renhanxue Posted January 19, 2016 Posted January 19, 2016 (edited) I believe it is always deployed together with the landing gear, regardless if needed or not. Originally this was true but it was changed in the AJS mod (as well as on the JA 37, I believe) to deploy when the nose gear compresses at touch down. It's also deployed automatically in case of generator failure and can be deployed/stowed manually with a switch in the cockpit. It's also stowed automatically at gear up. (SFI AJS 37 tab 3 page 23; page 52 in the PDF.) I don't know what the purpose of deploying it automatically at touch down is, since it requires at least 300 km/h to deliver electrical current, but I've seen speculation that it might be because there's some service points behind the same hatch and since it's hydraulically actuated it can't be opened by the ground crew without hydraulic pressure in system 2, so it's always deployed on the ground. I can see the point of having it deployed at take off though, since it's nice to be able to instantly switch to reserve power in case of a generator failure at a critical phase of the flight. Inside the RAT hatch there's also a hand pump that can be used to build up some brake pressure, in order to be able to emergency brake the airplane while it is being towed on the ground.

RaXha Posted January 20, 2016 Posted January 20, 2016 DCS: AJS-37 Viggen Discussion I believe it is always deployed together with the landing gear, regardless if needed or not. I can confirm that it is! I asked one of the mechanics of this very aircraft this question a few years ago. :-)
RaXha Posted January 20, 2016 Posted January 20, 2016 Another fun fact! You can engage the reverser already on final, so it will automatically engage when you touch the ground! However, if you dont get your nosewheel on the ground within 2 seconds this procedure will automatically cancel and you will not have any thrust reverser. that is why they usually set it down hard and just push it into the ground to shorten the time it takes to stop and to make sure that reverser engage. Sounds like you would need a bit of practice doing this to avoid completely ruining the nose gear? :P
Goblin Posted January 20, 2016 Posted January 20, 2016 I can confirm that it is! I asked one of the mechanics of this very aircraft this question a few years ago. :-) As stated above, this was the case, but it was modified so the RAT (or "Millan" as it was called in swedish) extended with nosegear compression when landing. This modification was done to prevent fatigue cracks in the propellerblades.
ShadoWw Posted January 20, 2016 Posted January 20, 2016 Sounds like you would need a bit of practice doing this to avoid completely ruining the nose gear? :P What do you imply? This is there only as a safety pro cation so you cant use the trust reverser in the air, and when only having your main gear on the ground, it's only a safety feature and is there to save both the pilot and aircraft. if you mean the part when they slam it into the ground, the aircraft is made for it and in theory the landing gear should be able to handle carrier landings with ease.

