Wind tunnel data, obtained in the framework of a cooperative U.S. - Dutch program of research are presented and discussed. This Unsteady Transonic Delta Program (UTDP) focuses on two closely related areas: Limit Cycle Oscillations (LCO) on a realistic fighter configuration and unsteady transonic flows about a simple strake (SiS) delta wing. LCO is limited amplitude self-sustaining oscillation produced by a structural/aerodynamic interaction and is generally occurring at (heavy) loaded fighter type wings at transonic speeds; shock induced and trailing edge separation play a dominant role in its development. In this paper flows with phenomena, characteristics for LCO, are analyzed.
