Does gaijin consider this book as a legitimate source?
idk ill find out when they answer this bug report. its been recommended by bbrcrf if you know who that is so i trust it

Seems you got cucked with “not enough data”
yeah just one secondary source. need 2 then, ill find one from a magazine or something
Ngl if implemented it will be pretty huge buff to 29SMT and 30SM (if gaijin gonna tread 77-1 same way) with their insane gimbal limits

771 already has ±180 launch limits along with mica. I’m tying to get base r77 to have that as well
Really? I guess I haven’t been in a situation when it was required. Also aren’t 77 and 77-1 use same seeker? Iirc -1 upgrades were aerodynamics, battery life and a bit more engine.
R-77-1 irl has a newer seekerhead but in game it’s identical to normal r77 and all other fox 3s other than phoenix and mica
Any publicly known figures for that seeker? Would be great to have something to base a report on for it, as I hope and expect that MICA’s won’t be the only privileged missile anymore for the foreseeable future…
I only found the names. R-77 uses 9B-1348 (RVV-AE 9B1348E), R-77-1 uses 9B-1103M.
Agat also showed in 2014 9B-1103M-200PS and 9B-1103M-200PA with additional passive and semi-active channels accordingly for Izd 170-1 and 180 missiles but it is unknown if they are used.

Found a pdf of this one, gonna read it during free time
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 :)

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.
