Comparison of two mathematical models of the kite for Laddermill sail simulation

Laddermill sail is an innovative approach to propel the ship with the power generated by kites. The first Laddermill system is currently being designed however existing mathematical models of the system produce different optimal recommendations. Thus a decision has been made to step back and to take a closer look at the mathematical models of Laddermill sail. Each kite is considered a single rigid body as is the ship. It’s been found that the differences between results might come from the fact that the two models possess features of the kite that cannot be combined in the rigid wing approach. More adequate modelling of controlling mechanisms will allow adequate modelling of Laddermill sail as a whole.
