초록

A turbine engine inlet system includes a curved duct 14 to deliver air to the engine, an inlet lip 16 to smooth the entry of air flowing into the duct, a forward inlet section 18 submerged within the aircraft skin contour to provide a degree of ram recovery to the duct, and a movable air deflector 20 which is flush with the forward inlet section 18 during normal flight conditions and extended to slightly above the inlet lip 16 during icing conditions.

청구항

An aircraft turbine engine inlet for an aircraft having a skin contour, comprising: a duct for directing air to the aircraft engine having a face which protrudes above the aircraft skin contour and having at least one bend for preventing direct line of sight to the aircraft engine, said face having a top edge and a bottom edge; an inlet lip formed in the aircraft surface over said top edge of said face having a rounded leading edge for preventing air turbulence in said duct; and a forward section in the aircraft skin forward of and adjacent to said botto...
