   Abstract

The permeable lifting profile (PLP) is a new concept in hydraulics and aerodynamics and is now submitted as a Patent application to the Romanian Patent Office. This profile has both very interesting hydraulic and mechanic properties. From the hydraulic point of view, this profile is increasing the lifting force and is stabilizing the surrounding flow, avoiding the boundary layer’s detachment. The sustaining arguments are based both on analyzing the birds wing and feather structure, result of millions of years of natural evolution and on using CFD modelling methods.

Key words:  Lifting profile, lifting force, boundary layer’s detachment.
