Abstract

A gas turbine engine (10) comprises a gearbox (28) comprises a sun gear (30), an annulus gear (32), a plurality of planet gears (34) and a carrier (36). The sun gear (30) meshes with the planet gears (34) and the planet gears (34) mesh with the annulus gear (32). The planet gear carrier (36) comprising a first ring (36A), a second ring (36B) spaced axially from the first ring (36A) and a plurality of circumferentially spaced axles (40) extending axially between the first ring (36A) and the second ring (36B). Each planet gear (34) is rotatably mounted on a respective one of the axles (40) and the axles (40) are arranged at a first radius (R 1 ). At least one of the first ring (36A) and the second ring (36B) comprises a metal matrix composite material ring (54A, 54B) and the metal matrix composite ring (54A, 54B) comprises a ring of reinforcing fibres (50) and the ring of reinforcing fibres having a second radius (R 2 ) greater than the first radius (R 1 ).
