in offline long time i trying to write what found about il-2s, but, oh, this is so hard for one and ordinary guy like me, so, at this time, only about il-2 with 2 ns-37...
performance from compare 4.11 - weight 5732.96 kg (in tests, weight with full load, ie apparently 100 kg of bombs, around 6160 kg), 399 kph at sl (in first, apparently, tests speed around 387-391, but in game it's can be speed of late series) etc, just now personally i don't have full data... weapons - prototype had and was tested with 60 shells for each ns-37, and 200 kg of normal bomb load, serial planes had 50 shells for each ns-37 and 100 kg (normal) or 200 kg (overload) of bomb load, and - apparently - never not had any rockets, and although info about this different, personally i not saw any photos with rockets and think at this moment what planes really not had rockets... ie 2 cannons under wings + more weight = only bombs... so, apparently, loads for il-2 with ns-37 can look like 100 shells in total as default - personally my opinion, repeat, need and different ammobelts - 120 as prototype (for fun), plus something like 2xfab-50, 4xfab-50, 2xfab-100, some light bombs like ao-xx and ptabs=200 kg max... (maybe, DT can do for fun experimental il-2 with ns-45, as new load for il-2 with ns-37 or new plane, if i'm not mistaken, it's easy because plane just had new cannons (although, of course, in ideal need to do and all problems of ns-37/45)... and il-2 with ns-37 never not had wings with "стрелка" (or "крыло стрельчатой конструкции") - постановление ГКО № 4554сс, 13.11.1943, "Об установке на самолетах Ил-2, выпускаемых заводом № 30 НКАП, пушек Волкова-Ярцева калибра 23 мм вместо пушек ОКБ-16 калибра 37 мм" - ie in nov'43 resolution about production of il-2 with vya-23 instead ns-37 because cannon was not really effective by several technical and other reasons... another quote just about стрелка - "Как следует из документов, завод № 18 вышел на плановый уровень производства Ил-2 с металлическим крылом "со стрелкой" лишь к июню, а 1-й и 30-й заводы - к сентябрю 1944 г. Всего к концу года в ВВС поступило 7377 Ил-2 "крыло со стрелкой". При этом авиазаводы № 1 и № 30 выпускали самолеты и с металлическим, и с деревянным крылом. Все самолеты имели "стандартное" для 1944 г. наступательное вооружение: пушки ВЯ, пулеметы ШКАС, "эрэ-сы" и бомбы. Пушки НС-37 на них никогда не устанавливались." etc, although need more information, apparently, could be exeptions or something like this... well, and in very interesting "справочник по самолету ил-2, 1944", which recently was posted here, was confirmed information about 150 rounds for VUB-3 with UBT of il-2 two-seater (in game all il-2s have 200)... |

in addition to wish with il-2 with ns-45, if..., was tested plane with 100 shells in total...
i wanted to write about this later, in context of yak-7b with m-105pa, laggs'41 etc, but need too much time for all this things, so, i will start it now... well, here we have interesting project, with several documents about VVS which can be very useful and one of most interesting docs at this moment, i think, it's "альбом по дальности и продолжительности полета самолетов" (dated 1943, but, in fact, last plane was tested in end'45)... only some findings - page 11, yak-9 of 155 plant with 4 fuel tanks (673 ltr of fuel) and weight 3035 kg, was tested in july'42... looks like prototype of yak-9/yak-9d ie yak-7d... apparently, it's could be another confirmation of normal weight of yak-9d... page 12 - serial lagg-3 of 153 plant with sn 871 ie apparently 71 plane of 8 serie, 5 fuel tanks (452 ltr) and 3150 kg, was tested in august'42... apparently, it's one of last planes of 153 plant, similar with 7-xx series of 21 plant... and just quote about other lagg-3 of 153 - Quote:
page 22 - serial il-4... well, i'm know about bombers too little, but here in loads i see interesting things like 6 load - 1xfab-1000 + 2xfab-500 + 6xfab-100 = 2600 kg of bombs with limited fuel... Сита, это то о чем ты читал и хотел найти подтверждение? ![]() page 26 - serial il-2 with max. weight 6360 kg, was tested in feb'43... well, what very interesting here, it's 2 load - 6xfab-100 + 4 rs-82, and 3 load - 2xfab-250 + 4 rs-82... apparently, if it's really true, loads could be included in game... page 31 - serial la-5fn with sn 39210367, 3 fuel tanks (460 l) and 3300 kg, was tested in july'43 and what interesting here it's, apparently, confirmation of normal weight of la-5fn=3290-3300 kg in compare with 3320-3340 of some planes (ie, in this case, in game really NOT la-5fn type 41 or just 1944)... by the way, other confirmation of 3290-3300 kg (quote from "Отчет об испытаниях самолета "Лавочкин-5" с мотором М-71 N 39210204") - Quote:
Quote:
page 34 - just another lagg-3 of 31 plant, with sn 6672 (ie it's really famous 66 serie), with 3 fuel tanks (400 l) and 3023 kg, was tested in dec'43... page 36 - serial il-2 with ns-37 and max. weight 6150 kg, was tested in nov'43... i think, it's good confirmation of my last post (6160kg=100 kg of bombs and no any rockets)... page 38 - serial yak-9d with sn 0715306, 4 ft (645 l) and 3120 kg, was tested in feb'44... well, apparently it's one of first serial planes for tests, and it's why weight=3120... page 56 - serial il-10, was tested in may'45... i saw here debates about 2xfab-250 for this plane, well, 4 load - 2xfab-250 + 100 kg of other bombs... etc etc etc including many bombers, several lend-lease and captured planes... |

