Aircraft Propellers – Introduction to Aerospace

This innovation soon led to the constant-speed propeller, which automatically adjusted blade pitch during flight using a governor [4] to maintain a

Constant Speed Wind Turbine

Constant speed wind turbines are defined as turbines that operate with a fixed angular speed of the rotor, regardless of the wind speed, typically using induction or synchronous generators.

Wärtsilä Shaft Generator

Shaft generators on board ships are driven by the main engine to supply power to the mains. The mains have to be supplied with constant voltage and frequency by the shaft generator whilst

Wind turbine design

When wind speed falls below the turbine''s rated speed, generator torque is used to control the rotor speed to capture as much power as possible. The most power is captured when the tip

Modern large wind turbines operate at variable speeds. When wind speed falls below the turbine''s rated speed, generator torque is used to control the rotor speed to capture as much power as possible. The most power is captured when the tip speed ratio is held constant at its optimum value (typically between 6 and 7). This means that rotor speed increases proportional to wind speed. The diff
