摘要： A gas turbine engine rotor disc is presented. The rotor disc includes a hub, a web, a blade retention arrangement, a rotational axis, a first axial side and a second axial side. The hub has a central bore around the rotational axis. The web is integrally formed with and extends radially outwards from the hub to the blade retention arrangement. The blade retention arrangement has a centre of mass. A radial plane perpendicular to the rotational axis passes through the centre of mass. The first axial side is for engaging a tension bolt. The radial plane intersects the hub defining a first axial side portion towards the first axial side and a second axial side portion towards the second axial side. The second axial side portion has an axial extent which is between 10% and 30% greater than an axial extent of the first axial side portion.

The gas turbine section includes an inner and an outer gas path walls that are concentrically arranged about an axis and adapted to form together at least a part of the annular gas path defined through the gas turbine engine. The gas turbine section includes at least one strut extending generally radially relative to the axis from the inner to the outer gas path walls. The strut has a leading edge, adapted to be positioned upstream relative to the annular gas path, and a trailing edge, adapted to be positioned downstream relative to the annular gas path.
