Liftoff velocity for given stall velocity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Liftoff velocity = 1.2*Stall Velocity
V_LO = 1.2*V_stall
This formula uses 2 Variables

Variables Used

Liftoff velocity - (Measured in Meter per Second) - Liftoff velocity is defined as the velocity of the aircraft at which it first becomes airborne.
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

Coefficient of rolling friction during ground roll

LaTeX Go Coefficient of Rolling Friction = Rolling Resistance/(Weight-Lift)

Lift acting on aircraft during ground roll

LaTeX Go Lift = Weight-(Rolling Resistance/Coefficient of Rolling Friction)

Weight of aircraft during ground roll

LaTeX Go Weight = (Rolling Resistance/Coefficient of Rolling Friction)+Lift

Resistance force during ground roll

LaTeX Go Rolling Resistance = Coefficient of Rolling Friction*(Weight-Lift)

What is the stall angle of attack?

A stall occurs when the angle of attack of an aerofoil exceeds the value which creates maximum lift as a consequence of airflow across it. This angle varies very little in response to the cross-section of the (clean) aerofoil and is typically around 15°.

How to Calculate Liftoff velocity for given stall velocity?

Liftoff velocity for given stall velocity calculator uses Liftoff velocity = 1.2*Stall Velocity to calculate the Liftoff velocity, Liftoff Velocity for Given Stall Velocity is a measure of the minimum speed required for an aircraft to take off, calculated by multiplying the stall velocity by a safety factor of 1.2, ensuring a safe margin above the stall speed to prevent engine failure or loss of control during critical phases of flight. Liftoff velocity is denoted by V_LO symbol.

How to calculate Liftoff velocity for given stall velocity using this online calculator? To use this online calculator for Liftoff velocity for given stall velocity, enter Stall Velocity (V_stall) and hit the calculate button. Here is how the Liftoff velocity for given stall velocity calculation can be explained with given input values -> 177.6 = 1.2*148.

FAQ

What is Liftoff velocity for given stall velocity?

Liftoff Velocity for Given Stall Velocity is a measure of the minimum speed required for an aircraft to take off, calculated by multiplying the stall velocity by a safety factor of 1.2, ensuring a safe margin above the stall speed to prevent engine failure or loss of control during critical phases of flight and is represented as V_LO = 1.2*V_stall or Liftoff velocity = 1.2*Stall Velocity. Stall Velocity is defined as the velocity of an airplane in steady flight at its maximum lift coefficient.

How to calculate Liftoff velocity for given stall velocity?
