Swedish Flight Simulator Adds G Forces
jonerik writes "According to this article in Aviation Week and Space Technology, Sweden's Dynamic Flight Simulator (DFS) is believed to be the first flight simulator which actually allows fighter pilots to experience G forces under simulated conditions. Designed and built by California-based Wyle Laboratories, the DFS is essentially a flight simulator capsule (in this case for Sweden's JAS 39 Gripen fighter) located at the end of a 30-foot centrifuge arm. 'We wanted to give pilots the ability to "fly" and interact with the environment rather than just be a passive [centrifuge] rider,' said Will Roberts, program manager for Wyle Laboratories' DFS programs. 'We've come a long way in being able to translate the six degrees-of-freedom you get in an aircraft into the three degrees-of-freedom that we can control in a centrifuge. It's not perfect, but we think it's pretty good. There's room for more research to make it even better.'"
...the use of a smaller drive motor. Wyle chose a 1,900-kw. Westinghouse DC motor originally designed for steel mill applications, connected directly to the centrifuge-arm drive system. It delivers about 7 megawatts of peak power in approximately 100 millisec
If that's smaller, what was the bigger one??
They should give this thing a try. Looks fun. They brought it to Detroit once and I was going to ride on it until someone puked all over.

That's a real step forward in a technological sort of a way, but why? Have we had a problem with poor standards in fighter pilot training in recent years? I have to admit that if either the US or anywhere else, including my beloved UK has had this problem I had not heard.
Seems like a lot of effort for not too much reward to me but what do I know?

Any chance they'll make a sex simulator with a simulated G-spot?
What is it exactly that the Swedish use these fighters for? Don't get me wrong... I think every country should be entitled to a proper defence force, but are these planes simply sitting on the ground, or are they getting some use? It's some pretty impressive technology the Sweeds have, so one would hope they're actually putting it to use. I'm just thinking that I can't recall hearing in recent memory of a Swedish border conflict, or a Swedish peace-keeping force. Is there anyone out there more familiar with Swedish military history that could enlighten us /.'ers?
I used to work for Wyle in San Antonio where they had a forerunner to the DFS called the ASDD (Advanced Spatial Disorientation Demonstrator). It was basically a cockpit the could rotate like a gryoscope and was mounted on a large, rotating motion base arm.

You can see the cockpit here:

Look behind the visible screens (which make up the simulated flight control tower). The fun part is inside the round cockpit behind the glass. That part spins around to produce up to about 3 G's. You can't see in this picture but the cockpit rotates around like a 30 foot circle once it gets going, plus it spins around it's own center.

Older technology, but still cool. In that lab we used to study how different kinds of motion would fool the inner ear. Such as, a pilot who is taking off and who looks over his shoulder at the ground will experience a balance illusion that will throw off his perception of "down". If he is not trained to compensate, and is distracted by other circumstances, this illusion can easy cause him to bank the plane into a crash.
