Abstract

The purpose of this study is to evaluate the accuracy of the dynamic stability derivative measurement for a winged model using a magnetic suspension and balance system (MSBS). The MSBS has an ability to evaluate the aerodynamic forces acting on a model by measuring the magnetic force without the support interference. To measure the dynamic stability derivatives of the winged model, the apparatus must be able to control the magnetic force acting on the model along all coordinate axes and to oscillate the model with the same waveform under wind-off and wind-on conditions. In this paper, dynamic stability derivatives are measured for the AGARD-B model by using a 0.1 m-MSBS after those performances are confirmed. Because we succeed in oscillating the AGARD-B model with the same sine curve waveform under both wind-off and wind-on conditions within the difference of 0.11°, the dynamic test results appear to agree with DATCOM data and the static test results.
