Abstract
In this paper, the influences on aerodynamic performance of different leading-edge cross-section profiles of a 40 degree-sweep delta wing are investigated by force measurement in wind tunnel. It is shown that the lift of the delta wing with leeward beveled is the highest, and the lift of the delta wing with windward beveled is the lowest. It nearly has no influence for the wing beveled with different angles. The lift coefficient of the delta wing with leading-edge windward beveling at low angles of attack is a little higher than other delta wings.
