Subject of the present paper are force and pressure measurements performed on a sharp-edged cropped delta wing with 65° leading-edge sweep. Motivation for the tests were the provision of experimental data for validation of unsteady computational codes and understanding of the flow past an oscillating delta wing. The tests were conducted in the Low-Speed Wind Tunnel (NWB) of DNW and included static measurements as well as dynamic measurements with the model oscillating in pitch .. Results of the balance measurements are presented for different sting configurations in static case and for various mean angles of attack in dynamic case. Results of the pressure measurements are presented for static angles of attack and for pitching oscillations about the mean angles of attack
