Abstract:
PROBLEM TO BE SOLVED: To provide a means for preventing uncontrolled flight or tip-over of an unmanned aerial vehicle (UAV) during take-off. SOLUTION: The UAV includes: a step 302 for receiving a measurement representative of a posture of the UAV from the magnetometer, wherein the measurement is of only one axis of the three-axis magnetometer; a step 304 fpr comparing the measurement to an allowable range of posture; a step 306 for determining that the measurement is not within the allowable range of posture; and a step 308 for performing at least one corrective action for the UAV.

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).
