A type of ActuatorDrive
Properties
ActuatorDriveType: string
Defines the specific type of ActuatorDrive model in use. For a RotaryDrive object, this must always be set to a value of RotaryDrive.
TorqueResponse: object (a type of ActuatorResponse), optional
The definition of how the pitch actuator responds to pitch demand.
Can be any of the following types:
GearRatio: number, optional
The combined gearbox and pinion to ring gear ratio (gearbox ratio multiplied by pnion to ring gear ratio).
default = 1
GearEfficiency: number, optional
The efficiency between actuator motor and bearing.
default = 1
MotorInertia: number (kgm²), optional
The rotational inertia of the motor, referred to the high speed side of the pitch gearbox.
default = 0
BrakeTorque: number (Nm), optional
The maximum restraining brake torque applied when the safety limit switches are tripped or permanently on in idling and parked simulations.
default = 0
TorqueLimits: object(PitchTorqueLimits), optional
The limits on the torque that the actuator can apply under normal power.
BackupPowerTorqueLimits: object(PitchTorqueLimits), optional
The limits on the torque that the actuator can apply under backup power.
TorqueLimitsOnceSafetySystemTripped: object(PitchTorqueLimits), optional
The limits on the system once the safety system has been tripped. These may be different from those during standard operation.
LinearSpringDamper: object(LinearSpringDamper), optional
The definition of a linear spring damper.
