The hull design also allows for a larger propeller diameter
than usually found in a double ended ferry.
Key words: wind-mill motor, propeller diameter, propeller revolutions, rotor blade
0], propeller diameter D, propeller revolutions n and the number of blades z (Svrcek, 2009).
Secondly, the optimisation of the propeller diameter
and shaft speed can be evaluated to see if further efficiency improvements are possible.
velocity, tank diameter, liquid viscosity, propeller diameter
Now, it's known that thrust (T) is related to propeller diameter (D), propeller speed (n) (revs/sec.
The Wright brothers could measure their propeller diameter to within 0.
1] which corresponds with the propeller diameter and the other one of radius [R.
Considering that water is the working liquid and that the propeller diameter is d = 1 m and the rotating speed n = 2,5 rot/s, one obtains:
A]/nD), n=propeller rotational speed in rps, and D = propeller diameter
Larger propeller diameters
are preferred for low airspeed operation, while smaller diameters are best for high airspeeds.