Regarding the weight, I agree, 3320-3340 kg is too much, but in my opinion, it should be between 3300-3320, like all examples in NII VVS tests. |

another interesting document - альбом "основные работы новосибирского филиала института летных исследований, выполненные в I полугодии 1942 года"...
page 2 - "improvement of flight data of yak-7" (1942)... in fact it's illustration, for example, of text from Stepanec or other documents which i reading, about aerodynamic changes'42 (shows etalon performance of yak-7(b) m-105pa, in compare with plane before changes, ie around 470 vs. 495 kph at sl) plus noted what gives forced m-105 with 1040 mm (plane showed 520 kph, although, pf in all sources have 1050, so, could be LITTLE more)... page 3 - "improvement of flight data of lagg-3" (1941)... well, looks like experimental lagg-3 with sn 31211062 and 490 kph at sl vs. lagg-3 with 3121715 and 457 from this table (later about this)... other works, mainly, for interest and have no practical meaning... |

last or one of last useful documents, "Сравнительная таблица летно-тактических данных серийных самолетов «Томагаук», МиГ-3, Як-1 и ЛаГГ-3.", with several performances of soviet-LL planes'41-42...
some notes - mig-3 looks like serial mig-3 am-35a with serial number 3943, slats and reduction 0,732, further original quote with more full performance (in other quotes about 3943 i saw 300 rounds for ubs) - Quote:
yak-1 it's serial yak-1 m-105p of 292 plant with sn 0511 - Quote:
lagg-3 it's, apparently, lagg-3 m-105p (pa?) with sn 3121715 (noted what "water cooler full closed") - Quote:
about p-40 i know not so much, be better if someone else compare this performance with full us/uk datas - moreover, in 4.12 new FMs for these early planes too, right? - but what i see - in 4.11 p-40c has 20.01 sec at 1000 m, in report 18, but speed more conservative... |

