Testing of a new design waterjet, the ONR Axial Flow Waterjet 2, was performed in the 36-Inch Variable Pressure Water Tunnel at the Naval Surface Warfare Center, Carderock Division. These tests measured the pump powering performance and the pump cavitation performance. The test hardware, methodology, and results are presented here, along with comparisons to computational predictions. The test results are used to make predictions of the performance of four 9-foot ...
