Various DFS Projects

DFS Jabo mit Lorinantrieb - March 1944.

What was this ?.

Looks like a ramjet tube with aircraft bits stuck onto it and a pilot in the nose. Rather like the Skoda-Kauba P.14 but smaller, lighter and fitted out as a bomber rather than as a fighter.

DFS Jabo mit Lorinantrieb - March 1944.

Wow! Never seen this before. The DFS did many research on ramjets. But a Jagdbomber (fighterbomber) on this basis seems fairly absurd to me. Was it only an intellectual game...?

It doesn't look quite so ridiculous when you see the full 3-view, which I will publish at some point. It's essentially a long tube with wings, a tail and cockpit with the pilot lying on top of the intake (just like the Skoda-Kauba). It's not that dissimilar to the Me 328 or BV 40 in being a lightweight design that would have needed towing aloft using a trolley.

Thank you my dear Dan.

Looks a fairly small intake for a ramjet, more of a letterbox intake under the cockpit pod. An interesting design for sure.

You twisted my arm. Here's the front.

 

[hesham]

Amazing drawing my dear Dan.

 

[Hood]

Ah, so the pilot is hugging the back of the circular intake. Makes more sense now.

A project for Fieseler company,it was a twin boom aircraft and its
fuel was the Hydrogen,and powered by three engined,two tractor
and one pusher,the Hydrogen could be stored cryogenically in large
tank towed by the mather aircraft,the aircraft had a very strange
shape,I never see like it before,it had also a ring wing.

From my dear Dan's book,

the Fieseler Project looks like this design very much.

 

[Maveric]

This project had nothing to do with the Fieseler Company.
It is the DFS "Lotos" anti-submarine glider.

Posts moved and merged to the appropriate thread.
Maveric is absolutely right, of course ! Recommended for further reading is Dan's latest
"Secret Projects of the Third Reich" issue.

Having thought on this a bit, could it have been towed by the big bungee cords they used to use for gliders? Or a ground mounted engine driven pulley system?

 

[hesham]

From, Luftwaffe over America,

what was DFS-240 ?,and it was not a misprint,see the index.

 

[dan_inbox]

Apparently, yes it is an error. Every other reference to D-IEXX mentions a DFS-230, incl http://www.airhistory.org.uk/gy/reg_D-a12.html which mentions it as "used for Mistel tests".

The index was probably simply generated by software from the text, so if there was a typo in it then it goes to the index automagically...

And,

I found these drawings of the DFS 346 dated August 6 and October 10, 1944 on page 47 of Dan Sharp's bookazine Secret Projects of the Third Reich. As noted by Sharp, the DFS 346 was given the internal designation HS-8 and appears to have been influenced by an Arado supersonic research aircraft project called Überschallflugzeug (supersonic airplane).

 

[Vahe Demirjian]

I also found this wartime drawing of the DFS 346 from the Siebel project documents on page 12 of the bookazine Secret Designs of the Third Reich, also written by Dan Sharp, and it too has the same contour of the rear end of the vertical stabilizer and Padder seen in the DFS 346 that was tested at TsAGI's T-101 wind tunnel.

 

[hesham]

also the DFS.301 was unknown project and may be it was
related to development of DFS.346.

What was the reality of this ?,

DFS.301 possibly allocated to DFS for development of DFS 346

What was the reality of this ?,

DFS.301 possibly allocated to DFS for development of DFS 346

The designation DFS 301 is associated with the postwar Soviet OKB-2 346-P - a wooden [edit: wooden-winged] glider prototype. (I'm assuming that suffix 'P' was for prototip - прототип). This airframe was sent to the USSR for testing in 1947 - first in a wind tunnel, then to be repeatedly dropped from a reconditioned Boeing B-29.

I'm not sure if the rocket-powered OKB-2 346-I and 346-III also bore the '301' alternative designation ... or whether that was distinct to the 346-P.

As noted by Sharp, the DFS 346 was given the internal designation HS-8 and appears to have been influenced by an Arado supersonic research aircraft project called Überschallflugzeug (supersonic airplane).

Here is a report on the DFS 346 (HS-8) by the German Ernst Udet institute in November 1945, translated for Bell Aircraft. It includes an original German plan at the end.

[Maveric]

Is the internal designation H.S.8 explainable?

DFS-360 flying disc project as Mistel aircraft

From a reliable Dutch source,now it's gone from Internet,

In 1945 werd door DFS aan het ontwerp DFS 360 gewerkt. Het zou worden gelanceerd vanaf een Mistel combinatie (DFS360 bovenop een ander vliegtuig)en was bedoeld om vijandige bommenwerpers neer te halen. Het toestel was een versterkte houten schijf met een diameter van 30-40 meter die was beladen met vloeibaar explosief materiaal en zou worden aangedreven door 6 Argus 044 pulsejets. Deze aandrijving zou het toestel een stuwkracht bezorgen van bijna 3000 kg en het toestel met een snelheid van 965 km/u voortstuwen. De explosieven zouden zich vooraan het toestel bevinden, de brandstof zou in verscheidene tanks rondom in de schijf worden gemonteerd. Voor de besturing was een TV camera voorzien. Het was de bedoeling dat dit toestel bij botsing met een vijandelijke bommenwerper de explosieve lading en de resulterende brandstof zouden ontploffen en zo de grootst mogelijke schade zou aanrichten. Of de DFS 360 reeds werd gebouwd is niet geweten, maar het TV geleidings-systeem was tegen het einde van WO2 reeds op punt gesteld. Om de DFS 360 onder verschillende hoeken te kunnen lanceren werd overwogen om bovenop het moedervliegtuig een draaibaar lanceringsplateau voorzien.

Translate,

In 1945, DFS worked on the DFS 360 design. It was to be launched from a Mistel combination (DFS360 on top of another aircraft) and was intended to shoot down enemy bombers. The aircraft was a reinforced wooden disk with a diameter of 30-40 meters that was loaded with liquid explosive material and would be powered by 6 Argus 044 pulsejets. This drive would give the aircraft a thrust of almost 3000 kg and propel the aircraft to a speed of 965 km/h. The explosives would be located at the front of the aircraft, the fuel would be mounted in several tanks around the disk. A TV camera was provided for control. The intention was that this aircraft would explode the explosive charge and the resulting fuel in the event of a collision with an enemy bomber, thus causing the greatest possible damage. Whether the DFS 360 was already built is not known, but the TV guidance system was already perfected towards the end of WWII. In order to be able to launch the DFS 360 at different angles, it was considered to provide a rotating launch platform on top of the mother aircraft.
