Title: The SSW Thread
Post by: Wingman81 on October 27, 2007, 12:51:02 AM
Hello mates.
I found an interesting article in Flight Magazine, March 13, 1919 about one of my favourite SSW D.IV  :-cool

Hello all

Thanks for the link Wingman

I see that from a forum to another you have the same favorite plane

SSK D III is a beauty too isn' it ?

It is wonderful to see this airplane preserved  :-ok Or this is replica?

Under the photo they said in deutsh

"Der Leiter des Internationalen Luftfahrt Museums in Villingen-Schwenningen, Manfred Pflum,
 fertigte in jahrelanger mühevoller Kleinarbeit einen 1 : 1 Nachbau des Jagdflugzeuges Siemens-Schuckert D III nach Originalplänen aus dem Ersten Weltkrieg an. Etwa 6.500 Arbeitsstunden sollen nach seinen Angaben aufgewendet worden sein. Er schleppte die Maschine mit einer Flugzeuganhänger 800 Kilometer über die Autobahn zum Luftwaffenmuseum. "

I kenne nicht mehr Deutsch but I think that this plane is a replica  for which 6500 Hours were
needed to be rebuilt-May be i am wrong, but I think that, sadly, no original DIII or DIV subsist
to day

Brunno:

You have it right the SSW is a replica.

Did the germans ever wing out the cooling problems with SH engines?

Hello Leo

On first batch the Siemens Halke engines were enclosed in large cowlings and over heated and even sized up !!!Not to be forgotten that we were at the end of war and than German was in hurry to find news models -The second batch of fighters was modified with a cutaway at lower section of the engine cowling
Later The SSK DIV was better but had engine over heating too at high speed-

Hi Brunno:

I believe these engines were lubed by castor oil.  That was an item not tobe found in Germany or AH.  They used a ersatz product which was not as satisfactory,  Did that contribute to the overheating and seizures?

Yes, a print from the 60s from an unknown aviation buff's collection. I wonder what is the underground material under the plane and the wood in the background looks so strange in B/W. Like Amazon rain forest but had to buy it for a clear shot  :-green

Any detail about this? All I know it is a 1916 manufacture. Interesting camouflage.

Another image from Nico Braas collection- is this SSW?
Title: Re: The SSW Thread
Post by: Wingman81 on November 25, 2007, 11:56:46 PM
I can rule out, its not a SSW D.III nor D.IV. It looks to me more Fokkerish. An alien aircraft to me. Fuselage would fit with Fok. D.V but Fok D.V has only 2 pair of interplane struts this has 4 pairs. Fok D.IV is ruled out for tail rudder shape. D.III fits but i know it only with half open motor block.

I think its either a to me unknown Fokker type or a captured allied aircraft (or an unknown SSW model but it looks very untypical for an SSW at all, rudder doesnt fit propeller and motor covering also not)

This would be nice for Breguet Challenge  ;)

Hello all
Nice to see it's possible here to have breguet 's challenge too :))

I think  i should have been the winner

This plane is a Fokker DV which was too much slow to have any chance to get service !

Must be noted that it was the first designe of rheinhold Pflatz (the famous  fokker s' head designer )

Hi Bruno,

image I put is the from Siemens web site but I can not find correct address. I have get it long time ago and in meantime I have two times instaled PC system and many of bookmarks are failed to recover. Link is interesting :))

I cant find the link either but i had swept through this page some time ago and found some images:

I was amazed when i opened my small booklet "The Siemens Schuckert DIII&IV" Profile Publications by Peter L. Gray © 1966
On page 3 i find the image i posted under post #13 in this thread. It is not a SSW D.III but SSW DIIc D.7551/17 a long wing span prototype. According to Mr. Gray it flew first in Oktober 17. I had assumed it might be  a prototype because i could not find any other D.III with a 2 bladed propeller. All regular production D.III i have seen have 4 bladed propellers.

Damn interesting- four balde propeller! is it reason why this airplane was very good in intercepting and climb?

Damn interesting- four balde propeller! is it reason why this airplane was very good in intercepting and climb?

Might be but main reason will be the motor concept of the 160 H.P. SH.III engine. I will quote a short passage from Mr Gray's publication:

[...]
In the Siemens engine the crancshaft revolved in one direction at 900 r.p.m. while the crankcase and cylinders rotated in the opposite direction, also at 900 r.p.m. This achieved a virtual engine speed of some 1,800 for an airscrew speed of only 900 r.p.m.; the obvious main advantage was in increased airscrew efficiency.[...] (p. 4, P.Gray, The Siemens Schuckert DIII&IV, Profile Publications 1966)

It is later said that: in further the developing of the motor the engine was fitted with twin magnetos and speed was governed by a proper throttle control, sensitive down to about 350 r.p.m. This was a considerable advantage over most rotaries of the period which ran flat out and were only partially controlled by a "blip switch" which cut the spark altogether for as long as depressed, or by a control  which cut the spark to certain cylinders, which system (in the Gnôme Monos) had a serious attendant fire hazard. (p. 5, P.Gray, The Siemens Schuckert DIII&IV, Profile Publications 1966)
[...]
Another advantage in the Siemens engine, over standard rotaries, was that a considerable degree of reciprocation was achieved in the opposite rotation of the cylinder and crankshaft masses which accordingly reduced the gyroscopic forces[/b].
(p. 5, P.Gray, The Siemens Schuckert DIII&IV, Profile Publications 1966)
