Electric power generating apparatus for use in aircraft

Abstract

An electric power generating apparatus for use in an aircraft includes: a manual transmission configured to change speed of rotational power of an aircraft engine 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. The manual transmission includes: a planetary gear mechanism; an input shaft connected to a carrier holding a planetary gear of the planetary gear mechanism; an output shaft connected to a sun gear of the planetary gear mechanism; a one-way clutch which is sandwiched between the input shaft and the output shaft and by which the rotational power of the input shaft is transmitted to the output shaft; and a brake connected to a ring gear of the planetary gear mechanism.
