Performance of Gas-Augmented Waterjet Propulsion System.

Abstract

The report describes an investigation of the performance of a gas-augmented waterjet propulsion system. The study was divided into three parts. First, an analytical investigation was conducted to determine the performance of air-augmented waterjet thrust nozzles. Also, comparisons were made between equations from the literature for the local sonic velocity and the sonic velocity predicted by the analysis. An experimental investigation was performed to determine the validity of the model development in the first part. The agreement between analysis and experiment was good for low air-water ratios. The third part of the report describes a study used to estimate the overall performance of a gas-augmented propulsion system. Several parameters were varied to determine their effect upon the performance. (Author)
