DEFINITION OF THE DUST ENVIRONMENT FOR PURPOSES OF GAS TURBINE INGESTION STUDIES. PHASE 1

The purpose of this study is to define the dust environment which a gas turbine engine would experience when operating in a dusty terrain or near equipment causing dust to be airborne. A literature review and supplemental data acquired under various dust conditions were used to establish the severity, duration, and other important factors of dust concentration. Features associated with the dust environment are discussed and the limitations of physical measurements are presented. Summarized results are given with dust concentration within prescribed ranges.
