Touchdown velocity for given stall velocity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Touchdown Velocity = 1.3*Stall Velocity
V_T = 1.3*V_stall
This formula uses 2 Variables

Variables Used

Touchdown Velocity - (Measured in Meter per Second) - Touchdown Velocity is the instantaneous velocity of an aircraft when it touches the ground during landing.
Stall Velocity - (Measured in Meter per Second) - Stall Velocity is defined as the velocity of an airplane in steady flight at its maximum lift coefficient.

STEP 1: Convert Input(s) to Base Unit

Stall Velocity: 148 Meter per Second --> 148 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_T = 1.3*V_stall --> 1.3*148

Evaluating ... ...

V_T = 192.4

Landing ground roll distance

LaTeX Go Landing Roll = 1.69*(Weight^2)*(1/([g]*Freestream Density*Reference Area*Maximum Lift Coefficient))*(1/((0.5*Freestream Density*((0.7*Touchdown Velocity)^2)*Reference Area*(Zero-Lift Drag Coefficient+(Ground Effect Factor*(Lift Coefficient^2)/(pi*Oswald Efficiency Factor*Aspect Ratio of a Wing))))+(Coefficient of Rolling Friction*(Weight-(0.5*Freestream Density*((0.7*Touchdown Velocity)^2)*Reference Area*Lift Coefficient)))))

Landing Ground Run

LaTeX Go Landing Ground Run = (Normal Force*Velocity at Touchdown Point)+(Weight Of Aircraft/(2*[g]))*int((2*Velocity of Aircraft)/(Reverse Thrust+Drag Force+Reference Of Rolling Resistance Coefficient*(Weight Of Aircraft-Lift Force)),x,0,Velocity at Touchdown Point)

How fast is an airplane going when it lands?

Big commercial airplanes generally fly in the 550-580 MPH range, but their landing and taking-off speeds are naturally different. Most commercial planes take off at roughly 160 to 180 MPH, while landings take approximately 150 to 165 MPH.

How to Calculate Touchdown velocity for given stall velocity?
