Yak-1b

[Friggitotti]

Hi all,

Is here anyone that Can tell me something on the yak-1b ? Like armament, Speed and specifications ?

I can't find nothing on this topic.

How long will be the discount period of the yak and the ju-52 ?

 

Thanks

[=CFC=Conky]

Hi,

 

If you look at the 1C store, you will see that the armament of the -1B will be 1X12.7mm & 1X20mm. Expect the new Yak to be a bit more nimble and faster than the current version.

 

Good hunting,

So there are not information about the modifications ?

[Trinkof]

Same as yak 1 I guess. Possibly a removed 12.7 , "light yak 1" experimentation (80-100 modified, served in combat).

[Finkeren]

We're getting a series 127, so I guess it'll have most of the improvements introduced through the first half of 1943.

 

Drfinitely more of a BoK plane than a BoS plane (though the very early -1b did see action at Stalingrad as a combat trial)

 

In terms of performance I don't think it'll be a radical departure from the Yak-1, though the difference will likely be greater from the -7b.

 

Its greatest assets likely will be the most obvious ones: 360 vision canopy and an UBS.

[ShamrockOneFive]

I love the Yak series so here's some information that I've been gathering.

 

The first one comes from Han and the developer updates:

 

Although from the famous Yak family of fighters, the Yak-1b (series 127) required almost a complete overhaul of the existing Yak-1 (series 69) 3D model. From the development point of view this is almost a completely new aircraft. There are several subtle differences that influence its physics model – a different propeller, automatic tail wheel lock similar to the MiG-3, simplified trimmers (just bendable fins instead of separate trimmer surfaces), improved seals for openings, additional engine exhaust covers, a different engine intake, and, of course, a lowered fuselage spine with a teardrop canopy. All of these changes led to better aerodynamics and performance than previous Yak models. The Yak-1b also had more armor in the front section of the fuselage and it had a different armament package. Armament consisted of a 20 mm ShVAK with 140 rounds and a 12.7mm UBS machinegun with 220 rounds. Designers also removed the underwing rocket rails.

 

 

Also there are some performance details that I've seen elsewhere such as this forum thread: http://www.warbirdsforum.com/topic/6068-yak-1-performance/

 

 

December 1942: 8th major operational version Yak-1B. 32nd Guards Fighter Air Regiment ( 32 GIAP ).

     *Turttle back was cut down and an all round view teardrop canopy was installed.

     *Armament: 1 x 20mm ShVAK + 1 x 12.7mm UBS.

     *Engine: Klimov M-105PF.

     *Combat Weight: 6,358 lbs.

     *Maximum Speed: 330 mph./S.L.,  368 mph./13,500 ft.

     *Climb: 3,650 fpm./S.L.,  16,400 ft./5.4 min.

     *Service Ceiling: 36,100 ft.

     *Range: 434 mls.

     *Turn Time: 19 seconds.

     *Wing Loading: 34.44+lbs./sq. ft.

     *Power Loading: 5.046 lbs./hp.

 

Throughout 1943 improvements were made to the Yak-1.

     *Aerodynamic improvements & weight reduction from 6,358 to 6,313 lbs.

     *Pressure bulkheads were installed to the fuselage.

     *A retractable tail wheel was installed.

     *Improved cowling & fillets were retrofitted.

     *Exhaust pipes were faired & arranged to provide some augmentation.

     *Air intake duct profiles were revised.

     *Finish of the skinning was improved.

