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 1. oanenta For details of the insta 4ation of the TS starter engine in ur o et power plants, see Attachment, Sketch 1. .CLASSIFICATION SECRET 25X1 Approved For Release 2c 16 I0l : CIA-RDP82-00457R0114b0100004-4 Approved For Release 2003/08/06: CIA-RDP82-00457R011400100004-4 25X1 SECRET 25X1 25X1 2.

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.
