The mass properties of the hub.

  • Mass: number (kg)
  • AxialPositionOfCentreOfGravity: number (m)
  • MomentOfInertiaAboutShaft: number (kgrad²)
  • MomentOfInertiaPerpendicularToShaft: number (kgrad²)

Properties

Mass: number (kg)

The total mass of hub including the pitch system, but excluding contribution from the blades connected to it.

AxialPositionOfCentreOfGravity: number (m)

The hub centre of gravity, relative to intercept of blade pitch axis and drivetrain axis (the hub centre), positive direction being along drivetrain axis towards the hub.

MomentOfInertiaAboutShaft: number (kgrad²)

The total moment of inertia of hub about the low speed shaft, including the pitch system but excluding contribution from the blades connected to it.

MomentOfInertiaPerpendicularToShaft: number (kgrad²), optional

The total moment of inertia of hub perpendicular to the low speed shaft, including the pitch system but excluding contribution from the blades connected to it.
