Hydrodynamic Design Principles of Pumps and Ducting for Waterjet Propulsion
Abstract
The purpose of the report on the special form of hydrodynamic propulsion known as waterjet propulsion is to make the viewpoint of a pump designer known to the developers of waterjet devices. More specifically, it is concerned with the contribution that the pump designer can make in order to give the designer of the entire propulsion plant the greatest possible freedom to find and use the most favorable overall arrangement. There is no attempt to cover the entire field of waterjet propulsion. Moreover, only aspects of preliminary design are considered because it is in this stage of development that irreparable mistakes can be made. Following an outline of the principal problems involved in the propulsion of high-speed surface craft, the design principles of hydrodynamic (centrifugal and axial flow) pumps are described and later applied to the design of waterjet propulsion pumps. The intake and duct problem is then described and designs are illustrated for a few typical overall arrangements.
