Aircraft arrester gear (AAG) system, which is a ground based emergency braking system, is used to bring fighter aircrafts to halt by converting kinetic energy of incoming aircraft to frictional heat energy of the emergency brakes. However, the rise in temperature of the brake disc of emergency braking system in an AAG is difficult to measure practically. Hence a mathematical way of estimating temperature rise is discussed. The paper describes temperature rise in the brake disc by solving heat transfer equations with finite difference method. The equations are solved iteratively using MATLAB and the best case temperature rise 3400°C and the worst case temperature rise 1200°Cis obtained based on the area available for heat dissipation. Finite element analysis is done using ABAQUS and ANSYS to validate the temperature rise. Experimentation is also performed by developing a prototype for dynamic energy generation and further its absorption to observe the temperature rise in the brake discs. The theoretical solution is validated with the experimental results. It is concluded that uniform contact of the brake discs is an important parameter to limit the temperature rise.
