i were seeking some information about Yak 9U, coz my squadii want to make skin for AH2.. and i found a lot of interesting informations...
like Yak could have 2 bombs, max speed were around 440 mph and so on
http://www.photovault.com/Link/Technology/Aviation_Stunt/AircraftType/YakovlevYak9.html
http://www.aviation.ru/Yak/
and this is only nice link, check out links on their Page
http://www.luftwaffe.cz/index.html
another link saying 9U were faster that 400 Mph
http://perso.wanadoo.fr/christophe.arribat/stofyak9.html
another link reporting ordinance on Yak 9U
http://www.flight-history.com/plane_stats/acModelView.php?makeId=186&makeName=Yakovlev&modelId=411
btw Yak 9U had no SHVaK but MP-20
may be same gun, like Lavockyn have ?
-
Perk the Yak
-
well if we compare those information with this, we will find, that HT`s Yak is somehow sloooooww :D

couldnt be bothered to read the links, but wasn't the Yak 3 with (vk-103 or something) engine the 440mph one?
-
Its a beutiful plane

Add 5 perks to everything made in '43, add 15 to everything made in '44 and add 25 to all 1945 planes (over what they cost now).

i say reverse it... early war planes cost perkies, late war earns them at a higher rate...
this will seperate the common dweebs from the dweebs who think early war planes somehow make for superior fights/pilots.
sort of like the winner of a bet pays.

Not speaking to the common thought you may be addressing but I do not believe that early planes do not require more skill or make for better fights. In fact an argument could be made to the contrary. What I'd like to see are more fair matchups. What makes for a bad fight is the lack of partiy between an early plane and a late one. 51D versus A6M2 or 202 versus La7 etc., those are boring and pointless matchups. You are a better stick than I am, but if my plane totally outclasses yours then (although I may not get an angle to kill you) I can guarantee you wont get me, so we'll play boom-dodge-zoom until someone runs out of gas. Not much fun for either pilot.

Perk anything that can carry more than 1k of ordinance.
-
The 434 mph top speed figure commonly attached to the Yak-9U comes from a performance test on the first prototype with the VK-107 engine. Tests on production aircraft resulted in a lower top speed than that of the prototype.
-
The Yak-9U is the fastest Yak variant of the war.
-
Its fast but not 434 mph fast.
About 415 mph max for production 9u, what's the AH 9u do? about 415?
So what is this thread about?

ahhh...I have been wondering about that.
thnx
Personally, (to address a different post) I like early war planes well enough in a somewhat equal matchup..but, the same goes for late war planes too.
and, kweassa, info I have (accuraccy is suspect) says Yak-3 is fastest. This is probably at low level though, but thats just a guess. Got any more info?
-
Yak-9U with a Klimov VK-107A:
*Conservative Figures
575km/h(357mph) @ sea level
672km/h(417mph) @ 5,000m
*Optimistic Figures
600km/h(372mph) @ sea level
700km/h(434mph) @ 5,000m
Yak-3 with a VK-105PF2:
567km/h(352mph) @ sea level
646km/h(401mph) @ 4,100m
The Yak-9U is faster than the Yak-3 both at lower alts and higher alts. It's effectively a lighter, a little bit more maneuverable, at a little lower altitudes version of the Yak-9U. The -9U comes from the "heavy Yak" lineage, and the -3 comes from the "light Yak" lineage.
The 'Yak-3 is the fastest' comments come from performance figures of test bed Yak-3s - about 50 aircraft produced, fitted with VK107A engines. These, never flew in actual combat in WW2.
-
ok, cool. wasn't there a yak-3 with a 107 engine?...My book says there was, but again, no certain date of delivery and no numbers in use. 447 mph for that one according to this book. I have certain reservations about most of the stats in it, but its all i have to go on at the moment.
over 400 for the 105 engined yak-3 is pretty impressive IMO
And, thank you sir.
-
lol...i missed the bottom of your post....my book says delivery of 107 engined yak-3's was no later than jan. 44. a wild guess maybe...or it just the beginning of tests. I misread a few things too. I does say that it never saw action in WW2, I just over looked it.

Whats your point about Yaks cannon,Bombs ?

what about... zillion other sources say, that 16000 Yaks were build before War ended.
read links i posted

But not the Yak-3 mounted with VK-107A engines.
Read what I wrote down.

late war planes probly take a lot less skill to survive in than early war planes in an arena that mixes late and early war. But the real problem is that the more late war planes you see the less good fights you see. The yak is and La7/5 are about the best combo of turn and speed so they are the least boring to fly/fight
"Soviet Combat Aircratft of WWII" has lots of very fast and fast climbing soviet aircraft in it but... allmost every one of em is the prototype and most say something like "but the plane was much slower when delivered..." or "finished versions were a disapointment.." or... "overheating caused the production version to use the #### engine and performance was down by##"
they were light aircraft and the armement and armor were a huge percentage of the total weight.. the prototypes were stripped with engines that were leaned out and overdriven..

not Yak-3 but Yak-9U with VK-107A
fom the page i posted
"Contrary to the Yak-3 which would appear one year later as a pure dogfighter, the Yak-9 was designed as a multi-role fighter."
My question is pointed on Ordinance and Cannon, not on speed now.
lol from russian site :D
Yak-7R - Jet version project. one liquid fuel jet and two ramjets. 1942.
-
What I'd like to see are more fair matchups.
Come fly the CT.
-
Big Yak fan here.
With that said, compared to the things which have been dug up in various "battle of the sources" threads in the AC and Vehicle forum, these websites don't have a lot to offer.
Anyone have any info on the "MP-20"?

Then obviously it was incredibly dense of you when you responded to BlkKnit's;
It does say that it never saw action in WW2, I just over looked it.
..comment, as clearly we were speaking of the particular type of Yak-3.
