Need Help with russian text.

" Дальность обнаружения истребителя на максимальном режиме работы двигателей на фоне чистого неба в ЗПС под ракурсом 0/4 – 2/4 составляет около 50 км, на фоне облачности, земли и водной поверхности 20 – 35 км, а на форсажном режиме работы двигателей в ППС под ракурсом 1/4 составляет 90 – 100 км."

my translation

Seeking distance for target "fighter plane" with maximal throttle and clear sky background in FHS with aspect 0/4-2/4 valued near 50 km, with cloudy, ground or water(seas,lakes etc) background it's near 20-35 kilometres and with active target's afterburner in FHS with aspect 1/4 detect distance valued 90-100 km

with active target's afterburner in FHS with aspect 1/4 detect distance valued 90-100 km

This was very surprising the first time i had saw. 90-100 Km ¡¡¡¡ Detecting range in ЭПС ¡¡¡¡

Is possible for the EOS to detect so far an objective in afterburners? I dont think so and i dont understand why the afterburner mode could extend the RADAR detection distance. This would have effect only to EOS, not the RLPK detection range.

Hmm..... now I'm surprised too

maybe the manual descripts about combined EOS-RLPK use....

PS with active AB the engine's turbine rotors are rotating veryveryvery fast and they're enlarging plane's radioemission-reflectibility %]

Here we go again.

Now is the turn of the Su-27 gun. ВПУ in russian.

It has two operational modes:

НЕСИНХРОННАЯ СТРЕЛЬБА. This is the mode when you have target lock and range measurement.

ПРОГНОЗ-ДОРОЖКА . This mode is when you do not have both ( neither lock nor range measurement )

The first expression are translated like " Non synchronous shooting ". The second like " Forecast the path "

Someone could help me with a more english suited translation? Because non synchronous shooting in a mode where all are very synchronized do not fit very well ( you have lock on, range to target and a point of impact calculated all the time.

The other expression fits better, because the pilot needs to " forecast the path " of the bullets to the target.

Thanks in advance

Несинхронная стрельба - means you have target lock, and your ballistic computer can tell you where your shells will be. You don't have to go at target's 6 o'clock and synchronize with it.

Прогноз-дорожка - you have targeting marks, prognosing how much shells will deviate from initial shooting direction with a distance. In this mode you must go to target's 6 o'clock position, synchronize with it's list (keep the same) and place target's wings on targeting side lines.

Allright Dragony. The sync or not sync is about the relative position of both planes.

Now i understand the reason why the manual uses the expression " Asyncrhonous "

Thanks a lot.

Another text, mates.

В режиме ППО при атаке цели в ППС целеуказания (ЦУ) и разовые команды (РК) подготовки к пуску ракет Р-27ЭР1 (Р1), Р-27ЭТ1 (Т1) выдаются сразу при захвате цели РЛПК или ОЭПС, в ЗПС – за 5-7 сек до максимальной разрешенной дальности пуска.

Here the problem is целеуказания (ЦУ) and разовые команды (РК).

The first expression is translated like " aim designation ", the second like " single command "

What this means? first the lock of the target (ЦУ), and then the guide mode of a single missile?

Thanks in advance again.

Hmm..... now I'm surprised too

I believe the manual describes the functionality of the SUV-27 - i.e. the Weapons Control System(WCS).

The WCS is the overall pilot interface for the combat systems, which controls all sensors(radar, EOS) and weapons employment.

целеуказание(ЦУ) - means targeting, sighting.

разовые команды in this situation could mean "momental commands", the text says about WCS sending targeting commands into a missile.

This affirmation " Дальность обнаружения истребителя на максимальном режиме работы двигателей на фоне чистого неба в ЗПС под ракурсом 0/4 – 2/4 составляет около 50 км, на фоне облачности, земли и водной поверхности 20 – 35 км, а на форсажном режиме работы двигателей в ППС под ракурсом 1/4 составляет 90 – 100 км." are in the ОЭПС description inside CYB chapter. Is a great surprise to read that the ОЭПС could see a target in encounter mode at such great range.

To Viper_srd, the new sentence is in the section " Special characteristics about CYB in ППО and НПО conditions "

This is the whole text in both conditions.

