Marine Propellers - MIT

Hydrodynamics Reading #10 version updated 8/30/2005 -1- 2005 A. Techet Hydrodynamics Prof. Techet Marine Propellers Today, conventional Marine Propellers remain the standard propulsion mechanism for surface ships and underwater vehicles. Modifications of basic propeller geometries into water jet propulsors and alternate style thrusters on underwater vehicles has not significantly changed how we determine and analyze propeller performance. We still need Propellers to generate adequate thrust to propel a vessel at some design speed with some care taken in ensuring some reasonable propulsive efficiency.

2.016 Hydrodynamics Reading #10 version 3.0 updated 8/30/2005-4- ©2005 A. Techet Blade Root and Blade Tip The root of a propeller blade is where the blade attaches to the hub. The tip is the outermost edge of the blade at a point furthest from the propeller

2-D inviscid flow the pressures on forward and aft surfaces balance so that no drag is produced, the effect of the boundary layer leads to an imperfect canceling of these pressures so some additional drag is created. Inviscid or vortex drag is produced by the trailing vortex wake of a three-dimensional lifting system.

Equations of Surfaces In two dimensions, the solution set of a single equation involving the coordinates x and/or y is a curve. In three dimensions, the solution set of an equation involving x, y and/or z is a surface. Example The equation z = 3 describes a plane that is parallel to the xy-plane, and is 3 units
