sci.stall-speed-CL-max Calculator
Calculates aircraft stall speed Vs = √(2W/(ρ × S × CL_max)) and minimum control speed from wing loading and maximum lift coefficient. Stall speed for a 70,000 kg aircraft with S = 180 m² and CL_max = 2.5: Vs ≈ 57 m/s (111 kts) — landing configuration with flaps increases CL_max by 50–80%.
Inputs
W N
Body or object weight. For health calculators, usually in kg or lbs.
S M2
Two-dimensional surface extent (m²). For complex shapes, break into simpler sub-shapes and sum.
Cl Max
Reference formula or conversion factor shown for context.
Rho Kg M3
Mass per unit volume (kg/m³). Water: 1,000. Air: 1.225. Steel: 7,850. Affects buoyancy, flow, and structural loads.
Results
stall speed Vs (m/s)
The computed rate of movement or processing.
stall speed Vs (knots)
The computed rate of movement or processing.
wing loading W/S (N/m²)
Sample size or count used in the calculation.
dynamic pressure at stall q (Pa)
The value at the specified point or condition.
Vs = √(2W/ρSCL_max)
