Blade [time] sensor

The Blade sensor [time series] can be added by clicking the sensor icon in the blade part, as shown in the following picture:



Another type of blade sensor can be added: the Blade [Span] sensor


The Blade [Time series] sensor provides the following fields:

FieldUnitDescription
Root force (magnitude)kNMagnitude of the reaction force at the root of the blade.
Root moment (magnitude)kNmMagnitude of the reaction moment at the root of the blade.
Root moment (out-of-plane)kNmMoment at the root of the blade around the y-axis. Note that this axis does not pitch with the blades, i.e. it remains unchanged when the blades are pitched.
Root moment (in-plane)kNmMoment at the root of the blade around the x-axis. Note that this axis does not pitch with the blades, i.e. it remains unchanged when the blades are pitched.
Root moment about shaftkNmMoment at the root of the blade around the axis of the shaft. If the cone angle set in the Rotor part is 0, this will be equal to the in-plane root moment.
Pitch angledegThe pitch angle of the blade. If the Rotor Actuator mode  parameter is set to No structural pitch, then the demanded pitch is displayed (and not the structural pitch). See the Pitch actuators part for more info.
Tip deflection (out-of-plane) mOut-of-plane displacement of the Blade aerodynamical station at the tip. Note: Only active (relevant) when the Analysis parameter  Rotor model is set to Flexible
Tip deflection (in-plane)mIn-plane displacement of the Blade aerodynamical station at the tip. Note: Only active (relevant) when the Analysis parameter Rotor model is set to Flexible.
Root torquekNmBending moment (torque) at the root of the blade around the pitch axis. Note: Only active (relevant) when the Analysis parameter Rotor model is set to Flexible.


Note on the sign of the root torque: the root torque is the response torque at the root of the blade along the pitch axis, and the positive direction goes from the root to the tip. In the example illustrated by the figure below, we apply a torque at the tip of the blade in the z-direction (corresponding to the pitch axis in this simulation) and positive in the positive z-direction. The response torque will therefore be negative in the z-direction, and the root torque sensor will have a negative value.
