Abstract

A gas turbine engine includes a fan rotor driven by a fan drive turbine about an axis through a gear reduction to reduce a speed of the fan rotor relative to a speed of the fan drive turbine. A fan case (108) surrounds the fan rotor, and a core engine with a compressor section, including a low pressure compressor. The fan rotor delivers air into a bypass duct defined between the fan case (108) and the core engine. A rigid connection (124) between the fan case (108) and the core engine includes a plurality of H-frame (116) connecting members rigidly connected to the fan case (108), and to the core engine. The H-frame (116) connecting members each are defined by two rigid legs (118) which extend between the fan case (108) and to the core engine, along directions which are generally parallel to each other. A plurality of non-structural fan exit guide vanes are provided with an acoustic feature to reduce noise and are rigidly mounted to at least one of the fan case (108) and the core engine.
