In this era of expensive fossil fuels, many alternativeshave been pursued. One idea from SkySails, Inc., shownin Fig. is the assisted propulsion of a ship by a largetethered kite. The tow force of the kite assists the ship’spropeller and is said to reduce annual fuel consumptionby 10–35 percent. For a typical example, let the ship be120 m long, with a wetted area of 2800 m2. The kite areais 330 m2 and has a force coefficient of 0.8. The kite cablemakes an angle of 258 with the horizontal. Let Vwind =30 mi/h. Neglect ship wave drag. Estimate the ship speed(a) due to the kite only and (b) if the propeller delivers1250 hp to the water. [Hint: The kite sees the relativevelocity of the wind.]
