Sand and dust erosion of turbine engines by ingested particulate matter is a major problem facing both airframe and engine manufacturers. Various types of particle separators are used to keep sand and dust out of the engine. In these separators the particles are diverted by swirl vanes and similar devices to keep them out of the engine. An inlet scroll separator herein permits the particles to continue their course of travel and diverts the air stream, reducing power requirements and eliminating swirl and deswirl vanes.


In a gas turbine engine particle separator of the scroll type, in combination, a first inertial particle separator for coarse particle removal, and a second inertial particle separator in series therewith for the removal of fine particles, the first inertial separator comprising an air inflow pipe, a curved section to said pipe adapted to effect an initial centrifugal gradient of particulate matter in inlet air, and a collection chamber disposed on the outside of the curved section of said inflow pipe to trap coarse particles centrifuged therein, particl...
