SHROUD DEVICE OF A JET ENGINE

摘要

A shroud device of a jet engine, including a radially internal shroud appliance and a radially external shroud appliance. The internal shroud appliance is embodied with a radially internal ring-shaped shroud part and a radially external ring-shaped shroud part. The internal shroud appliance includes multiple blades that extend substantially in the radial direction between the internal shroud part and the external shroud part. The radially external shroud appliance is embodied with a radially internal ring-shaped shroud part and a radially external ring-shaped shroud part. The external shroud appliance includes multiple blades that extend substantially in the radial direction between the internal shroud part and the external shroud part. The internal shroud appliance is embodied as a first one-piece cast structural component and the external shroud appliance is embodied as a second one-piece cast structural component.
