EXPERIMENTS WITH A STEAM-TO-WATER PSEUDO-BLADE PROPULSOR FOR MARINE APPLICATION. PART I. TECHNICAL DISCUSSION.
GRUMMAN AIRCRAFT ENGINEERING CORP BETHPAGE NY RESEARCH DEPT
An experimental model of a device suitable for propelling torpedoes was tested in a water tunnel over a speed range of 0 to 30 fps. This device, called the pseudo-blade propulsor, is based on the concept of direct energy transfer between two fluids utilizing moving pressure fields. The model used steam as the primary, high energy fluid and water as the secondary or low energy fluid. The test results prove that the concept is sound and shows promise for application as a propulsor for torpedoes and other water borne vehicles. Two illustrations of the basic concept are included in the report to demonstrate the mechanism involved in the transfer of energy. Author
