1. An inertial particle separator comprising:
a housing defining a central compartment, the housing comprising an inlet and a dust port;
an inner body coupled to the housing, the inner body comprising a central tube having a first end extending into the central compartment and a second end defining an outlet; and
a poppet positioned adjacent to the first end of the central tube, the poppet movable or deformable between a closed position, in which the first end is blocked, and an open position, in which the first end is at least partially unblocked, the poppet being biased to the closed position.
