Abstract
A ducted fan gas turbine engine includes a fan which is driven by a low pressure turbine via a load transmitting shaft. The load transmitting shaft additionally drives the accessories of the engine and the aircraft upon which it is mounted. In the event of an engine failure, the power produced by the windmilling of the engine fan is sufficient to provide continuity of drive to the accessories.