i think that now finally understood, how much speed lose la-7 with full open oil cooler and side doors (apparently, in all tests of all la-5/7/9/11 blinds after prop were open) - because found here, in table 7, serious error...
la-7 with full closed oil cooler=already 40 mm and full closed side doors=already 73 mm, it's correctly, how and all info about oil cooler, but in original documents just NO positions of doors, bad quality of scan (attached this page 15), only speeds - 488...487...480.5...4x7.5 (looks like 467.5) - ie apparently with full open side doors la-7 lose 20.5 kph and not how i'm assumed previously, 9 in total... in "techical description of la-7", page 154 - "Максимальному открытию створок соответствует их ход на 80 мм от крайнего закрытого положения. В крайнем закрытом положении створки не выступают за пределы обводов наружного капота. Для выхода воздуха и выхлопных газов боковая створка поставлена с некоторым повышением над задней боковой крышкой капота таким образом, что образуется постоянная щель." - ie 73 mm (it's constant crack and doors do not create resistance, attached photo) + doors can be opened on 80 mm=153, site gives max. 136 and min. 73, don't know why 136... on picture can also see, if i'm not mistaken, and new sides of hood for planes after start of production (quote from tests of 45210139) - "Самолет, предъявленный на испытания, отличался от самолета эталона 1944 года, проходившего государственные испытания в ГК НИИ, следующими изменениями, влияющими на аэродинамику: ...8. Укорочены боковины капота, прикрывающие крайние выхлопные патрубки." - look at 2 last exhaust pipes, top and bottom, and for comparision attached pic with la-5 etalon 1944 (but changes can be inside and this is only my theory)... in total, personally i think what 73mm as default it's almost similar with settings "по потоку" for old side doors, now for better cooling (with more easy managment of engine? looks like fw 190a) + because new doors and oil cooler really were much better than old, loss of speed was not so much (20.5+8.5=29 in compare with 45-50 for la-5fn)... confirmation about oil cooler from G. Serov - "Так было показано, что расположение маслорадиатора под фюзеляжем (за 5-м шпангоутом) в специально спрофилированном туннеле снижает его лобовое сопротивление в 2 раза и обеспечивает расход воздуха через радиатор на 25-30% больший, чем при серийном варианте." - resistance of oil cooler became lower in two times and through cooler passes more air on 25-30 percent... well, sorry for MY mistake... ![]() ...and that finally understood why in tables from Stepanets, and thus in many other sources, yak-9k and yak-9m have worst performance than early planes, well, just looks like that it's incredible mix of all planes and 518 kph at sl/6.5 min etc it's numbers from performance of yak-9t with 4 fuel tanks (not serial yak-9td or prototype of yak-9k) with around 32xx-3270 kg... for example, about prototype of yak-9k with 4 fuel tanks - "Из-за увеличения полетной массы максимальная скорость Як-9К по сравнению с Як-9Т уменьшилась у земли - на 2...15 км/ч и на высоте 5000м - на 40...27 км/ч; время набора высоты 5000 м увеличилось до 6,5 мин (на 1,0 мин);" - ie because extra weight, in compare with yak-9t this plane was slower on 2-15 kph at sl and had +1 min to time of climb to 5000 m... well, 533-15=518 and 5.5+1=6.5... but 533 (average speed of t/d in 43) - 15 kph it's strange, looks like that it's various quality, error, calculation etc... 533 - around 5-7 (more weight and another aerodynamics)=524-528 ie little less than average speed of yak-9d/t/7b in 43... about yak-9m PVO (in table with weight 3116 kg) - "Полетная масса Як-9М ПВО снизилась за счет уменьшения запаса горючего с 480 до 420 кг, масла с 45 до 30 кг, снятия брони - 16 кг и осуществления других более мелких мероприятий." - 3116 + 60 kg of fuel + 15 kg of oil + 16 kg of armor etc = at least 3207 kg of yak-9m as td version - 150 kg (in fact, 147.2) of difference between yak-9 with 2 fuel tanks and yak-9t = 3060 kg, almost normal weight of yak-9d/m with 4 fuel tanks... etc, with yaks-3 similar situation, 570 kph at sl of normal plane and 21 sec at 1000 of bad plane, although, it's not news... |

very good news for all adequate lovers of soviet planes, and especially for those who know language
![]() well, personally i long time not check this forum, although, meantime there recently were posted lot of FREE and very interesting soviet documents - many thanks to people who did this for us - including - 1 features of piloting of pe-2, 1943 (can be useful for tuning of FM)... 2 technical description of la-5, part 2, 1943 (looks like continuation of famous part 1, and i think, at this moment, that it's mainly for interest)... 3 armament of la-7, 1945 (looks like that i saw this before, if not mistaken, most interesting it's only confirmation about 390 shells in total, as official load, for la-7 with 3xb-20)... 4 technical description of lagg-3, part 2, 1941 (looks like just description, without most interesting parts about performance/weapon)... 5 technical description of boston III, A-20B and A-20G... and following documents can be interesting for many peoples because it's - 6 test of c-46a... 7 ground test of captured "Р-100" ie ki-46 with HA-112 (looks like that in something could be useful for japanese planes)... 8 test of me-109 g 2 № 14513... plus some information about u-2/po-2, tb-3/7, mig-1/3, ps-84/li-2, go-145a, r-5, ant-9, su-2, db-3f, SB, some tests of p-39q-10/hurricane IIc etc... |

Keep it coming 1984. All good stuff! So few are willing to try and document the details. I imagine at some point the Russian aircraft will be given a thorough look over... and this stuff helps.

yes, sometimes very, and let's hope that it's really yet not all...
Quote:
and even if in my last post not so much about performance/weapon/technical details, at least, has rare photos, drawings etc with very good quality... ![]() generally speaking, some documents which i found in last time can be researched for BOS, i thought about this before and if this - original photo from report, maybe, to some extent it's really true... and in any case, i think that 1CGS can help or, at least, hope no will be any bans for old "il-2" like with channel map etc, although personally i don't mind than focusing on other periods or even on other countrys (for example, early laggs'41 or several new models of i-16 etc or p-39/a-20/p-51 for many players)... by the way, at this moment, from free sources i collected many descriptions of defects, problems etc of soviet planes... of course, it's not only for soviet planes, and firstly need to think how it's can be realised - i just remembered these fuzes with defects in 4.10 or 11 as default ie without choice... maybe, not bad idea it's new option, something like "historical mode" with selected, neatly made several most common defects which can't be included in various performances of planes etc? although, here need lot of precious time, efforts and much more researches of really knowledgeable people, moreover, just different performances with 531 +12/-9 for yak-7b 1943, for example, can be enough... |
