It is a well known fact that both mechanical and thermal stresses increase in those engine components which serve to transmit a certain output at decreasing circumferential speeds of the driving parts. Mechanically, reduced revolutions cause the dynamic forces to decrease with the square and, in turn, result in an increase of the load on the bearings. Thermally, low engine speeds result in insufficient gas flow driving the turbo-blowers which thus become unable to build up the required scavenge air pressure for a proper combustion process in the cylinders of a supercharged diesel engine. This paper aims at a better understanding of the mutual requirements when designing merchant ship propellers.
