DI 18 - Square Cuts

Doubts & discrepancies

Uncertain readings of the diagram or the official text, and disagreements between sources, to be validated. The animation follows the reading we chose, which is not an official interpretation.

No specific doubt or discrepancy about this figure.

Common to the whole family of figures

• douteOverall speed: we chose a constant speed of 15 units per second (about 4.4 m/s with 37 m lines), without any flight measurement. The ISK requires a constant speed (§II.V) without giving a value.
• douteKite size: our assumption is a wing 2.30 m wide, i.e. 8 grid units (1 unit ≈ 0.29 m with 37 m lines), with the proportions of the Hadzicki wing drawn in kite-physics; the dual-line wing has the same span. For the reference competition, we only found the scale of the grid (ISK §II.C: about 0.3 m for 38 m), not a kite size. At this size, the wings of a team overlap at times (MT 01, 02, 06 and 09). Lead: a smaller kite.
