Abstract
A method of manufacturing an aerofoil for a gas turbine engine (). The method comprises the steps of providing first and second panels (), providing a web () between the first and second panels, deforming the panels by applying internal pressure between the panels so as to form an internal cavity. The method further includes the step of providing a pattern of ribs () on the web so as to define a aerofoil having first and second panels with at least one rib () forming a protrusion extending from the first panel partially across the space between the first and second panels.
