Ice strike sheathing ring for the fan casing of an aircraft engine

摘要

The ring (4) has a segment (3) formed from fiber connection layers and comprising an inner wall (20) and an outer wall (21) that is connected to a fan housing in a fixed manner. Predetermined breaking points (7) running in a flow direction are arranged in the inner wall at a determined constant distance, where the distance is selected in such a manner so that pieces of the inner wall is formed during extreme ice strike pass outlet guide vanes that are connected to downstream of the fan.
