Dear users, I have a problem with a calculation. I have got an assignment. For this assignment I have to redesign the brake actuators for the brake discs of the main landing gear of th fokker 100. I have forgotten how to calculate a force that goes sideways. The sideway forces are created when the lineair actuator pushes the brake disc on the wheels. For the calculation I have a few values. - Total brake disc mass: 237,84 kg (90% worn brake, CS25.109i) - CS-25 braking speed is= -3,0 m/s^2 - Assumed distance from neutral position actuator to the wheel= 5 cm - Maximum take-off weight Fokker 100: 44.450 kg - Kinetic energy brake discs: 162 MJ - Maximum actuator force for each actuator: 40.000N - Specific Heat of he brake disk material: 800 J/kg/K - RTO test speed: 85m/s, 166 knots - Effect of air resistance will be ignored, trust reverser and speedbrake on the wing will not be applied. I have a few questions: 1 - Which formula do I need to determine the force that the actuators need to push the brake discs? 2 - How much actuators do I need in total on each wheel? 3 - What is the Work of each actuator? 4 - What is the Power of each actuator? To be clear, I DON'T need to know the maximum kinetic energy capability of the brake disc, these questions are aimed only for the actuators. I need to know how much power the actuator need to produce and how much of them I need them on 1 wheel.
