The number of blades in wind turbine is not determined by aesthetics but by science. The size, shape, solidarity, and positioning is determined by the weather conditions and power output. Current tubbiness include turbines using vortexes (no blades) and high solidarity turbines (12 blades) once popular on farms to pump water.If the model is a replica of actual turbine the number of blades in the model will be the same as the number in the actual unit.
There are 3 blades3 blades on each turbine

Farmers used wind energy, the wind mills also pumped water as their blades swung.
