Abstract
Inertial particle separators having an axially translating or a deformable poppet component are described. The poppet component axially translates to accommodate a wide range of flowrates through the inertial particle separator. In some arrangements, the poppet component is biased by a spring towards a closed or restricted position. The variable flowrate and constriction provided by the poppet maintains a substantially constant pressure drop and separation efficiency during operation across a wide range of flowrates through the separators.
