Dornier Stingray (formally planned as "Libelle")

Some Data, I found at the local newspaper.
wingspan : 9,00 m
hull length: 6,60 m
height: 2,31 m
maximum weight: 650 kg
basic weight : 400 kg
engine: Rotax, 115 PS
travel speed: 140 - 160 km/h
max. speed: 200 km/h
min. speed: 68 km/h
Range: 800 km
Seats: 2
Price: 100.000 to 150.000 Euro

The Do-24S will have only up to 33 passengers and used for commercial flights and as a fire-fighting plane.

AFAIK, the Stingray is the "rebirth" of the Libelle from the '20s.

"has a wings partially folded" ???

Meaning what exactly?

The power plant selection sounds like the Sea Star, but that aircraft uses twin 650hp engines for a 12 passenger aircraft.

I think, it's a mixture of several independent informations. As Frank already
pointed out, an aircraft for 33 to 45 pax with just 900hp don't seem really
plausible. The Do 24ATT, a modified Do 24T has three 1125hp PT6 engines
and hasn't this capability.
The "partially folding wings" to my opinion are a feature of the stingray (Libelle)
2-seat amphibian, just as the original had for better stowing. To fold the wings
of a passenger a/c seems not very logical to me.
And ... what's a "partially" folding wing against a "fully" folding ?
It would be good again, to know the source ... ;)

Shouldn't that be Dragonfly and not Stingray?

ah, but the reason the Do-24ATT doesn't have the capability is due to size. With 3375 HP, it woud be able to carry them for sure. 450 Hp PT-6s would be derated lower than the lowest I recall, about 550 HP. Could they really be 1450 HP?

Hi all,

For the engines for Do-24S,the P&W Canada is from optional to use
it and not sure,and for the wing I have an artist picture to it,but I can't
send it,it is clearly different from your imaginations,it is high gull wing and
of which not straight but like V shape.
The Libelle is the second and it would be of aluminium construction
with an MTOW of 750 kg and would sell for 100.000 Dollars.

That's my opinion, too. But a Do 24S (without a hyphen ;) ) should be based
on the Do 24, as we now it, I think .

Then it's no Do 24, I'm afraid ... :(
The rights for the name "Dornier" still lies with the Dornier family, I think,
but the "Dornier GmbH" is producing automatic weaving looms today. The "Dornier
Technologie" company, which is developing the Stingray (so called on its presentation
in Oshkosh) is owned by Iren Dornier, the grandson of Claude Dornier. But an a/c
of that size probably would overstretch the capabilities of that company.
And as traditions are regarded quite high there, a totally different layout from the
original don't seem to be pausible to me.

A long as we're on the Do 24 (no hyphen) :) ISTR reading some time way back, of an updated version to be powered by two (yes, 2) R-2800s. I can't recall the country or the proposal, but I was wondering if anyone has any other info.

That sounds like a modification to the old Do 24T ( which for
example served in Spain until the 70s) to keep them alive.
Re-engining with two R-2800 would have given the Do 24 at
least 1000 hp more power, compared to the original propulsion .
Probably the last true Dornier project based on the Do 24 and
really intended for production, was the Do 24/72, which was
considered as a joint venture with France.

Hi,

I check from the Do-24S and I found that it has a gull-wing
and able to fold upwards to allow it to park easily in harbour,
but I can't send aritist picture to it.

Even without any picture, it would be very interesting to know, if
it is a genuine Dornier project, which nowadays would mean designed
by the Dornier Technologie company, or a project by another company,
just based on the Do 24.
I googled for Do 24S, but the result just gave the plural of "Do 24" :mad:

New to me, but the pic says "Dornier LAF" - meaning 'Light Attack Fighter' perhaps?

Looks like it has a nice flat belly for lots of ordinance...

Dornier Do 28C

The Do 28C was a derivative of the Do 28A and B, fitted with two Astazou II turboprop engines
with 530 hp each and a new nose,l enlarging the cabin capacity from 6 to 8 persons.
It was mainly intended for military purposes, but remained on the drawing board.
( from Der Flieger, December 1963)

Hi folks,
in the December 2011 issue of the French Magazine "Le fana de l'aviation" there is a very interesting article about the STOL aircraft Do 29. The article also has a company artist concept picture showing the Do 28C, a proposed (eight-seat?[1]) version with two Turbomeca Astazou II turboprops. Dornier used the fuselage of the Do 29 V2 for the Do-28C mockup.

There is also a 1-page article "Do-28C - Der unvollendete Turboprop" (Engl.: "Do 28C - The unfinished turboprop") in the German magazine "Flugzeug Classic", May 2002, page 45.

Not a complete new project, but the use of an existing type adapted to the use as
an amphibian. Due to the rugged design of the Do 28D and its size, I somewhat wonder,
why this project wasn't pursued further.

One wonders if the prop arcs weren't too close to the water.

I've only ever seen this project designated as "Leichtes schwebefähiges Kampfflugzeug" (light fighter
with the ability to hover), probably to indicate, that it wasn't just intended as a VTOL aircraft, but
also to launch its weapons from the hover, like a helicopter. At least, this was the explanation given
back then in the '70s ...

hesham, you are not required to speak every foreign language of course... But when you are faced with a text like this, you can easily re-type it in Google Translation and select French > English (or French > Arabic) to obtain a translation (that's what I do for many languages). That will prevent things like this to be written. I have edited your post to remove the erroneous designation and prevent it from appearing in search engines...
