The new age of the airship: Could blimps be the future of air travel?
Sleek, green and coming to the skies above you.
What if you could fly with a fraction of the carbon emissions of a conventional aeroplane? What if you could cruise through the clouds with almost zero noise? And, what if you could board your aircraft without first having to navigate a sprawling airport and all its associated infrastructure?
That’s the elevator pitch for a new generation of airships, the retro-futuristic, blimp-style vehicles that might just revolutionise air travel in the coming decade. Dotted around the world, companies from small start-ups to aerospace giant Lockheed Martin are building lighter-than-air, modern-day Zeppelins with a broad range of applications in mind.
One British company, Hybrid Air Vehicles (HAV), recently laid out plans for a series of short-haul flights that would enable city-hopping trips aboard its Airlander 10 craft. Proposed routes include Liverpool to Belfast, Oslo to Stockholm and Barcelona to Palma. And per passenger, HAV claims the carbon footprint of such a flight would be less than a tenth of the same journey in a conventional jet plane, because helium is used as a lifting gas to get the craft airborne.
“Three quarters of the carbon reduction almost comes for free,” says Mike Durham, HAV’s chief technical officer. “It’s helium keeping us up so we only need fuel [from four combustion engines] to push us along. Conventional aeroplanes need to burn fuel to stay up as well.”
