cylonlover writes "The dirigible airship, the oddball aircraft of another era, is making a comeback. California-based Aeros Corporation has created a prototype of its new breed of variable buoyancy aircraft and expects the vehicle to be finished before the end of 2012. With its new cargo handling technology, minimum fuel consumption, vertical take-off and landing features and point to point delivery, the Aeroscraft platform promises to revolutionize airship technology. The Aeroscraft ship uses a suite of new mechanical and aerospace technologies. It operates off a buoyancy management system which controls and adjusts the buoyancy of the vehicle, making it light or heavy for any stages of ground and flight operation. Automatic flight control systems give it equilibrium in all flight modes and allow it to adjust helium pressurized envelopes depending on the buoyancy requirements. It just needs one pilot and has an internal ballast control system, which allows it to offload cargo, without using ballast. Built with a rigid structure, the Aeroscraft can control lift at all stages with its Vertical Takeoff and Landing (VTOL) capabilities and carry maximum payload while in hover. What makes it different from other cargo vehicles is that it does not need a runway or ground infrastructure."