"В режиме ППО при атаке цели в ППС целеуказания (ЦУ) и разовые команды (РК) подготовки к пуску ракет Р-27ЭР1 (Р1), Р-27ЭТ1 (Т1) выдаются сразу при захвате цели РЛПК или ОЭПС, в ЗПС – за 5-7 сек до максимальной разрешённой дальности пуска.

В режиме НПО ЦУ и разовые команды подготовки к пуску ракет Р-27ЭР1 (Р1), Р-27ЭТ1 (Т1) выдаются сразу при захвате цели РЛПК или ОЭПС при атаке в ППС и ЗПС."

разовые команды (РК) could means that after target adquisition the CYB deliver orders and indications of the missiles readiness for launch it and displayed it in the HUD?

"В режиме ППО при атаке цели в ППС целеуказания (ЦУ) и разовые команды (РК) подготовки к пуску ракет Р-27ЭР1 (Р1), Р-27ЭТ1 (Т1) выдаются сразу при захвате цели РЛПК или ОЭПС, в ЗПС – за 5-7 сек до максимальной разрешённой дальности пуска.

In CIS mode (complete instrumental support) while attacking target in FHS target designation (targeting information) and launch prepare signals are passed to R-27(E)R/T(1) missiles at the moment of target acquisition by RLPK or EOTS; when attacking target in AFS (target's, not yours) - 5-7 seconds before maximum launch distance reached.

In IIS mode (incomplete instrumental support) it is passed at the moment of target acquisition regardless of hemisphere.

Well I must admit I didn't read the whole thread through, so I might have misunderstood something, but my reply to Viper_svrd was another reflection on what you wrote:

This was very surprising the first time i had saw. 90-100 Km ¡¡¡¡ Detecting range in ЭПС ¡¡¡¡

 

Is possible for the EOS to detect so far an objective in afterburners? I dont think so..

It think it should be possible for the EOS to detect an afterburning target at such ranges provided all conditions are optimal - i.e rear aspect with a clear line of sight to the AB engines against clear sky, but...

...and i dont understand why the afterburner mode could extend the RADAR detection distance. This would have effect only to EOS, not the RLPK detection range.

....you are right that this of course doesn't help the radar in any way - on the contrary the radar will have a much reduced range in the conditions(rear aspect) that are optimal for the EOS.

So if the paragraph you quoted was stated specifically in connection with Encounter mode, then it must be a case of using EOS in combination with or as an alternative to the radar(due to the above) as Viper_svrd suggested - and since this involves two separate sensor types the paragraph must describe a function of the SUV rather than a dedicated radar(PRF) mode.

Thanks both of you. You are very kind, great support by russian side ¡¡¡

Now i understand it clear.

Target Designation and Launch Prepare Signal. This help me a lot to improve the translation because babelfish or other sources dont help me ever i want.

And my mistake.... 90 - 100 km detection range is not in ЗПС is in ППС by the ОЭПС in single and primary channel. ( RLPK not working at all )." а на форсажном режиме работы двигателей в ППС под ракурсом 1/4 составляет 90 – 100 км." I had mixed radar and EOS working when the manual only talks about ОЭПС characteristics. And also when i had read ППС i associated it to a radar mode forgetting that in EOS are also a ППС mode.

But the question remains,is very strange in ЗПС the detection range is 50 km in optimal conditions, and 20-35 km when clouds, sea or mountains are present. And in ППС in afterburning modes 90-100 KM. Maybe a manual mistake, greater detection range in encounter ( but with afterburners ) than in pursuit.

working afterburners increases IR signature 2-3 times, so even in front hemisphere afterburners keep it's big unmasking effect.

But the question remains,is very strange in ЗПС the detection range is 50 km in optimal conditions, and 20-35 km when clouds, sea or mountains are present. And in ППС in afterburning modes 90-100 KM. Maybe a manual mistake, greater detection range in encounter ( but with afterburners ) than in pursuit.

"Maximal" engine thrust means "military", 100% RPM w/out AB.

Yes i know.

There are two " maximal " engine modes. Maximal Combat engine thrust ( 100% w/o AB ) and Maximal Training Mode.

