Comparison of UAS Ingestion Modeling With a Live Ingestion Test 

Foreign body ingestion into aircraft engines has been studied extensively for soft bodies such as birds and ice. Recently, there has been an interest in conducting research on the ingestion of hard bodies, like uncrewed aerial systems (UASs), into engines. These hard body ingestion studies have been growing in number and the fidelity of the models has increased as components and parts have been experimentally validated. Recent models include a UAS quadcopter model that has been experimentally validated at the conditions of an ingestion event and an open representative fan assembly model that was developed to capture the key structural features of a fan for foreign object ingestion studies. The purpose of this work is to experimentally validate the computational modeling approach of a UAS ingestion using a live ingestion of a UAS into a CFM56-7B engine. Details of the experiment and the data collected from the experiment are discussed. Comparisons of the kinematics, overall damage to the fan blades, strains at points on the blade, and out of plane displacement of the blades are used to validate the approach. Moreover, the CFM56-7B computational model is also compared with the open representative fan assembly model for a variety of cases to demonstrate the effectiveness of this representative model for future studies.
