ЗВП прототипа соответствовать ЗВП ракеты Meteor…по документации Вымпела

 

 

 

85 километров на 15000м?

 

Только что проверил, для полности тупую цель в автопилотом в игре, такой пуск Р-77 только возможно со скоростях М1.55+.

И не верится что РВВ-АЕ без лофта, столько летчиков, техников говорило что там лофт есть.

Сколько?

Столько флотов других стран с ней летает, зачем ее было брать тогда если есть р27эр? И что же получается, плохие русские всех обманули, в буклетах указали 80 км, а она на 50 летает. Почти в два раза.

Она может и на 80, в стратосфере и на скоростях пуска 2М.

"Дерганье" это тоже маневр. Ракеты способны развивать большие перегрузки и для человека это будет выглядеть как дерганье.

а вот это самое "дерганье" на видео - это ракета на НЛО наводится? я чет не пойму траекторию цели, для перехвата которой такие маневры нужны?

105км для р27эр  для таких же условий? или везде маркетинг и реклама?

я знаю, пробовал) я имею ввиду про буклеты. 80 для р 77 и 105 для р27эр, для одинаковых условий? всегда 11-12км высота и скорость больше 2 махов?

По буклетам вопрос точно не ко мне.

Fuel mass and if possible rocket motor configuration and burn time.


У нас разве есть данные по Р-77 и амрааму? Это не издевка, я просто не в курсе и не встречал такой информации (как минимум массу топлива) по этим ракетам. Касательно времени горения - ну тут документация не является определяющим фактором: вспомним изменения Р-27

I think it is a fair question.

 

Here's what we have:

 

R-77:  Fuel mass from same documentation as R-27

AIM-120A/B/C1-5:  A document that lists the explosive content of ammunition for the purposes of safe storage and fire-fighting lists the propellant masses for those missiles.   Also for AIM7/9/54, certain SAMs I think and some AGMs as well.   The rocket propellant mass is listed separately from warheads etc.

 

We have had this documentation for years now, first posted here in this thread, but I do not recall by who.

 

The weaknesses in this documentation is that the burning time, and especially for multiple-grain configuration is not known, only the total mass.  But it reduces guessing by a lot - now you only have to guess ISP and burn time for each propellant grain, and there are some basic rules for those, including the fraction of boost:sustain grain.

На 77-1 не хватает всего.

and what does this documentation say about the loft?

That particular documentation has nothing at all to do with the missile's flight physics, it is fire/explosion safety documentation.  The one for the R-77, I don't know but I assume it doesn't say much.

It's the weapons employment manuals for the F-15 and F-16 which specify that the AIM-120 will loft (as well as AIM-7MH and later, although the loft is different from that of the AIM-120 AFAIK).

Ну здесь только руководство по су 30 сможет помочь, или каком ни будь  экспортном борту. А вы GGTharos , как считаете есть лофт у р77? 😀

Unfortunately I don't have such a document 🙂

 

As for what I think, this missile is new enough where lofting would be a 'standard feature' for most AAMs (It had already been a feature of SAMs).   It was a surprise to me to hear that it does not loft.

Да для вас не одного было это неожиданностью, много людей было удивлено что ED считает что у р77 нет лофта. Тем более обещали весной сделать.

Может цель отбрасывает диполи и ракета на них соблазняется? Немного похоже.

Are there any charts regarding the Meteor missile? Will it be based on pure fantasy?

I know there are some very detailed studies out there from various groups about the most probable inner workings of the meteor.  Its as close as were going to get to the actual stats for at least 40 years.

No, but as long as certain data and science is available it can be based on a well educated estimate.

Which DRFM jamming modes can interrupt the datalink of that missile? What happens when the fighter AESA looses track for 20 seconds and then finds the target again? What happens if it is launched from slow speed? What are the seeker gimbals? What is the seeker range, and how does that change against DRFM jammers?

None.  Guess why.

Does it?   Can it?   But anyway it's a MESA that we'll get, AFAIK.   And what do you think happens anyway?

Same thing that happens with any other missile ... it speeds up.  The gimbals can be reasonably guessed at to be 50-60 degrees, seeker range can be the same as the 120 and I'm not sure what your obsession with DRFM jammers is, because you're not in danger of being equipped with one.

That sort of stuff is the environment the missile works in. Heavily jammed. And the meteor can only be fired from Eurofighters with AESA radars.

Its a rhethorical question, because all that info that drives 4++ and 5th gen combat, is not public. Thus a realistic implementation of Meteor in DCS is not possible.

Unless you want to just point and click 1980s MiGs. But might aswell shoot down airliners then, the level of resistance is about the same. Infact, the time difference between an older F-16 with sidewinders with and the BF-109 is lower, than the time difference between the Meteor and the introduction of the DCS red aircraft.

A MESA can generate the required signals just as well.

I think we can get pretty close.   There are no DRFM jammers in game, no one's implementing DRFM capability or capability against that in AMRAAM or other modern missiles, including SAMs in DCS.  In DCS, ECM is generic.  That's all there is.

I don't have a problem with that.  Sometimes that's how the mission is.

Splitting hairs here.  I'm not concerned with any type of balance.   If the missile gets in the game, I'd like to see it modeled as close to IRL that we can get as possible.  For online gaming the mission maker can remove the METEOR from inventory.
