1. The Drl Gunther Lange E gineering Off ice (Cons truoti n
and precision tool shop) has been in opei etion for a year. Until
25x1 15 dune 1948 it was at 9-13 Trutsohierstraesse, Berlin-aohanniethei.
On this date it was moved to the Adlerahof to the premises of the
former DVL (Deutsche Versuchaanstalt fdr Luftfaahrt - German Aero-
nautical Research Institute). Dr. LANGE was formerly head of the
medium-sized wind-tunnel in the DVL.
2. The Dr. Gunther Lange Engineering uffioe is constructing the
following instruments and models for the Russian airforce;
a) a double-component scale for measuring the expansion and
resistance of streamlined objects.
b) a small air current generator
a) a small fog (or smoke) chamber to indicate eddies along sero-
naautical bodies
d) a six-component scale for measuring aeronautical bodies
fuselages, engine nacelles (Motorgondeln), wing surfaces (lift), etc.
e) a propellor-pull measuring instrument
f) a Mach-Number instrument which indicates the Meoh-Number without
conversion
g) plane models of V.S. and British plane types (B-29, Mosquito,eto. )
with service ceiling indications.
h) an instrument for the blind landing of planes (the locations
and ranges of the ground instruments are measured by means of a
colored wire; the various phases of blind landing such as flying
into the sounding beam, preparation for landing, actual landing,
rolling up to hanger, etc., are controlled by tone and light signals.)
I) a section of a 4-stage engine
3. The construction office is also producing the following instru-
ments in accordance with instructions from the Russian BTB office in
Adl ershof:
a) a wind tunnel with engine producing very cold air
b) as so-called "climatic chamber" for research on automobile
engines of the Yen and Tgtra type at a speed of 40 lamas per hour
and a temperature of -4? C. (see photo VI)
