Abstract:
A particle separator for use with a turbine engine to separate particles from air entering the turbine engine, the particle separator comprisingan air intake comprising an annular air intake passageway for conducting air into the turbine engine, the air intake passageway comprising an annular radially inner air intake passageway and an annular radially outer air intake passageway surrounding the inner air intake passageway, the air intake comprising an annular radially inner opening communicating with the inner air intake passageway and an annular radially outer opening communicating with the outer air intake passageway, the inner air intake passageway comprising a radially inner turn, the outer air intake passageway comprising a radially outer turn, an annular radially inner particle conduit comprising an annular radially inner particle passageway communicating with the inner air intake passageway through the inner opening, the inner air intake passageway being arranged to conduct a radially inner air flow through the inner turn such that inertia of inner particles entrained in the inner air flow tends to cause the inner particles to flow from the inner air intake passageway through the inner opening into the inner particle passageway to allow air from the inner air flow to enter the turbine engine without the inner particles, the inner particle conduit extending outside the air intake passageway as the inner particle conduit extends from the inner opening, and an annular radially outer particle conduit comprising an annular radially outer particle passageway communicating with the outer air intake passageway through the outer opening, the outer air intake passageway being arranged to conduct a radially outer air flow through the outer turn such that inertia of outer particles entrained in the outer air flow tends to cause the outer particles to flow from the outer air intake passageway through the outer opening into the outer particle passageway to allow air from the outer air flow to enter the turbine engine without the outer particles, the outer particle conduit extending outside the air intake passageway as the outer particle conduit extends from the outer opening.