 

There's some conflicting data out there as to some of the specifics but I think we can speak generally of the following things:

• Yak-1B Series 127 performance is all around improved from the Yak-1B Series 69
• Performance differences are incremental in nature so I doubt the Yak-1B will be significantly improved in any one way but improvements add up in a sum total
• Heavier armament and all around visibility will be among the largest changes that this aircraft will have

It's an excellent aircraft to have in the hangar for Stalingrad and Kuban battles but it must be though of as an evolutionary update on the Yak-1 design. It started operations in December 1942 at Stalingrad and was an essential fighter type through to the end of 1944. They were replaced by the Yak-3 as that aircraft arrived in significant numbers. The Yak-1B, although slightly lower performing than some Yak-9 models, was preferred for its handling by many Russian aces. It remained a popular type all the way through its service life and I'm guessing once it arrives we're going to see droves of it online... Not a bad thing either as there were 4,188 built. It will be solidly competitive with the Bf109F-4/G-2/F-4 at lower altitudes but will continue to suffer at higher ones.

 

I'm also going to be very interested in seeing what specific model the Yak-7B is added as. Although its clear that we have the one without the bubble canopy (essentially the last transition into the Yak-9) we may still be getting a fairly late model in the series. I'm going to make a solid guess that the Yak-7B will also have the VK105PF engine (in the Yak-1 Series 69 and 127) and it may also have a number of aerodynamic refinements that make it competitive in 1943. The Yak-7 was considered just as fast as contemporary Yak-1 models with excellent handling attributes but slightly reduced overall performance due to weight. The extra 12.7mm machine gun in the mix ups the firepower ante a fair bit. A small number even had a MPSh-37 cannon in the hub.

Thank you,

Last question, none knows when it Will be release ?

It'll come with the next update in December. Jason said "in time for Santa" (or maybe it was "Satan"?)

That is also on the pre-order page. Before the end of the year.

 

Likely with the next patch that we're speculating will contain the Yak-1B, Ju52, Bf109G-4 (BoK) and maybe even the DX11 renderer.

[LLv34_Flanker]

S!

 

 Yak-1b will be interesting. I liked it in original IL-2 as well. The visibility from cockpit was excellent. Still it was slower than Bf109G-2 and climbed worse. But overall a nice plane to fly.

[wtornado]

This gives you a good idea about the Yaks.

There is a little improvement at least.

If they go by the 1943 variant (which it should be), it's gonna be quite an Improvement.

 

531 km/h on the deck (which in this sim translates to some 560 km/h in winter conditions) ain't nothing to sneeze at, and over 1000m altitude gain in a climbing turn is pretty good.

[Max_Damage]

I flew a Lagg3 once. Got two pilot kill frags in one go. UBS is a good thing to have, it hits right through the plane and gets pilot and the engine. And then it will be the first plane with 360 visibility too. 

 

But then yak7b will have double UBS and at this point your weapons dont really get any better :D

The main problem with the Soviet armament, which is very good in general, is the very short total firing time, little over 10 sec for the Yak-1b, even shorter for the 7b I think. Both the UBS and the ShVAK fire so damn fast (to say nothing of the downright insane ShKAS) Your aim has to be right on to get more than 2 kills in one mission.

 

About the 360^o visibility: It'll likely be the best in the sim, but there will still be the headrest, and you need to look no further than the Fw 190 to see how obstructive that can be. There might be an armored glass headrest as a field mod, as was standard on the bubble-top Yaks in IL2 1946, but AFAIK wasn't very common before 1944.

According to the DEVUPDATE 123 the BOS Yak-1 does 516 on the deck. So the improvement will be nice but not world breaking. At higher altitude the difference will be a bit smaller 584 vs 592. The climbrate is more difficult to predict. If i can calculate an average time from the same page i would end up with 15,4 meters per second. The BOS Yak-1 has an average of 13,6. If you can take the average of the DEVUPDATE numbers.

Sounds about right. But considering that the BoS Yak-1 is already very nearly a match for the 109s below 3000m, the Germans are gonna need the 1.42 ATA on the G-4 to keep their edge.   

 

For me the striking number is the altitude gained in climbing turn (chandelle): It jumps from 650m for the 1942 M-105PF engined Yak-1 to a whooping 1150m for the 1943 "improved" Yak-1b. That's the same engine on an aircraft that weighs almost exactly the same. That's a huge difference.

