Su flight model please

@OSD:
everything is much easier this is supposedly confidential methodological manual
miraculously snared much earlier than the flight manual for export version Su-27
it’s the same confidential methodicsLook at the weight and Cl max
All those information are FAR to much incomplete, not specific and not reliable.
Before even thinking of working seriously we need and not only 3 points
Gs vs Mach at various altitude
Or complete CL ( alpha,Mach)
Or turn rate (Mach, alt)CD (alpha,Mach)
Or PS curvesThrust (Mach,alt) curves
Possibly accel and decel curves
Everything with proper weight, atmosphere and drag index
Without all of this a FM would be as wrong as another

could you tell me what is the difference between chart a) and b) in you second picture ? would you thanslate the whole text ?
chart a) Its a table
text
Characteristics of stability and controllability of the aircraft without the suspension and with all types of missiles (A-A missiles) stored acceptable to angles of attack:
a) For airplanes with no suspensions or A-A missiles:M - Mach number
α доп - AOA limited be control system. The Su-27 has a system for limiting the angle of attack depending on the Mach number, AOA, G. the system can be switched off.
су доп. means CL - maximum value of CL realized when the angle of attack. The system of limitation is on.
For example at M=0.5 The system of limitation restricts access to the angle of attack of more than 24 degrees with AOA = 24 degrees maximum value of Cl = 1.85b) For airplanes with bombs up to 4000 kg or unguided rockets:
third attachment file 4.jpg
Cl chart
axis Y - Cl (balanced airplane, the results of flight tests )
axis X - AOA degrees
M - Mach number
Cl values for a range of M 0.3-0.8 marked to the left of the axis Y
Cl values for a range of M 1.2 marked to the right of the axis Y -
break, then write the answer in PM

@OSD:
OMG, facepalm.

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 aerodynamicsOSD I thank you for you informative and constructive comments.
I don’t remember you writing to me so I checked PM back to 25th Feb 12 & now understand a little better what you were saying.
As I don’t claim to be a aeronautical engineer I still endeavored to increaser my understanding of FM & encourage interestrest in Red side weapons & airframes
While I used your drag data as a references for my edits I apologizes for not using you lift figures, it was a long time ago, febuary.
In conclusian I started this as a personal learning interest as well as trying to keep a ballence in Red/Blue in our local engagements.
So if I can help you with the facepalm I would be more then happy.
Again thanks for all your help……Shad … no smiley
PS: I will change the credits & did you ever bother to fly the FM or are you just a forum person??

Talking about text books, any suggestion for an ‘easy’ primer on the subject ?

I have tried to use closer to “RL” drag/lift data as derived by other but it does not produce as “smooth” preformance as my previous.
It still needed to be modified around the edges, thats the only way I could get “supermaneuverability” to work.
PS Ill try to get some Fraps up soon. And its still awork in progress.
AFM is 70% done.

And for those who have pointed out that the MKK is not equipped with thrust vector.
Your stating the obvious, these things I know and have spent many hundreds of hours getting this far… The MKI does not exist in any current campaigns the MKK does so it is my current platform for testing in online MP campaign (RL), not only performance runs. My FM is generic SU-30/33 and can/will be tweakeded for 27/30MKK/MKI/MK/33/35 etc, it remains a proof of concept that “supermaneuverabilityty” is possiblele in the Falcon/BMS Sim.

??? That was already proved with the Harrier and Raptor in previous versions of Falcon……

Thanks Ram for your informative and usefully post.
Your attention to detail is just the key I needed to tweek those lift/drag relationships.
Im just a simple Electrical contractor with some engineering qualification trying to enjoy my remaining time.
So if your got something usefull or want to test fly it, that would be great.
Thanks ……Shad
PS: the point was can I get it to do what the real SU does or even close enough. And I have:munch:
-
Shadow, does the BMS database include the carrier based Su-30Sm fighters? If so, does your AFM change thier flight performance?
-

The only carrier based Sukhoi variant is Su-33 which is not Su-30 descendant. In /sim there are spearated dat files for each Sukhoi variants, only question that DB uses or not them.

Hi Chuckles, thanks for your interest. Its as Molni stated. This FM is in reality a SU with Thrust vector nozles. The SU-MKK was the convientent model to test/play with as it is in some of the established campaigns.
So if you install it save the original & go fly red. Its less of a wet paper bag now. Not as fast as a F-15e or Block 50/52 down low but better then it was. And carries a wide selection of A2A/A2G ordance.
Also this is only the OFM not a AFM. Also if it was submited for consideration as a “SU-30mkk” OFM its AOA abilities would be some what curtalied/reduced from the above file offered for preview.

LOL, your welcome, I’m just a simple Baker, HAHAHA
I have the FM, but I can’t check it out right now, it’s snowing and it’s cold as hell, gimme 3-4wks and I’ll be on it.

Hi Ram , Hot and muggy here, so take as falcon long as you need.
Cheers buddy

Some crude video footage
-
wow great …
Looks a bit slow more like a snail F-22 then a fast SU-30 but for sure it’s very impressive…
Also to add here: PLEASE 3d Magicians look at the miracle here and do a pit for this wonder…
Back to Subject… As VTOL is implemented couldn’t this be added to SU’s with thrust vectoring or I’m talking bullshit here?
-
I dont think VTOL and SU go together but its got grunt and plenty of lift for short takeoff.
EG the navel Su-33.
It comes into its own at altitude, low its a bit slow.

@Tom:
Great news! Hope my 3D model will help a bit….
