1. An aircraft comprising:
fuselage;
a wing body that is provided to extend laterally from the fuselage and configured to generate lift during cruise;
a boom extending in a front-back direction that is supported by the wing body to be spaced apart from the fuselage;
a rotor that is supported on the boom, the rotor having one or more blades configured to generate thrust in a vertical direction during take-off and landing;
a cooling apparatus configured to cool the rotor by using a radiator arranged within the boom; and
an airflow guide structure provided in a part of the boom and configured to guide airflow, which is generated by rotation of the one or more blades rotating around a rotational axis of the rotor, to the radiator, wherein
the airflow guide structure includes an inlet that is provided on a surface of the boom positioned below a plane of the rotation of the one or more blades, and
the inlet faces opposite to a direction of a movement of the rotating one or more blades.
