Abstract
A fan duct assembly includes a bypass duct, an outlet guide vane assembly, and a flow control system. The bypass duct has an outer wall and an inner wall that define a gas path for bypass air therebetween. The outlet guide vane assembly is coupled with the bypass duct and includes a plurality of vanes. The flow control system is configured to direct selectively a portion of the bypass air flowing through the gas path radially into each of the plurality of vanes.
