Largest Ff Waterjet Seen For The First Time At Seawork Exhibition

摘要

Rolls-Royce introduced the largest waterjet to appear thus far in its Kamewa FF series at Seawork 2007 in Southampton last month. The FF600 unit extends the power range of the axial flow waterjets to l,800kW.rnIn common with the other units at the smaller end of the Rolls-Royce waterjet range, the FF600 is constructed in aluminium, with the impeller, its housing, shafts and the operating cylinders for steering and reversing made of stainless steel. The inlet duct is fabricated from aluminium sheet to an optimised hydrodynamic profile and the mounting flanges are supplied in two versions, one for welding direct into an aluminium hull and the other for bolting into hulls made of other materials.
