摘要： A partially luminous fan blade and fan containing same. The fan blade includes a light guide bracket, an annular sleeve, and a plurality of blades. The light guide bracket is formed with a shaft connection portion. The annular sleeve is integrated with the blades. The annular sleeve and the light guide bracket together form a hub portion of the fan blade. The annular sleeve is connected to the light guide bracket. The annular sleeve is provided with a light-shielding skirt. A bottom edge of the light-shielding skirt is lower than that of the light guide bracket.

摘要： A fan assembly for a gas turbine engine includes a fan duct, a fan, and an outlet guide vane assembly located in the fan duct axially downstream of the fan. The outlet guide vane assembly includes a first variable leading edge outlet guide vane that extends radially relative to the central axis and includes a leading edge portion and a fixed aft portion, the leading edge portion including a tip segment configured to rotate about a leading edge pitch axis and a hub segment located radially inward of and separate from the tip segment, the hub segment configured to independently rotate about the leading edge pitch axis relative to the tip segment. The assembly further includes two unique gear assemblies each configured to rotate one of the tip and hub segments.
