In flight mechanics, rolling resistance force refers to the resistance encountered by an aircraft as it moves along the ground. This force arises from the friction between the aircraft’s tires or landing gear and the runway surface. Rolling resistance is influenced by factors such as tire characteristics, runway conditions, and the weight of the aircraft. The formula to calculate Rolling resistance force as follows:
Where:
- R is the Rolling Resistance Force in N.
- μr is the Coefficient of Rolling friction.
- W is the Weight in N.
- L is the Lift Force in N.
