A variable geometry inlet system of an aircraft engine includes an inlet duct. The inlet duct includes at least first and second sections moveable between extended and retracted positions such that the inlet duct defines a variable axial length of an inlet in controlling noise.


1. A variable geometry inlet system of an aeroengine comprising an inlet duct having an annular lip portion and a front opening defined by the annular lip portion for intake of an air flow, the inlet duct configured for directing the air flow from the front opening to a compressor, the inlet duct including at least first and second sections, the first and the second sections movable relative to one another between an extended position and a retracted position, the first and second sections in the extended position defining an axially longer inlet duct th...
