The present invention relates generally to worldwide airborne freight transport and surveillance systems, and more specifically to a self-sustaining drone aircraft freight and observation system that also provides a fuel source and electrical power source.
Freight delivery is a worldwide need. Humans or animals on board these systems require a narrow range of controlled temperatures and barometric pressures, not to mention food, drink, attendants, bathroom facilities, and the like. Passenger jets that carry passengers and animal cargo require very high insurance rates.
Moreover, on-board personnel required to run these passenger jets increase the operating costs of the carrier. The expense and insurance balloons when considering remote hub locations to service a population that is removed from familiar, established coastal and trade routes.
Typical manned air freight transportation systems and manned aerial observation systems are cost prohibitive in the aforementioned venues. Remote area airborne support operations often necessitate that the aircraft perform under extreme environmental conditions such as very short take-off and landing strips, restricted refueling capability, restricted ground support power facilities, and the like.
It would be desirable to have aircraft with the capability of delivering cargo from a specified remote hub that has self-sufficient servicing means. But then that limits the venues in which such a freight carrier and aerial observation system can operate. Such an airborne freight carrier should be able to transport up to a predetermined poundage of cargo and stay in the air for a predetermined amount of time, e.g., 20 hours. Remote field operations should be as autonomous as practicable. Command and control systems should be automated.
Notwithstanding the expansion of e-commerce, products must still be transported, and at some point in the product fulfillment phase, especially with respect to hard-to-reach locations, the products are likely to have been transported via airborne transport to the purchaser.
The much sought after ‘holy grail’ of airborne transport systems is to provide a system that substantially increases remote access in a cost effective manner. Notwithstanding current airborne transport and surveillance systems, there remains a need for an airborne transport and surveillance system that can serve remote population centers throughout the world.
Thus, a self-sustaining drone aircraft freight and observation system solving the aforementioned problems is desired.
The self-sustaining drone aircraft freight and observation system includes a fleet of jet-powered drone aircraft that are designed to carry freight only. The drones operate from a separate airfield in outlying areas to decrease land costs and to avoid disturbing residential and business areas. Without humans or animals on board, there is no need for controlled temperatures, food, drink, attendants or bathroom facilities. Insurance rates are greatly reduced. Navigation is automated using guidance from OPS satellites, and the aircraft can be launched by a catapult, such as those used on aircraft carriers during takeoff to reduce the fuel payload.
The freight drone system component can profitably operate in parts of the world where populations are dense, but the financial levels of the population are not attractive for established air freight companies and their existing transport methodology. The availability of affordable air freight service can be a major opportunity for the populations in those areas.
For example, in China, where the population living close to the oceans has developed economically to a greater degree than those living in the inland areas, it would be economically advantageous to utilize the transportation component to service the sparsely populated inland areas. The same thing is true in areas of India, Africa, Asia, distant areas of Russia, more remote areas of North, Central, and South Americas, as well as New Zealand, Australia, and the like.
The transportation component of the system can be combined with an observation component, and with the combination of a large scale energy production center and multi-acre vegetable, herb and flower production center. The observation component allows the drone to observe and report on weather conditions, emergency signals from boats, ships or other sources where help is needed.
Electric power for the airport area may be supplied or supplemented by arrays of solar panels. The solar panels are on stilts and may form a roof of a greenhouse where plants can be grown. Electrical energy produced by the solar panels may be used to split water molecules into hydrogen and oxygen using an electrolysis plant. Water for the plants and hydrogen and oxygen production is supplied by wells. The hydrogen may further be used to produce electricity in fuel cells, while the oxygen can be stored in tanks and sold. Excess electricity is stored in batteries. The batteries can be trucked to a remote site for use of the electricity stored therein, and returned to the site of the system via access roads for recharging. Thus, the system does not need to be connected to the public utility electrical grid.
These and other features of the present invention will become readily apparent upon further review of the following specification and drawings.
Similar reference characters denote corresponding features consistently throughout the attached drawings.
As shown in
Navigation is automated using guidance from GPS satellites (16) in communication with the navigation unit (80) of the aircraft (10). Where necessary, the aircraft (10) can be assisted during takeoff by the use of a hydraulic catapult (13) to reduce the fuel payload, or, alternatively, the craft (10) could be towed to approximately 45,000 feet and launched therefrom by a tow plane. The transportation component of the system (5) can be combined with an observation component (18) and a large-scale energy production center comprising solar panels (30), a hydrogen plant (55), fuel cells (38), oxygen storage tanks (40) and batteries (44) in conjunction with a multi-acre vegetable, fruit, herb and flower production center (26). The observation component (18) includes sensors that can observe weather conditions and emergency signals from boats, ships and other sources.
The solar panels (30) of the energy production center are preferably mounted on stilts (32). However, the solar panels (30) may also be disposed on the roof (7) of a greenhouse (34) of the multi-acre vegetable, herb and flower production center (26) where the plants and herbs are grown. Electrical energy produced by the solar panels (30) may be used to power a hydrogen generator (55) where water molecules are split into hydrogen and oxygen for use as a fuel supply. The hydrogen may further be used to produce electricity in fuel cells (38), while the oxygen can be stored in tanks (40) and sold.
Water for the plants and hydrogen and oxygen production is supplied by wells (42), shown in the block diagram of
It is to be understood that the present invention is not limited to the embodiment described above, but encompasses any and all embodiments within the scope of the following claims.
