In one embodiment, a gas turbine engine may include an accessory system integrated in a frame between a bypass flow path and a core flow path. A shaft may be provided between the accessory system and a core shaft of the gas turbine engine. The integrated accessory system may include power devices such as motors and generators, among other types of devices. The gas turbine engine may have more than one device spaced at various circumferential locations. In one non-limiting example, two power devices may be spaced 180 degrees apart. In some embodiments, a ...


1. An apparatus comprising: a gas turbine engine having a shaft operable to transmit mechanical power;a first flow path disposed internal to the gas turbine engine and defined by an inner first flow path wall and an outer first flow path wall;a second flow path disposed radially inward of the first flow path in the gas turbine engine and defined by an inner second flow path wall and an outer second flow path wall;a gearing operably coupled to the shaft and disposed between the first flow path and the second flow path wherein the gearing is operable to in...
