What is a governor blade?

A governor blade is a component in some mechanical systems, particularly in engines and turbines, that helps regulate speed by adjusting the fuel or power input based on the load. It operates as part of a governor system, which maintains a constant speed despite variations in load conditions. When the engine speed increases beyond a set point, the governor blade moves to reduce fuel supply, thereby controlling the engine's output. This ensures optimal performance and prevents damage due to over-speeding.
