Remarks

A track generally describes the structural connection between a control surface and a wing (or parent element). For example, a track can be a flap track, a revolute joint connecting an aileron or spoiler, or the kinematics of slats on a wing.

The spanwise position of the track is defined by etaPosition, which refers to the control surface dimensions.

The structural properties of the track (e.g. materials) are defined in trackStructure.

If an actuator is included into the the track, a reference is given in actuator.

The principal kinematic of the track is defined by setting the trackType and trackSubType. Please refer to the tables below for setting the trackType and trackSubType parameter. Note, those tables are not final - they are extended continuously.

1
TrackType1
Revolute joint; no actuators; the revolute joint is on TED hinge line.1
TrackType1
Revolute attached at the wings rear spar and the TEDs front spar respectively the load carrying ribs of the TED.
2
TrackType2
Revolute joint; dropped hinge; linear or rotary actuator (subtype-dependent) included. The drive strut (if any) is defined as strut1.1
TrackType2
Box beam design as wing attachment; rotary drive attached at wing rear spar.
2
TrackType2_SubType2
Wing attachment at wing rear spar; rotary drive attached at wing rear spar
3Track mounted inside the fuselage at wing root.
3
TrackType3
Upside-down, forward link in conjunction with a straight track on a fixed structure as aft. support; including rotary drive.1
TrackType3
Wing attachment using a box beam design where track is mounted; rotary actuator mounted at the wing rear spar.
2Track mounted inside the fuselage at wing root.
4
TrackType4
Straight and sloped track on a fixed structure as forward support and an upright link as aft. support; linear or rotary actuator (subtype-dependent) included.1
TrackType4
Wing attachment using a box beam design where the track is mounted; rotary actuator at the wing rear spar.
2
TrackType4_SubType2
Wing attachment using a box beam design where track is mounted; rotary actuator mounted on the track.
3Track mounted inside the fuselage at wing root.
