Early German Projects & Prototypes

Did anyone hear about this designer ?;

Pioneer amphibious Project. Poland Germany,

In July 1912, Lucius Lange exhibited a model of a monoplane of his
own construction, a seaplane with floats and a wheeled landing gear
in Jan Wlekliński's cigar store in the Bazaar. The structure was easy to
assemble and disassemble. In the event of a failure in the air, it could
be disassembled in the air and the aviator could be rescued with a
mechanical device replacing a parachute.

Never heard of... Curious to know more!
 
You would wonder if it was meant to be some sort of powered rotor kite for use by Kaiserliche Marine ships as a aerial spotter. Get it aloft with a high speed tow, and then use a small low powered engine to help keep it airborne without its mothership having to keep moving all the time?
 
My dear hesham, I searched my printed sources and can't find anything on a Mr. H. Grimmer.

Searching the internet with other words than "Hubschrauber" I found the following two references (with "Grimmer Schraubenflieger 1909"):
Both are apparently some kind of an index to the source you mentionned.

Nothing more than this comment is found: Modell mit verstellbaren rotierenden Flächen (Schaufelrad) 1909.

In my humble opinion, the project of Mr. Grimmer was one of the numerous ideas of those days, whether or not serious, and mostly forgotten.

Rumpler-Haefelin Monoplane (Rumpler-Haefelin 1910 Eindecker)

Dr. Albrecht Haefelin was associated initially with the firm of Rumpler (see https://www.secretprojects.co.uk/th...t-and-ideas-from-1908-1940.21616/#post-255036) before starting the Flugwerk Haefelin & Co., GmbH, Berlin (this thread, reply #10).

Haefelin Armoured Monoplane (Haefelin 1911 Eindecker)

In 1911 the firm built a steel-based monoplane, the Haefelin 1911 Eindecker. This was developed as a military armoured monoplane. The aircraft was fabric covered and made of steel. The fuselage was of stainlesssteel sheet and accommodated two seats and the engine. To reduce air resistance, the seats were slightly inclined towards each other.The front section was fork-shaped and the aft section conical. The front section was connected to the centre section via a bayonet catch.

Compared to contemporary conventional fuselages at that time the steel fuselage was lightweight, low drag with high strength and was weatherproof. The main undercarriage was made of steel tubes and resembled that used on the Bleriot IX but was sturdier. The Haefelin monoplane was fitted with a tail skid. The aft of both wings could be warped across the entire span.

An armoured military version was evaluated at Doberitz in March 1912 after a successful 85 minute flight with a pilot and one passenger.

The WWI Aero article stated that the Flugwerk Haefelin & Co manufactured versions with 30 hp, 55 hp, 70 hp and 100 hp engines.

Details

Wing span: 11.5 m
Overall length: 9.0 m
Fuselage length: 7.5 m
Wing chord: 2.25 m
Wing Area: 20 sq m
Empty Weight: 320 kg
Fuselage Weight: 28 kg
Engine: 1x 70 hp engine
Crew: 2

Further to my last post of the Hermann Dorner glider, I came across a treatise which talked about his life. One of the more amusing factors regarding his glider was that the towing device was no less than a plow horse, by which I would guess they mean a shire breed.
Apparently Hermann directed the animal's gait with a whistle. This is how unconventionally the career of one of the first German aircraft designers began. However on one of the early attempts apparently the glider overturned before take-off due to the oblique pull of the horse!
 
Here's some pics of the Dorner III model, of which particular note is the engine arrangement, where although the engine was placed in the front, a shaft drove a pusher propeller behind the pilot and passenger.

I have my doubts concerning the so-called Jeannin biplane (Gray/Thetford, p. 429). It is not of Jeannin style (a biplane with swept wings), and apparently it was designed by Karl Bomhard, who worked for Union and built there a number of other swept winged airplanes.

My dear Tuizentfloot,

here it's.

I am curious as well about the Gray/Thetford entry mentioned in reply #179.

I know there were two Jeannin's, Emile and his brother Heinrich.

Heinrich Jeannin was a co-founder and director of Argus engines who provided powerplants for Aviatik in Mulhausen (Mulhouse) .

Emile flew as a test pilot for Aviatik. The image in the Putnam book page 429 is very similar to the Aviatik P.14 design but with a Benz engine. It could have been built as a close copy of the Aviatik design that Emile had flown while at Aviatik although the Schmitt/Schwipps book states that ".... from 1914 onwards, the military administration increasingly relied on the scissors-type double-decker. This also ended Jeannin aircraft construction.", inferring that only Taube monoplanes were built.

Emile Jeannin, as an aircraft constructor,was based at Johannistal and was best known for his Taube (Stahltaube) types between 1910-1913.

did anyone hear about Hirth Type-A (Taube)?.
Click to expand...

I haven't but anyone could build a Taube copy since Igo Etrich held no patents for his design. But Hellmuth Hirth was chief pilot for Edmund Rumpler before moving to another Taube-builder, Albatros.

That doesn't mean that Hirth didn't plan to build his own Taube ... I'm just not sure what his incentive would have been. Perhaps Hirth considered going into Taube production for himself before realizing how over-crowded the field was?

Anyway, lots of the German-built Taubes had 'A' associated with them - I presume this sprang from the Idflieg's A.I designation for the type.

I have it as N.F.W. (forgotten source )
 
Hello everybody, I've just discovered the posts about Clement Auff'm Ordt and can add some about him:

Bankier Clement Auff'm Ordt (also known as Barron Auff'm Ordt) was a former Strassburg Husar Lieutenant and a resident of Paris and Baden-Baden. In August 1908 he was allowed to resume his test flights on the Raststätter Exercise Ground in Germany, which he had begun in spring 1908 at Buc near Paris. In September 1908 he moved to another location for the tests (Iffezheim Horse trakts). The tested monoplane was constructed like an Santos-Dumont Demoiselle, but due to the sources, never flown successfully. 1909 Auff'm Ordt started new test flights at St. Moritz, but due to the hight of the city, the engine developed not enought power and the Biplane crashed into a snow-wall.

Hi,

Dr. Hübner designed a mid-wing monoplane,powered by

Dr. Hübner - Eindecker: Das Flugzeug vermittelt die fliegerischen Möglichkeiten anno 1912

Einen Eindruck von Qualität und Leistungsfähigkeit der Flugzeuge vergangener Zeit erhält der Besucher, wenn er den Dr. Hübner-Eindecker aus dem Jahre 1912 betrachtet. Der Rahmen ist aus Holz gefertigt sowie die relativ dünnen Tragflächen, die mit Stoff bespannt sind. Lediglich das Untergestell...
