    摘要： An electric power generating apparatus for use in an aircraft is an electric power generating apparatus connected through an emergency cut-off device to a gear box such that the gear box can transmit power to the electric power generating apparatus, the gear box being configured to decrease speed of rotational power of an aircraft engine. The electric power generating apparatus includes: a manual transmission configured to change the speed of the rotational power transmitted from the emergency cut-off device and including a plurality of gear stages; and an electric power generator to which the rotational power which has been changed in speed by the manual transmission is transmitted.

    摘要： A gas turbine engine (20) includes a fan shaft (72)arranged along an engine central axis, a frame (78) supporting the fan shaft (72), a gear system (48) rotatably coupled with the fan shaft (72), and a flexible coupling (74) at least partially supporting the gear system (48). The flexible coupling (74) defines, with respect to the engine central axis (A), a torsional stiffness TS and a lateral stiffness LS such that a ratio of TS/LS is greater than or equal to about 2.0 to reduce loads on the gear system(48) from misalignment of the gear system (48) with respect to the engine central axis (A).

    摘要： An air turbine starter (10) for starting an engine (14), comprising a housing (30) defining an inlet (32), an outlet (34), and a flow path (36) extending between the inlet (32) and the outlet (34) for communicating a flow of gas there through. A turbine member (38) is journaled within the housing (30) and disposed within the flow path (36) for rotatably extracting mechanical power from the flow of gas and a gear train (40) is drivingly coupled with the turbine member (38). A drive shaft (64) is operably coupled with the gear train (40), and a decoupler (70) is selectively coupled to the drive shaft (64) for decoupling the air turbine starter (10) from the engine (14).
