Propulsion Kite Models Sample Clauses

Propulsion Kite Models. As with the Flettner Rotors, Kit systems have both lift and drag forces acting on them, therefore, as before; Where; ρ = Density of fluid [kg m−3] (dependent on temperature) U = Speed of fluid in the frame of reference of the cylinder [ms-1] A = Cross sectional area [m2] CL= Coefficient of lift [-] CD= Coefficient of drag [-] A kite system will have quite different values of CL and CD. In the case of the Flettner Rotor, these are dependent on the shape, angular velocity of spin, and apparent wind speed experienced by the rotor. In the case of kites, they CL and CD values are dependent on the shape, angle of attack and apparent wind speed. These values can be calculated experimentally, but for very simple shapes can be simply calculated. There are many example profiles in the literature for kites, one recent profile is in 2014 is shown in Table 51 and plotted in Figure 79. These example figures will be used for modelling a kite system in INOMANS2HIP. Figure 80 shows the kite model block created in GES. The in- and outputs are defined in Table 52.
