Abstract:
An unmanned helicopter has a fuselage (1a) with a main body (4) and a tail body;
a main rotor (6) provided above the main body (4) and driven by an engine in the fuselage
(1a); a tail rotor placed at the rear of the tail body (5); a pair of left and right
support legs (8, 8) extended downward from lower left and lower right sections
of the main body (4); a pair of left and right skids (9) provided at lower ends of
the support legs (8, 8) and positioned, in a front view, more on the outside in the
width direction of the fuselage (1a) than the main body (4); and a radiator (71)
positioned, in a side view, more on the front side than the front edges of the skids
(9) and formed so as to extend downward from the vicinity of a bottom surface (83)
of a main body front section so that an airflow receiving surface of the radiator
is oriented in the front-rear direction of the fuselage (1a). Outer edges, in
the width direction of the fuselage (1a), of the radiator (71) are projected outward,
in the front view, from outer edges of a main body bottom surface (83) near the radiator
(71). Also, outer edges (71a) of the radiator (71) are positioned more on the inside,
in the width direction of the fuselage (1a), than the skids (9).
