抄録（英）
Forced oscillation wind tunnel tests were conducted on a delta wing model with a 60 deg swept leading edge using JAXA's 60 cm high angle of attack (AOA) magnetic suspension and balance system (MSBS) wind tunnel. The pitch axis dynamic derivatives of the model were measured, and the effects of the center AOA of oscillation, oscillation amplitude, and oscillation frequency were surveyed. The loci of the aerodynamic longitudinal components varied complexly according to oscillation center AOA, amplitude, and frequency; however, in cases of oscillation center AOA of 0 degree and frequency of 1 Hz, the loci of pitching moment tended to vary in similar form with increase of the oscillation amplitude. The degree of scatter of the dynamic derivatives tended to be larger at higher angles of attack.
