Nacelle flow assembly

摘要

A nacelle assembly for a turbine engine has a cowl for a turbine engine. The cowl has a first surface spaced from a second surface. The second surface defines defining a bypass flow passage. A flow volume is spaced between the first surface and the second surface. A plurality of holes are disposed on the cowl. Each of the plurality of holes are configured to alter local air pressure about one of the first surface and the second surface of the cowl. The plurality of holes are in communication with the flow volume.

1. A nacelle assembly for a turbine engine, comprising:
a cowl for the turbine engine, said cowl extending along an axis wherein at least a portion of said cowl is axially forward of a fan of the turbine engine, said cowl having a first surface spaced from a second surface, said second surface configured to define a bypass flow passage radially inward of said second surface; a flow volume spaced between said first surface and said second surface; a plurality of holes disposed on said first surface and said second surface of the cowl and arranged to communicate air outside the nacelle assembly into said flow volume, each of said plurality of holes configured to alter local air pressure about one of said first surface and said second surface of said cowl, said plurality of holes in communication with said flow volume, and said plurality of holes extending between said flow volume and an exterior of the nacelle assembly; and a device in communication with said flow volume for altering local pressure at one of said first surface and said second surface, wherein said device is configured to increase local pressure.
