Abstract
A turbine engine is provided that includes a fan section, a nose cone, a compressor inlet, a fan duct, and a particle separation system. The fan section has a plurality of fan blades disposed around a circumference of the fan section. The nose cone is disposed forward of the fan section. The compressor inlet is disposed aft of the fan section. The fan duct is disposed radially outside of the compressor inlet. The particle separation system is configured to produce an electrostatic charge on one or more surfaces forward of or adjacent to the compressor inlet. The electrostatic charge is configured to cause charged particles present within an air flow entering the engine to divert from the compressor inlet and enter the fan duct.
Claims19
A turbine engine, comprising:
- a fan section (FS) having a plurality of fan blades disposed around a circumference of the FS;
- a nose cone disposed forward of the FS;
- a compressor inlet disposed aft of the FS;
- a fan duct disposed radially outside of the compressor inlet;
- and
- a particle separation system configured to produce a first electrostatic charge on continuous surfaces of the nose cone and the FS, extending to an inner radial boundary of the compressor inlet, and configured to produce a second electrostatic charge on one or more surfaces proximate to an outer radial boundary of the compressor inlet;
- wherein the second electrostatic charge is opposite the first electrostatic charge;
- and
- wherein the first electrostatic charge and the second electrostatic charge are configured to cause charged particles present within an air flow entering the engine to divert from the compressor inlet and enter the fan duct.
A method of separating particles entrained within an air flow entering a turbine engine, the turbine engine including a fan section (FS) having a plurality of fan blades, a nose cone disposed forward of the FS a compressor inlet disposed aft of the FS and a fan duct disposed radially outside of the compressor inlet, the method comprising:
- producing a first electrostatic charge on continuous surfaces of the nose cone and the FS, extending to an inner radial boundary of the compressor inlet;
- and
- producing a second electrostatic charge on one or more surfaces proximate to an outer radial boundary of the compressor inlet, wherein the second electrostatic charge is opposite the first electrostatic charge;
- wherein the first electrostatic charge and the second electrostatic charge are configured to cause charged particles present within an air flow entering the engine to divert from the compressor inlet and enter the fan duct.
