Abstract
A method and apparatus for separating particles from an inlet airflow of a turbine engine has a centerbody with at least one radially outward scavenge conduit. The inlet airflow has entrained particulate matter, which can impact an impact surface defining part of the centerbody. The particulate matter is radially diverted outward through at least one inlet to a scavenge conduit, unable to make a turn defined by the shape of the centerbody.
Claims24
A turbine engine comprising:
- an engine inlet having a centerbody and defining an inlet duct defining an inlet airflow path;
- an engine core arranged downstream of the centerbody and defining an engine centerline;
- and
- an inlet particle separator having at least first and second scavenge plenums with corresponding first and second plenum inlets to define corresponding first and second scavenge flow paths from the airflow path to the first and second scavenge plenums, where the first and second scavenge plenums are fluidly separated and arranged radially outwardly about at least a portion of the centerbody.
A method of separating particles from an inlet airflow of a turbine engine having a centerbody and defining an engine centerline, the method comprising:
- drawing a first scavenge airflow from the inlet airflow;
- drawing a second scavenge airflow from the inlet airflow at a different location than the first scavenge airflow, wherein the first and second scavenge airflows are fluidly isolated from each other.
An inlet particle separator for an engine having an inlet, the inlet particle separator comprising:
- first and second scavenge plenums arranged radially outward and extending circumferentially at least partially about the inlet;
- and
- first and second plenum inlets corresponding to the first and second plenums, wherein the first and second plenum inlets define corresponding first and second scavenge flow paths, which are fluidly separate.
