FILLER GAS FOR BALLOON AND DRONE WITH BUILT-IN BALLOON

摘要

To provide a drone that has a built-in balloon inside the drone and uses the buoyant force to fly the drone up in the air where the air is thin.SOLUTION: A drone 1 includes: a shrunk built-in balloon 2; and a balloon filler gas cylinder 3 for inflating the balloon by opening a gas-filling valve 4 to support buoyant force of the drone when intending to bring the drone to a higher altitude. When causing the drone to descend, opening a gas-releasing valve 5 discharges a gas filled in the balloon. Opening the gas-filling valve 4 can prevent falling in emergency.SELECTED DRAWING: Figure 1
