    摘要： The present invention provides a mechanical arrangement for an engine (10) having two propeller stages (23, 24), comprising: a first epicyclic gear (72) stage comprising a sun gear (60), a planet gear (62), a planet carrier (64) and an annulus (68), wherein the sun gear (60) is driven by a shaft (26) of the engine (10), the planet carrier (64) is stationary and thereby permits static structure (66) to be located therethrough, and the annulus (68) outputs torque and/or drive,- a second epicyclic gear stage (58) comprising a second sun gear (28'), a second planet gear (32), a second planet carrier (34') and a second annulus (38), wherein the second sun gear (28') is driven by the annulus (68) of the first epicyclic gear stage (72) and is annular to accommodate the static structure (66), the second planet carrier (34) comprises the output (36) to one of the propeller stages (23) and the second annulus (38) comprises the output (40) to the other of the propeller stages (24); wherein the static structure (66) provides mounting for static components on one or both sides of each epicyclic gear stage (58, 72).
