Calculation of temperature of carbon disks of aircraft brakes with account of heat exchange with the environment

• The temperature of the tribosurface of aircraft-brake carbon disk during braking is studied. Formula is advanced to calculate the temperature based on the geometrically one-dimensional unsteady heat model taking into account the convective heat exchange of the lateral surfaces of the disk with the air environment. Friction experiments with lab specimens made from the carbon material Termfar-ADF demonstrate the temperature variations. The experimental results are compared with the calculated results.
