A few weeks ago I blogged about Solar Impulse and speculated about the possibility of radically more sustainable air flight based on lighter than air airships. Little did I realise at the time that such craft were actually being developed and were pretty much ready to go. A few days ago the Airlander 10 took its maiden voyage over a field in Bedfordshire. This Airlander 10 is very impressive. It is huge: 92 m long and 43.5 m wide, a vast helium balloon encased in high-tech Vectran material. It is has been designed and built by Hybrid Air Vehicles and is a true hybrid, its lighter than air main body is like an Airship, its aerodynamic body and small fixed wings are more like an airplane and its multidirectional engines give it much of the functionality of a helicopter. It can land anywhere, on water, in fields, in deserts or on ice-sheets. This will give it tremendous advantages in delivering goods or people to remote locations, and also opens the possibility for smaller quieter city airports. It can travel at up to 100 mph and stay airborne for weeks at a time. The Airlander 10 comes with a £25 m price-tag, very much cheaper than an Airbus A380 at £287m. They expect to have one hundred of these craft operating within 5 years. The Airlander 10 can carry a payload of 10 tonnes, and plans are afoot to build an Airlander 50 to carry 50 tonnes, with much larger future possibilities, of anything up to 1000 tonne versions.
The Airlander already creates less environmental damage than other planes, but this might well be further improved by incorporating solar cells and batteries as pioneered by Solar Impulse. I wonder whether the two teams have been in touch, it might be of great mutual benefit. Together they hint towards a future with very much more sustainable air travel. Bring it on!
