New details on the Airlander 10, one of the world’s largest aircraft, reveal a spacious cabin with floor-to-ceiling windows (and ample foot space) in an airship-like look. .. And future aircraft will be very good for the environment.
The British company Hybrid Air Vehicles recently unveiled a conceptual image of the next airship, which is 299 feet (91 meters) long and 112 feet (34 meters) wide and can accommodate about 100 people. But instead of being packed like sardines, passengers are treated with floor-to-ceiling windows and the kind of space and foot space that commercial airlines currently reserve for business class customers. Sardines.
The company plans to launch the service by 2025, which will soon challenge traditional jets on many common short-haul routes, thanks to improved comfort and 90% reductions in emissions. thinking about.
“The biggest benefit is reducing carbon dioxide emissions while traveling by a factor of 10,” Mike Durham, chief technology officer of Hybrid Air Vehicles, told Live Science. “But you’ll be in the air a little longer than if you’re on an airplane, but the quality of your trip will be much better.”
Airlanders are far more environmentally friendly than airliners, Durham said. helium To raise it in the air. In contrast, an airplane needs to generate significant forward thrust in its engine before its wings provide lift and float into the air.
After flight, the airship is propelled using four propellers at each corner of the aircraft. In the first generation, two of these propellers are driven by kerosene-burning engines, while the other two are driven by electric motors, further reducing vehicle power. Carbon dioxide emissionsBy 2030, the company plans to offer a fully electric version of Airlander.
Instead of traditional batteries, liquid hydrogen fuel cells power the Airlander’s electric motors. Liquid hydrogen can store much more energy than a battery at a constant weight, Durham said. Hydrogen is stored in the hull’s cryogenic tank and sent to a fuel cell, where it reacts with oxygen to generate electricity.
However, there are some trade-offs in airship design. For one thing, its top speed is around 80 mph (130 km / h), typically on average close to 60 mph (100 km / h). It’s closer to a car or train than a short-range jet cruising at speeds above 450 mph (720 km / h).
According to Durham, on an intercity trip of 100 to 250 miles (160 to 400 kilometers), airships can land in much smaller spaces and bodies of water, slightly slowing travel from the center of the city to another. only.
For example, the company estimates that traveling between Seattle and Vancouver takes just over three hours by plane, compared to just over four hours by Airlander. Importantly, it produces only £ 10. Carbon dioxide (4.6 kilograms) per passenger during the trip, compared to 117 pounds. (53kg) Conventional machine.
However, given that it takes only 2.5 hours to travel by car, passengers are more likely to be fascinated by the comfort of the aircraft than the speed. In that respect, Durham is convinced that the Airlander will be a much more comfortable experience than the other options. The cabin is a small part of the entire cross section of the vehicle and therefore has little effect on drag. In short, the company was able to make the airship much wider than previous streamlined jets.
Floor-to-ceiling windows combined with cruising altitudes of less than 10,000 feet (3,040 meters) provide passengers with spectacular views. Also, a huge helium-filled hull separates the engine from the cabin, so there is little vibration and little noise. Aircraft are also largely unaffected by eddy.
“Once you start climbing, you’re running in an almost silent flight environment,” Durham said.
