Abstract
This paper was first published in the M.A.N. Forschungsheft No. 6/1956. We consider, however, that information on the new M.A.N. radial type high-pressure supercharger is of sufficient interest to shipbuilders, shipowners and others who may not be readers of the Forschungshefte to warrant a reprint in the M.A.N. Diesel Engine News.
No. 30/1954 of the Diesel Engine News covered the design features of high-pressure superchargers originally used in conjunction with M.A.N. 4-stroke diesel engines of the K6V45/66 m.H.A. type. This unit was comprised of a 3-stage axial type reaction turbine and a 14-stage axial flow compressor. The axial type had been chosen because our axial compressors at that time were more advanced from the viewpoint of efficiency than were radial compressors. In the meantime the radial compressor has caught up and is, therefore, preferably used in new power-plant designs. The present article deals with the new M.A.N. high-pressure supercharger of the radial type installed in the m.s. Tannstein and her sister ship Torstein.
