Abstract
Sand and dust erosion of turbine engines by ingested particulate matter is 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.
