<p>The inlet (2) has a controlled filtration system (10) with a foldable filtering unit (11) i.e. plane filter, that is arranged at the level of an inlet section (3) of an air flow path. The system has a control unit (13) which exerts the effort along a transverse direction (Y) on a free end (11') of the unit (11) for compressing or expanding the unit (11) to vary dimension of the unit (11) to adjust the filtration power of the system. A guiding unit (12) has external and internal grids (12', 12'') for guiding the system to guide the displacement of the free end induced by the control unit. An independent claim is also included for a method for filtering the air in a turboshaft engine of an aircraft.</p> |
