PROTECTIVE MAT FOR LEADING EDGES OF AIRFOIL ELEMENTS

摘要

A device for protecting an airfoil element made of a complex comprising a polymer film, a metal strip deposited on a part of the polymer film and an adhesive element to attach the polymer film on the airfoil element. The polymer film forms a protection against sand abrasion. The metal strip forms a protection against water abrasion of the airfoil element on which the complex is attached.

1. Airfoil element protection device, comprising a complex comprising a polymer film, a metal strip deposited on a portion of the polymer film and an adhesive element to bond the polymer film to an airfoil element, the polymer film forms a protection against sand erosion and the metal strip forms a protection against water erosion of the airfoil element to which the airfoil element protection device is bonded thereto; wherein the complex is formed in counter-relief to fit a profile of a leading edge of the airfoil element comprising areas of low incidence and areas of high incidence, the polymer film is shaped to cover one or more areas of low incidence of the airfoil element, the metal strip is shaped to cover an area of high incidence of the airfoil element.
