    This is the horizontal acceleration-time graph for the MiG-23ML with its engine at full afterburner, with a fuel remnant of 2000 liters and carring two R-23 missiles.
    We can see that the MiG-23ML will accelerate from 600km/h to 1100km/h in just 22 secs with its wings set at 45 degrees and at 1 km of altitude

    This graph shows values for the different sweep wing angles of 16, 45 and 72 degrees and at different heights of 1km, 5km and 10km

    Thank you!
    I just found these documents when searching through airwar.ru
    I am really delighted about the quality of the graphs and actually was able to identify most of the graphs. I gave some to russian-speaking fellows and hopefully will have a useful performance model of the MiG-23, MiG-25 and MiG-29 soon.

    I think the document will help you a lot because it also includes some math, not as simple some times but definitively not difficult for engineers.

    You also can compare some data and gave a more realistic idea of the MiG-23 performance.

    I found for example that the MiG-23ML will accelerate at 1000 meters of altitude from 600 km/h to 900km/h in just 12 seconds, The F-18 for exmaple will take 18 secs from 600 km/h to 1000km/h at 1000 meters of altitude

    Here is another page

    Here we can see another view of a MiG-23 executing a loop, however in this the altitude changes very little little nonetheless the diving angle in the second part of the loop changes, we can see that in one the angle is 27 degrees and the other two are 24 degrees and 20 degrees respectively.

    We can see that the tighter angle of 27 degrees bleeds more energy and speed than that of 20 degrees, however it is executed in less time (only 33 seconds)

    Hallo MiG-23MLD,

    thanks for sharing these valuable documents and offering your help in translating it. I am especially interested in performance evaluation and in using the provided data to model basic characteristics. I need to take a deeper look at the material and will then come back to you.
    Do you have drag coefficient (that must be something like cx in Russian coordinate system) over Mach number? I saw that in another Russian document. It is very helpful, especially if it comes with curves for different external stores.

    Thanks so far.

    P.S.: Damned, has been a considerable time since I posted something. :p

    I will try Schorsch as soon as i find the page if it is there i will translate it gladly for you

    Here is another page of the MiG-23ML manual, in this one you have the time it takes for a MiG-23 at different sweep wing angles to execute a horizontal turn and the respective disacceleration it produces.

    Starting from a speed of 900km/h at 5000 meters of altitude, it will take 23 seconds to do a 360 degrees turn at the wing sweep angle of 45 degrees, this will disaccelerate the MiG-23ML to the speed of 490km/h.
    It will take 37 seconds at the sweep angle of 72 degrees
    Also you have the same information for different altitudes in specific 10km and 5km

    Thanks Pesho

    here is another interesting MiG-23ML manual graph, despite it is commonly overlook vertical turning or looping, it`s a very important parameter to see how good an aircraft accelerates at turns.

    In the following graph we can see that if the MiG-23ML starts a climb and executes a loop depending on the G forces the MiG-23 is exposed the MiG-23ML will gain altitue.

    We can see that the MiG-23 starts this loops at the altitude of 1000 meters flying at a speed of 950km/h, the MiG-23LM sweep wing angle is 45 degrees and its weight 13000 kg, let`s notice the MiG-23 starts the loop at an slope angle of 20 degrees

    This chart basicly is to show the relation between speed, max overload measured in in Gs and altitude

    we can see that higher the G load the MiG-23 sustains in the loop, lower will be the final speed at the end of the loop and altitude it reached

    This is a very important parameter because shows how easy the fighter can out accelerate and out turn an opponent in the vertical plane

    The chart says that for each decrease of 0.5Gs the MiG-23ML will gain around 300-500 meters of altitude

    Also:
    Time for acceleration:
    from 600 to 1300 km/h in 1km heigh-30s/48,5s(UB)
    from M=1 to M=2 in 10-12km heigh-160s/210s(UB)
    Max range
    Wing at 16 degrees,M=0,74-0,77,heigh 10-12 km:
    without external tanks-1450/1210(UB)
    with 3 external tanks-2360/1550(1 tank)
    Range with 3 external tanks,2 R-23 missiles on 200m heigh-900km

    MiG-23MLD i see that you ofter copy info from airwar.ru and there is several manuals in the book section.Here is some of them:
    http://airwar.ru/other/bibl/mig21pf.zip -MiG-21PF
    http://airwar.ru/other/bibl/mig29um.zip -MiG-29 manual for battle exploitation

    …..i see that you edited your post before i post mine

    Pesho what is the main page of http://www.airwar.ru for the manuals can you give me the link please thanks in advance

    Today i found the MiG-23ML max turn rate of 16.7 deg/sec and its max sustained turn rate of 14.1 in the MiG-23 manual i am so glad 😀 but i wonder why Yefim Gordon did not mention it?

    …thanks for the correction

    No F-4E-MiG-23ML but at least SU-15 MiG-23

    Yes MiG-23MLD,what about this top view of Su-34 and -24 made by A13x

    I think those aircraft are not at the same scale, the Su-24 is a bigger aircraft than it usually looks, bigger than even the F-111 and Su-32/Su-34

    One of the greatest fighters ever flies again.

    Here are some pictures showing the big difference between the MiG-29 and the Su-27 in size

    please try your very best to restrict to ONE PICTURE… NOT ur entire ALBUM

    Thanks! :diablo:

    I will but there are so many pictures that are so loveable, of so many aircraft, it is hard even to just post two, but i guess personally the aircraft that always looks from a front view is the Rafale and up to this moment i guess that Rafale picture leaves the rest behind

    some of my work

    Ha27 i guess the Su-24 and Su-32 are not at the same scale, up to what i know the Su-24 is a big animal almost 24.53 mtrs while the Su-32 is a little bit smaller just 23.34 mtrs

    here is the data from the Sukhoi web page for the SU-24

    Размеры самолета: самолета:
    – длина, м 24.532
    – размах, м 17,638 (10,366)
    – высота, м 6,193

    data for the Su-34 measures:Размеры самолета:

    Yeah, looks like I may have added it incorrectly, will fix for next revision.
    Any other addition requests?

    It is superb but i guess you need the Tu-160 Blackjack in that chart

    Here is to see the size of the Su-27 with respects the Mirage F1
