Assuming negligible uncertainty for the rotor blade radius, the uncertainty associated with the thrust coefficient, [mathematical expression not reproducible], power coefficient, [mathematical expression not reproducible], and roll moment coefficient, [mathematical expression not reproducible], can be obtained using equations (12), (13), and (14) in the form
The thrust of each propeller is calculated by [mathematical expression not reproducible] being the thrust coefficient and [[omega].sub.i] being the angular speeds.
The influence of the stress state applied at the boundary has been evaluated considering the lateral thrust coefficient values of 1, 1.25, 1.67 and 2.5, and attributing a friction angle of 3[degrees] to the discontinuity.
The key performance indexes of a WMR include its traction efficiency (see Figure 18), thrust coefficient and traction coefficient, and drive efficiency.
In the language of wind turbine modeling, the drag coefficient is named the thrust coefficient [C.sub.t]:

It can calculate the thrust coefficient and tip loss factor in another form.
where: [k.sub.T]--the thrust coefficient of the screw that could be taken for study case 0.30/0.40.
The thrust coefficient [K.sub.T] and the torque coefficient [K.sub.Q] are plotted against the advance ratio J.
Furthermore, the thrust coefficient used to characterize propeller performance was not defined until after World War I.
The thrust coefficient (CT), power coefficient (CP), and efficiency (n) are as defined in (1).
