1. The TS starter unit was to be installed ii the Jumo-012 with its exhaust unit
pointing upstream to the air intake flow. The Soviets at Experimental Plant
No. 2 in Upravlencheskiy (53-12N-N50--09E-) objected to this type of mounting
,because of the undesirable preheating of the intake-air for the first
compression stage, which would be effected. by the exhaust gases of the
starter unit. According to source,, the Soviet objections were justified to
a certain degree by the ratio of hot exhaust gases of the starter engine
to intake-air of the main power plant, i.e., 1.3 kg/sec gases with a tempera-
ture of 6500 C to 15 kg/rec intake-air. Experiments, however, revealed
the preheating o' intake-air to be of no harm during the fummer and even
advantageous during the triiter. As a precautionary measure it was planned
to install shutters, similar to Venetian blinds, in the c;#. .g of the intake
cone. These shutters wft-e to close the-intake and the exha+i$t apertures
of- the starter engine as soon as the ma iii engine had started
2. The contents of six letters source received from Engineer Guetter, (fnu), indt
cated that in late 1950 the starter expert team was engaged in the develop-
ment of a 100 hp turbo starter engine.. Source stated that the use of high
quality materials ,nd not structural alterations would-be required to achieve
the increased power. The original TS starter engine had 77 hp and was designed
with a compressor running at 41,350 rpm.. Because of difficulties with the
ball bearings, the speed was reduced to 379500 rpm., still sufficient oven
for the Jumo engines 012 and 022,whi.ch required a maximum of 65 hps for
starting*3

0 Comment: It.is doubted that 65 hp is sufficient to start these engines.
The shutters cadre a loss of power, and in winter great resistances eve to be
overcome during; the starting operation.. For these reasons surplus poker of the
starter engine -.s required,which explains the Soviet request for construction
of amore powerful starter. J'uto 012 engines were reportedly not in mass pro?
duction, ;s Soviet requirements of this class of engine allegedly were met by
Soviet-built Nene engines, However, information receive& indicates that the
Soviets it to terminate the construction of the Jumo 012.
