2609*9,81*3,5/23,5=3812 -> not correct, too much 2609*9,81*3,5/37,6=2382 -> seams correct but not for composite with aluminum in it. This rate is more for good nitrocellulose-nitroglycerin double based fuel grades. Whit converting this Isp to nominal or specific or удельный at ratio 40:1 atmospheres as usually fuel data are given it drops to 2255 Ns/kg. Widely used double based RNDSI-5K is given with 2186 for comparison. If you have layout, cutoff drawing of this motor we can go in other direction and by geometry, burning rate and by common criterium to determine seconds.

Thanks @nighthawk2174 ... good points It makes sense now, not only 4900 s was absolute fiction but also 1325 s for second phase which is under any normality. 2608*9,81*4,5/37,6=3062 s ... wow ... what a coincidence, same in single digit

“Fluent phrases”… “This is natural. AMRAAM is the best missile in the world.” “Р-60 сложно назвать удачной ракетой.” “Оригинальная AIM-7F позволяла F-15A обстреливать МиГ-23 с 50 км.” сказал инженер конструктор

Korolev, Isaev, Ermakov, Shipunov, Bunkin, Nepobedimy, Grushin, Toropov…and dozens of other brilliant engineers are turning in graves right now. After all they gave and done, there are now some who will deny all their successes…ccc

The most humans annually killed by some animal is killed by mosquitoes…so mosquito is deadliest animal on earth! I just smashed one annoying me. That is something similar to this quote that AIM-120 is the greatest.

Don’t know @BlackPixxel what more I read about it less and less I understand. What I can’t draw, that I don’t understand and this I can’t. Could maybe but can’t accept that rocket of 80’s doesn’t moved a millimeter from others decades before. All right, INS and RK is involved but in same that time in others as well and with much more efficient trajectories.

Если у ракеты есть фаза инерционного наведения, а у Р-77 она есть, как и у Р-27Р (ЭР), то траектория имеет форму горка или лофта, как вы говорите

Это все нормально, в этих графиках рефератная поверхность =поверхность мидельа ракеты, 260/230мм

Circular ellipse is perhaps of mixing ET and ER
