Abstract
A nacelle assembly for a turbine engine has a cowl. The cowl extends along an axis and has an exterior surface spaced from an interior surface. The interior surface forms an air inlet for directing airflow to the turbine engine. An opening is disposed on the cowl. A device for creating suction through the opening is in fluid communication with the opening. The opening removes a portion of a boundary layer flow through the cowl, thereby providing higher energy flow along the interior surface.

A nacelle assembly for a turbine engine, comprising:
- a cowl for a turbine engine, said cowl extending along an axis and having an exterior surface spaced from an interior surface, said interior surface forming an air inlet for directing air flow to the turbine engine;
- an opening disposed on said cowl;
- and
- a device for creating suction through said opening, said device for creating suction in fluid communication with said opening.
A turbine engine, comprising:
- a turbine engine extending along an axis;
- a fan cowl for a turbine engine, said fan cowl extending along an axis and having an exterior surface spaced from an interior surface, said interior surface forming an air inlet for directing air flow to the turbine engine;
- a core cowl extending at least partially about said turbine engine, said core cowl spaced from said fan cowl to form a bypass flow passage;
- an opening disposed on said interior surface;
- and
- a device for creating suction through said opening, said device for creating suction in fluid communication with said opening.
A method of controlling fluid flow along a nacelle surface, the method comprising the steps of:
- providing a nacelle surface having an interior surface and an exterior surface;
- disposing an opening on one of said interior surface and said exterior surface;
- and
- drawing air through said opening through a device that provides suction to said opening.
