V S: Stall speed: the speed at which the airplane exhibits those qualities accepted as defining the stall. [26]: 8 V S0: The stall speed or minimum steady flight speed in landing configuration. [27] The zero-thrust stall speed at the most extended landing flap setting. [26]: 8 V S1: The stall speed or minimum steady flight speed obtained in a ...
Stall speed or minimum steady flight speed for which the aircraft is still controllable in a specific configuration. [7] [8] V S R: Reference stall speed. [7] V S R 0: Reference stall speed in landing configuration. [7] V S R 1: Reference stall speed in a specific configuration. [7] V SW: Speed at which the stall warning will occur. [7] V TOSS
Note the 1g stall speed, and the Maneuvering Speed (Corner Speed) for both positive and negative g. The maximum “never-exceed” placard dive speeds are determined for smooth air only. In aviation, the maneuvering speed of an aircraft is an airspeed limitation at which the full deflection of the controls can be made at without risking ...
A load factor greater than 1 will cause the stall speed to increase by a factor equal to the square root of the load factor. For example, if the load factor is 2, the stall speed will increase by a ratio of , or about 140%. [citation needed]
Wing loading is a useful measure of the stalling speed of an aircraft. Wings generate lift owing to the motion of air around the wing. Larger wings move more air, so an aircraft with a large wing area relative to its mass (i.e., low wing loading) will have a lower stalling speed.
Stall speed corresponds to the angle of attack at the maximum coefficient of lift (C LMAX) A typical lift coefficient curve for an airfoil at a given airspeed. The lift coefficient of a fixed-wing aircraft varies with angle of attack. Increasing angle of attack is associated with increasing lift coefficient up to the maximum lift coefficient ...
The angle at which maximum lift coefficient occurs is the stall angle of the airfoil, which is approximately 10 to 15 degrees on a typical airfoil. The stall angle for a given profile is also increasing with increasing values of the Reynolds number, at higher speeds indeed the flow tends to stay attached to the profile for longer delaying the ...
Graphs of C L and C D vs. speed are referred to as drag curves. Speed is shown increasing from left to right. The lift/drag ratio is given by the slope from the origin to some point on the curve and so the maximum L/D ratio does not occur at the point of least drag coefficient, the leftmost point. Instead, it occurs at a slightly greater speed.
