AbstractThe flow topological structures over two 65° swept delta wings (a flat plate TUD wing and an IAR delta wing) have been investigated at varies angles of attack, sideslip and roll angles. The observed skin - friction line pattern has been used to infer the topology of the flow on the wing surface. Special attention was paid to the flow on the nose, the boundary-layer transition and the topological evolution as the attitude (control parameter) changes. Two large-scale wind tunnel models of the apex were constructed to obtain more data on the flow in this region. A correlative studies between kinematical flow space and critical states in dynamic space was conducted which shows useful information for further studies.
