Improvement of high-speed craft propulsion by using of propellers with shifted blade connection on the hub

The description of the variable pitch propeller (VPP) is presented. An insight into this propeller operation is given. It's advantages which give the improvement of propulsion of different purpose ship in comparison with the traditional propeller are noted. To be said in the report it is confirmed by example.

Improvement of High Speed Craft Propuls

 

In the course of VPP design as applied to sea-going ship and to trawler it was widely utilized the program product FlowVision which able to define hydrodynamics characteristics of VPP. The FlowVision is dedicated to flow simulation at high Reynolds number and small changed density. About other settings in FlowVision of VPP you can find in this article.
