ABSTRACT:
An extendable fairing for use between two aerodynamic surfaces (e.g., the engine nacelle and wing leading edge flap) of an aircraft is disclosed. The illustrated embodiment of the invention comprises a fixed fairing section, extending outwardly from an engine nacelle, and an extendable fairing section, housed within the fixed fairing section. During cruise, when the flaps are withdrawn, the extendable fairing section is withdrawn. During takeoff and landing, or other conditions when the leading edge flaps are extended, the extendable fairing section is extended and fills the gap between the fixed fairing section and the leading edge flap.
