German Helicopter Prototypes & Projects

[hesham]

Hi,

The Wagner Roadable helicopter.

 

[hesham]

Hi,

Who has a more info about Germany Dieter Zierath Z-1 which
was never completed ?.

 

[Jemiba]

"More than one hour late on job, traffic jam on all flight levels and
absolutely no landing places in the city ! It was sheer terror !"
Perhaps we should be glad, that still yet all efforts to build a cheap
and easy to fly helicopter didn't come to fruition !
Here's the one from the german aerotechnik GmbH, built and flown
in 1969. Four rotors on movable arms, driven by BMW engine of 54 hp.
Flight control is achieved by tilting the individual arms, so eliminating
the need for cyclic control. With the arms folded, the heli could be
parked on an area of 1.98m x 2.18m, a two-seater was envisaged.
Nevertheless, the car in the background looks more attractive ! 8)

(from FlugRevue .7.1969)

VFW-Fokker concept from 1975.
I can't say, how the rotors mesh.
Found in Flug Revue, November 1975, page 7

 

[hesham]

New concept for VFW,


thank you for sharing my dear Fightingirish.

 

[Jemiba]

"... the concept reminds to the Fw 61.." the caption says. I rather think, it reminds to
the Flettner Fl282, as the Fw 61 had no intermeshing rotors.

New to me is this Fluro Libelle helicopter of 1956. This two-seat ultra-light was built by Fluro (W. Schlieske, Helpup (L)), and was powered by three Schmidt-Argus jets fitted with afterburners (photo by Thomas Herminghaus).

From the following site :http://www.stadtarchiv-heilbronn.de/publikationen/online_publikationen/heilbronnica_5/_files/qf20-15-seitz-merckle.pdf

Walter Schlieske, former fighter pilot and engineer for the RLM, had started to build a “Flugroller”
(flying scooter),short “Fluro” in 1952. It should have a five bladed rotor, powered by a VW engine,
should be able to take off with a crew of two,reach a speed of 150 km/h and cost around 4 to 5,000,-
DM, a real “olkshubschrauber” (peoples helicopter). That project actually triggered Karl Merckles
interest in this kind of aircraft and made him start his own company. Mr. Schlieske founded the
“FLUR-Flugroller and Hubschrauber Entwicklung” (FLUR flying scooter and helicopter development )
in Minden/Germany and built the Libelle, powered by a 100 ccm two-stroke engine and tip ramjets.
The small helicopter should cost 8,000,- DM for the single seat and 14,000,- for the twin seat variant,
Both built from aluminium tubing and bamboo ! But the claimed flight proved to have been faked,
the company was just bogus and Schlieske went to jail in 1957.
So, not really what we call a “project”, I’m afraid !
:-\

WOW, great Jemiba...
the M-101-GK on side 31 is absolutly fantastic... :-*

YOU MADE MY DAY :

Hi,

Mr. Havertz designed and built a five helicopter prototypes,from HZ-1 up to HZ-5,pages
48 & 49.

[hesham]

Hi,

here is a strange single-seat very light helicopter prototype of 1959/60,the designer
called Heinz Schmidt,page 54;

http://kulturserver-nds.de/home/hubtest/medien/Neg.Nr.GUN.pdf

 

[hesham]

And from page 54 also;

there is anther unknown designer for me,Mr. Gerhard Siegel,I think he was from
Germany,and his mystery project ?.

Hi,

Here is a compund helicopter Project,designed by DSH (Deutsche Studiengemeinschaft
Hubschrauber).

 

[Apophenia]

Going way back, but the 'big gyro' in Reply #3 is a retouch of stock-standard H-34 SC+253 of MFG 5 (c/n 58-1569), later 80+81. Apparently, that airframe is now being parted out in South Africa.

An obvious Gyrodyne lookalike...

Austrian helicopters do not (yet) have a specific topic and are to be found in the Austrian aircraft topic for now:

Hi,

was there any more Info about Krauss TRS-111 helicopter of 1970 ?.

http://www.aviastar.org/helicopters_eng/krauss_trs-111.php

 

[Jemiba]

An autogyro, not a helicopter !
... and sometimes you'll find the designation "TRS-3", because three "1" can be read as a roman 3 ....
And we shouldn't forget Stingrays great list !

[hesham]

OK my dear Jemiba.

Fliegergruppe Kornwestheim

Thanks.

 

[Maveric]

Fliegergruppe Kornwestheim (Krauss) TRS.1

 

[Jemiba]

Thank you, Maveric ! Maybe interesting:
Your post show the TRS.1 with the registration D-HOLY, whereas the aircraft in the Hubschraubermuseum Bückeburg
(helicopter museum Bückeburg) is registered as D-HOKY (photo via http://www.bredow-web.de/Hubschrauber/Krauss_Autogiro_TRS1_EN/krauss_autogiro_trs1_en.html)
It is said, that just one example was built, but why should the very accurate guys from the museum should have
changed the reg ? Perhaps there were two aircraft, after all ?

 

[Maveric]

the webside of the Fliegergruppe Kornwestheim shows another example....

 

[Maveric]

and the Fliegergruppe Kornwestheim HRS.1

Just a minor nit: I think Maveric's photos show D-HOCY. The apparent "L" in "D-HOLY" is actually a rather square "C" with glare hiding the top section of the letter.

There's another online picture saying that "D-HOKY" is indeed a mistake, and that this aircraft is actually D-HOCY as well.

[hesham]

Amazing find my dears.

 

[hesham]

Can I ask if there was TRS-2 ?.

 

[Maveric]

I have no informations about TRS.2.

 

[hesham]

From L+K 6/1969.

 

[hesham]

From JAWA 1969,

here is a small Info about VFW H4.

 

[edwest4]

Thank you everyone.

 

[Apophenia]

Going back to the Fliegergruppe Kornwestheim autogyro, is this the same Ing. Peter Krauss later connected with the Gyroflug SC01 Speed-Canard?

Hi,

here is a flying-bus helicopter,designed by Mr. Walter Schlieske.

Hi,

here is a strange helicopter Projects,designed by Mr. Hans Lemmerzahl,it had one main blade
only ?,the first was from 1954 and second was from 1959,the later had paddle wheel ;

People's helicopter Lemmerzahl HL 1
In 1954, the German designer Hans Lemmerzahl won an international award for his design for an inexpensive
helicopter. The double seater should fly with just one jack screw. The project was not realized, but today a
single-bladed helicopter seems to be up to date again.

[Basil]

The first concepts of the Bo-105 were also planned with a single-bladed rotor. Any idea what's the reason for these asymmetric rotor layouts?

Wait a minute, the same Walter Schlieske that made the Libelle under the fraudulent FLURO company heading? That's an interesting find and adds another layer to the story that I wasn't expecting!
