A turbine engine construction comprises an accessory drive mechanism in which accessories are mounted circumferentially around the turbine casing. The engine includes a planetary gear mechanism driven by a shaft extending axially outward from compressor and turbine sections of the engine, and forwardly of the air intake in the turbine casing. Accessory drive assembly includes a planetary gear mechanism having a ring gear exposed through circumferentially spaced apertures in the turbine casing to driven gears extending outwardly from accessory housings secured to the periphery of the turbine casing.

Accessory drive for a turbine engine

A torque measuring device is provided for measuring the engine torque of an engine having an output shaft and connecting through a gear box having a planetary gear arrangement to a load. The torque measuring device comprises a hub having an axis and supporting the stationary member of the planetary gear arrangement coaxial with the axis of the hub. An annulus is secured to and supports the gear box housing and is also secured to the hub by a plurality of circumferentially spaced spokes extending between the annulus and the hub and tangent to some circle coaxial to the hub. As the torque applied to the planetary gear arrangement increases, the hub rotates from its at rest position deflecting the spokes in proportion to the reaction torque of the stationary members. An arm extending outwardly from the hub cooperates with a position transducer to measure the amount of rotation of the hub with respect to the annulus and thus the torque on the planetary gear arrangement.
