Calculation and analysis of a ventilation and cooling scheme for aircraft brake assembly

Abstract

Abstract The slow cooling of brake assembly of civil aircraft is one of the major constraints on the operational efficiency of the aircraft. Aiming at the engineering problem of brake carbon heatpacks in flight cooling, this article proposes a ventilation and cooling scheme for aircraft brake assembly, which is based on the original configuration of the main landing gear compartment of the aircraft. By adding the design of the intake duct and exhaust grille, external cooling airflow is introduced to cool the brake carbon heatpacks during flight. This article confirms the cooling effect through simulation calculations and experimental data. This article can provide a reference for the ventilation and cooling design of civil aircraft brake assembly.
