Apparatus for controlling microwave reflecting

摘要

A microwave reflection control device of the present invention comprises a reflection member which divides the inside of an inlet duct of a gas turbine engine into a plurality of areas in a peripheral or radial direction with respect to a duct center axis. The reflection member is formed into a reflection curved surface shape to block and diffuse a microwave which comes toward a fan moving blade from the inlet duct. Thus, reflection of the microwave by the fan moving blade is suppressed.
