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.

Is the internal designation H.S.8 explainable?
