How to Calculate Touchdown velocity?
Touchdown velocity calculator uses Touchdown Velocity=1.3*(sqrt(2*Weight/(Freestream density*Reference Area*Maximum Lift Coefficient))) to calculate the Touchdown Velocity, The Touchdown velocity is a function of instantaneous weight, freestream pressure, and maximum lift coefficient of the aircraft. Touchdown Velocity and is denoted by V_{T} symbol.
How to calculate Touchdown velocity using this online calculator? To use this online calculator for Touchdown velocity, enter Weight (W), Freestream density (ρ_{∞}), Reference Area (S) and Maximum Lift Coefficient (C_{L,max}) and hit the calculate button. Here is how the Touchdown velocity calculation can be explained with given input values -> 5.783135 = 1.3*(sqrt(2*100/(1.225*5*1.65))).
