ERNO LB 21 Bumerang
In 1968/1969 ERNO made a proposal to the German Research Ministry
for a lifting body development program
Phase I
To find the best form of the lifting body (LB) in a wind tunnel test of LB 01 to LB 21
Alloy Material test with Inconcel, René 41 or Haynes
Also oxide ceramic was tested as heatshield
Phase II
Unmanned Model for flight test in the subsonic range
3.10 meters long, 1.90-meter span, 0.87 meters Leitwerk height.
Weight 310 kilopound (stand so in the magazine!)
This is inclusive Senor facilities for flight data, the data transmitter, and remote control.
with help of the Erprobungsstelle 61 of the Bundeswehr
made drop test with a Transall C-130 aircraft, Bumerang on a sled is roll out back of plane.
After separation of sled, It fly then remote-controlled from the second plane
end of glide fly, its unfolded a parachute and landing in water
First droptest over the North Sea, then fall 1971 south at island of Sardinia
Further droptest made in 1973.
(the Foto with LB21 under wing of C-130. like a x-15, are new to me )
Boomerang and the sleds were recovered from employed local Fisherman.
Under the supervision of staff ERNO
Phase III
Start of unmanned LB 21 with Europe II rocket
An singel orbital flight
With a 600 kiloPond heavy Model (stand so in the magazine!)
Unfortunately LB 21 Bomerang program end after Phase II
Because in 1974 ELDO-ESRO dissolved and ESA was founded.
All EUROPE II flights were canceled and development of the Ariane 1 began ...
Note
ERNO = Entwicklungsring Nord = Northern development circle
was a 1961 joint venture of Bremen-based Weserflug and Focke-Wulf with Hamburger Flugzeugbau.
to develop parts for rockets and get involved in space activities.
later they work with Bolkow on EUROPA 1 & 2 ROCKET, Third Stage ASTRIS.
Phase II model hangs in Deutsches Museum in Munich, Germany
The full name of the museum in English is The German Museum of Masterpieces of Science and Technology (German: Deutsches Museum von Meisterwerken der Naturwissenschaft und Technik). tipcal german ;D
they got a big spaceflight archives with 12,000 folders with photographs, technical descriptions, manuals, newspaper and magazine articles, research reports, gray literature. also over LB 21 Bomerang data.

unfortunate the museum refuse the Use of (in museum) taken Fotos in Internet. And also to sell them.
Dam....
wat got the Peenemünde museum on LB 21 Bomerang ?
