Description

      Element parentUID[0, 1]

UID of the parent component. If set, the position of the main strut is defined relative to the parent coordinate system.

      Element control[0, 1]

Landing gear control parameters

                  Element totalLength

Total length of landing gear, equals the distance from the middle of the bogie/axles to the axis of rotation of the pintle strut. Distance is measured while landing gear is fully extended and in airborne condition (i.e., if a spring is present, the totalLength includes the springDeflectionLength)

                  Element staticSuspensionTravel[0, 1]

Static suspension travel means the positive distance between the total length in airborne condition and the reduced length due to compression on the ground.

                  Element compressedSuspensionTravel[0, 1]

Compressed suspension travel means the positive distance between the total length in airborne condition and the maximum reduced length due to maximum compression on the ground (e.g., landing shock).

            Element componentAssembly

Assembly of landing gear components

      Element transformation

Transformation with respect to the uppermost point of the main strut. From this point the landing gear is oriented in negative z-direction by default.
