Substituting the expression into formula we obtain the
The tether XL184 characterized by its average operating length, l, diameter, d, mean angle of inclination to the horizon, ? , and normal reaction (drag) coefficient, C⊥C⊥ (with a typical value of 1.0). Structural parameters and design variables of the kite wind generator have been distinguished in Table 2 (see also Fig. 4).

In the United States, the Federal Aviation Administration restricts wind turbines to a maximum height of 500 feet. In accordance with Z lines regulations, the maximal height of operating kites must also be restricted to the same height z* = 152 m. This height constraint can be formulated as follows:equation(20)rsin?≤z*.rsin?≤z*.
