Current and Proposed Designs
The Millennium Airship Corporation has Patented their ITAMMS thrust management system and are currently developing a heavy hybrid lift system.
Hybrid Air Vehicles has the first of three HAV 304's under final construction in the USA. First flight is scheduled for later this year as part of the 517 million dollar US Army LEMV program. Surveillance, remote control and ground station equipment will be supplied by HAV's partner Northrop Grumman. In addition Hybrid Air Vehicles has signed a provisional contract with Canada's Discovery Air to build up to 45 HAV's for oil, gas and mining operations in Northern Canada. The contract, which the companies hope to have finalised by 2012, is potently worth $3.3 billion with each airship costing $40 million and the first delivery expected in 2014.
"In 2008, Boeing announced it was teaming up with SkyHook to develop a heavy duty lifting vehicle. Part blimp, part helicopter, the SkyHook JHL-40 aircraft is capable of transporting a 40-ton sling load up to 200 miles."
An Australian based company is working on a project to develop an air crane called the SkyLifter a "vertical pick-up and delivery aircraft" being capable of lifting up to 150 tons.
"Northrop Grumman has been awarded a US$517 million contract to develop the massive airship and present it for military assessment in just 18 months. The company is developing the LEMV to plug straight into the Army's existing ground command centers and will provide flight and ground control operations. According to the company release, the LEMV will "operate within national and international airspace" from "austere operating locations using beyond-line-of-sight command and control."
"For heavier payloads, hydrogen-fuelled high-altitude UAVs are a possibility. AeroVironment is close to flying its Global Observer, which is designed to carry a 400-lb. payload to 60,000 ft. for seven days. Boeing plans to fly its Phantom Eye demonstrator in January 2011, with the goal of staying aloft for up to 100 hr. to demonstrate technology for a hydrogen-fueled UAV that would operate for 10 days with a 1,000-lb. payload, and seven days with 2,000 lb."
A Canadian start-up, Solar Ship Inc, is developing solar powered hybrid airships that can run on solar power alone. The idea is to create a viable platform that can travel anywhere in the world delivering cold medical supplies and other necessitates to locations in Africa and Northern Canada without needing any kind of fuel or infrastructure. The hope is that technology developments in solar cells and the large surface area provided by the hybrid airship are enough to make a practical solar powered aircraft. Some key features of the Solarship are that it can fly on aerodynamic lift alone without any lifting gas, and the solar cells along with the large volume of the envelope allow the hybrid airship to be reconfigured into a mobile shelter that can recharge batteries and other equipment.

Famous quotes containing the words current, proposed and/or designs:
“A reaction: a boat which is going against the current but which does not prevent the river from flowing on.”
—Victor Hugo (1802–1885)
“It looks as if we may be presented with a kind of vast municipal fire station.... What is proposed is like a monstrous carbuncle on the face of a much loved and elegant friend.”
—Charles, Prince Of Wales (b. 1948)
“He began therefore to invest the fortress of my heart by a circumvallation of distant bows and respectful looks; he then entrenched his forces in the deep caution of never uttering an unguarded word or syllable. His designs being yet covered, he played off from several quarters a large battery of compliments. But here he found a repulse from the enemy by an absolute rejection of such fulsome praise, and this forced him back again close into his former trenches.”
—Sarah Fielding (1710–1768)
