Stall Speed
In aerospace engineering, 'Stall Speed' refers to the minimum airspeed at which an aircraft or an airfoil can maintain level flight without stalling. A stall is a condition in aerodynamics and aviation where the angle of attack increases beyond a certain point such that lift begins to decrease. The stall speed is typically denoted as 'Vs'. It is a critical performance parameter for any aircraft, and it is usually provided by the aircraft manufacturer. The stall speed is influenced by several factors including the aircraft's weight, altitude, load factor (g-force), and configuration (flaps, landing gear). For instance, an increase in weight or altitude, or a higher g-force, will increase the stall speed. Conversely, deploying flaps or landing gear can decrease the stall speed by increasing the wing's lift coefficient. Understanding and managing stall speed is crucial for pilots to maintain control of the aircraft, especially during takeoff and landing phases.