mattebubben Posted January 20, 2016 Posted January 20, 2016 (edited) I can promise you we will get the Splinter camo. As that was the only type of Camo the AJS-37 used in service. The earlier AJ-37 used a Silver camo early on but for most of their service period the AJ/AJS-37s had that splinter camo. The Silver camo was used on the Viggens between 1970 (service entry) to late 1970s. The Splinter camo started appearing in the mid 70s (74-75) and by 1980 id say all AJ-37s had the splinter camo. the JA-37s had the Splinter scheme to start with but starting 1984 many received a Grey paint scheme (with a few different variations over the service time) So for most of the service period the JA-37s Units had a mix of aircraft in either the splinter or grey paint schemes. So The Splinter Paint scheme is a given (and most likley several differant ones from different units) The Silver Paint sheme is also very likely both for a early viggen scenario and since only flying AJS-37 has the silver paintscheme (it was reverted back to the Silver paintscheme it had when it was first deliverd as a AJ-37 and also to fit in with the other aircraft of the Swedish airforce historic flight group since all the other airplanes are also silver) And im also hoping for some of the cool paintschemes that emerged when the airplanes where leaving service. Many units painted one of their viggens in the unit color / logo for the last flights before they Retired the airplane type. And that gave birth to beauties like this. There was also an earlier variant from the same unit that was a bit more discrete There Are many more for the JA-37 that might be for the wrong variant but that are very cool non the less. (examples) This last one might be one of my favorite paintschemes =) It makes the Viggen very mean looking. Edited January 20, 2016 by mattebubben
renhanxue Posted January 20, 2016 Posted January 20, 2016 (edited) post your favorite viggen paintjobs David 12, painted to resemble the symbol for the order of the Viggen knights (member association for people who had flown the Viggen) Urban 48. "Akktu stakki" is Lule Sami for "lonely wolf" and is the name Urban Röd (1st sqn/21st air wing out of Luleå) chose for themselves. Should explain the wolf motif. Petter 11, commemorating the disbanding of the 16th air wing out of Uppsala. An aside about Swedish military aircraft callsigns during the later cold war: the wing number (painted on the plane beneath the cockpit) is translated to a letter (1 = A, 2 = B etc) in the Swedish phonetic alphabet, which is then combined with the aircraft's tail number to form a callsign. 21-48 above is thus Urban (for 21) 48. Squadrons are named in a similar fashion, but instead of the tail number you get a color: red for 1st, blue for 2nd and yellow for 3rd. The first squadron of the 4th air wing out of Östersund is thus David Röd (where Röd obviously means red, duh). Swedish squadron badges from the cold war are frequently hilarious, by the way. Forget skulls, pirate flags, grim reapers and all that American "badass" stuff, in Sweden they didn't take that stuff seriously at all and you get squadron badges like these: (the latin is a direct translation of the squadron's motto "Filip Blå kan ingen slå", or "nobody beats Foxtrot Blue") (source: http://www.uniformsdetaljer.com) Edited January 20, 2016 by renhanxue
RaXha Posted January 20, 2016 Posted January 20, 2016 One of my teachers (former JA-37 technician) told me that when they were doing a christmas card one year they painted one of their viggens in a batman scheme and the pilot wore a batman suit. Apparently this was not approved by the wings commanding officers, so there was a bit of a fuss. :P
BravoYankee4 Posted January 20, 2016 Posted January 20, 2016 post your favorite viggen paintjobs This one should have the John Player Special logo and it would look like Ronnie Peterson's car :)
CoBlue Posted January 20, 2016 Posted January 20, 2016 My favorite Camo. Seems very different from the "usual darker" Como, as it's more brighter. i7 8700k@4.7, 1080ti, DDR4 32GB, 2x SSD , HD 2TB, W10, ASUS 27", TrackIr5, TMWH, X-56, GProR.
RaXha Posted January 20, 2016 Posted January 20, 2016 (edited) My favorite Camo. Seems very different from the "usual darker" Como, as it's more brighter. Looks like it's parked in a museum of some kind and they probably had i resprayed. Looks like they mixed the colors a bit to saturated. Not many swedish forests have that palette of colors. ;-) Edited January 22, 2016 by RaXha
BravoYankee4 Posted January 20, 2016 Posted January 20, 2016 That looks more like some cheap vinyl. It's defenitely not the original paint.
Manuel_108 Posted January 21, 2016 Posted January 21, 2016 It really does look like it has been hitting the gym. If LN gets the engine sounds right then this will be my favourite module.
RaXha Posted January 21, 2016 Posted January 21, 2016 (edited) It really does look like it has been hitting the gym. If LN gets the engine sounds right then this will be my favourite module. Oh yes! Definitely! It probably wont be easy though, as i understand it getting realistic engine sounds in a sim is not easy, since it's kind of troublesome to record due to the very high volume, and also because the sound recordist can hardly join the pilot in the air since it's single seat only. :P I have faith though! The RM8A(and B) has a fantastic, loud, rumbling noise! :pilotfly: Edited January 21, 2016 by RaXha
Muppetlord Posted January 21, 2016 Posted January 21, 2016 I was at the Örebro airshow last year and there was a Viggen there. The sound was amazing. Reminded me a lot of the rumble you get from thunder. It was awesome. :)
Skjold Posted January 21, 2016 Posted January 21, 2016 Can confirm, grew up hearing Viggen afterburners high up in the sky. Awesome sound.
mattebubben Posted January 21, 2016 Posted January 21, 2016 (edited) The viggen is the only Swedish jet i have not yet seen on an airshow. only been close to one once but i was only 10 at the time where a viggen flew low over the water while we where out with our Sailing boat. The viggen (according to my dads recalling) passed about 300-400 meter away from our boat at very low altitude. I remember it but not all the details (my dad said he could see it was Splinter green painted) My dad though had plenty of viggen stories to tell as he did his millitary service as a "Flygbasjägare" (Translates into Airbase Ranger) During the Cold war these units had two duties the first was to set up defense around an airbase and in wartime to defend Air-assets / airfields from Hostile attack / Sabotage and as such he was often posted just at the end of the runways when viggens took off or landed. And the Second Duty was Recovery missions for missing pilots. (nowadays the duties aim more towards Search&rescue aswell as recce missions and to a lesser degree guarding airbases but the name remains) He did his service in the late80s/early90s on a Viggen only airfield in northen sweden. My love of airplanes and the viggen comes to a large degree from him and my guess is when i first show him the insides of a DCS Viggen il have to pry him away from my computer with a crowbar ^^. He tried to enlist into the airforce (together with his 2 best friends who both became viggen pilots) but was declined due to a slight Refractive error in one eye that closed that path for him so he instead aimed to become a ranger (jägare) and by happenstance he was selected to be a Flygbasjägare The Airbase Rangers where needed due to the way the Swedish airforce was planned to be dispersed in wartime (across multiple smaller bases / road bases across the nation) And as such They there more vulnerable to incursion by enemy troops wich necessitated dedicated elite units that could be deployed to guard aircraft stationed at smaller airfields / road bases. The Rangers where considerd an elite unit and where placed as the outer ring with "Close Protection Units" (similar to USAF Security Forces) guarding the inner ring (around the airfield). And if any Alarms where tripped or the Close protection found anything the Rangers would go to search the area (they also had dogs for that duty) and hunt down any hostiles (while the close protection unit held their place closer to the base) While the "Airbase Rangers" might not be directly tied to the Viggen they do link up with the Swedish airforce doctrine and the way the Viggen was Operated.

Goblin Posted January 21, 2016 Posted January 21, 2016 I did my military service at F15 in 92-93, so I'm almost as old as you dad then :) I served as a mechanic/crew chief. I remember questioning why on earth we mechs would have to carry weapons. We had to set them aside when working with the aircraft anyway. You never leave your gun, right? In the Swedish Airforce you do! ;) Besides, we had the Airbase Rangers. If the enemy got through them, and overran the flightline... Well, we would be toast anyway. I guess a conscript soldier can't understand every little detail of the military service..? :)

You excited to finally be the guy behind the stick instead of the guy doing all the actual work ^^
Goblin Posted January 21, 2016 Posted January 21, 2016 I also worked in the heavy maintenance workshop one summer, and did a school project about quality control in the Airforce. I really wanted to be an Airforce engineer. Flying was out of the question because of both hearing and eyesight. I ended up as a commercial pilot instead :) And yeah, I'm really excited about a DCS level 37!! I went back to F15 last summer and tried the simulator at the museum. It was really cool!
