A parameter study was conducted to calculate the hub load transfer matrix (T-matrix) for each transient flight condition in order to reduce the hub vibration load through individual blade control (IBC) under transient flight conditions for a 5-blade tilt-prop rotor capable of tilt operation. First, the prop-rotor operating conditions for each transient flight condition were derived. For this purpose, a total of 9 maneuvering conditions were identified, and the tilt angle, forward flight speed, and prop rotor rotation speed for each condition were derived. Then, the parameters to be adjusted were selected using the IBC formula, and the hub load calculation results according to changes in each parameter were analyzed. In this case, the IBC operating frequency, amplitude, and phase angle were selected as parameters. Based on these results, an IBC parameter study was conducted for a total of 7 transient flight conditions, and the hub normal load for each condition was derived. The results of this study can be used to analyze the variation of the hub load according to the variation of the IBC input and generate a hub load transfer matrix for each transient flight condition. Additionally, active vibration control research will be conducted under UAM(urban air mobility) transient flight conditions using the generated hub load transfer matrix.
