The research goal for this project is to better understand the interaction of a fan and UAV during an ingestion scenario. The objectives of this research are to: (i) create a generic high bypass ratio fan model that has features that are representative of a fan in a modern engine typically found on a large commercial transport; (ii) develop a component and full scale validated model of a quadcopter UAV (initially validated critical components in the first phase of the airborne collision research at different conditions) at the conditions of the ingestion event; and (iii) simulate various ingestion events to understand the sensitivity of a collision to various parameters of the ingestion.
