Su flight model please
-
If you guys have flown the Korea PvP I’m sure you’ll have noticed the leap in AI’s ability to dogfight in BVR and DF.
BVR is improved indeed… they just dunno what to do with themselves once inside 10nm

see next one

@OSD:
Keep stepping on a rake
FM Su-27 in the BMS is completely incorrect.No ! performance of stock Su-27 are public, and BMS FM of Su-27 are based on a reverse engineering of these performance data.
I do not know if you had only a look at Su-30, or also to other members of the Su-27 familiy, but in that case, you may have noticed that, in BMS, the Su-27 has a much more accurate FM than the Su-30. (and my opinion about the Su-27 FM is that it does not need to be changed).
If you want to improve the Su-30 FM, you should start from the Su-27 one (not from the F-15) -
Topolo,
Nice to see you are!!! Hope all is good.
Cheers,

If you are working on AFM I strongly suggest you PM me as you certainly need clarifications about many stuff in there
If there some documents about AFM info… please…

If you want to improve the Su-30 FM, you should start from the Su-27 one (not from the F-15)But the BMS Su-27 FM is aoa limited to 24. Su-30MKI/Su-35/37 has no aoa limitation……

This is the last iteration of my 30mkk SFM mod.
Started on a AFM for the Su-30/33/– Just before Christmas.
Topolo, any comments are welcome.
Out for maintance. (sorry it was a very old file with recent modify date ) Should have tested it again but still flying BFS.

Looks very cool.
Hows the animations ? Are they still default or have you been able to fix the main gear poping out of the wing root ?Thanks ……Shad
-
Great news man. Going well.
-
woah thrust vectoring is cool! does it actually increase roll rate… or it’s just for animation?

Whithout FM edit it just animation.

I am now and have PM you……
Some help will be appreciated, thanks if you can find some time.

No !
Yes
A simple example
The original model
AOA =24, M = 0.5, CL =1.2
Thrust (H = 0, M = 0.5) 28,250 pounds or 12,814 kgNow, the data from the flight manual Su-27 book 2
M < or = 0.5, AOA = 24, CL = 1.85This means that in the original FM at AOA = 24 degrees, Mach 0.5, H = 0, have insant G = ((0.7 * 1.2 * 62 * 10332 * 0.5 ^ 2) +2 * sin (24) * 12814) / 21400 = 6.77
Now correct data at AOA = 24 degrees, Mach 0.5, H = 0, insant G = ((0.71.8562 *10332 0.5^2) +2sin(24)*11747)/21400=10.13
performance of stock Su-27 are public, and BMS FM of Su-27 are based on a reverse engineering of these performance data
My dear friend
Please Provide the exact source of your public data, that you used for the calculation.If you want to improve the Su-30 FM, you should start from the Su-27 one (not from the F-15)
I long ago rebuild all flight model based not on reverse engineering Its build on practical aerodynamics for the specific aircraft.

This is the last iteration of my 30mkk SFM mod.
OMG, facepalm.
Shadow
I wrote to you, that you can not take the data separately. Separate Cl from CD and so on.
understand one simple thing that CL is inextricably linked to CD. Cd with Trust. but you choose your own way.
please take away of your FM mention about me, I do not want to have nothing in common with it
and buy a textbook on aerodynamics -

seems very unlikely …please provide manual SU27 book 2

There’s a few of us at 801st / UKF that enjoy flying red airframes against blue, but in BMS Red flight models are far inferiour to AF.
So is there any one that can help me copy say a F-15 FM in to a SU-30mmk airframe.
Or is there some one ( and I do relize the time/research involved) that can help do a semi decent FM for the SU-30mkk
Or a mod of the F18-c FM ??
……Shad
I do have manuals and performance papers of both. Contact me on TS …cant share in public.

could you tell me what is the difference between chart a) and b) in you second picture ? would you thanslate the whole text ?
have you the AOA vs MACH limiter curve ?
have you the CD (alpha , mach) as well ?
why many parameters seem hand written ?

While PM-ing you i just quick searched the net and stumbled over two pics
I know, nothing detailed, but i found it interesting to see them both in comparision like that.
