Resistance force during ground roll Solution

STEP 0: Pre-Calculation Summary

Formula Used

Rolling Resistance = Coefficient of Rolling Friction*(Weight-Lift)
R = μ_r*(W-F_L)
This formula uses 4 Variables

Variables Used

Rolling Resistance - (Measured in Newton) - Rolling Resistance (or Rolling friction) is the force resisting the motion of a rolling body on a surface.
Coefficient of Rolling Friction - Coefficient of Rolling Friction is the ratio of the force of rolling friction to the total weight of the object.
Weight - (Measured in Newton) - Weight Newton is a vector quantity and defined as the product of mass and acceleration acting on that mass.
Lift - (Measured in Newton) - The Lift, lifting force or simply lift is the sum of all the forces on a body that force it to move perpendicular to the direction of flow.

STEP 1: Convert Input(s) to Base Unit

Coefficient of Rolling Friction: 0.1 --> No Conversion Required

Coefficient of rolling friction during ground roll

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

Lift acting on aircraft during ground roll

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

Weight of aircraft during ground roll

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

Resistance force during ground roll

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

Resistance force during ground roll Formula

Rolling Resistance = Coefficient of Rolling Friction*(Weight-Lift)
R = μ_r*(W-F_L)

What does the coefficient of rolling friction indicate?

The coefficient of rolling friction is the indication of how great the rolling resistance is for a given normal force between the wheel and the surface upon which it is rolling.

How to Calculate Resistance force during ground roll?

Resistance force during ground roll calculator uses Rolling Resistance = Coefficient of Rolling Friction*(Weight-Lift) to calculate the Rolling Resistance, Resistance Force During Ground Roll is a measure of the force opposing an aircraft's movement during the ground roll phase of takeoff or landing, calculated by multiplying the rolling friction coefficient by the weight of the aircraft minus the force of lift. Rolling Resistance is denoted by R symbol.
