it’s in russian though, just a warning, i just used a machine translator.
also for any source i post you can just ask me to provide it to you, i dont mind sharing files to anyone unless the person who gave it to me explicitly said to not share them
My brother in christ i am a native speaker :)

Oh lmao never realized that

did some calculations with that value for the c5 and it would increase delta V by 40-70m/s given that, the nerf to the r-77-1 would be like aprox 5-15m/s
6 m/s nerf for R77 , 70 m/s buff for aim120c5. (if the weight of propellant is constant)
100s of burn time is crazy, ngl
i ran a sim on stat shark the r77 would be like 3 seconds slower time to target at 60km with corrected motor output compared to its current state

Alright, here’s some information on r-77 homing head. I would assume a lot of other fox 3s employ similar methods as this. This is from the Russian magazine Крылья Родины which the r-77 patent refers to as a reference point for the missile.
Before launch
About 10 seconds before entering the authorized launch zone, the rocket starts operating in “pre-launch mode” and recieves information about the target from carrier.
At the command “start”, the automatic power is turned on, and information about the target is stored in the missile and the fins are unlocked. They are given a preliminary deviation from the carrier in order to safely separate from the carrier.
If located on a rail launcher, then the engine is ignited immediately. If located on an ejection launcher, then the pushrods are triggered first, separating the rocket from the aircraft, and then after a delay, the engine is ignited.
If target is in the case of “minimum range” of when seeker head is to activate, then missile goes active immediately.

During flight
Missile guidance is a combination of both inertial and active radar homing at the final section of the trajectory.
The transition to the latter is carried out by the signal of the on board computer, which determines the distance of the target with the homing head.
After the missile switches to active radar homing, the correction line of the missiles flight data form the carrier continues to form a mathematical model of the target.
In case of loss on the trajectory, a re-searching of the target is done using this model.
In all application modes, the method of modified proportional guidance is used. And in conditions of organized interference, in which the onboard wearer can provide missile guidance of the direction and approach speeds for the target, guidance occurs along special trajectories.
The missile also employs the ability to passively aim at a source combined with a target.

My thoughts
Thoughts on how this is modeled in wt:
-
IMO, it seems like this missile has contant datalink with the aircraft, even after the missile seekerhead locks onto its target. This should enable the ability to relock the target for the missile if it loses track and if host aircraft manages to keep track of target. Currently, this only happens if the target is in “look down” when IOG+DL will be activated, if target is in look up, it will not use IOG+DL and will simply lose target if they notch it early.
-
The missile loses datalink if the host radar switches radar mode, which idk if irl will make it lose datalink with aircraft, but in WT it does.
-
It seems like fins should be activated right off the rail in wt when rail launched. IK other missiles like amraam also activate the fins right off the rail IRL when rail launched, but in game all fox 3s seem to be modeled with their ejector launch fin delay.

Holy shit I literally could never find a image of the R–77 with the ramjet anywhere whatsoever, how’d you get this?

does the ramjet give significant range increase or is it just a gimmick?
It more than doubled the range over original rvv-ae so it’s certainly not a gimmick.
120 km launch range against fighter type targets,
Up to 180 km launch against awacs type targets
isn’t that just the alleged same range of the K-77M/R-77M?
Keep in mind though it’s quite a bit heavier than either r-77 or r-77-1.
So it’s not like some super missile.
Around 30 kilos heavier than r-77-1
Izd 180 doesn’t have any published launch ranges as far as I can tell other than being up to 3 times as much range than rvv-ae.
interesting, I’ve always wondered if China surpassed russia entirely when it came to BVR, seemingly the PL-15 has some pretty monster range to it.
Pl-15 is most likely superior to izd-180 anyways.
We got published g load and range figures for at least the export model
wouldn’t it be safe to assume that the production mod has more range than the export mod?
