Check this box to show KaroroTUNE
TIP: You should be in Rhino Front View and may need to zoom out to see the tuning bridle to the left of the kite model
Push this button to start a tune.
PLEASE NOTE: KaroroTUNE will check that you have all data selected and you have a valid license before starting a tune.
PLEASE NOTE: KaroroTUNE is computationally taxing on your system, expect your machine's response to slow down across all processes you have open while running a tune.
Sets the Kite Angle of Attack for the Bridle for Tune. Higher numbers will move the Tow Point of the bridle backwards, lower numbers will move the Tow Point forward.
Width Factor controls the goal pressure distribution across the attachment points of the bridle that KaroroTUNE will search for.
A Width Factor of 0 is even distribution - ie 25% on each attachment point for a 4 point bridle
A Width Factor of greater than 0 moves the loading bias towards the wing tip, a Width Factor of les than 0 moves the loading bias towards the center of the kite.
TIP: Check the Show Pressure Goals check box to have a visual feedback on the effect of Width Factor
Checking this box will bring up a visual indication of the goal pressure distribution across the attachment points of the bridle that KaroroTUNE will search for.
NOTE: This is a % of the total pressure in the all the lines that attach directly to the kite. The actual display pressure in the bridle tune will be higher than these figures
Equality Factor gives a loading factor to the even-ness of the lengths of sub-cascades in the bridle. This factor helps prevent the tune from finding solutions that are overly un-even but provide the required Width Factor solution.
TIP: Reducing the Equality Factor can sometimes help resolve a tune that may not resolve to a solution with a higher Equality Factor
Sets the seed for the initial bridle set generation - experienced users may run the same tune on a different seed to 'steer' the bridle to a valid solution
Saves the tensions from the latest tune to the current Karoro session.
This sets all bridle tensions back to 125 and clears the tune pipeline cache.
TIP: Press this button between tunes to always start at a known setup.
Press this button after completion of a bridle tune will export the tuned bridle to a new layer in the active Rhino document.

NOTE: If there are not enough bridle points selected in your Bridle Point Selection for a given bridle style selected the display output is 'un-defined'
NOTE: If you do not see the bridle you are looking for please contact us for custom bridle options - these can be added within 48 hours if required
This table selects which bridle attachment points will be used, based on one half of the kite. Left most figure is the center attachment point, moving towards the wingtip as you go right. A 1 indicates a bridle point is used and 0 is a bridle point in not used. Figures beyond the number of attachments needed for the bridle are ignored.
By default KaroroCAD places bridle tow points at the intersegment seams and at the point that is closest to the control bar at zero AOA.
This control gives an offset rotation to the upper most tow point (in the middle of the kite). All the other tow points down the kite will get a weighted rotation, with the lowest not being effected.
NOTE: Positive Numbers rotate towards the rear of the kite, Negative towards the front.

By default KaroroCAD places bridle tow points at the intersegment seams and at the point that is closest to the control bar at zero AOA.
This control gives an offset rotation to the lower most tow point (at the wing tip panel seam). All the other tow points up the kite will get a weighted rotation, with the highest not being effected.
NOTE: Positive Numbers rotate towards the rear of the kite, Negative towards the front.
NOTE: If there is both a Upper and Lower Tow Point Rotation the weight sum of the two factors are applied across the other tow points.
This control allows for a non linear weighting of the rotations of the control points between the upper and lower tow points.
As as standard KaroroKITE puts a tow point on every intersegment seam of the Leading Edge. Checking this box will add extra tow points mid way between the standard tow points.
This sets the overall length of the bridle. The units are % of the vertical height of the kite, and measured from the lowest point of the kite down.
KaroroKITE includes the front flying lines in the calculation of the bridle shape and loads. Enter your control bar line length here.
Enter the required number of Rear Line Attachments here.
How far in mm the rear most Rear Line Attachment point will be offset from the trailing edge corner of the kite.
Sets the spacing in mm between multi rear line attachment points.
This provides a separate control for the relative length of the rear line bridle. After testing a particluar kite design you can use this control to match the front to rear balance of the line lengths.
KaroroKITE uses the bar length to help create the rear line bridle length - enter the length of the control system you expect to use with this kite size.
Adjusts the angle of the Rear Line reinforcement Vee
Save kites will load tension settings into these parameters
