NASA Reveals the Weird and Wonderful Commercial Airliners of 2025

NASA's contracted three of the biggest names in aircraft design to dream up the kind of airliner we'll see in 2025, and has just shown the initial concepts. They're weird, eco-friendly, and wonderful.

NASA's goal is to invent commercial airliners that can cover the same kind of use cases as current aircraft, but do so with far greater fuel efficiency, less gaseous and noise pollution, and potentially eating up less energy and resources during their fabrication too. This is the sort of long term aeronautical experimentation that NASA funds from time to time, spurring companies to look into long term evolutionary concepts rather than incremental R&D in their usual business areas.

Late in 2010 it contracted Lockheed Martin, Northrop Grumman and Boeing to imagine an aircraft that could fly as soon as 2025, manage 80% of the speed of sound, with a range of 7,000 miles and a payload of 50,000 to 100,000 pounds--either passengers or cargo. Given how long it usually takes to craft an aircraft from scratch, and bearing in mind how many technical hitches the revolutionary Boeing 787 Dreamliner has suffered, these are the sorts of aircraft that these three firms are probably beginning to design for real right about now. Airbus, the European competitor to these U.S. businesses, has already dreamed up a design for 2050, for example.

Boeing

Boeing's design (shown above) is the most familiar from this crop. It looks like it's an evolution of earlier Boeing concepts and even test vehicles. It's a part-winged, part lifting-body vehicle, with huge internal volume for carrying hundreds of passengers or many tons of cargo, and it has engines mounted on top of the rear body flap so that their noise is much better shielded from the ground. These engines are either conventional turbofans (presumably with efficiency and noise-suppression tech evolved from that used on the Boeing Dreamliner) or the kind of experimental turbo-screw that's currently a hot-topic research field due to its improved fuel efficiency. 

Boeing has many decades of research to draw upon, but will have to persuade passengers to enjoy flying inside a huge room with no windows.

Northrop Grumman

NG has initially gone for a dual-fuselage concept, something that's been contemplated for some time. The idea is that you can produce a much larger cargo volume using more conventional aircraft designs, and that the engines are partly shielded by the twin bodies which will contain noise pollution better. It has the advantage of allowing passengers to have windows, and could allow for mixed-mode uses with part-cargo, part-passenger flights. The design isn't even that unexpected, if you consider the White Knight carrier aircraft that'll be lofting Virgin's SpaceShipTwo into space.

Lockheed Martin

Lockheed's concept is the most aesthetically attractive of the three. It's a development of current aircraft body design, but incorporates unusual aerodynamic advances in the vehicle's wing and engine. The wings look for the most part like a Dreamliner's wing and blended vertical winglet, but the winglet extends upwards and folds back in a loop to connect to the aircraft's tail--this increases the area available for lift. The aircraft has a single giant engine, which will require significant reliability improvements over current turbofan design, but its placement in the tail of the aircraft means it pushes along the centerline and could radiate less noise downward to the ground.

The three concepts will evolve throughout this year as the companies concerned develop and research each project, but there's one thing we can say straightaway: Beautiful, aren't they? 

Updated: An earlier version of this article contained a typo saying that new aircraft would fly at 8% of the speed of sound instead of 80%. Thanks to all the commenters who caught this one.

    did anybody else notice that 8% of sound is only 60 miles an hour? perhaps i'll just drive in 2025

  • Mike Kelley

    These are cool, but if the 787 Dreamliner is any indication, the odds that we'll see any of these in use by 2025 are about 1 in 32,416.

    Impressive... 8% of the speed of sound?

    That's 60 mph.....

    Try 80% (ie .8 Mach, typical airliner speed)

    Cheers

    Just a typo, I'm sure, but 8% of the speed of sound can be done on the highway. I think Kit probably meant 80%, which is a typical jet cruising speed. We call it Mach .80.

    Much as I respect Lockheed, I don't see a single-engine airliner happening anytime soon, but a blended-winglet-tail connection is something I could definitely see becoming popular.

    I hope the airlines somehow manage to convince people that flying (safely) is inherently more costly than they want to believe, so that new aircraft like these, profitability, and stability can return to the industry. It's been a long ten years since 9/11 for the employees in this business, and while nearly all costs are either regulated or inflationary, if not both, passengers insist that revenue (fares and fees) must be market-driven. Reliability and service, if not safety itself, are being sacrificed to bridge the financial chasm between regulated costs and deregulation revenues, and nothing will improve until that changes.

    Kit,
    I believe 8% the speed of sound is only about 60 mph. You must have meant 80% the speed of sound?
