Need Help with russian text.

[Esac_mirmidon]

Sorry for posting here in english but i think this is faster than posting it in the english section.

 

In the Su-27SK manual you can find several notes about different piloting modes that are confusing me.

 

I find three and i want to know if this are really three piloting modes in the SU-27 or maybe iґm making mistakes in the translation.

 

1.- РУЧНОМ УПРАВЛЕНИИ. I think this is the manual mode of piloting.

2.- АВТОМАТИЧЕСКОГО УПРАВЛЕНИЯ. I suppose that this is the automatic pilot. САУ modes.

3.- ДИРЕКТОРНОМ УПРАВЛЕНИИ. This is the problem. I dont know if this mode is the same than the automatic pilot or maybe is a semi autonomous mode of piloting ( maybe a manual mode with some kind of guiding, maybe a manual govern with the aid of the guiding circles in landing mode that are present in the HUD, or in a navigation mode )

 

Please if someone could explain this in the most simple way , reply here.

 

Thanks

[dragony]

1. Correct.

2. It usually describes all automatic modes, such as altitude or angle stabilization or drive-to-horizon (don't know exact English term for this).

3. Route autopilot.

 

Of course, it's AFAIK :)

[Esac_mirmidon]

Thanks a lot dragony.

 

Then this is the on route autopilot mode. Not a manual mode of any kind.?

If you don 't mind me asking.

РУЧНОМ= is it pronouns "Ruchnom"? Does it mean "manual"?

УПРАВЛЕНИИ= "Upravlenii"? Control?

УПРАВЛЕНИЯ= "Upravleniya"? Is this the same as control or direction?

I hope this is not OT, I just would like to know what the labels in the cockpits mean. I try learning Cyrillic but it was to complicated for me to learn from books and the web. As you all should know by now from my posts, I not that smart :D

1.Yes

2.Yes

3.Yes, the same as control. It's the same as second but written in genitive.

[mvsgas]

Thank you, sorry for dumb question. The Cyrillic language is very interesting, I need to learn one day.

Another one.

 

I had found in several places of the Su-27 SK manual this expression:

 

под ракурсом 0/4 - 2/4. Sometimes 1/4, 2/4 etc.

 

I imagine that this is a russian expression for the target relative angle aspect but my question is. What is the equivalence of 0/4-1/4-2/4-3/4-4/4 in western?

 

0/4 is Head on of both incoming fighters and 4/4 the tail of my target in rear aspect ? Or the inverse ?

[Esac_mirmidon]

Bump ...

 

An another question ( i am triyng to stablish the Official Questions and Answers Founding for paying your services XDD)

 

What is the meaning of this

 

неполном приборном обеспечении (НПО)

 

Could be Inertial Navigation Guide of the SARH missiles or Semiactive Guiding ?

 

The context is the part of the manual in description of the radar modes ППС ЭПС АВТ

 

Thanks in advance.

[DarkWanderer]

"НПО" usually means "научно-производственное объединение", "research-and-production union".

 

"при неполном приборном обеспечении" means with lack of instrumantal support.

[Esac_mirmidon]

9. Переключатель ППС-АВТ-ЗПС с положениями:

− ППС – задается режим высокой частоты повторения (ВЧП) зондирующих импульсов и признак передней полусферы в ракету при неполном приборном обеспечении (НПО);

− ЗПС – задает режим средней частоты повторения (СЧП) зондирующих импульсов и признак задней полусферы в ракету при НПО;

− АВТ – частота повторения зондирующих импульсов устанавливается автоматически с чередованием ВЧП и СЧП. Используется при отсутствии информации о полусфере и цели.

 

" PPS: High repetition frecuency mode assigned to the emission pulse and for the forward hemisphere mode for the missiles in ??????? НПО "

 

This is the complete text. The problem is that i do not recognize the expression " lack of instrumental support " about missiles, " в ракету при неполном приборном обеспечении " in the english " technical" version.

 

The nearest thing is semi active or maybe inertial.

The problem is that i do not recognize the expression " lack of instrumental support " about missiles

That means a missile launch with radar/EOS failure, when it has to rely only on own seeker.

The guidance system of a missile uses a bit different algorythms when shooting head on (in front hemisphere = "ППС") or "in-chase" (in aft hemisphere = "ЗПС"). Also it affects some parameters of heat-seekers.

More precisely: "НПО"="incomplete instrumental support".

[Esac_mirmidon]

YESSS ¡¡¡

 

Now i understand, or i think XD.

 

This mode is only for IR misiles? The φ0 mode i think is when you use the IR seeker of the R-27T or R-73 to lock on the target when the OLS or teh RLPK fails. But not for the R-27R family.

 

It is very interesting to know that also in φ0 some parameters are affected in IR missiles about different hemisphere, but you can affirm that SARH missiles also could be launched in HПO mode? How could this be if the RLPK are offline? Because the manual talks very clear about RLPK mode of HПO and ОЭПС mode.

 

Thanks a lot for your kind help.

