In addition, this type of WIG that are propelled from the water can suffer significant destabilization and difficulties in their maneuverability when the wind and waves are crossed and do not coincide with the direction of movement of the WIG propelled from the water. For this it is necessary to make both its water propellers and its air propellers "Steerable" to accommodate the wing structure to each wind condition that exists at all times.
The three types of applications that may be more convenient to use this type of boats are:
1_ In recreational yachts and sports or fishing boats with a length greater than 6 or 8 meters. In this case, when these boats move at low speed, they will be able to do it 100% with solar energy, and if they need a higher speed to move, they will be able to do it at a higher speed than these boats at present. In addition, when they are anchored or without movement, they can take advantage of the solar energy to recharge the electric batteries that they carry.
3_ In Ferries for the transport of people or loads from short to long distances.
In the case of transporting heavy loads at low or intermediate speeds, this type of solar Hydrodinamic WIG will surely be used in conjunction or superimposed with other types of propulsion systems such as battery-powered boats, or solar boats with the solar panel holder system telescopic type.
In the case of transporting people or light or intermediate loads at high speeds, the use of this type of solar Hydrodinamic WIG will also surely be used in conjunction or overlapping with other propulsion systems such as current high-speed boats powered by batteries electric or by the use of WIG or ground effect aerial vehicles where the use of WIG will begin to be more convenient than the use of our solar Hydrodinamic WIG, when the distances are greater, and when they need to take off or land from land airports in areas from the interior of the country.
The fuel consumption per ton transported and the ratio of the transported load with respect to the total weight of the loaded Hydrodynamic WIG given in the tables shown in the figures are estimates and their values depend on the efficiency of the ground effect that is achieved with the WIG during its operation, the own weight with which this boat is manufactured and the weight of the fuels or electric batteries used.
How the maximum ratio of the lift coefficients Cl and drag Cd is 65, for the chosen wing profile and taking into account the decrease in this value due to the extra drag generated by the hull and other components of the boat , but considering that the ground effect achieved by this boat can become similar or greater than those achieved by the Ekranoplanes and be able to double the final relationship between the lift force L and the resistance force D. It is because These reasons we consider for the calculation of the fuel consumption of the boat at values of the ratio R=L/D, of the order of 30, 40 and 50.
In addition, considering that a good relationship between the ship's own weight and the transported load can be 50%, and if the trip is long distance, where it would be necessary to carry a lot of weight in electric batteries or fuel or if the weight The Hydrodynamic WIG itself is high, the percentage of the transported cargo can fall to an estimated value of 40%. That despite being a low value, it is higher than that of long-distance airplanes since the Ekranobarco can be built without the need to be pressurized or have as many aerodynamic and design requirements as said airplanes.
Furthermore, in these calculations, we estimate that the Ekranobarco's engine will be a Diesel engine with an efficiency of 30% and that the efficiency of the set of supercavating water propellers and guided flow air propellers will be around 75%.
The energy consumption calculations will be made for the case of a weight of 1 Ton or 9,800 Newton and a distance of 100 Km or 100,000 meters.
In these results we can see that the estimated consumption for the Hydrodynamic WIG would be lower than the consumption per load transported by an airplane, but higher than the case of a truck or the rest of the transport systems of large loads such as railways or interoceanic ships.
In principle, according to the results obtained, this type of WIG would be justified as a use for the transport of light or intermediate loads, or of people over short, intermediate or long distances. And what would also be interesting especially that it can be used in refrigeration loads for intermediate or long distances.
