DCS: AJS-37 Viggen Discussion

[BravoYankee4]

Another fun fact is that Viggen was the second aircraft in the world to have an onboard computer. The first was the Intruder...

 

Keep in mind that this is a plane that was initially projected during the 50's and the first prototype flew in the late 60's. Pretty amazing how much ahead of their time the engineers where with the design and how long the life time was.

Well me and my wife is looking forward to me start using that Automatik Fart Kontroll...

It was THE first using a onboard computer with integrated circuits. Not bad either. :music_whistling:

[MA_Goblin]

I've grown up with this bird flying around at my neighbourhood not far from F17 (wing 17). Later during my year as a navy engineer I had a lot of visits to colleagues at the workshops on the airbase :D

 

So looking forward to this machine.

Hmm so where do the Vigilante and TSR2 with their Verdan computers fit in :)

You're right. A few aircraft had computers onboard before the Viggen. I believe though that the Viggen computer, (the CK 37), was the first onboard computer using IC, integrated circuits.

 

IS this because Saab engineers were so ahead of the curve compared to the rest of the world as some in here seem to suggest? Of course no. At the time when the new central computer was being designed for the Viggen, early 60's, was the same time the first generation IC's, (American invention), became available. It's as simple as that I think.

Hm.... I assumed the author would have done a better research before putting that comment in a book. Perhaps the comment was about that the Viggen computer was doing more than the Verdan computer? I don't know.

 

A digital computer system designated the "Versatile Digital Analyzer (VERDAN)" -- which some prankster redefined as "Very Effective Replacement for a Dumb-Ass Navigator". It was one of the first solid-state computer systems ever fitted to an aircraft.

 

Anyway, with this knowledge I agree that "second" is probably not correct. One of the first is perhaps a more aqurate statement.

Well, the TSR-2 never became operational. Sadly... :-/

[Plagi_Arism]

Sorry guys but is there something official announcement about the Viggen?

Or is it only another wish or conjecture?

Well, the Viggen christmas tree formation was probably as close to a confirmation we can get from LNS :thumbup:

Thanks, now I see those Viggens. Those are a bit "foggy" (just like the Tomcat's silhouette) but Viggens.

Today when going home from Åre, Sweden(skiing holiday) I was keeping my eye open for road bases and its easy to recognize them.

 

This is the one I noticed today when going home:

A bit later we came across a Viggen standing in the open and decided to take a closer look to find another one. It was an old base(Optands flygfält) with a closed museum but it was free to take a closer look on the old base and the 37s.

 

Really incredible how easy it is to find stuff like this in Sweden :)

Cant wait for the Viggen and hopefylly some road-bases in the theatre

[Lucas_From_Hell]

Thanks for sharing T0x1s :)

 

Looking back I can now understand that a good lot of roads in north-east Västmanland I used to bike on that had odd-looking dead-end exits are actually emergency runways. What amazes me is how little room there is to maneuver, also how many trees there are and also how many of these runways are right by hills and such. Lots of skill to pull it off!

Are you sure all of those are road bases? To be honest only the last one looks wide enough for landing. :-)

[mattebubben]

Well the viggen is only 10m wingtip from wingtip.

 

So with a deadstick landing those roads should be quite possible.

 

But yes not all of those links where Road bases.

 

The first, Third and fifth links where most likley Road bases.

 

Most roadbases where 12-16m wide with the largest being 32m but there where also a large number of 8m roads to that could be used if the conditions where good.

 

Lenght and width depended on if the "roadbase" was intended to be used as an operational strip in a possible conflict or just as an emergency strip (in wich case it would be seldom used and at most one or 2 aircraft would use it)

 

12m was rated as minimum for a roadbase that where supposed to be used continuously with the 8m strips being alternatives (they where there incase they where ever needed)

 

Not every straight road in sweden with a road pocket was a Roadbase ^^ though many where, also kinda depends how close you are to an old airbase since most bases where "closeish" to a base.

 

The idea was it were too take no more then two hours to get personnel / equipment to any of the roadbases (2hours maximum from the closest airbase).

 

And as such most roadbases are no more then 100-150km from an old millitary airbase.

I love watching those Viggen road landings - they just get that front wheel down fast and throw in that reverse thrust and just seem to suddenly stop - it looks great.

 

I've always loved the Swedish aircraft - they look great, they are robust looking aircraft and being able to have them load on makeshift road airstrips is inspired - in the total war prospect of the Cold War, those fixed airbases would of been destroyed very quickly.

 

My only wish is that they do a Draken lol.

[T0x1s]

Sorry for not being clear about the links.

 

There were many hangars and parkings on roads close to real airfields where you could protect and hide planes easier. Most of the roadbases are connected or close to real military airfields so in case the airfield got destroyed you could hide the planes in hangars or parkways connected to roads that were connected to the airfields.

 

A good example is the 2nd google link. It shows a hangar connected to a road.

If you follow the road to the left you will find many parkways https://www.google.se/maps/@59.5955878,16.7393341,3a,75y,314.86h,84.29t/data=!3m6!1e1!3m4!1skOISzVaGWFRMae-VZDV-kA!2e0!7i13312!8i6656?hl=sv

 

If you follow the road to the west even more you will find Västerås(my home town) and the airfield. It was active a lot during the old days and it was operated by Tunnan and the Draken. Both of them are much smaller than Viggen and could easier be transported to the hangars and parkways as I linked. https://www.google.se/maps/@59.5876357,16.629257,3885m/data=!3m1!1e3?hl=sv

 

1 3 and 5 links are defiantly roadbases. The last being the biggest one. The other ones being reserve bases.

[El Hadji]

The road bases are easy to identify when you drive: First of all the roads are wider on those sections. There are also NO roadsigns and "viltspeglarna" (is there a English word for this?) are much shorter (only a few decimeters).

[BaconSarnie]

Google says viltspeglarna=wildlife mirrors

Cats eyes maybe?

The little reflectors the demarcate the centre of the carriageway.

If it is them then we call them cats eyes in the UK

[El Hadji]

"Viltpeglar" (wildlife mirrors) or "Viltreflektorer" (wildlife reflectors) are black and white plastic posts (that breaks easily if you hit it to prevent injuries) with cats eyes on them. These are placed along the road sides to scare moose and deer away when car lights hit them (you know we always drive with lights on i Sweden). They are also good for seeing the road edges in bad light conditions. On the left hand side there are two circular reflectors and on the right hand side a rectangular. The UK variant wouldn't work here because of the snow. Carriageways does not have these and they are only used on "A roads" as you call them on the island. :)

Thanks for the documents T0x1s.

Living in between F6 and F7 during the 80's gave me the opportunity to experince a lot of road base activities. A great time growing up :)

 

And please LNS, make the J-35 happen in DCS. If you ask me, you could cancel the F14 if needed :music_whistling:

[El Hadji]

Here is a good example of a road base belonging to F7 (home of the only airworthy AJ37) along Route 44 between Trollhättan and Lidköping. As you can see quite clearly, the road shoulders widens pretty much to provide some space. You can also notice roads very similar to taxiways in both ends (they are in fact taxiways...).
