Is this whale-shaped plane the future of airliners?

Airliners have become steadily bigger in an effort to take fit in more passengers and drive down the cost of tickets. Could a new outsized design change the way we fly?
Spotting an Airbus A380 at an airport can still create great excitement. The giant, double-decker plane can seat between 500 and 850 people, depending on how much space is given to space-saving economy class, and how much goes to higher-paying passengers with all that extra leg room. It’s an aviation giant, the biggest passenger-carrying aircraft ever to fly the skies.
“Travelling in the Sky Whale could be like a travelling in your private ‘theatre seat’, enjoying what happens around you; hearing some air flow noise, but feeling safe inside a big and intelligent structure,” Vinals says.
The design would use advanced technologies such as self-repairing wings, swiveling engines to enable a near vertical take-off, and hybrid propulsion.
“The engines and batteries are fed by a turbine inside the wings, like a high-speed and powerful dynamo,” says Vinals.
The design also calls for a system to redirect air flow to intake engines and to control laminar flow – in other words, to reduce turbulence around the plane and reduce drag.
None of these technologies are feasible on a large scale at the moment, but all are possible, says Vinals.
“I did this because I am an aerospace and aviation enthusiast – the technology, development and evolution,” he explains. “I would like to contribute, with my vision, about these.”
Perhaps that vision from someone outside the aerospace industry, without preconceptions, is what is needed to revolutionise plane design. Vinals told me he did “years” and “terabytes” of research. It’s an approach that some in the field appreciate.
For a manufacturer to be able to sell a new aircraft, it has to demonstrate that it is safe. The safety regulations have evolved over a century of manned flight, but with a radical design it would be much harder to demonstrate safety.
“The optimised airplane is like a grand set of compromises, and it’s a colossal exercise to balance everything,” says Drela.
“Airbus went with the huge A380, Boeing put its money on the smaller airplane with 787. And it is not obvious which is the better approach yet.”
But, Vinals says, Albert Einstein might have the last word on this: “Your imagination is your preview of life’s coming attractions”.
