Rocket thrust ratios are entirely altitude dependent. Was this converted for an air launch? I provided the formula to do this before if not.
1- This is a mass production commercial / military rocket.
2- NASA’s rockets user handbook as the name suggests would have typical and representative values intended to be useful to its intended audience (engineers and scientists who want to choose an appropriate motor for their application / experiment)
As far as the conditions go we only know it’s based on launch from ground.
But there is no reason to think that the launch conditions are different between two revisions of the exact same handbook, when there is no such indication.
Obviously not.
This is a reference handbook
I am surprised this isn’t already in game. Something I have also not seen accounted for in this conversation. The outgoing thrust does reduce drag on the missile. For artillery and other long range projectiles we did years of experimentation with burn butt projectiles. The biggest problem was getting production to apply the chemical exactly the same every time. By putting a small compound on the back end we could reduce drag in some tests as much as 30%. Same does apply for missiles and I don’t think its accounted for in game.
Also, and again, the formula to increase or decrease thrust based on altitude is relatively simple and would be easy to implement. Then you wouldn’t have to do janky things with the drag to play around with how it performs.
I’ve already forwarded the relevant sources to the tech mods and explained the biased points / overlooked data.

That isn’t true in my experience. Sometimes we are asked to re-eval and then once provided with that information its pushed to get published for whatever reason. Even QC re-checks are asked to be published as empirical data or replacement data. But I didn’t read the report to see why the second test was performed. If it was a second test.
That doesn’t matter, these tests are common on the commercial and .gov side for numerous reasons.
Having worked in this industry I have to say that isn’t always the case. The numbers we provide to the client are always averaged, unless otherwise specified. Which at times they do request peak, percentage of variation, and segmented performance numbers. Sometimes they only want 3, sometimes they want radar tracks broken down into 100 data points. Its all based on what the client wants. We do take that information though and average it when comparing to other systems.
Edit: We provide the supersonic, transonic, and subsonic data separate but it is averaged for each one unless otherwise specified. Including the 6 DOF predictive modeling to see how it compared to the real world flight data. Tests are often repeated with reduced charges to gather transonic and subsonic additional data. That transition can be hell at times.
When I get a little more free time I will reach out and ask.
Have you actually looked at the handbook?
It’s not a casual one time report.
It’s a reference handbook with typical values that has been maintained and revised over the years.
2023 revision: https://sites.wff.nasa.gov/code810/files/SRHB.pdf
2005 revision: https://snebulos.mit.edu/projects/reference/NASA-Generic/810-HB-SRP.pdf
It’s not “a” test.
It’s a reference handbook.
No really
You basically sent your biased take on it, guesstimating thrust from acceleration charts with unknown variables such as drag. While ignoring the NASA handbook and the study that actually provide the average thrust value.
All I did was share all of the sources thus far, state only what they say for thrust and burn time and then show that the specific impulse of the NASA sources if they were “average” thrust is actually too high to be accurate.
These are average numbers for multiple launches. However, you cannot skip over that they used a 3:1 Ogive and that is important. The Aim-54s use a 2.2:1 roughly. Meaning the test rocket had more drag off the bat. Probably off topic but this is important.
This matters fyi.
So no one has any thoughts on this?
I’m assuming it’s WIP
There is no reason why you would be able to carry Sedjils on the wing pylon but but Fakour.
In fact test fire videos that are available show it being fired from the wing pylon.

Also:
Sedjil missile wrong designation (should be “AIM-23C Sedjeel”)

It can carry 6, if they don’t allow it then its for bias reasons.
Well, technically we are not sure if the under belly pylons can carry 4x Fakours, 2x or none.
Though I think at least 2x can be assumed.
(Fakour is a heavier longer missile compared to AIM-54)
If the upgrades are correct, you can carry 6. But that space is usually reserved for dogfighting missiles since you want to get most of your weight centerline. BVR off the wings is the better take.
Like this one
It’s not clear which if any of the test footage available is from the actual Fakour-90 rather than the AD-40A export offering which lacks the boost stage and is lighter.
For example you have this video which seems like an official video from the Airforce (Nahaja):
The Persian text says: “Testing of Fakour 90 air to air missile”
But then the English text under it says “AD-40A” which is the much lighter sustainer-only export offering version.
It’s not clear if those are even Fakour missiles.
It’s an old photo (might even be from before Fakour was a thing) and early Fakour productions were colored yellow (Likely to fit the desert camo better).
