Abstract:

Flow through the pumps on a 115th scale model of the X-Craft, Model 5612, was measured. An external, strut-mounted, three-component LDV system was used to measure the flow ahead of the pump inlet, and an internal, three-component LDV system was used to measure the flow ahead of the rotor and inside the nozzle of the waterjet. These tests revealed the flow structure within the pump, and allowed the calculation of terms required for an analysis of the pump performance. The pump was tested at two underway speeds corresponding to 25 and 40 knots full scale and at two bollard conditions.
