초록

A laminar flow nacelle for an aircraft engine (10) has an outer member (26) defining an aerodynamic shape. The nacelle (24) has an inner member (28) defining a chamber (30) with the outer member (26) of the nacelle (24). The outer member (26) of the nacelle (24) has a porous region (32) at a first region (34) of the outer member ( 26) and the porous region (32) allows a flow of fluid into the chamber (30). A duct (36) connects the chamber (30) to an aperture (38) in the outer member (26) at a second region (40) of the outer member (26) downstream of the...
