AUVSI

Thanks to Tropical Event Ernesto's having ERAU shut down early yesterday, I spent more of the afternoon than I thought I was going to be able to at the AUVSI conference in Orlando. Didn't get to take in the paper presentation part of the conference, but did get to wander through the exhibits and talk to vendors about a couple of projects involving UAV propulsion and heavy fuels (i.e., diesel) that I'm going to be working on.

Stay tuned.

David Axe's Bottom Line on the Raptor

The bottom line on David Axe's five posts at Defense Tech on the F-22?

...[S]ome critics ask, why can't we cut the expensive Raptor in favor of the cheaper Lightning? While a fine bomb-hauler and (one hopes) a good multi-service airframe, the F-35 is a mediocre performer. Said 1st Fighter Wing commander Brigadier General Burton Field, "The problem with the F-35 ... is speed. It doesn't have the capability to supercruise. Speed lets us get inside the decision cycle of the bad guy."

For the most dangerous air battles and attack missions, F-35 squadrons will rely on F-22s for support. That's an unavoidable state of affairs when you design an airframe to replace slow- and low-flying Lockheed Martin A-10 Warthogs and Boeing AV-8B Harriers as well as light and flexible F-16s and Boeing F/A-18 Hornets. The F-35 is a compromise. Potentially a very successful compromise, but still ...

We've already sunk $25 billion into Raptor development. That money is irrecoverable. Further jets cost only around $115 million (perhaps twice as much as a new F-16) and will get even cheaper. We should get a good return on our investment. A good return, in my estimation, means a full fleet of at least 381 Raptors in 10 or more full-strength squadrons. That should guarantee air dominance for another 30 years or more.

{Best, Worst}. Software. Ever.

Information Week has this article up with a list of "Greatest Software Ever Written." I won't give away the winner of the number one slot, but it starts with "Berkeley" and ends with "4.3".

On the other end of the spectrum, today's Washington Post has this article (registration or workaround required) about the FBI's Virtual Case File system, one of the larger software-development screw ups in history. Why? According to this September 2005 article in IEEE Spectrum, because they wouldn't get the requirements right, that's why.

Boeing Gives Up on In-Flight Internet

After what could best be classified as a half-hearted attempt to offer in-flight internet service, Boeing has wimped out and given up on the idea. The story's in the International Herald Tribune (link from Drudge).

In announcing the project in 2000, Boeing predicted that the market for inflight Internet access would be worth $70 billion over 10 years. But the company said Thursday that the number of passengers using the service on the 156 aircraft with 12 airlines amounted to little more than "low single digits" a flight. Boeing declined to say how much it costs to run the service.

The cost to airline passengers is $9.95 an hour or $26.95 for an entire flight, and revenue is shared between Boeing and the airlines.

Lufthansa, which operates 62 aircraft using the system, said that the maximum number of passengers ever connected at one time is around 40 a flight, usually on routes to North America and Asia.

"Given the usage level, we just didn't see the kind of numbers that add up to a business," said John Dern, a Boeing spokesman. "You could say it flew well technically, but it didn't fly so well as a business."


The upside: Like terrestial-based bandwidth, the technology is likely to be available at el-cheapo prices, giving someone else with a better business plan -- like, oh, getting a US business carrier like Delta to offer it domestically in the USA on the northeast shuttle routes and cross-country flights -- a chance to keep the idea alive.

F-22A Raptor

Wednesday, August 09, 2006

"[I]t's either like playing a video game, flying a remote-controlled plane, or doing data entry"

Slate explains how to fly a UAV (current term in the MSM: "drone"), here.
The U.S. Army's drone of choice, the Raven, is a 3-foot-long, camera-equipped miniplane that's "launched" when a soldier winds up and throws it. Once in the air, the Raven is controlled by a book-sized console that looks something like a 1980s-era Coleco football game. The screen at the top displays one of the drone's three video feeds, and the joysticks and buttons at the bottom pilot the craft. Operators can use the sticks to pilot the Raven like a model plane or just preprogram GPS coordinates for the drone to follow. There's even a button that automatically returns the Raven to its launch site.
And more on Predator and Global Hawk sized planes.
