Abstract

The slow cooling of air brake carbon disc of civil aircraft is one of the important reasons that restrict the reliability of aircraft brake system. Aiming at the engineering problem of brake carbon disc in flight cooling, this paper proposes two ventilation schemes for aircraft main landing gear compartment, and carries out refined numerical simulation for the two schemes, compares and analyses the ventilation and cooling effects of the two schemes in detail, and weighs the analysis benefits and costs. The calculation results show that the 170mm inlet opening height of plan A has a better overall ventilation effect on the landing gear compartment, and the cooling effect of the upper and lower brake carbon disk is more uniform. Plan B can achieve better cooling effect near the brake carbon disc, but it brings a large fuel compensation loss, so it is necessary to select plan A or B according to the actual situation.
