DCS: AJS-37 Viggen Discussion

[CoBlue]

Just like with the F-22, The Air Force admits they don't show all of it's capabilities for airshow demonstrations (of course some of these aren't possible to view from the ground). Why show all the tricks up your sleeve?

Viggen hasn't been in active duty for 20 years or so, thus there's no "secrecy" involved in it's capability's.

How can you compere Viggen that is no longer in active duty, but still doing airshows, to an F-22 ? :doh:

Cuz reasons lol :P

 

In the video above of the slow pass, he is not even pushing it! Look up some older videos of an AJS or JA37 doing this slow pass! they fly much slower and goes past the 90 degree mark! he was most likely doing about 250 km/h not banking much more than 70 degrees, the used to fly about 220 when doing this maneuver.

It is ofc understandable why they don't push this aircraft close to it's limit, No full reversing, not a whole lot of 6g maneuvers. All to preserve it as long as they can.

[ShadoWw]

We do, but it's not very necessary. The aircraft is incredibly well documented.

 

Since the aircraft has not been in service for a long time; you run into a lot of "forgetful pilot syndrome"-- where recollections do not match documentation.

 

Yo Cobra! got a question for you! Will you add the later program they put into the AJS37's which allowed them to do toss bombing? using the CK? You guys should look it up, dont know how much info there is on it, but i know a few former pilots which did use it a bit and it was a pretty effective way of dropping all your 16 bombs without even having to expose yourself. :pilotfly:

Already a feature :)

Great! I'm gonna go out in a limb and guess that the AJS we are getting has all of the upgrades made? (I have no idea what those where or how many of them there were :P)

[ShadoWw]

Already a feature :)

 

Wonderful :D

 

is the very poor performance of the way the aircraft updates your location featured? A pilot told me just today, you have to do "fixes" fix your location quite often, for example tell your radar that this is that, so it from there knows wheere you are, example a certain beach on a lake, you tell the radar "hey there's that beach" and then it'll be accurate again, but left without updates after an hour of flying, it might be showing you up to 20km wrong

The drifting of the Nav system has been confirmed to be modeled :-)

Love to see LN break the silence and give us some info. Thanks <3

It's great! :D can't wait for the release! :D

Beautiful! :D This keeps getting better and better xD

Hopefully that means we might be getting close.

Atleast close to some official news.

My guess is we have about two weeks left.

Two Weeks™ :lol:

Viggen had the ability to turn very sharp, but it was always followed with rapid loss of speed, in a split Sagainst surface sped wasnt that much of a problem, and one thing that makes many AC need lots of height in that manouver is rapid gain of sped. So i dont really doubt that altitude from what i have seen the viggen i slow speed register, it is always a part of the flight demonstrations, slow speeed pass with high alfa...

 

Not sure what u are debating here, safe manouvers versus manouvers that happens in combat isnt the same, and the fact that the Soviet pilot followed in a Flagon, is almost more incredible, that must have been a given outcome for most Soviet AC's, but the Flagon more them the all of them.

 

all shows include a slow pass, uniqe properties in that region

 

I don't think you understand, it's not about going slow, it's about keeping within the right speed envelope throughout the maneuver. Too slow and you won't achieve Rmin, too fast and you wont achieve it either.

 

As for slow passes the above is not that special, check out this F-16 for comparison:

I think the point of that slow pass the viggen does is to display it's maneuverability at such slow speeds.

Next to last research trip was conducted today, with the great JA-37Di at Graz-Thalerhof.

 

Unfortunately a bit different than our AJS-37; but still a great tool (amongst others) to ensure maximum graphical accuracy.

We were finally able to solve some cockpit accuracy issues due to lack of reference (on major cockpit parts, nonetheless!). Canopy elements can be a real PITA to get good reference for.

 

Progress is very strong, looking forward to being finally done!

 

Good to hear progress i strong. Hopefully the last research trip isn't too far in the future.

 

Really looking forward to flying the Viggen soon™. :)

Rocking the wings doesn't really showcase that ;) Also it was going appreciably faster than the F-16.

 

Either way it doesn't change the fact that there's no way the Viggen would be capable of completing a split S within 400 m or even 500 m in height.

There is a Viggen in this picture.

There's also a reason why I think Scandinavians and their descendants in the US are insane.

ouuuh nice picture !

[foxmaner]

Any reasons why viggen fly with gear down at airshows? Seen many videos in the thread when it does that.

I guess according to the info/speculation form this thread, the canard flaps only delpoy with gear out. So yeah, thats probably the reason.

This is correct. They deploy the gear when doing the slow pass since it needs the canard flaps to be extended at those speeds. :-)

I have seen NF-5 and F-16C perform in airshows and they too deploy landing gear for low speed passes often. In F-16's case I think it is because FLCS acts different with LG down and allows much greater AoA than normal. Not sure what the reason would bevin NF-5's case.
