Abstract：To study the supersonic flutter characteristics of the full-scale rudder-installed steering gear, a rudder model aeroelasticity test platform based on the FD-12 wind tunnel was designed by the China Academy of Aerospace Aerodynamics. The subcritical flutter test method was used to study the characteristics of the full-scale rudder installed in an actual steering gear. The rudder model was tested in a wind tunnel with a fixed Mach number of 1.5 and continuously raising the dynamic pressure. The flutter boundary was captured by three subcritical flutter boundary prediction methods: the Houbolt-Rainey method, the Peak-Hold method and the Zimmerman-Weissenburger method. The flutter boundaries were predicted using the rudder vibration response data measured by the accelerometers. The flutter dynamic pressure predicted by three subcritical flutter boundary prediction methods were respectively 0.070, 0.072 and 0.073 MPa, which were almost the same.
