05 - PropulsionAERODYNAMIC AND AEROACOUSTIC INVESTIGATION OF SWIRL RECOVERY VANES FOR PROPELLER PROPULSION SYSTEMSL.E. van den Ende¹, Q. Li¹, F. Avallone¹, D. Casalino¹, G. Eitelberg¹, L.L.M. Veldhuis¹; ¹Delft University of Technology, Netherlands Investigations has been made of integrating the propeller and aircraft for better installed efficiency resulting from the swirl recovery from either the downstream wing or a set of swirl recovery vanes. Results has shown that by making use of the angular kinetic energy in the propeller slipstream, the propulsion efficiency has been improved. |
