That page completely breaks down and describes each section & it's function in the aircraft.cfg file.


Very handy. 


I've been tweaking on the JBizz .cfg for more speed, I swapped in the engine section from a Mig-27, plenty of speed and power now, just need to get the COG correct for them.   

ive already gotten the warnings to wait longer, and if you want I could take what you have current and work in my adjustments and see what happens for that, I also got two custom paint schemes done up that need some minor fine tuning also...and other then that its really shaping up to be a great plane!


@Shane: I used the engine specs more of what an F-4 would use (i think I went more along the lines of the J series) since the F-4 phantom used the same type of engines that I think the Jbiz jet is supposedly using....least that's from my understanding and also based on the way the engine pieces are modeled...


@Jakes: I did adjust one of my textures so that way each part is labeled (I can send you the plane with the texture so you can see what i'm talking about or a screen shot if that helps) the tail does need to be remapped so the left side is mapped to the correct image since it is mapped to the same image as the right side, just so you know. I may need to show you a picture since its a bit hard to fully explain...but other then that it is really turning out to be a great plane to fly!


Oh and how does Mach 1.16 sound as full speed cruise? (throttles fire walled)

the Proof that its red lining at 1.16 at full throttle...now I just need to fine tune the stall out speeds and that should get the plane in order...and what speed are you looking to "over speed" at? I have it set to "over speed" at 900.0 KIAS as of the screen shot (second test at 50,000 AGL) and its holding right around the speed indicated in the shot also...level...

she can hold M1.10 -1.12 at 50,000ft AGL...so I would guess this meets your requirements of M1.6 cruise?


though you got to hold the throttles near 70 - 90% to get it to retain M1.11 at 50,000 but thats also partly due to the thinner atmosphear at the altitude, so after I run two or three more tests I think it will be good to go (yea Im picky and won't hand you the updates till Ive confirmed that its able to do what you want it to do and pass with flying colors), but as for the new updates textures, not a big deal, the ones I hammered were done as a test bed idea anyways and so I could have at least two versions to use when I needed to reload the CFG (when you reload either variant, even the same one, it will read the CFG and take the most current settings).

but as I said after a test or two and some possible fine tuning I think it should be ready for you to get it into the updated version, and if its ok could I get the updated version with the remapped textures so I can start reworking mine so they will fit correctly? and how would you want me to get the updated CFG file to ya? (PM me for how you want it sent to you)


Oh, and since you redid the size that *MIGHT* change the way the plane "handels" so if you want me to I could take the updated version and run some tests to make sure that my CFG will work properly and still achieve the M1.10 cruise speeds it holds at this point.

Main reason is since you made the plane a bit larger, the air file as well as the CFG are going to be different then what I currently have (mine is set up for the smaller version so its going to handel a bit differently then the newer larger version), if the size is not too much difference it may not be effected alot, but I think it may be better if I put in teh settings to test them and rework them to the newer updated plane then I could send that to you and put in the file the area that I edited so that way you can look and see what I did if you want? I just don't want you to accidently copy the CFG (older) I have over the CFG (newer) that you have and spent lots of time working on to get landing lights and that stuff in it and end up loosing work...

Let me know how you want to proceed with this since I would rather made changes to what I have done on the newer file and test to ensure that we still achieve the same results then to be the cause of you loosing all your hard work...or is the "newer" CFG still the same as what I have? (as in no changes)



ok with the current set up of the CFG i got, I can have it take off at full power, then retard the throttles to 50% (+/- 1 - 3%) and its fully capable of climbing to 50,000 on its own, takes about 15 minutes (estamated) but that should be about right for any type of plane, if I keep throttles at 50% (EPR reads 0.51 so im guessing that is telling me that the throttles are at 51% or +1 from half) and it gets up to M1.02 and holds that, which tells me that if throttles are set to around 55% - 60% it should be able to hold M1.06 no issue.

Some stats of the plane as is: (note these may and WILL change with out warning) and are current as of testing on 12/09/2009 at 16:13:00

Service ceiling: 50,000 cruise
Max speed: 600 Knots (estimated)
Cruise: Mach 1.06
Max Mach: 1.16 (full throttle @ 50,000) [not recommended to exceed M1.10]

Max service ceiling: 60,000

ok, thats what I had a feeling happened, should make for a fun plane, expect the CFG with in the next day or so just so you know, gonna do a last minute fine tune and it should be headin up to ya

As a casual observer I would like to comment it is fun to watch you folks work through this whole process. Looks like a great learning experience.

Mach 1.10-1.12 is Mach 1.10-1.12 regardless of altitude and therefore not =M1.6

If my understanding of Mach is correct.

cheers,

JoBee, It is fun indeed. hard work, but fun to see the results. And all is done with the help of the SimV crew!

you can have a look at the progress here

Jaime, thanks, Ive worked a lot on the CFG since, and the resilt is surprising. Will have a new beta model ready early next week 

Hey Jake, where are you at with the speed thing now?  Have you done an accurate measurement of the intake area?  The frontal drag of jet engines is actually quite large and if you have that spec set too high in the CFG, it is like having the brakes on.  For example, I had my intake area too big by .5 sq/ft.  Reducing it that amount took my speed from Mach 1.7 to 1.8!  You could find a lot of speed here – but don’t fudge it. 
There are a few ways to approach the specs issue.  You can copy and paste and just get it flying – even cheating, or you can accurately measure everything off your own 3D drawings just as if it was a real aircraft.   Doing the latter will ultimately be more satisfying since if someone asks you “Could this thing really fly?” you would be able to actually say “YES”  - given the constraints of the game engine.
Stability is going to be a weight and balance issue, but at high speed, the pressure around the airframe moves upsetting the balance, and even yanking your controls form your hands.  Using an all-flying tail is part of the answer for most sonic designs, but Flight Sim 9 (don’t know about X) will not let you have such a tail.  A compromise is to make the Horizontal stabilizer bigger and the elevator smaller but with more deflection, and also lots of trim.
The big question is what is a realistic airframe weight?
