Simply stated, aerodynamic stall occurs when the blade's angle facing the oncoming wind becomes so steep that it starts to eliminate the force of lift, decreasing the speed of the blades. Active stall control - The blades in this type of power-control system are pitchable, like the blades in a pitch-controlled system.

Gas turbine - Wikipedia

A gas turbine, also called a combustion turbine, is a type of continuous and internal combustion engine.The main elements common to all gas turbine engines are: an upstream rotating gas compressor; a combustor; a downstream turbine on the same shaft as the compressor.; A fourth component is often used to increase efficiency (on turboprops and turbofans), to convert power into
