Abstract
A drum compressor rotor (10) for use in a gas turbine engine comprises a plurality of high strength, low density filaments (18a-d) which are covered with a high temperature adhesive resin and tightly wound around the hub (12) between rows of fan blades (14). The filaments allow an increase in the maximum compressor rotor operating speed thereby increasing the potential performance of the turbine engine. The filament windings (18a-d) are significantly lighter and less expensive than conventional welded metal support disks (106a-c).
