| 20090314879 | HYBRID THERMAL AIRSHIP - An airship comprises a shell, a gas storage system, an air storage system, a cargo storage system, a heating system, and a propulsion system. The shell encompasses a volume. The gas storage system is located within the volume, wherein the gas storage system is capable of storing a lighter than air gas. The air storage system is located within the volume, wherein the air storage system is capable of storing heated air. The heating system is capable of heating air. The propulsion system is capable of propelling the shell during flight. | 12-24-2009 |
| 20100012771 | HYBRID LIFT AIR VEHICLE - A hybrid lift air vehicle for lifting and transporting a payload to a delivery location, which comprises a helium or other lighter-than-air gas filled envelope mounted on an airframe. Variable and reversible vertical thrusters are positioned on the airframe, and at least two variable and reversible lateral thrusters are mounted on the envelope or mounted on truss arms attached and extending out from the airframe, wherein, when the vehicle is connected to the payload for transport, the helium or other lighter-than-air gas supports or substantially supports the weight of the vehicle and the vertical thrusters are then continuously engaged to support the weight of the payload and to provide lift to the payload, wherein the lateral thrusters are then engaged to effect lateral movement of the vehicle to the delivery location, whereby, once at the delivery location, the lift provided by the variable and reversible vertical thrusters is reduced or reversed so as to allow the air vehicle to descend and the payload to again engage the ground surface, and where necessary, the variable and reversible vertical thrusters may be reversed to facilitate the unloading of the payload from the vehicle, the vehicle continuing to be kept aloft, once unloaded, by the helium or other lighter than air gas. In this manner, the vehicle utilizes the helium or lighter than air gas to offset or substantially offset the weight of the vehicle, the vertical thrusters providing the power to lift the payload. | 01-21-2010 |

| 20120273608 | HYBRID LIFT AIR VEHICLE - A hybrid lift air vehicle for carrying and transporting a load, comprising an envelope having a generally ellipsoidal shape adapted to receive a volume of lighter-than-air gas, at least two variable thrust vertical thrusters in secure engagement with the envelope and at least two variable thrust lateral thrusters in secure engagement with the envelope, means for temporarily securely engaging the load to the envelope wherein the volume of lighter-than-air gas has a buoyancy that offsets at least 25% of the weight of the air vehicle when unloaded, wherein the thrust from the at least two vertical thrusters may be varied to raise and lower the air vehicle and the load when engaged, and wherein the thrust from the at least two lateral thrusters may be varied to maneuver and transport the raised air vehicle and the load when engaged. | 11-01-2012 |
