摘要： A drive system is provided between a ram air turbine (10) and at least a pair of accessory power units (38,40) of an aircraft, the ram air turbine being movable between stowed and deployed positions relative to the fuselage of the aircraft. The problems of providing a compact lightweight design which eliminates extraneous components in the airstream and a system which operates at optimum speeds are solved by the use of a drive shaft (28) extending between the ram air turbine and a first accessory power unit (38), such as a hydraulic pump, within the aircraft fuselage. First gears (30, 34) rotatably couple an outer end of the main drive shaft to the ram air turbine. Second gears (36,48) rotatably couple an inner end of the main drive shaft to the first accessory power unit. Third gears, in the form of a gear train (54), rotatably couple the first accessory power unit to a second accessory power unit (40), such as an electrical generator, within the aircraft fuselage. The pair of accessory power units have generally parallel drive shafts (44,52) rotatably coupled by the gear train.
