Abstract
A gas turbine engine includes an engine core includes at least one compressor, a combustor downstream of the compressor, and at least one turbine downstream of the combustor. A primary flowpath fluidly connects each of the compressor, the combustor, and the turbine. At least one particle extraction duct has an extraction duct inlet connected to the primary flowpath fore of the compressor and an extraction duct outlet connected to a bypass flowpath.

A gas turbine engine comprising:
- an engine core including at least one compressor, a combustor downstream of the compressor, and at least one turbine downstream of the combustor;
- a primary flowpath fluidly connecting each of the compressor, the combustor, and the turbine;
- and
- at least one particle extraction duct having an extraction duct inlet connected to said primary flowpath fore of said compressor and an extraction duct outlet connected to a bypass flowpath.

A method for removing debris from a gas turbine engine comprising:
- providing a particle extraction duct including an inlet connected to the fore of a compressor section and an outlet connected to a fan duct;
- passing debris from an expected debris path through said inlet and through said outlet;
- and
- expelling the debris out an aft end of the fan duct.
1 more element
A gas turbine engine comprising:
- a core including a primary flowpath, the primary flowpath having a steep radially inward turn upstream of a compressor inlet and downstream of a primary flowpath inlet;
- and
- a particle extraction duct connecting a radially outward surface of the primary flowpath to a fan duct, an inlet of the particle extraction duct being positioned at a base of the steep radially inward turn.
