Airplane design could use 70 percent less fuel

Researchers at MIT say they have come up with designs for a new generation of commercial aircraft that could use as much as 70 percent less fuel than today's airliners.

As part of a $2.1 million NASA grant, the MIT-led team said that its designs for a so-called "N+3" airplane--meaning three generations beyond today's airplanes--could leverage new technologies like advanced airframe configurations and propulsion systems and could deliver the 70 percent fuel savings by around 2035.

In a release, Ed Greitzer, an aeronautics and astronautics professor at MIT, said that meeting NASA's criteria for new, highly-efficient aircraft designs would require a "radical change" from the current aviation paradigm. That's mainly because airplanes largely have the same design today as they've had for the last 50 years--an "easily recognizable 'tube and wing' structure of an aircraft's wings and fuselage."

But Greitzer's team crafted two designs that could upend the traditional airplane paradigm. One is a 180-passenger D "double bubble" series, which could eventually replace the Boeing 737 that is used for so much domestic travel; and the 350-passenger H "hybrid wing body" series, which could take the place of the popular Boeing 777 used for many international flights. … Read more

Boeing's 787 meets its oldest ancestor, on high

When the new kid on the block meets the grizzled old veteran, it can be a beautiful sight to see.

On May 8, in a promotional moment worthy of its setting, Boeing's newest airplane, the 787 Dreamliner, briefly met up in the skies over Washington State's Mount Rainier with the company's first-ever commercial production aircraft, the Model 40.

As seen in the image above, the rendezvous was a serious moment of old meets new. But for Boeing, the chance to put the two planes together in the sky was all about taking a quick moment from months … Read more

Turbine-electric hybrid VTOL attack drone flies again

The Excalibur, a new turbine-electric hybrid propelled VTOL (vertical takeoff and landing) unmanned attack drone, has successfully completed another test flight after taking on two new onboard computers last week.

Developed by Aurora Flight Sciences Corp. for the U.S. Army Aviation Applied Technology Directorate and the Office of Naval Research, the Excalibur is another radical robo-craft concept vying to fill the military's burgeoning demand for specialized UAVs.

The demonstrator model, weighing in at 700 pounds, can hit 520 mph, making it one of the fastest drones around, according to the Aurora. The nearly autonomous flight control system allows … Read more

iPhone apps for airline geeks

If you haven't figured this out already, I'm a serious airline geek. Yes, I'm the kind of person who keeps track of all his flights and I can identify planes as they taxi by at the airport. Want to know which airlines flies nonstop between San Francisco and Sydney? Well, I can tell you (United and Qantas). Some would call it an obsession, but I think that it's just an interest.

If you're like me, you'll be delighted to know that the iPhone App store has quite a few options to indulge your passion. Without ever leaving your iPhone, you can check for delays, find the best seat on your flight, learn facts about your aircraft, and find your departure gate at the airport.

The following is a list of apps that I've used on CNET's iPhone. When I'm not using them just for fun--like I said, it's an interest--they have come in handy quite a few times. The titles that I've highlighted below aren't the only such apps available, but they are the ones that I've used. If you have other picks, be sure to tell me about them below.

Airport Status 99 cents

This app won't show delays for specific flights, but it will show general delays affecting U.S. airports. This is especially useful when your home airport is San Francisco International--due to low clouds it often suffers from "ground stops" where flights are held at their departure airport until the weather improves. Newark Liberty is another airport that's constantly on here. New Yorkers and Jerseyites, take note.… Read more

Airlines see green upside to economic downturn

Biofuels are on the way up, while carbon emissions are on the way down, a global airline industry spokesman said Tuesday at the annual Aviation and Environment Summit in Geneva.

After a successful run of pilot programs from Continental, Virgin, Air New Zealand, and JAL, sustainable biofuels are on track to be approved by the International Air Transport Association (IATA) for wide commercial use in planes by 2010 or 2011, Giovanni Bisignani, director general of the IATA, said in a speech given at the summit.

The IATA includes more than 230 airlines that make up about 93 percent of the … Read more

Guest post: Aviation ready to take off with biofuel

Note: This is a guest post. CNET News occasionally runs such pieces.

One of the compelling and challenging aspects of the current focus on alternative energy is the amazing array of technologies that are in various stages of development. Should a country, company, or individual investor place a bet on wind or solar? Batteries or fuel cells? Nuclear, anyone?

The trade-offs are endless. In the case of aviation, our path is somewhat clearer. There is no substitute for kerosene. Its physical and chemical properties have been optimized over 100 years to provide the best possible combination of energy content, density, … Read more

Why the flying car may be too much for humanity

The founders of a company called Terrafugia are undoubtedly very, very clever.

All graduates of the Massachusetts Institute of Technology, they formed the company four years ago with the aim of creating The Transition, a car that flies--not merely in the speed sense of "flies," but rather in the "takes off and does things planes do" sense.

The initial flight is planned for the end of this month or some time in February at an airport in upstate New York.

I am worried, not so much because I am suspicious of flying but because I am … Read more

The Mile High Bed: Yeah, baby!

"Join the mile-high club without the hassle of going to the airport," MotoArt says of its new Mile High Bed, which, like all of the company's products, is created from aircraft inventory.

At $35,000 (and no, those pretty flowers on the bedstand aren't included), this mod piece of furniture had better lift you to new altitudes of um, comfort and style. You could, after all, get a two-seat Cessna 152 for less. And seriously, if you're that intent on joining that proverbial action-in-the-sky club, might we suggest you just snag a couple of Southwest … Read more

Delta testing cell phone-based airline check-in

If you're flying Delta Air Lines out of New York's LaGuardia Airport, you can now flash your cell phone to get onboard. On Tuesday, the airline rolled out a partnership with the Transportation Security Administration (TSA) to test out a "paperless check-in"--passengers download a boarding pass onto their cell phones and have it scanned by the TSA at the airport's security checkpoint as well as when they board the plane.

Fellow domestic carrier Continental is already testing a similar program.

The speedier check-in is limited to cell phone customers who can access the mobile … Read more

What happens in Vegas winds up on the Web

In the tech community, Las Vegas has somewhat of a bad rap. Sin City, after all, is home to so many large-scale industry trade shows (case in point: CES) that just mentioning the name is bound to induce a headache, and not in the I-got-plastered-and-lost-all-my-money sense.

The guys at Thrillist, the e-mail newsletter for 20- and 30-something dudes, may have changed that a bit. To celebrate their recent launch of a Vegas-centric newsletter (joining New York, Boston, Los Angeles, San Francisco, and soon Miami), as well as the fact that trendy airline JetBlue is one of their biggest sponsors, founders … Read more
