| Abstract: |
| Based on the study of traditional single-rotor gyro rudder, this paper completes multi-disciplinary optimization design on amount, structure parameters, combination form and space distribution of rotors by simulation analysis and virtual experiments, and creates a series of multi-rotors combination gyro rudders which overcome the weakness of traditional single-rotor gyro rudder such as small control force and application range limit, thereby improve the control ability of aircraft roll stability. In addition, according to the constraints of some typical aircrafts, via the optimization design of gyro rudder combination, the damping factor of aircraft roll can be greater than 0.002, thus the aircraft can have fine roll stability which contributes to the application and innovation of gyro rudder combination in the field of tactics aircraft. |
