Suggestion for database, data supply
-
Where you can download any app? This means fine element modeling for 0 speed to supersonic range.
for example FlowVision
also can be useful prodas 2000
and so on. -
How many simulation hours are required for one missile?

About racks and wepons stores. Regardless of available theoretical weapon config I cannot aviod to recoomend restricted confight because of ATO + campaigns. HP confighs in DB are partially subjective this is unavoidable.
I don’t get what you mean exactly… how is ATO involved with what can be loaded on a given rack?
And if you are worried about ATO then the problem is somewhere else and not with racks config etc… if we want to ever anything with DB changes we should start sorting and fixing, and better do the easy stuff first (and IMHO HPs config is one of the simple things, what weapon and how many can go on what station, that should be straight forward change, regardless if ATO is stupid, for example).

Not much.
Get 6-8 Mach number points.
And 8-10 AOA points,between them approximation, will be enough. -
This means 6x8 or 8x10 point, because Mach AND AoA have to be combinated. Do we have exact data about shape of rockets?
-
because Mach AND AoA have to be combinated
Really?
@molnibalage:Do we have exact data about shape of rockets?
You do not know where to get the drawings ore finished 3-D models? I can not help
-
If you wish to modell well the coefficient you need very exact data about dimensions, which are not available from dimensionless blueprints. Small chamfers, edges are counted for CL and CD….
-
So, can you show just a quick demo (speed M2.0 AoA 2 deg) with mentioned sofwared to see how close is the result for current values in DB?

You opened my eyes
I knew it even before the debate began.

No time for it

@OSD & SpbGoro
Does this table contains data which concerning on burn time and help calculate the total impulse?

hi, molnibalage
u talk about missile weight a lot.
i have read 10 pages of this thread without answer: in BMS editor (from launch menu), we can see the weight in weapons>weapons tab and weapons>simweapondata tab, SA-3 has 300 and 225 (unit unknown), and ur dat file is 593 lbs.
do i need to change them? r they really affect in-game exp?the other weird missile is AS4, in DB it is 2000 (unit unknown), but in wiki it is 12000 lbs!
BTW: u can enlarge SA-3 range in BMS editor -
The problem that missile weight is defined depending where it is. If a missile are on a hardpoint its weight is stored in DB, but after launch weight is defined by dat files. –-> Only air launched missile weight is important in DB, for other it does not have effect in their performance.
So if you set for ex. 2000 lbs for AIM-7M in DB, as long as AIM-7M on a HP its weight is 2000 lbs, but after launch the dat file data is used because of changing weight (propellant consumption.)
This “dual world” is also true for drag as I know. You can set as big drag a missile in DB as you wish, but after launch the drag table in the specific dat file is used. This is why I’m saying that DB structure of Falcon is very idiotic and fragmented…
-
I prefer to use program 201, even it is unreal for high altitude targets, but because of the limited engagement distance and bubble it is more suitable against low and high flying tagerst eihter in Falcon’s environment. You can see that against low flying closing target the engagement distance is much smaller.
I believe the missile engine program is dependant of expected point of impact height and missile flying time:
1. Time of flight < 52 sec or T>52 sec and height < 20 km - this which you marked “105”
2. Time of flight >52 sec and height > 20 km - program “201”…Also the flight profile is dependant from the time to impact and target height…
-
I know when is used a certain program, only problem Falcon uses static dat file sturcture.

I see…. Sorry, I just want to help…

Can you clarify that R-33 has dual thrust engine?
-
@SpbGoroCan you clarify that R-33 has dual thrust engine?
Yes - R-33 has dual thrust engine (двухрежимный РДТТ)http://vympelmkb.com/products/prod01/But there are no detailed data on this engine.I think - the data on the total impuls and power - are similar or close to the AIM-54A
-
I set the same total impulse for AIM-54A and R-33 (~85000 lb*sec), but AIM-54A has constant 3200 lbs thrust for 27 sec except a 3 sec transition from 0 to 3200 lbs. What about AIM-54C. You have posted that AIM-54C propellant weight is smaller than AIM-54A’s. What about thrust characteristics and total impulse?
-

Fuel weight table:
“MXU-637/B” for the AIM-54A as containing 459 lbs propellant,
and “MXU-637A/B” for the AIM-54C as containing 360 lbs propellant.
Aim-54A: weight – 453 kg. Max Range – 3,7-130 km , Max speed (4,3М or 4800 km/h), Max lofting altitude - 24,8 km.
Aim-54C: weight – 462 kg. Max Range – 150 km , Max speed (5М), Max lofting altitude - 30,5 km.
Presumably, an increase in range achieved by the use of more advanced lofting trajectories and > speed.
More likely, in the fuel data table for a misprint, because there is a total mass of the missile > higher than (A), but the weight of the electronics should be less than, due to the released space increase the share of fuel.Here, asked a similar question http://www.secretprojects.co.uk/forum/index.php?topic=15336.0