I think the new Yak will surpass all the 109's on the deck, but not nearly on higher altitudes. And the climb-rate will still be considerable lower. But all in all, i think it will be a very nice addition.

Except for the climbing turn I mentioned above, I agree. However, if the Yak-1b actually nearly doubles the altitude gained in a chandelle (which I kinda doubt) then that'll make a huge difference.

650m? Nonono, that is lagg3 maybe. The in game yak1 ser 67 should be no less then 800 m. Bf109 is ~1100 m, yak3 and la7 are ~1250.

[Finkeren]

I looked through the chart and yeah, it does appear, that the number 650m is a carry-over from the very early Yak-1, which did have very disappointing climb performance. Comparing with the Yak-7b numbers it seems more likely, that the Yak-1 we have in BoS should do closer to 1000.

 

In that case it's incremental improvement again. But all these combined might well be enough to push the scales in favor of the Yak over the 109s (let's see how the G-4 performs) Still, improvement across the board with no real downsides other than firing time of the MGs. I'm looking forward to it.

[Brano]

Serial Yak-1b didn't have steel armored headrest. It would be kinda negation of implementing new type of canopy to increase rearward visibility. There was armored glass installed behind the head of pilot with 64mm thickness.It was standard factory issue,not a field mod.

Are you absolutely sure about that? (Well of course you are. You're Brano, I don't know anyone here who know the VVS planes half as well as you do)

 

It's kinda hard to see for certain in most contemporary photos, but in most cases where you can make it out, as well as in most Yak-1b/early Yak-9 reconstructions I've seen, there appear to be an armored headrest.

Come on,I'm no expert here :D

On first photo is maj. Yeremin famous first Yak-1b bought by kolchoznik Golovatyi. You can see transparent armored glass behind pilot.No steel armored headrest.

Second photo is in angle and rear glass looks a bit dark but you can still see the front windshield frame thru it.

Better to post some drawings.

This one is pilot seat with steel armored back (bronyespinka in russian) in shape that fully covers pilots body and head. Installed in Yak-1 with high gargot (as we have in game of series 69)

 

 

 

 

This one is from serial Yak-1b. You can clearly see,that back of the pilot seat is much shorter,covering pilot only to area around/slightly below shoulders.Head is protected by armored transparent glass.(in russian bronyesteklo).As you may noticed,it is glued of several parts.

Another questione is: what are the difference beetwen the yak-1 and the lagg-3 ?

[=WH=PangolinWranglin]

 

 

what are the difference beetwen the yak-1 and the lagg-3

To put it simply, Yak 1 (IMO) preforms better, while the LaGG has a harder hitting armament.

[Finkeren]

Like the difference between an axe and a spade. The axe is great for wrecking stuff and chop it to bits, while all the spade is really good for is making a big hole in the ground. 

 

 

(That's a bit unfair, I actually like the LaGG)

O - for optimism :D

 

bf109 has a better sustained turn time (worse radius though), better speed and quite better vertical. You can go vertical spiral and yak1 wont be able to follow pretty much.

 

maaybe it comes close but its not quite there yet :D

 

we ll see with yak1b. Historicall the first soviet fighter that beat german ones 1vf1 was La5fn.

Uhm, interesting info.

Question for you guys or maybe for Han. Do you think we get the bubble canopy as a mod in the Yak-7b?

Regards,

[216th_Lucas_From_Hell]

Very likely that not, Peterla. These were from different manufacturing series and had a couple other improvements (Brano knows best about this, but things like one less UBS), and were more Yak-9 than Yak-7. Mainly I'd guess that no because of the workload that goes into remaking half of the fuselage.

 

...I hope I'm wrong of course, it would be neat to have

[216th_Peterla]

Thanks my dear Lucas. I didn't think about the fuselage issue. Then I'm pretty sure that the mod will not happen.

Yes, the late models of Yak-7b with the bubble canopy were more Yak-9 than Yak-7, we don't plan to do it for BOK.
