Su flight model please
-
Can I get it for testing? (Just for fun)
-
I can but it would be an older version, as the more I learn the greater the revision needed.
This week Ill post some thing……Shad
PS: The SFM is leading me into the AFM…it might be beyond me but the SFM is (in my view) a reasonable replacement for now.

fulcrum next?
Interesting - I’ve just created new a thread concerning precisely the AI pilot’s lack of ability to dogfight at correct airspeeds (and aceptable turn rates), because dogfighting against the Fulcrum seemed to easy.

If you like the MiG-29, you’ll love the MiG-35.

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…

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.

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
