DETERMINATION OF OPTIMUM OPERATION CONDITIONS FOR DIESEL ENGINES DRIVING CONTROLLABLE PITCH PROPELLERS

Soviet research and weather ships of the Passat series (length b.p. 86 m, 1000 dwt) are fitted and Sulzer medium-speed Diesel engines type 8TD48 (two engines per ship) driving a Liaaen S-80/90 controllable-pitch propeller. This article gives the results of trials in order to determine the optimum operating conditions for this combination of engines and propeller as installed in these ships. The results are given as graphs of fuel consumption against engine r.p.m., for various ship speeds and values of propeller pitch. A comparison is made between conditions with a clean hull, a hull with light fouling, and a hull with heavy fouling. A general graph is derived and recommended for use by the ships' command. It is stated that fuel economies of the order of 5--8% have been achieved in these ships following the recommendation. Order from BSRA as No. 51,435.
