7. Changes have been made in the layout of Variant A of the 017; there are
four instead of two sets of bearings, so that turbine and compressor
have independent bearings (See Attachment).

withstand temperatures up to 10000 C. So far these blades have reached the
blueprint stage and tests are not to be anticipated before mid-1959. Series
manufacture of these blades will be undertaken by a firm in Immelborn,
Thuringia, believed to be called VEB Feinmetallwerk. The Immelborn firm
is currently engaged in preparing the jigs (Schablonen) and molds
(Gussformen) of the blades.

9. Testing of the compressor together with the gearing of the propellers showed
that vibration4l amplitude of the compressor increased with revolutions
and caused czeicking of the propellor gearing.
10. The first Versuchsobjekt of the 018 was placed on the test bed in October 1958,
but after a short time the Corpressor housing (Verdichtergehaeuse) sank 2 mm.
Soviet Engine
11. The Soviet engine, previously reported stripped in hall (Halle) 51 N at
Pirna, was subsequently re-assembled and transported to Dresden-Klotzsche.
The engine was definitely fitted with after-burning.. but temperature is not
known. The intake had a diameter of approximately 120 cms. and nothing
appeared to be unconventional about its form.
Organization
12. All the nationalized plants (VEBs) of the aircraft industry form part of the
VVB Luftfahrt-Industriebetriebe, the headquarters of which movedin early
October 1958 from Pirna to Dresden-Klotzsche. Alt Institute for Board
Instruments, an Electro-Technical Institute and an Institute for Research in
Basic Materials (Werkstoffkunde) are stilliocated in the Pi'rna complex and
are believed to be su94ordinate to the VVB.
13. The Chemnitz factory is still known as the VEB-Industriewerk Karl-Marx-Stadt.
It is hoped that these blades will
