Su flight model please
-
Yep have been compairing su27, 33,35,37, F14,F15 ect as a basic study. AFM is not in my ballpark.
Doing some basic edits for educational purpose. ect
-
Good to see m8, You saw what I was trying to tell you all is possible with the right information hey… keep in contact m8
-
A interesting dialog on the SU-30mki by Colonel Terrence Fornof. He gives a lecture on Red Flag 08

@ Shad… I totally agree with having an AFM for the red side. The SU30 would be a perfect canditate and I’m sure there are many who would enjoy flying for the North. What is needed to get started?
-
Just a note. Performance curves of '21 and '23s mostly unclassified any they are the most common OPFOR jets, especially for Korean theater.
-
Dont want to fly 21 or 23s,
Did fly a 23 , killed two F-5s a F-4 & then ran home, it was fun but it woujd be cool to have a general purpose Mig/SU to mix it up.
Cheers–Shad

Does any one nave a comment on getting ECM programs to work in standard flight model airframes ???
Thanks ……Shad
-
add:
hasEWS 1
to additional data
cheers
-
Ha max that was the first thing I tried.
Just checked my spelling/format,Im such a dumb ase, I edited the Su-30mkk-copy.dat :oops:
Thanks……Shad
-
If any on is interested in trying a modded Su-30mkk/mki flight model please post.
Found a few inconsistences in thrust tables ect as well as bringing it up to published specs.
Still doing study on drag tables ectEWS programs functional, F-16 pit so its flyable for the average joe.
A good multirole for “REDonBLUE” campaigns.
Let me know ……Shad

In first step better HP and rack config is required to at least got a better drag by weapons.
Do you have any thrust char data about AL-31 engine…?
-
u mean this:?

I will try to find who is able to translate this.

Hi gents, are you guys thinking of adding a SU-37 or SU-33 FM at some point I like this discussion Sukhoi SU series nice A/C’s!
Cheers,
:drink:
-
Top of left graph look like full mil thrust curves I plotted from existing FM, & so will be helpfull….Thanks
Top of right graph resemble AB thrust curves etc etc etc.Bottom of both may be Drag/Thrust ratios.
Yep some translation would be cool.
Im still searching for reliable data.
Thanks…Shad
PS; Those charts will be of great help, again thanks. As performance curves are really all I need for the thrust tables.
Absolute values can be easly adjusted as long as I keep the relationships. -

Weapon drag will be a fair peice of work. Looking at clean skin for now.
Do you have any thrust char data about AL-31 engine…?
Still havent found any well documented &/or comparitive tables.
Cheers……Shad
Edit, the more I study Artys link/chart the more confident I am as to the changes I have allready tested.

The left side shows the max. mil thrust depending on Mach number and altitude. (upped part) Thrust is in kN. Bottom part shows the specific fuel consumtion, but I cannot recognize the unit. I had a contact but it taks a time to get a reply. Right side is the same, but it shows the max. AB thrust.
One aspect. You can use the same scaling factor for RPM-thrust char. that you can see for F-15 or F-16. If you do not have data you have to use something similar…
The problem for modeling the effect of RPM on specific fuel consumption. In dat files you can see some data.
_nEngines 2
typeAC 3
typeEngine 2fuelGaugeMultiplier 10
fuelFlowFactorNormal 0.69
fuelFlowFactorAb 2.17
minFuelFlow 860_I do not know how is defined the RPM - consumption char. (linear by which factor…?)
I do not now how calculated the effect of altitude on fuel flow.Does type of engine have effect on characteristics…? Does Falcon use inbuilt, pre defined spec. consumption curves which can be weighted with factors?
I do not know what defines the flow factor. In DB you can find also a fuel flow modifier value. Which one is used?
Quite a dark area for me the whole fuel flow-thurst-RPM-speed area. As I can judge most of AC fuel flow is far from RL values. Most of AC can fly very far at very high altitude comparing with RL ferry or combat range.
It seems to me harder to set a correct fuel flow than thrust curves. It is not easy to transform curves…
-
Yes Thrust values are easy to work with, but have not yet been able to find fule flow characteristics.
In flight testing against F-16, F15 & EF2000.
Cheers…away for a week…Shad

Don’t want to digress too much from the technical data side of this thread…
Raphael, Coco and Shad took up the Typhoon, F15 and Su-30Mkk respectively. We did some very basic testing at different altitudes… angels 10,20 and 30.
Now keep in mind this is with Shad’s latest tweek of thrust to weight ratio for the Su-30Mkk and the FM for the F15 may not be as accurate as in RL. ( very rough testing )
Takeoff at full burn was fairly equal between the three jets. At 10,000ft the F15 had better acceleration than the Su-30Mkk from mach .99 to 1.38 and continuing to aprox. 1.5 mach.
At 20,000ft the F15 out performed the Su30 but not as radically as at 10,000ft. At 30,000 and higher, the Su30 came into it’s own and was out accelerating and out climbing the F15.Shad’s current .dat tweek has the Su30 out performed at lower levels but above angels 30 the Su30 starts to show its true potential.
We look forward to an accurate and “fair” FM for the Su30Mkk and I’m sure it will prove a worthy adversary to the NATO forces in BMS.As for Raphael and the Typhoon testing… as Shad and I would fly level and at a certain speed, Raphael would zoom past us and go vetical, then pull in behind us and lock us up… All in good fun!
It was a blast testing and having some fun at the same time. Let me know when you want to go up again Shad!
