Foreign Object Ingestion Prediction for Engine Inlets by Trajectory Analysis in a Potential Flow Field

摘要

PX7GRA;An investigation was made of the application of a water droplet trajectory computer program to the prediction of foreign object ingestion of engine inlets. Variations of particle size, weight and initial conditions on particle trajectories were investigated for a stationary and a moving engine inlet potential flow field. A surface-particle resilience factor used with an added solid particle ricochet routine was also evaluated. The computed results provide an adequate solution for plane flow fields or the vertical centerline plane of an axially-symmetric flow field. (Author)
