Junkers Projects and Prototypes 1919 - 1939
« on: March 29, 2006, 12:26:30 am »
Well

Let´s break this topic with a two very interesting projects from profesor Junkers, both of them flying wings. The first one i found it in a websitre dedicated to junkers aircraft is the Junkers 1000 a colossus wich should be transport a lot of people, the design is from 1919, a very advanced aircraft for this time.

The second is another flying wing project of 1930, had six engines, i suppose it could transport a respectable amount of passengers. I would like to find more info about those old giants.

Saludos

Saludos Raravia!

You have info about this and a lot more giant aircraft from all times at "Giants of the Sky" by Bill Gunston. Ed PSL. ISBN 1-85260-258-9.

Prof. Hugo Junkers worked on a series of giant passenger aircraft

By late 1919, the JG-1 which was a civil version of its R.I bomber (a very advanced monoplane bomber from mid-1917. see The German Giants by GH Haddow and PM Grosz. Ed Putnam. ISBN. 0 85177 812 7) was cancelled by the Allied Control Comission when construction of the prototype has been initiated.
JG-1 had 4 Junkers L2a engines at 230 hp each latter changed to Liberty at 400 hp. Span was 125 ft (41 m aprox)

The R-Flugboot (giant flying boat) first drawings dated June 1918. It was intended to be powered by 12 engines about 1000 hp each. Span was 262 feet (86 m). Loaded weight: 48 tonnes.

In 1921 replaced the R-Flugboot with the Junkerissime. An all wing aircraft with twin booms it has to be powered by 4 Diessel engines at 700 hp each. Wingspan was 206 feet (68 m) and maximum passenger capacity was 60.

By 1925, Junkers completed its dream design, the J1000. Canard, twin hull and all wing configuration. Capacity: 100 passenger. Span: 262 feet. No information available about the engines. People boarded up stairs from the trailing edge.

A bigger desgign was proposed (I would love to see drawings about this monster): Wing cord between 19-20 meters, double decker layout. Span: 425-450 feet (140-148 m). Capacity: 100 to 1000 passenger

I have found nothing about this 1930 design attached to your post. But design data and weight (100 ton) could be applicable to the design I have described in the paragraph above, what do you think?

Dear hesham,

The Junkers Ju-77 is in fact the EF-77 project.(Entwicklungs Flugzeug)
 a further development of the Ju-52/3m.

In fact , all you ever wanted to know about Junkers is on:

Enjoy!

Junkers Seaplane proposal (J 40 ?)
« Reply #10 on: June 30, 2008, 10:55:16 am »
Hello guys,

the picture above ( "Hugo Junkers Pionier der Luftfahrt", Wolfgang Wagner, B&G ) only comes as a teaser, since my doubt isn`t exactly about this particular project, but probably an off-shot.

in August 1934 the RLM set a requirement for a reconnaissance seaplane with 5 to 6 seats. They were presented to Dornier, Hamburger Flugzeugbau and Junkers. The dornier project became the Do24, the Ha/Blohm&Voss application the Bv138 and the Junkers one turned to be a "DOPPELFLUGBOOT" proposal ( text taken from "Wasserflugzeuge-Flugboote...", by Hans-Juergen Becker, B&G verlag). Bruno Lange`s "Typenhandbuch der Luftfahrttechnik" only refers to it as a "ZWILLINGS-FLUGBOOT". Apparently it was to be a seaplane with twin fuselages, much in the line of the above portrayed.
Is anyone here enlighted in this "seabird"?

According to Fred Gütschow in de 'Die Deutschen Flugboote' Motorbuch - Stuttgart 1978
it should be a -1928- design for a ' freitragender Schulterdecker mit doppeltem Bootsrumpf'
(shoulderwing design with double hull)

No type number known.

Hi Lark,

nice to have you here. The picture relates to that particular project, but I am searching for a 6 year older design, also with double fuselage, a contender to the "Flying Clog".

Würger , in the book you mention "Wasserflugzeuge etc.." there a 1936
Hillman project for a double fuselage military flying boat project powered by four
engines (two in tanden).

Hillmann was the former chiefdesigner by Schütte-Lanz.Maybe he worked in
coöperation for Junkers at that time...

Hi Lark,

thanks for your concern. Unfortunatelly I only have a few copies from that book. Can you please transcript the text involved? I believe there is no sketch of this "bird", is it? All the best.
