Well not exactly, I rather consider this work of mine not close precise to what should be or what nomograms present. Not surprisingly with so much assumptions. With same principles I tried with R-27R as well. And it is different in way of shooting in PPS. Seams that for R-27R higher available overload margins are given what is reasonable and explainable. In ZPS more or less same principle as in case of ER. Nomograms about maximal distances of the rockets from the fighters after launching are however still big mistery, at least to me. I don’t get those at all what doesn’t mean they are wrong.

@Max1mus When I said comments of any kind, I still thought on reasonable comments

And by the way, rocket having such wings near to the center of gravity usually and by purpose doesn’t do high angle of attack compared to others. I doubt is it even 10 in this particular case.

All right, Cy function to get down a bit and to have Cn with 17 deg at time when needed. Fact is that obtaining of horizontal flight is with reasonable angles much under 12 or 17 so increased or reduced Cy will not affect a lot induced Delta Cx and by that velocity in function of time.

Спасибо Маэстро ! It is true, not precise, not truly correct, but still it should be matter of percentages, percentages in level under 5, not more than that. Pick value is at 1,1 Mach number, it is as it is and we can’t change it a lot or at all. There you have 0,05 which converted to cross section makes Cx 1,08 or i58 1,72 what is huge taking in consideration that R-27R is with all its aerodynamic disadvantages still nicely done. While making step by step calculation, I’m still getting Cx 0,875 at 1,1 M or i58 1,4 and all that at 10km altitude where friction is higher. Coefficient i58 is what I use and although it seems irrelevant, for flights of 60 seconds long especially down under slightly increased Cx makes a lot of changes. In that 0,875 friction of the body makes 18%, nose pressure 21%, bottom pressure 27%, and rest 34% is friction and pressure at wings. What ever try to disadvantage, Cx 1,08 is far a way. Don’t take me wrong, I have no intentions whatsoever to change anything, just expressing my thoughts. In any case this new Cx function is significant improvement compared to previous function which at least as per my humble opinion was horrible

Fuel block (in my perspective) has крестообразный канал all way long but perimeter is not same. Front side is substaining and highly boost assisting, rear side simple as that boosting only and middle differential is key for everything to have what expected.

Мне кажется что ты не понимаешь сущность внутренней баллистики ракетного двигателя.

Некоторые данные известные от ранее или нет, но в любом случае... Р-73 Масса снаряженного двигателя: 56,4 кг Масса заряда: 34 кг Время работы двигателя (полное) : 4,1 - 6,8 с Допустимая перегрузка ракеты: 50 Суммарный импульс: мин 7600 кг Р-27Р(Т) Масса снаряженного двигателя: 96,5 кг Масса заряда: 60 кг Время работы двигателя (полное) : 4,6 - 7,5 с Допустимая перегрузка ракеты: 40

ЗСУ Су-25 х-25мл - YouTube Ирбис из Рязани. Irbis from Ryazan. - YouTube Two phenomenal videos showing vertical gorka manoeuvres of Kh-29 (seams L) and Kh-25ML. On those rockets (for 25ML for sure) principles are a bit different, line of sight toward target is moveable and gorka ends with ''razvarot'' .. don't know how to translate...when angle between line of sight and horizont close 27 degrees.

it is very hard to convince you, but all right, we don't need to think same. There are of course documents which confirm this, book well know to all and some other papers. This trajectory is result of mathematical algorithm and how rocket is guided in inertial phase of the flight, in related altitude ratios, and nothing more and nothing less. Reading between lines is very important for understanding of essence By the way, in same video just after R-27 you can see R-77 doing same

BlackPixxel...it is just rough graphic, not in scale, not in time line. In nature it should looks much more smooth. As in video from previous page you published, that should not be shooting high flying target but exactly this what we are talking about. You remind me on someone, ''if it doesn't state in manual for pilots it doesn't exist''
