<p>PROBLEM TO BE SOLVED: To provide an aircraft equipped with a turbofan engine, capable of avoiding an increase in fuel cost and ensuring heat exchange capabilities of an engine oil cooler and a pre-cooler even if an accessory installation space is restricted.SOLUTION: An aircraft equipped with a turbofan engine 10 that includes an engine main body 12 and a fan 13, includes: a core cowl 15 surrounding the engine main body 12; an engine oil cooler 30 serving as a heat exchanger using, as a heating source, a fan stream flowing in between the fan 13 and a nacelle 14 surrounding the core cowl 15 and cooling an engine oil used in the engine main body 30; and a pre-cooler 40 serving as a heat exchanger using the fan stream as the heating source and cooling bleed air from the engine main body 12. Each of the engine cooler 30 and the pre-cooler 40 is arranged at a front or rear position in one portion in a circumferential direction of the nacelle 14, and the engine oil cooler 30 is located in front of the pre-cooler 40.</p> |
