More holes than filling but here's a start on De Schelde designations. Can anyone fill gaps or add other designations?

Hi,

S-8 small airliner with Jumo Diesel engines,data from 1935,project only
S-32 project for dive bomber
S-33 project for speed mailplane
 
Thanks Hesham.

I'm wondering if the S.33 high-speed mailplane is the model/mock-up you have added to the "De Schelde bomber aircraft" thread.

http://www.secretprojects.co.uk/forum/index.php/topic,5276.0.html
 
The De Schelde S-33 was a single seat/single engined high speed aircraft
mentioned in "De Nederlands Vliegtuigencyclopedie-Schelde musch en Scheldemeeuw"
as a racer.

The first De schelde aircraft was de S-12, a four seat low wing tourer powered
by a 130hp Gipsy Major.

'S' indication stand for Slot the designer who before worked for Pander.

Thanks Lark. Obviously not Hesham's three-engined aircraft then!

And before that, Theo Slot worked for VIH (Vliegtuig Industrie Holland). :)
 
The 'Scheldemusch'
and 'Scheldemeeuw'

never received an official De Schelde 'S' designation, only just their name.
 
Thanks for the corrections, Lark.

That makes better sense of the serial numbers. I noted that the De Schelde numbers follow on from Pander c/ns -- 47 was the last Pander E (c/n 24/I rebuilt). Then:

De Schelde S.12 c/n 48
De Schelde Scheldemusch c/n 49
De Schelde Scheldemeeuw c/n 50
De Schelde Scheldemusch c/n 51, 52, 53, 54, 55
De Schelde S.20 c/n 56
De Schelde Scheldemeeuw c/n 57

So, you've already told us that the S.12 was "a four seat low wing tourer powered
by a 130hp Gipsy Major". What the heck were the S.13 and S.14 ???
 
Actually, the S-4 design was the Pander Postjager.
Refer Wesselink, T and Postma, T, De Nederlandse Vliegtuigen, p. 87
 
Thanks Jos.

The overlapping Pander/De Schelde designations are all very confusing.

Lark said: "The military variant of the Pander 'Postjager' was the Pander S.4 'Militair' a planned medium bomber or long range reconnaissence aircraft."

http://www.secretprojects.co.uk/forum/index.php/topic,2742.0

I've assumed that the De Schelde S.4 designation would be applied to an on-going project (the Postjager having been abandoned with the collapse of Pander as an aircraft maker). De Schelde certainly intended to proceed with Postjager-derived military aircraft (see Hesham's post). Do you have confirmation that De Schelde also intended to continue with the Postjager itself?

Cheers

Jos, you have anticipated me ;D I was just preparing a type list of produced VIH and Pander types!

To your list, I can only add a few glider types:

Pander PH-1 Zögling - 1930. A copy of the Stamer & Lippische Z-12 Zögling ('Pupil', designed by Alexander Lippisch). Replica at the Aviodrome.
http://www.aviodrome.nl/themapark/expositie/collectie-overzicht/M-W.asp

Pander PH-2 Mayer - 1930. Copy of German M.1 sailplane by Hermann Mayer. Used by ENZC club.

Pander SG-38 (Schulgleiter) - 1940?. Licenced Schneider DFS 108-14 for NSFK (555 built). http://www.abpic.co.uk/photo/1093296/

I haven't come across a PH- designation for the SG-38. Come to that, I'm not even sure if the PH-xx are actually Pander designations (Dutch gliders of the time all seem to be refered to by their PH- registration markings - for example, see: http://www.grunaubaby.nl/baby_in_nederland.htm )
 
Herman Dekker's 'The Complete Civil Aircraft Registers of The Netherlands since 1920' lists registration PH-1 as a Zogling RRG and PH-2 as a Mayer M.1. So, PH s a civil registration, not a Pander designation.
 
I remember that a few years ago a Dutch aviation magazine
produced a multipage article about unbuilt 'De Schelde' designs.
(no drawings,only descriptions)
Unfortunately I can't find the concerning mag.and text.
Is there someone who who can remeber it and who haves the magazine?

Ah, so does that mean that (presumably like the SG-38) the licence-built Zögling and M.1 never received Pander designations at all?
 
A bit more about some De Schelde designs...

S.19 : two engined midwing 'jachtkruiser' crew of 4.Concept had much of the
Fokker ontwerp 193 who was much a G.1 loo alike.
S.22 : single seat highwing fighter with pusher prop driven by a R.R.II(?)
Two MG's and one canon in the nose,two in the wing.
S.24 : Isotta Fraschini Asso A 120R.CC.40 powered two seat combat aircraft.
High wing with pusher prop.
S.25 : two seat combat aircraft with gull wing and pusher prop.same engine as in the S.24.

abridged translation from an article by: F.Gerdessen in 'Luchtvaart' January 1998.
 
Hi,

the PH-3 was an open cockpit two seat light aircraft,a version
with 120 hp De Havilland Gipsy III,later modified to have an
enclosed cabin,only one was built.
 
Going through the Wesselink/Postma book I referred in an earlier post I came across (p. 18) the Carley S.1, a 1919 small aircraft. Slot was working with Carley in the early part of his career and this could be 'his' S.1 - although the book does not specifically state this.
The entire thing is, of course, complicated by the fact that Fokker used the letter 'S' extensively for its training aircraft.
 
Thanks Hesham,

That description fits the Pander P-3. I think we've established that PH-3 was simply the registration for a Zögling glider -- a German (Schleicher-built) RRG-1 according to Herman Dekker.
 
Verrry interesting, Jos.

What other Joop Carley designs are out there? I have Carley's L-11 biplane, the 1923 C-12 'Flying Bicycle', and the KLM 'Jumbo'.

The 'Jumbo' is too late to have involved Slot. But we know that the C-12 was developed into Slot's H.2 for VIH. So, going out on a thin limb ... if the Carley S.1 is also Slot's S.1, might Carley's C-12 have been Slot's S.2?
 
In my files,

there was also S-?,appeared in 1937 for de schelde light transport monoplane Project,maybe
taken the designation S-10 ?,only my suggesting.
