Developing a magnetic suspension system capable of large-amplitude dynamic stability test of aircraft over wide range of angle of attack

Magnetic suspension and balance system (MSBS) suspends a model without physical support systems. The 60 cm MSBS that can suspend a model over an angle of attack range from-40 degrees to 40 degrees (60 cm high-AOA MSBS) was successfully developed. A new position sensing algorithm that dynamically changes the scanning line according to the attitude of the model was developed and installed to an existing 60 cm MSBS at JAXA. Static and dynamic wind tunnel tests were conducted to investigate the ability of the MSBS and the dynamic characteristics of a delta wing aircraft model at various angle of attacks (AOAs). The MSBS could suspend and oscillate the model in pitch direction at AOA of 15 degrees with the amplitude of 6 degrees in the wind.
