    • A device for stabilizing yaw motion is provided for use on a helicopter having a main rotor rotatable about a main rotor axis, a power source, and a tail rotor boom with a longitudinal axis. The device includes a tail rotor and a gyroscopic mechanism. The tail rotor is mounted to the tail boom of a helicopter and is rotated about a tail rotor axis by the power source to generate a thrust force transverse to the tail boom and offset from the main rotor axis. The gyroscopic mechanism automatically varies the thrust force generated by the tail rotor to oppose yaw motions. The gyroscopic mechanism includes first and second variable pitch gyro arms extending along first and second gyro arm pitch axes, respectively, a support mechanism, and a pitch adjustor linkage. The support mechanism is configured to support the variable pitch gyro arms for pivotable movement about a gyro pivot axis between a nominal orientation and a tilted orientation so that the variable pitch gyro arms pivot about the gyro pivot axis from the nominal orientation toward the tilted orientation in response to yaw motion encountered by the gyro arms during flight to vary the thrust generated by the tail rotor. The pitch adjustor linkage is appended to the first gyro arm to adjust the pitch of the first gyro arm about the first gyro arm pitch axis.
    • 提供一种用于稳定偏转运动的装置,用于具有可绕主转子轴线旋转的主转子的直升机,具有纵向轴线的动力源和尾转子悬臂。 该装置包括尾部转子和陀螺仪机构。 尾部转子安装在直升机的尾臂上,并通过动力源围绕尾部转子轴线旋转,以产生横向于尾臂的推力并从主转子轴线偏移。 陀螺仪机构自动地改变由尾部转子产生的反作用力与偏航运动的反作用力。 陀螺仪机构包括分别沿着第一和第二陀螺仪俯仰轴延伸的第一和第二可变俯仰陀螺臂,支撑机构和俯仰调节器连杆。 支撑机构被配置为支撑可变俯仰陀螺臂,用于在标称方向和倾斜方向之间围绕陀螺仪枢转轴线的可枢转运动,使得可变俯仰陀螺臂围绕陀螺仪枢转轴线从标称方位向倾斜方向枢转 响应于在飞行期间由陀螺仪臂遇到的偏航运动,以改变由尾部转子产生的推力。 俯仰调节器联动装置附加到第一陀螺仪臂以调整第一陀螺仪臂围绕第一陀螺仪俯仰轴的俯仰。
