DCS: AJS-37 Viggen Discussion

[microvax]

What options are there for targeting the glide bombs?

 

In other words, do we have to type coordinates into the INS or are there alternate methods? (i.e. using the HUD to designate a target like in the A-10/Mirage)

 

Someone said it has a target of oppotunity mode more like a traditional bomb, so possible.

 

But main mode of release is just by coordinates afaik.

Sort of related: Anyone know how the radar is integrated with the weapons in general? Let's say you find a cluster of parked tanks on the scope. Is that information sent to any of the weapons systems or does it simply act as a map?

The radar can't find ground targets. It's used for navigation and finding naval targets mainly.

that is the a2g radar you are getting.

 

You can spot things the size of a antenna mast, you can spot big terrain features and a well experienced operator may spot an aircraft afaik, but the max range resolution you can put it on is 15km, so imagine the part of 15km a tank is on that screen.

 

So yeah, it acts as a map afaik for most of the time. But for RBS15 programming you actually have a cursor on the radar image so dunno. We will see.

 

But for sure it will be stil up to you to manually interpret the image you are getting. Since Leatherneck has implemented raycasting and implemented different reflective characteristics for different objects, well possible that a experienced observer can kinda make things out, but there is nothing like target recognition by the radar or anything in that regard.

Well Leatherneck devs said you may spot aircrafts if you are a experienced operator iirc. So maybee you can spot a helicopter since its reflecting more then the average soil, but for a tank

I do not have my hopes high. I guess its possible to make out target groupings since the reflection from that area should be stronger but no hopes for indifvidual targets tbh.

Not to bash your performance or anything but a lot of the simulators in museums etc use an extremly simple flight model that wouldn't represent the difficulty of landing it properly.

LOL the simulator was not something in a museum. It was THE simulator the pilots used. Back then (early 90's) I don't think museums even had simulators. I did get guidance from an instructor over intercom but the cockpit was the JA37 cockpit which had its own hydraulics system. The computers were housed in a separate room.

 

Again not trying to show off, rather the opposite. My recollection of the 5-6 flights I did was that it was surprisingly easy to fly. All of us that was part of the Air Force Youth got to fly the simulator. I got lucky and got to fly it several times. The attached picture is of me from those days, I thought I was really cool (back then) posing next to a JA37 in my Ray-Bans. :)

I can't remember reading that low-alpha landings was a design criterion for Viggen? I might misremember or missed it but all I can remember reading is the short-field requirements (<500m), and that the design should be mechanically simple (ruling out variable wings), "good maneuverability" and then nothing else. Don't know what is considered low alpha while landing and if 12 or 15,5 degrees qualify as low or high but a short Google-search for comparison gives the F-4 at about 10 degrees and the F-18 at 8 degrees when landing at a carrier.

 

Since this has come up before I think it's important to get the right expectation of how the Viggen flies and understand the trade-off of the severe induced drag that is inherent in its design. I suggest reading more on Wikipedia on the topics of induced drag or aspect ratio or searching for "Aerodynamics of the Viggen 37 aircraft". If nothing else you might want to read this interview with a Viggen pilot: http://www.warbirdsnews.com/warbird-articles/swedish-air-force-historic-flight-cockpit.html

It was from a documentary and wiki but low AOA is probably only if you compare to delta wings without canard configuration.

Fair enough, you didnt specificy in your OP what simulator or what decade this was in, nor where it was etc. :thumbup:

[renhanxue]

Today I (and probably many other regular posters in this thread) went to the Swedish Air Force 90th anniversary air show. Today was a good day.

 

 

 

(I don't have a telephoto lens so go elsewhere for your hot Viggen closeup pics)

It sure was a great show!

[Marsvinet]

Got lots of great pictures of the viggens, makes me excited for the digital rendition of it. (And I spent much time close to the Blackhawks... hehe)

[reilar]

It sure was a fine day.

Really great day :D

[Skjold]

Was indeed a great show, sadly have a shitty camera so just photos of static displays really :) Nice to see a Viggen flying again, last time was sometime in the early 2000s.

[foxmaner]

beautiful show. And cool to see the viggen irl for the first time. Think it was by far the loudest plane on the show :D

The SAAB 35 Draken usualy gives it a good run for it's money when it comes to being loud, but it's probably a close call. :P

[mattebubben]

Yea a great show.

 

And great weather =).

(some wind but otherwise amazing)

Was lucky enough to stand in the right location for the landings so caught the entire 5 group as they landed (Gripen,Viggen,Draken,Tunnan,Sk60 etc)

 

so was able to get some cool pictures as they landed as they flew over me at very low altitude when they were on short final.

(flew over the walkpath just a few sec before touchdown).

 

Dont have a great camera but at that short range even my camera could catch them xD.

 

But yea just got home after a long Train ride back north.

 

And the weather for those that went today was not as nice ^^.

Gonna see her on friday! :)

There was a joke in Finnish Air Force that described Draken as "the best known way to convert jet fuel into noise" :D

Haha! My old aircraft maintenance teacher (a former Draken mechanic) used to call it a "fantastic fuel to noise converter"! :pilotfly:

[MikeMikeJuliet]

It is interesting to note how big Viggen is... I mean its not the largest of aircraft, but compare it to Draken and Gripen... massive... The extra wheels on the main gear may help bring a bit more "umpf" to the appearance... what's the MTOW on Viggen?

[Cobra847]

Gonna see her on friday! :)

 

Me too! Exciting. The Airpower programme looks excellent :)

[JaNk0]

Where is the airshow?

[mattebubben]

im guessing they are talking about the AirPower 16 Airshow in Zeltweg Airbase Austria.
