Swedish AJ37 Viggen and upcoming J35J Draken simulators

[frazer]

Hi!

We are a group of simulation-geeks running a small private "flight simulation centre" in Stockholm, Sweden.

We are at the moment operating a AJ37 Viggen fighter simulator, previously used at F15 Söderhamn airforce base for pilot training. Since the 37 Viggen now is discontinued in the Swedish Airforce, we got to use this in a non-military organisation. The Viggen simulator also has a motion platform, not used by us at this moment though (due to lack of space and money). The visual system is a mirror-reflex (I'm not sure it's called that in english, just translated it directly from swedish "spegelreflex").

We also have a cut-off nose-part from a J35J Draken that we are preparing for full flight simulation.

We are as well working with a systems simulator for Boeing 737, including a visual system. This one is constructed from the bottom up, so it's a bit of a bigger project than the other two.

Here are some pictures of the simulators:

There is also a short and old movie featuring the Viggen simulator at YouTube: http://www.youtube.com/watch?v=4ZtV25nm9eA

A question for you FFS-guys: Can you think of any way for us to get 115V 400hz to the Draken Simulator for a reasonable price? All the equipment I've found on the internet costs way more than we can afford at the moment.

Hey Daniel,

Welcome to the wonderful world of simulation...

I did a little research and found this on Ebay...

It looks to be in good condition and honestly, you can't beat that price.

Good Luck.

Isn't Sweden 50 Hz?
The Georator 33 has been the standard low cost 400Hz source since the Wright Bros. They make different models for 50 and 60 Hz inputs though, so you would need to find a Euro spec'ed one.

Good point. I forgot the Euros were 50Hz.

Does it have to be absolutely 400 HZ?

400Hz is used for lighting mostly to cut noise interference in the cockpit.

Some of you more knowledgable folks can set me straight, however.

I know it powers instruments (ADI's and such), but I can't recall off hand if the frequency is critical. I thought it was used for excitation in instruments. The phase relationships should be the same, I think. So if you could get away with, maybe 333Hz, then running a 60Hz unit with 50Hz might be practical.

I haven't worked on 400Hz instrumentation much in a while.

Any thoughts?
