    I recently learned that F-15 has CLmax = 1.6 at 40 degrees AoA too ( very surprising TBH)

    If anyone who proficient in Russian can translate this ?

    Iam wondering what is the real Clmax of Su-27 , is it 1.85 or 1.6 ?

    earlier specification of Su-27SM.

    And that prove what ? where exactly it say Su-27SM has better range and combat radius than Su-35S ?

    still more than you

    And can you find anyone to vote for that statement ? Or better yes , can you find anyone that doesnot think you are a troll ?

    I’ve never said such thing and clearly stated that MiG-29K’s (9.41) empty weight according to P. Butowski is 12400 kg and for MiG-29M (9.41S) it’s 11600kg. While they share the same airframe, there are some differences which make the land based version lighter: lack of folding wing mechanism, arrestor hook, additional corrosion protection and some navigational systems necessary for carrier operations.

    My bad, when you said

    . The weight (again by P. Butowski) is 10900 kg empty for 9.12, 12400 kg for 9.41 and 11.600 kg for land based 9.41S

    I assumed that there are 2 distinct versions for Mig-35
    land based weight 11600 kg and sea based Mig-35 weight 12400 kg. If no landbased version was bought then that left us with sea version.

    Suddenly it’s 1,500? Where do you get that figure from?

    From lolek post at the start

    Of course they do

    Do we know what radar or IRST that Mig-35 version will use ?

    Can’t see how..

    I would guess it due to structure strength needed or stuff like that .

    What has this to do with the Su-35S? I am talking about Su-27S vs. Su-27SM.

    Since we are talking about the Mig-35 ( basically the latest version of Mig-29), i took su-35S as the latest version of su-27 too

    Well, it could be that there is no land version, at all and that the MiG-35 will be in fact MiG-29K sans folding wings and sans hook.

    So 1500 kg heavier than Mig-29 9.12 then

    There is an order from Egypt

    Do they have a fixed configuration yet?

    No.. not worth a mention, in fact

    But it does though, like a famous aerodynamic engineer once said “hole are heavy too”

    Yes.. It looks solid-mounted

    Fair enough

    F-35 requires a certain amount of fuel as heat dump, that can never be assumed,
    like a mig-21 model that had to keep some fuel for balance, -dead weight

    Unusable fuel is included in aircraft empty weight AFAIK.
    Anyways , i dont think F-35 is the only aircraft that need heat dump for avionics

    Participant

    i would have thought that the F-35 could?

    Actually you are correct.
    After recheck it. With 100% internal fuel, sea level :
    Su-27SK time in afterburner is 11.75 minutes
    F-35 time in afterburner is 12.9 minutes
    Su-35S time in afterburner is 14.4 minutes

    My calculation doesnot take into account fuel reserved so real time for all aircraft will be less

    It’s very specific to MIG35

    Sure because Mig-35 use Russian magic physics while others aircrafts have to obey normal physics

    Su-27SM is not Su-27S. Try to read with attention

    So what is combat radius of Su-27SM vs Su-35S then , troll ?

    I know what I know.

    Which is absolutely nothing

    From what I’ve found Zhuk-M weighs 220kg, while the old N019 weighted 385kg, so I guess the miniaturization may be enough to offset changes in the airframe

    N019 is an inverse cassegrain radar while Zhuk-M is a slotted array so i can see why slotted array is lighter. But I think it highly unlikely that a PESA or AESA would be lighter than a slotted array of similar diameter

    I’m afraid that 4500km is for Su-35S equipped with two 2000l drop tanks. Without it the most common values are around 3600km.

    Su-27 cant carry EFT ?.
    I have found that figures for Su-27 ferry range varied alot too TBH.

    BTW, if we use “same AB duration” for all jets, you will find F15 and F16 could outperform Mig29 and Su27 in almost every aspect. I will write a thread for that.

    I dont think anything can stay in the air longer than a Su-27 in afterburner apart from weird design like SR-71 or Mig-31)

    from engine upgrades MIG-29OVT will outperform MIG-29A in all flight regimes. and MIG-35 will outperform MIG-29OVT. there shouldn’t be any doubt about it

    Absolute moronic beyond words.
    Using your logic all aircraft will out perfrom their previous block on all flight regimes because they will always get a more powerful engine overtime

    nope. Su-27SM more radi

    Su-27S ferry range is 3700 km
    Su-35 ferry range is 4500 km

    the point of advance weopons is not export but squeeze money out of others. see Turkey business behavior after S400 in Syria. A country that can drill ground efficiently will have no problem with exports . I am sure once they see T-50 practically in Middleast there behavior will further change. the Syrian base is going to upgrade for 200 combat aircraft.

    but more important than exports is application of military power and the money flows to banks automatically. I put emphasis on word advance as you don’t have understanding of technology.

    But as MSphere says, the Irbis radar is a lot lighter vs older fire and control radars seen on Flankers

    Where do you get the information that Irbis-E is alot lighter than older generation of radar on flanker? I cant find their exact weight on manufacturer website but i find it highly unlikely

    Vs
    http://www.ausairpower.net/VVS/NIIP-Irbis-E-1.jpg

    PESA seem alot more bulky and more power will require more cooling too

    Chances are the OLS-35 is lighter vs OLS-27 etc.

    How heavy is OLS-27 ? i know OLS-35 is about 83 kg

    Actually, from my memory, the Su-27SM upgrade has resulted in decreased weight of the avionics

    I dont know specific about every single block but Su-35 empty weight is 18400 kg while Su-27 empty weight is 16380 kg , that is about 2000 kg different

    For the carrierborne version, yes

    The land borne version is 700 Kg heavier according to him, but iam not sure how many land version will be bought. Could be none

    The question is, however, what is the commonality of airframes of MiG-29K/KUB and MiG-35/35D

    Hard to speculate if there is no order yet.

    That’s really a marginal difference

    A different nontheless

    Yes, because the MiG-35 has got the carrierborne wing, only without wingfold, AFAIK..

    I recall that Mig-29 carrier version can fold its wing back , so Mig-35 lose that capabilities ??
