What is it about?

Small Unmanned Aerial Vehicles fly in highly unsteady flows, and so may suffer from flow separation. Literature suggests a constant parameter, based on how much suction can be supported by the leading edge, is a viable means of predicting such separation. This paper examines whether such a constant value applies to highly-irregular turbulent flows.

Why is it important?

Predicating flow separation is critical to the performance and safe operation of small UAVs. This paper examines the variability of the leading edge suction in flows replicating those seen by a small UAV in operation.
