FLIGHT VEHICLE
Document Type and Number:
Japanese Patent JP2019001308
Kind Code:
A
Abstract:
To obtain a flight vehicle which has a high safety and a large cost merit.SOLUTION: This flight body comprises: two or more rotor units 30 having propellers 31 for propulsion; a frame 20 on which the two or more rotor units 30 are installed; and two or more balloons 10 which is fitted to the frame 20 in a state that the balloon is expanded by encapsulation of gas therein. Consequently, a bonding structure of each balloon 10 is simple and reduced in a cost. Even if one balloon 10 is damaged, buoyance can be maintained by remaining balloons 10 which are not damaged, and therefore, breakage of the flight body 1 due to impact of falling thereof can be prevented, and it is less risk that the flight body is brought into contact with another thing and damages it. Further, if only the damaged balloon 10 is exchanged, the flight body can be recovered to an original state. The gas encapsulated in the balloons 10, which are not damaged, is not wasted. Further, the whole of the flight body 1 can be formed into a robust structure comprising a framework of the frame 20.SELECTED DRAWING: Figure 1
