ABSTRACT:
A method of raising the propulsion efficiency of a propeller by reducing viscous drag. Basically, a fluid polymer solution is injected along the leading edge of the power face of the propeller blade to form a boundry layer solution adjacent the power face, thereby suppressing turbulence. A propeller suitable for practicing the above method is also disclosed.
