Abstract
A lighter-than-air toy drone assembly that stays aloft using a balloon that is filled with a lighter-than-air gas. The balloon is inflated and deflated with the gas through a remote control vent valve. A ballast chamber can be provided that is filled with and drained of ballast through a purge valve. Controlled flight is achieved by selectively controlling motorized propellers, the vent valve and the optional purge valve. The motorized propeller provides horizontal movement. The purge valve and the vent valve change the buoyancy of the drone assembly and therefore control vertical movement.
Claims18
A lighter-than-air toy drone assembly comprising:
- a balloon that is inflated and deflated through a vent valve;
- an airframe coupled to said balloon;
- a ballast chamber supported by said airframe, wherein said ballast chamber is filled and drained through a purge valve;
- a battery supported by said airframe;
- at least one motorized propeller coupled to said airframe, wherein said at least one motorized propeller is powered by said battery and is capable of moving said toy drone assembly horizontally in flight;
- a controller supported by said airframe for selectively controlling said at least one motorized propeller, said purge valve, and said vent valve.
A lighter-than-air toy drone assembly comprising:
- a balloon filled with a volume of lighter-than-air gas;
- a vent valve for selectively venting said lighter-than-air gas from said balloon;
- an airframe coupled to said balloon;
- at least one motorized propeller coupled to said airframe for moving said air drone assembly horizontally in flight;
- a ballast chamber supported by said airframe, wherein said ballast chamber holds a volume of ballast;
- a purge valve for selectively releasing some of said volume of ballast from said ballast chamber;
- wherein said vent valve, said purge valve and said at least one motorized propeller are remotely controlled through a personal area network generated by a remote smart phone.
A lighter-than-air toy drone assembly comprising:
- a balloon that is inflated and deflated through a vent valve;
- an airframe coupled to said balloon;
- a battery supported by said airframe;
- at least one motorized propeller coupled to said airframe, wherein said at least one motorized propeller is powered by said battery and is capable of moving said toy drone assembly horizontally in flight;
- a controller supported by said airframe for selectively controlling said at least one motorized propeller and said vent valve, wherein said controller automatically opens said vent valve and deflates said balloon when said toy drone assembly flies outside a personal area network generated by a remote smart phone.
