Siemens introduced the world this week to the first serial hybrid electric aircraft at the 2011 Paris Air Show in Le Bourget, France.

The DA36 E-Star, a two-seater composite glider, was a partnership project among Siemens, aircraft manufacturer Diamond Aircraft Industries, and aerospace giant EADS. The plane is based on Diamond Aircraft's HK36 Super Dimona.

Similar to General Motors' Chevy Volt drive train, the DA36 E-Star uses a serial hybrid electric drive train in which a main engine is powered alternately by a gasoline-powered generator and batteries.

A 70-kilowatt Siemens engine runs the aircraft's propeller. That engine is powered alternately between a small Wankel combustion engine made by Austro Engine that runs on gasoline and acts as a generator, and EADS batteries. Additional EADS batteries are used during takeoff and ascent.

While it's in early development, Siemens claims its drive train can be scaled up for use on a large passenger plane, and under further development hopes to create a drive train that can save 25 percent in fuel consumption.

Of course, even more so than with electric cars, battery weight is still an issue. The plane's range is limited by the number of batteries and the amount of fuel it can carry.… Read more

The decade-long war is over: EADS North America has conceded defeat to Boeing in the campaign to capture a multibillion-dollar deal to build a new aerial tanker for the U.S. Air Force.

Last week, the Pentagon announced that it had selected Boeing to build the next-generation KC-46A tanker in a long-term arrangement that could eventually be worth $30 billion. For starters, the Chicago-based aerospace titan is getting $3.5 billion to build the first four of a projected 179 of the new tankers. It has to deliver 18 by 2017.

Aerospace giant European Aeronautic Defence and Space has introduced a "hacker-proof" encryption technology that it claims will revolutionize Internet security and bring "cryptography into the 21st century."

The system, called "Ectocryp," was developed for military and business applications by researchers and engineers at EADS' Defence and Security Systems division in Newport, South Wales. The team relied on technology developed by the U.K.'s Government Communications Headquarters, sister agency to the NSA and formerly known as Government Code and Cypher School, of German Enigma fame.

The system owes its success to the "lightning … Read more

There have been several stories in the news this week about airplanes and spacecraft. I'm an Air Force veteran myself, and I've been an Aviation Week subscriber for over 20 years, but you don't have to be in the industry to keep up with the latest in aerospace technology. Even CNET covers this kind of thing today, and some of the stories I've seen this week have gotten me thinking about buying a private jet.

I think Esther Dyson deserves a lot of credit for bridging the computer and aerospace industries. In 2005, Esther inaugurated her … Read more

Good news, galactic explorers: You no longer have to pay a million bucks for the privilege to be one of the only civilians to fly in outer space--just somewhere between $200,000 and $300,000.

Europe's EADS Astrium is developing a space jet to take off in 2012 that's one of a new generation of "airplane-to rocket" vehicles, according to BornRich: It looks like a conventional aircraft but is powered by rocket engines. The "Astrium Space Jet" can even take off from regular airports, though we somehow doubt that it will go through the … Read more