And another two with AB. Combat and Training.

The 50 km range detection in ЗПС is in maximal combat engine thrust w/o AB. and the 90-100 detection range is in ППС with AB.

So what's the question?

W/o AB: FHS: 10-20km RHS: 20-50km

W/ AB: FHS: 30-90km RHS: 50-180km

Dont' see any mistake.

In one post i had said " This was very surprising the first time i had saw. 90-100 Km ¡¡¡¡ Detecting range in ЭПС ¡¡¡¡ " when the correct is ППС.

And the strange thing is that in a section of the manual where only are described the EOS characteristics ( without RLPK in back up channel ) said that in FHS with afterburners the detecion range is 90-100 Km and this is to much in my oppinion. More detection range in FHS than in RHS, ( only 50 km in ideal conditions w/o AB or 20-30 with sea level, clouds etc ).

Sorry, for my english, low level english and with the problem of a third sides translation ( russian - english - spanish ). Sometimes i get blurred.

Here we go again.

"При работе в ЗПС на фоне земли при типе цели МЦ и Н < 3 км "

Working in RHS against earth background and МЦ type of target and Height less than 3 km "

What is МЦ? многоцелевого ? Multirole ?

This sentence is here, in this table and again need help with abreviatures.

What is the meaning of:

HH HЦ and HП ? Initial Altitude, Target alttitude and Launch Alttitude?

In the manual Высота is always reffered like H, and then Hh = Набора Высота Нц= целью Высота and Hп= Пуск Высота ?

And in the max G for launching whats the meaning of BCY?

Bumb...

Thanks

¡Hola!

If you still interesting… And my apologies for editing your posts in my citations.

Here we go again.

 

"При работе в ЗПС на фоне земли при типе цели МЦ и Н < 3 км."

 

Working in RHS against earth background and МЦ type of target and Height less than 3 km "

 

What is МЦ? многоцелевого? Multirole?

Perhaps, МЦ — маневренная/маневрирующая цель — maneuvering target.

This sentence is here, in this table and again need help with abreviatures.

 

What is the meaning of:

 

Hн, Hц, and Hп? Initial Altitude, Target alttitude and Launch Alttitude? - Correct.

 

In the manual "Высота" is always reffered like H, and then Hн = "начальная высота" (misprinting Hп?), Нц = "высота цели", and Hп = "высота пуска"?

 

And in the max G for launching whats the meaning of ВСУ?

 

I think the table 5.1.11 - and the whole manual, actually - have a lot of the misprintings. Plus DejaVu format artefacts.

Row 4, 1st column: Диапазон высоты полёта целей -> Диапазон высоты полёта целей, м

Row 4, 2nd column: 20-2000 -> 20-20000

…and so on.

"0-5 с ВСУ" means "0-5 g's when launch missiles from pylons #7 and #8." (look p. 169 and you find ВСУ in company with АПУ and АКУ).

Missed the thread renewal...

HH HЦ and HП

"Hн" = "Height of the shooter" (H is a common height designation, "н" stands for "носитель")

"Нц" = "Height of the target" (ц=цели)

"Нп" = "Launch height"

But you've already got the idea.

"МЦ" ("малая цель") is target RCS class, "small" is ~1-3m^2.

Thanks both of you.

I appreciated very much your help.

Namenlos Ein. You are killing me telling that the manual is full of mistakes ¡¡¡¡ With my little intuition capacity i could found several incorrections. When i had tried to translate several words and the translator could not do it, often is because missprinting in the doc or this "ë" instead of " e ".

Step by step i could arrange this in several situations but nothing compares to your help and the work of this fantastic russian community.

About BCY. Yes, i think is a pilon, rack or missile support in the wing edges. But if AKУ is "Aвиационное Катапультное Устройство " Aerial Ejection Pylon and AПУ " Aвиационное Пусковое Устройствo " Aerial Launch Rail, what is BCУ ?

Thanks again for your kind support.

ВСУ = Вспомогательная Силовая Установка, Auxiliary Power Unit (APU). It provides compressed air for engine turbostarters, and also can be used for rotating generators without starting engines.
