AIRFOIL FOR A TURBOFAN ENGINE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17828112 titled 'AIRFOIL FOR A TURBOFAN ENGINE

Simplified Explanation

The abstract describes a patent application for an airfoil design.

The airfoil has a leading edge, a root end, a tip end, a leading edge end, and a trailing edge end.
The airfoil includes a body that extends from the root end to the tip end and is made up of multiple cavity walls.
These cavity walls create several cavities within the airfoil, each with an inlet located at the leading edge.
The innovation of this design is the addition of a porous face sheet that is placed on at least one of the inlets of the cavities.
The purpose of the porous face sheet is not explicitly stated in the abstract.

Original Abstract Submitted

An airfoil is provided defining a spanwise direction, a chordwise direction, a root end, a tip end, a leading edge end, and a trailing edge end. The airfoil includes: a leading edge extending from the leading edge end; a body extending along the spanwise direction between the root end and the tip end, the body including a plurality of cavity walls defining a plurality of cavities, each of the plurality of cavities having an inlet located at the leading edge; and a porous face sheet positioned on at least one inlet of the plurality of cavities.
