Abstract:
PROBLEM TO BE SOLVED: To provide an aerial photographing device by a radio control helicopter, capable of precisely imaging an object even in a state of severely restricting a hovering attitude of the radio control helicopter such as the direction of a machine body and an inclination of a rotary surface of a rotor blade by the wind direction in bad weather just after, for example, a typhoon. SOLUTION: This aerial photographing device of a disaster-stricken, damaged and deteriorated state of a facility such as for a lifeline, is provided for mounting a control device PC, an imaging device, a GPS antenna, a radiocommunication device, a battery and a gyroscope for remotely operating at least the helicopter on the radio control helicopter, and is provided with a skid freely rotatable by 360° around the axis of the perpendicular and vertical direction (the Z axis) to the flying direction (the X axis) of the radio control helicopter, and an arranging pedestal of the imaging device mounted on the skid and freely rotatable around the axis in the perpendicular and horizontal direction (the Y axis) to the X axis.

PROBLEM TO BE SOLVED: To provide a vibration control suspension device for a helicopter, provided with a simple structure reducing vibration with respect to a measuring instrument for surveying or a camera mounted on an industrial unmanned helicopter during flight, and improved in accuracy of survey data. SOLUTION: The device is provided with: machine body connecting frames 12A and 12B detachably attached to a machine body of the helicopter; and mounted object supporting frames 14A and 14B. An insulator 28 for absorbing and damping vertical vibration is disposed on the machine body connecting frames 12A and 12B, the mounted object supporting frames 14A and 14B are attached in a direction to compress the insulator 28 from the upper part, and the mounted object supporting frames 14A and 14B, are attached to the machine body connecting frames 12A and 12B in such a manner of holding the insulator 28 therebetween.

PROBLEM TO BE SOLVED: To provide a chemical spraying device for an unmanned helicopter, enabling to avoid the breakage of a chemical spraying part even if booms collide on a ground surface when the helicopter is flied down and grounded. SOLUTION: The chemical spraying device 105 for the unmanned helicopter 1 includes atomizers 62L, 62R for spraying chemicals, and the booms 54L, 54R protruded to the outside of a machine body for the atomizers 62L, 62R to be mounted thereon. The booms 54L, 54R have turning angle adjusting parts 158L, 158R on the base sides, respectively, and it can be turned to the upward direction of the machine body. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a method and an apparatus for supporting control on an unmanned radio-controlled helicopter. SOLUTION: The control support device including a microcomputer, a PWM signal reading circuit, a PWM signal generating circuit and a PWM signal switching circuit is inserted into between the existing receiver of the unmanned radio-controlled helicopter and a servo motor. When control is performed by an operator, the control is overridden to control the servo motor as usual or the controlled amount is interpreted as a targeted value to conduct the following-up control. When the control is not performed by the operator, horizontal control is automatically maintained and the previously designated bearing and altitude are maintained, thereby supporting the control in performing operations such as aerial photography.

Abstract:
PROBLEM TO BE SOLVED: To provide a landing device for a movement body capable of sufficiently relaxing landing impact load applied to a body part while including a case where a direction of the landing impact load is coincident with an axial direction of a support leg. SOLUTION: When the landing impact load is applied to a skid 3 accompanying with landing of a helicopter, respective support legs 2 are contracted by a component in a vertical direction of the landing impact load. At that time, a coil spring 5A of a shock absorber 5 absorbs the component in the vertical direction of the landing impact load, and vibration of the coil spring 5A is attenuated by a damper 5B. Further, the respective support legs 2 are relatively moved in a longitudinal direction relative to the skid 3 by a component in a longitudinal direction of the landing impact load. At that time, a coil spring 6A of a shock absorber 6 absorbs the component in the vertical direction of the landing impact load, and vibration of the coil spring 6A is attenuated by a damper 6B. As a result, the landing impact load applied to the body 1 of the helicopter is sufficiently relaxed while including the case where the direction of the landing impact load is coincident with the axial direction of the support leg 2.
