Abstract : The aircraft landing gear undergoes severe stress and temperature gradient within a short span of time from
braking to stoppage. The kinetic and the potential energy of the aircraft are converted to the rotational energy by the wheels,
which are then transformed to heat energy through braking systems. The current generation of braking systems consists of an
array of stators and rotors lined up together in a T-formation incorporated within the hub of the wheel. The rotors are
connected to the wheel hub via the torque tube and rotate with the wheel. When the brakes are applied, the piston housed in
the brake presses the rotors against the stators and the kinetic energy of the wheels is converted into heat. The temperature of
the brake linings, discs and other peripheral systems can reach from 500° C to 2000° C. Therefore, designing a robust
braking is imminent to ensure safety of the plane. In this paper, a design methodology for designing brakes of an aircraft has
been discussed, historical and current material selection trends for the brakes and using the accumulated data, a numerical
example is solved taking in account the data of a Boeing 737 aircraft. The Boeing 737 has historically used steel brakes
followed by carbon brakes in the newer versions. Here, it is simulated using a newer material: Aluminum Metal Matrix
Composite (AMMA). The rotor (produced by Parker Cleveland)is modeled in SolidWorks 17 and structural and thermal
analysis of the brake disc is performed using ANSYS 18.2.