ППС-ЗПС-АВТ are the radar scanning modes

ППС - Передняя ПолуСфера ( Front HemiSphere ), i'll say FHS in english

ЗПС - Задняя ПолуСфера ( Rear HemiSphere ), RHS

АВТ- АВТоматический (AUTomatic), AUT

 

 

let's I try to translate

FHS-RHS-AUT switcher with modes:

 

FHS assigns high scanning impulses repeat frequency (высокая частота повоторения in russian, also ВЧП) radar mode and a front hemisphere sign into the missile's guidance eqipment with lack of instrumantal support

 

 

RHS assigns a medium scanning impulses repeat frequency mode (also СЧП) and a rear hemisphere sign into the missile's guidance equipment w/ lack of instrum.support

 

 

AUT assigns a scan mode with automatical cycling of high and med impulse repeat frequency. Recommended to use if there's no information about hemisphere and target.

[Esac_mirmidon]

Thanks both of you, now is very clear.

 

SARH missiles could be launched in НПО? How?

[ViPer_svrd]

Please discrypt SARH...

Semi Active Radar H....... i don't know what could H to mean

[DarkWanderer]

ViPer_svrd:

Semi Active Radar H....... i don't know what could H to mean

Homing.

FHS-RHS-AUT switcher with modes:

Thanks, your translation is more precise.

 

Esac_mirmidon:

But not for the R-27R family.

To make it crystal clear:

This switch is used in 2 cases:

1.In BVR to manually override radar mode. For example, when you know from GCI that you're head on with a group of enemies - switching to corresponding pulse repeating frequency raises detection range by 10-25%

2.With "IIS" (as described above). AFAIK, this term means (as you said) RLPK failure, so the only way to use missiles (heat seekers and ARH) is to use Phi-0 mode. So, the second part of definition of two first switch positions refers to this case. SARH missiles - obviosly, can't be launched.

 

And one more thing: "НПО" is not a mode. It's just a designation of a set of conditions (just like "СМУ" - hazardous weather conditions).

 

Thanks a lot for your kind help.

You're welcome. A bit of language practice never hurts :)

[ViPer_svrd]

offcoz U know that SARH msl hasn't its own scanning equipment and needs an external radio-emission source, e.g. the holder-plane radar for the guidance, so, maybe( just maaaaayybe) it could to be launched in a HomeonJam-like mode heading on the external emission source- plane with active ECM or radar. But..... not on the typical Su-27, not with the standard R-27 family missiles and not in Lock On)))))

[Esac_mirmidon]

Well, the manual is for the Su-27CK, only a export variant of the basic all known for all SU-27 ( more takeoff weight, different and stronger landing gears and minor changes).

 

This HOJ mode could be the answer.

 

 

Now is "crystal clear " XD.

 

But is very strange ( russian way to write manuals XDDDD) mixing in the same line the operational modes of the RLPK ( better, the different pulse for different hemisphere targets) with a launching condition used only by IR missiles ( the Su-27CK cant use ARH i think. or maybe this is my mistake and this is the reason to mix both terms).

 

Also, abusing of your kind, any word about "под ракурсом 0/4 - 2/4."

 

Head on is 0/4 , 90º right side 1/4, Rear aspect 2/4, 90º left side 3/4? And 4/4?

 

Russian language is so so so extrange in sintaxis. XDD

 

Sorry for stole this russian section into an english topic.

под ракурсом 0/4 - 2/4.

Maybe Dark Wanderer can correct translate this phrase without extended text, I need more text including this phrase and maybe I'll translate it into the understandable form.

 

it means something like "with an aspect 0/4-2/4", I hope Dark Wanderer could say to you what does "0/4-2/4" mean, he knows more about the euipment and technical symantics....

Sorry for stole this russian section into an english topic.

Posting your topic in russian section is a quick and right way to get the answer + a good language practise for me and another Ru LO community people. We never get worried in this situations, you're always welcome to ask any question about the russian eqipment, manuals etc and we're glad to answer you.

 

PS There is a free online Ru-Eng translation service, it's not so brilliant, it don't know specific aviation words but it could very useful to understand the main grammar.

I use a mix of sources for the tripple translation ( From russian to english and then to spanish )

 

First Babelfish, a second pass in the google translation service and the other is this dictionary http://www.diccionario.ru/cgi-bin/dic.cgi?l=ru&page=main&forum=&cid=

 

This is the whole 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."

 

You can read my previous works with the Mig-29A flight manual and combat manual in our web http://www.cruzdesanandres.com under the section " Biblioteca " . Sorry is in spanish XDDDD

 

Thanks for a new source of help in my work.¡¡

[dragony]

Some time ago in the Russian section of forum were posted scheme, describing all perspectives from 0/4 to 4/4.

Unfortunately, I can't find it now :(

[DarkWanderer]

Ракурсом называется отношение видимой длины фюзеляжа самолета (вертолета) к его действительной длине.

The aspect is relation between visible length of the hull and real one and is determined by eye.

http://www.23ag.ru/html/rakursy.html

 

In short: aspect x/4~=x*22.5deg. from lengthwise axis; always the smalles angle is taken (left/right and front/back are not distinguished).

[Esac_mirmidon]

GREAT ¡¡¡¡ DarkWanderer.

 

This graphic is very......."graphic" XD.

 

I hope to be able to translate another 80 pages before asking again ¡¡¡
