Suggestion for database, data supply

oh I understand now thanx.
-
Just one more note. All missile weight curretly inaccurate, therefore their drag model eighter. They are heavier as should be. In deacceleration phase the loss of momentum is to low because of bigger weight. If you just lower the weight keeping the current burnout / total weight ration the thurst also have to be scaled down because it was set was too big weight. IMHO its worth the work.
(I can show in a video what the problem is.)
-
is there somewhere that i can get all these changes in like one dat file. Because i love what you are changing but i am not a programer and i really dont want to break my game trying to change what ever it is you are chaning. So was just wandering if there was something i could download that would drag and drop
nevermind im an Idot…been watching this thread but i didnt read up a bit to see that you put instructions to drop in. Sorry

RL thrust and weight data.
BMS4 data comes soon.
Me like’s,my friend……
Your getting better at transposing\manipulating the RL Data into something the SIM understand’s…!!!;)
I assume this update’s your 2010 work???

Interisting stuff Molny!
Could you upload the datfile for the AIM-54?Chrs,
Tom
PS: And all F-15 modded datfiles you have? F-15Cs in Falcon (FF, BMS) behave like bricks as soon as a certain speed and AOA limit is reached. I also noticed the F-15C/E and F/A-18E roll way faster than the Mirages under the conditions I checked. Is that intended? Or is my controller psychic
-
Ops, I forgot upload AIM-54s data. I will upload today.
aim54.dat
aim54a.dat
aim7f.dat -
And the F-15C FM change, if you want?;)
Cheers,
Tom

All F-15 dat file have been uploaded weeks ago. AoA is limited to 20 deg, but maybe it should be 21 or 22. It is very easy to change the AoA, just open the file with any text edtior and change the value.
-
-
Yes, all got the flare and AoA tweak. AIM-54s and AIM-7F dat file are available.
-
can you also zip all the files you uploaded into 1 big db file so that i dont have to download all the different version with?
tumbs up, nice job -
Becuase stuff always updated if I upload today something it will be outdated in after next update.
Here is the pack.

http://www.mediafire.com/?rvu3mhzxirrrpt6why not use dropbox, then you can share your files and update them on the fly in the dropbox cloud (2gb) free

SA-2. (S-75 Volhov)
20DSzU V-755 missle performance
On X axis you can see the time after launch. On Y axis you can see two data. Distance from launch point - my guess calculated flight path distance from speed - and speed. For one test launch you can see two paramtric curves, one for speed and one for distance. The paramteri is Epsilon. Epslion means the constant angle which was hold by the missile during the measurement.
So, the test was conducted by this way. Missile was launched a certain angle and during the whole measured flight path missile hold this angle.
On the last diagram you can see the “available G”, it hould be mixed with upper diagrams to see in which speed range and alt how big G is possible more the missile.
–------------------------------------------------------Missile data
Weight of 1st stage: 1008 kg (2380 lb)
Weight of 2st stage: 1390 kg (3060 lb)
Weight of propellant in 2nd stage: 169,5 + 545 kg (1580 lb) TG02 fuel + AK-20 oxidyzerThe 1st (booster) stage accelerates the missle about 520-550 m/s regardless of circumstances.
1st stage burn time is 3 seconds.
2nd stage have two different program for engine thurst.
1. If Epsilon is small than 24° in the moment of launch the thrust is 3500 kg (~7720 lbs) for 45 seconds.
2. If Epsilon ε>=24 in the moment of launch thrust is 3500 kg (~7720 lbs) to 24 second then 2000 kg (~5510 lbs) to 55 seconds.
–------------------------------------------------------Modeling issues
Because Falcon is able to simulate only one thrust characterisic we have to select one. I will make a table with ranges and altitudes to determine which is the more typical Epsilon in Falcon’s world. This mean for validation only fro one Epsilon range can be correct… (Bigger 24 or smaller than 24 degrees.)
Other issue is the booster stage. Falcon cannot model the weight loss of 1st stage. Therefore missile weight have to be set only for 2nd stage and thrust of booster stage have to be set as way to get the ~550 m/s speed after 3 second. The more accurate modeling of second stage is the goal.
Epsilon depending on distance (land, projected distrance) and altitude.
Valu is 1 if Epsilon bigger than 24 degrees.
Epsilon typically is smaller than 24 degrees therefore 1st thrust model should be adopted.
Here is the table that I used.

Plan for verification
What is the problem? Even for thest I have to make changes in SA-2’s dat file - to get the consant fligt path -to test its performance, I have to reproduce somehow the RL test. I have some ideas how can be done.
After these only patience skills are required to measure the effect of changes.

we are going to a MolnyBMS which is supercool!!!
you are the man m8…QT
-
and just like a noob…where should i unrar those qute .dat files??
QT
-
Thanks Molny! I am too lazy and uninformed to research myself, but I trust you on those items, especially liked the missile drop behaviour you showed. Will check ingame.
-
FYI the missile dropping before igniting is not always missile-specific. For example the AIM-120 does not drop when launched from an F-16, but it will drop when launched from the belly of an F-15. I think there was a thread on F-16.net about this.
-
Thank you! I also like to check how AIM-7s will behave.
Cheers

yeah same goes for the RAPTOR also…
