19c - Two seat competition glider. Took part in 1956 World Championships in St Yan France

Mg.19s - Two seat competition glider. One off (OE-0517) from 1960

Mg.20 - Light aeroplane for sport and touring 1947/48. Crew: 1+1 / Engine: 1*80 or 100 HP / Span 10.50 m / Length 7.10 m Height: 1.50 m / Wing Area 13.30 m²

Mg.21 - Light aeroplane for sport and touring

Mg.23 - Single seat glider, competed in 1956 and 1958 Worls Gliding championships. First flight 25 June 1955

Mg.23SL - Single seat glider, at least 17 completed from 1962

Mg.25 - Tourer first flew 10 August 1956 . Crew: 1+1 / Engine: 1*65 or 95 HP Continental / Span: 9.20 m / Length: 6.90 m / Height: 1.70 m / Empty weight: 380 kg / MTOW 610 kg

Mg.26 - A twin-boom motor glider 1953.

Mg.27 - Motor glider which first flew on 29January 1953. Crew: 1 / Engine: 1*30HP / Span: 13.20 m / Length: 6.20 m / Height: 1.05 m / Wing area: 12.5 m² / Empty weight: 195 kg / MTOW: 325 kg

Base information from the earlier posts from Maveric with some supplemental data from Luftfahrzeugbau in Osterreich by Reinhard Keimal (ISBN 3-925505-78-4 Aviatic Verlag)

There are several gaps and queries and I am sure these can be filled by our Austro-German experts.

Very great work my dear Cy-27,


I did't see this topic before,and here is a drawing to Mg.III from Flugsport 1940.

 

[walter]

Thank you for this interesting list
Under the Mg.25 and Mg.27 headings a date of a first flight is mentioned. That would mean these 2 types were built and flown, but sofar I was unable to unearth photos, if they exist.
Anyone with better luck

This is the only photograph of the M-211 I could found (on the net). Does anyone know of more photos of the M-211?.
The D-EMIS registration was allocated since the sole M-211 was completed in W.Germany by Motorenfabrik Otto Wimmer OHG (there were restrictions on aircraft construction in Austria at the time).
The M-211 is also referred to as the Wimmer R-110

 

[hesham]

Hi,

Please,I want to know the relationship between this company and the Oberlerchner,
which developed Job-5 & Job-15 ?.

Hi,

Please,I want to know the between this company and the Oberlerchner,
which developed Job-5 & Job-15 ?.

So far I know , no relationship : they only were Austrian .

Please , have a look there :
http://www.secretprojects.co.uk/forum/index.php/topic,1562.15.html

where the story of the Wimmer R-110 is told … The grand-father of the R-110 was the Arado Ar 79 : van Nes worked at Arado in the thirties and forties .


I already post a second picture of it .

Thank you my dear Richard.

Hi to all

Last year I wrote: "Thank you for this interesting list

The date are 10 August 1956 for the Mg-25 and 29 January 1953 for the Mg-27.
Is it safe to assume tbat this info is not correct and that the Mg-25 and Mg-27 were in fact never built and/or flown and remained pure project? (unless I missed something)

 

[hesham]

As I know this company only built the Musger sailplanes,it was called Oberlerchner, or
Josef Oberlerchner Holzindustrie.

I've decided to post my version of Erwin Musger designations list. I dont' think it adds much new to Cy-27's list but there's a few links and corrections ...

Maveric also posted drawings of two 1947 Musger designs for tailless 2-seat light aircraft. Alas, no designations are known for these two tailless projects.

[1] This horizontally-opposed 2-cylinder was designed for the 1924 Mercedes-Daimler L 20 lightplane and L 21 light twin (original output was 19 hp). The 22 hp F7502 displaced almost 9L but the 19 hp engine may have been closer to 7.5L. This would explain the designation -
F (Flugmotor) 750 (750 cc) 2 (2-Zylinder). A used engine chosen for its availability and relatively low price.
