NACELLE ASSEMBLY OF GAS TURBINE ENGINE, AND SYSTEM AND METHOD FOR CONTROLLING AIR FLOW PASSING THROUGH AIR INTAKE OPENING THEREOF

摘要

PROBLEM TO BE SOLVED: To prevent separation in air flow by adding air flow into an intake opening 16 of a nacelle in response to operating conditions. SOLUTION: Air flow 14 flows along an outside surface 20 and inside surface 22. During operation when it is desirable to stabilize air flow along the inside surface 22 by adding air flow, an inlet flow control system supplies air to an intake opening 16 from the rear of an outlet guide vane 42, and include an intake passage 24 integrally formed therewith in the rear of the outlet guide vane 42 in an intake fan 34. The intake passage 24 supplies air to a plurality of separated passages 26, which lead the air to a plenum 30. Each of flow outlets 32 includes a flow control device for controlling air flow flowing out of the plenum 30. Additional air flow 36 from the plenum 30 controls air flowing inside a nacelle 12.
