• BackupPowerForceLimits: object (PitchForceLimits)
• RadiusOfArm: number (m)

A type of ActuatorDrive

Properties

ActuatorDriveType: string

Defines the specific type of ActuatorDrive model in use. For a LinearActuator object, this must always be set to a value of LinearActuator.

ForceResponse: object (a type of ActuatorResponse), optional

The definition of how the pitch actuator responds to pitch demand.

Can be any of the following types:

• InstantaneousActuatorResponse
• FirstOrderActuatorResponse
• SecondOrderActuatorResponse

PivotOffset: number (m)

The distance between the pitch axis and the pivot centre for the ram.

PitchAngleAtMaximumTorque: number (rad)

The pitch angle when the ram is perpendicular to the moment arm radius.

BrakeForce: number (N), optional

The maximum restraining brake force applied when the safety limit switches are tripped or permanently on in idling and parked simulations.

default = 0

ForceLimits: object(PitchForceLimits), optional

The limits on the forces that the actuator can apply under normal power.

BackupPowerForceLimits: object(PitchForceLimits), optional

The limits on the forces that the actuator can apply under backup power.

RadiusOfArm: number (m)

The distance between the pitch axis and the connection point of the ram.
