## 7.21.11 Aerodynamic outputs
In this section the outputs of the aerodynamics module are explained. To understand the outputs, the definitions of the rotor axial/tangential direction are defined in the figures below. Note that “axial” indicates in direction of normal vector “n” and tangential indicates in the direction of tangent vector “t”. Further note that the radial vector “r” assumes an un-coned rotor.
本节解释气动模块的输出结果。为了理解这些输出,请参考下方的图示,其中定义了风轮轴向/切向方向。请注意“轴向”表示法向量“n”的方向“切向”表示切线向量“t”的方向。此外径向向量“r”假设为无锥度风轮。
## 7.21.12 Pitch Actuator outputs
• Pitch Angle The current pitch angle of the blade
• Pitch rate The current rate of pitching of the blade
• Pitch acceleration The current acceleration of pitching of the blade
• Demand Pitch Angle/Rate The input demand from the controller into the actuator system
• External Pitch Bearing Moment This is the load that comes from the blade due to aerodynamic and inertial loading, acting on the bearing. When the rotor is clockwise, the sense of the load is opposite to that of GL Blade z-axis, but is the same sense for an anti-clockwise rotor.
• Pitch Bearing Friction The total friction (kinetic or static) acting on the pitch freedom.
• Pitching Inertia The total pitching inertia consisting of the outboard blade inertia plus the referred motor rotational inertia if a rotary actuator is defined.
• Pitch actuator torque (rotary actuator drive or no drive defined) The torque provided by the pitch motor. Defined on the motor side of the gear ratio.
• Pitch actuator force (linear actuator drive) The force provided along the line of the actuator ram.
• Controller demanded pitch angle/rate (setpoint trajectory planning defined) The input demand from the controller before being limited by setpoint trajectory planning.
• Limited demanded pitch angle/rate (setpoint trajectory planning defined) The demand after it has been limited by setpoint trajectory planning.
• Motor position/rate/acceleration (When a flexibility in the actuator drive is defined) Kinematics the motor side of the gear ratio and drive flexibility
• 变桨角度 叶片的当前变桨角度
• 变桨速率 叶片的当前变桨速率
• 变桨加速度 叶片的当前变桨加速度
• 需求变桨角度/速率 控制器输入到执行器系统的需求
• 外部变桨轴承力矩 这是由于气动力学和惯性载荷作用在叶片上作用于轴承的载荷。当风轮顺时针旋转时载荷方向与GL叶片z轴方向相反反之则相同。
• 变桨轴承摩擦 作用于变桨自由度的总摩擦力(动摩擦或静摩擦)。
• 变桨惯量 总变桨惯量,包括外端叶片惯量,以及如果定义了旋转执行器,则参考的电机旋转惯量。
• 变桨执行器扭矩(旋转执行器驱动或无驱动定义) 由变桨电机提供的扭矩。定义在齿轮比的电机侧。
• 变桨执行器推力(线性执行器驱动) 沿执行器推杆方向提供的推力。
• 控制器需求变桨角度/速率(定义了设定点轨迹规划) 在被设定点轨迹规划限制之前,控制器输入的变桨角度/速率需求。
• 限制后的需求变桨角度/速率(定义了设定点轨迹规划) 在被设定点轨迹规划限制后的需求。
• 电机位置/速率/加速度(当执行器驱动定义了柔性时) 齿轮比和驱动柔性定义的电机侧的运动学参数。
