COOLING SYSTEM FOR HIGH TEMPERATURE COMPONENT OF AIRCRAFT ENGINE AND AIRCRAFT ENGINE EQUIPPED WITH THE SAME

摘要

PPROBLEM TO BE SOLVED: To provide a cooling system for an aircraft engine, solving the problem that it is difficult to access several components of the engine for maintenance, there is a risk of the circulation of air in the opposite direction or no circulation thereof, and pressure loss in a heat exchanger is increased when the risk of the recirculation of air in the heat exchanger is eliminated. PSOLUTION: The cooling system for the aircraft engine 10 comprises a channel 32 from which low temperature air in a secondary air flow 200 is removed and the heat exchanger 34 arranged in the channel 32, in which high temperature air is circulated. The channel 32 has a supply pipe 322 fixed to a nacelle 24 and an exhaust pipe 326, and an intermediate box 324 arranged between the supply pipe 322 and the exhaust pipe 326 and fixed to the engine 10, in which the heat exchanger 34 is arranged.
