Abstract
Hollow inlet guide vanes in the air intake of a gas turbine engine are supplied with pressurized bleed air. The interior of the vanes are provided with orifices through which the bleed air must flow, and those orifices are tuned to a desired frequency which sets up vane vibrations. This arrangement provides deicing by both the supply of heated bleed air which impinges on the selected areas of the vanes and by the vibrations which are set up in the vanes, and it does so simply with the use of the bleed air.
