Rolling Friction coefficient Given By Rolling Resistance Calculator

In flight mechanics, rolling friction coefficient refers to the resistance an aircraft experiences during ground taxiing and takeoff roll due to friction between its tires and the runway surface. A lower rolling friction coefficient allows for smoother acceleration and contributes to more efficient takeoffs. This coefficient is crucial in predicting ground handling characteristics, influencing an aircraft’s performance during ground movements. Aircraft designers aim to optimize tire design and runway conditions to minimize rolling friction and enhance overall operational efficiency. The formula to calculate rolling friction coefficient as follows:

Where:

  • μr is the Rolling Friction coefficient.
  • R is Rolling resistance in N​.
  • W is the weight in N.
  • L  is the Lift force in N.
