The long-range migration of monarch butterflies, extended over 4000 km, is not well understood. Monarchs experience varying density conditions during migration, ranging as high as 3000 m, where the air density is much lower than at sea level. In this

This paper describes an experimental study on inlet distortion in the flow ingested to an intake of a ducted fan. Recent high bypass ratio engines tend to shorten the nacelle length for better fuel consumption. In return, the shorter the nacelle inta
