MarcellogoT-ViP,
Soud like a new phone company. T-com and Vip already exist (Croatia for sure). Have they merged?
MarcellogoOk, with these last pages we had just assembled the greatest collection of wild assumptions in the whole world.
Still no one can say nothing sure about maximum velocity or efficacy of active radar cancellation than before, so let’s end it up and wait for the sixt prototype.
Agreed?
MarcellogoMarcellogoHang on a minute! These exchanges only started because you had claimed that active cancellation was impossible. I have responded by citing – from open sources – research work that was carried out in this field by MBDA and Thales – including a statement by a named senior official to the effect that some success had been obtained during flight trials. So I have given evidence that active cancellation is not impossible. And that was all I set out to do.
If you have difficulty in understanding how the technique works, then that is your problem, not mine, nor that of my contacts in the EW industry. My role in explaining the basics of EW to young engineers ended several decades ago.
I have no experience with commercial noise-cancelling headphones, but a military active-cancellation headset that I tried in the mid-1980s was very effective.
There is no need for the ‘processor’ and ‘generator’ shown in your diagram. The pulse train that needs to be transmitted already exists at the output of the receiver. The only manipulations required are a reversal of phase and adjustment of the amplitude.
Such is reality for many types of deception jamming involving signal manipulation. The time needed for pulse detection and manipulation will often mean that the leading part of the pulse is likely to be unjammed. The job for the EW designer is to keep that unjammed period to a minimum in order to minimise the degradation suffered by the jamming, while the task of the radar/ECCM designer is to exploit that unjammed period by using techniques such as leading-edge tracking.
NOTE FOR MODERATOR(S):
Would it be a good idea to move the discussion contained in postings 929, 936, 941, 942, 946-949, and 951-959 to the ‘ECM pod can reduce RCS?’ thread? Folks who come to this thread to discuss the PAK-FA must be getting rather tired of this digression into the world of EW.
Supporting the request. +1 for the post.
MarcellogoISIS is a de facto proxy army for NATO and its Arab allies
if not for the executions and brutal social policies (which are extremely similar to those in Saudi Arabia btw) and terrorist attacks, ISIS would be little different from the Free Syrian Army
except that it invaded Iraq, which is supposed to be a Western ally, but shortly before kicked out the US and started leaning towards Iran
so ISIS was a gift from heaven from a strategic point of view, as it not only fought Assad but also a wayward Iraqthe West didn’t bomb ISIS when it first invaded Iraq, which is very odd as it could have stopped the invasion in its tracks. later it did, without Iraq’s consent
and ISIS did everything possible to provoke Coalition bombardments. they could have just kept quiet, but instead it’s like they wanted to get bombed
ISIS gave the Coalition the excuse they needed to bomb in Syria (and Iraq), something they couldn’t do before
bombardments which seem to have had very little succes in stopping ISIS, despite having hundreds of aircraft
but which have decimated the infrastructure in those regions, and caused a flood of refugees, typical objectives when you want to destroy a country but you can’t target its military directlythen Russia comes in, which just a few dozen of often borderline obsolete aircraft and quickly breaks ISIS’s back, while at the same time hitting the Syrian rebels
Just remember how ISIS get most of its own territory by stealing them to other rebel faction, ISIS is from the beginning an Iraqi formation so they have not invaded it just they get an hold in Syria first and in Iraq later.
Same about international and russian intervention: the latter is much more efficient because is using the right tactics and the international coalition a whole compilation of political strategical and tactical errors, not for some lack of will.
MarcellogoI used to come to this thread for news of RuAF operations in Syria… Can’t the mods do something about all the bullsh!t? Thanks.
Ink, you have to pardon me.
I have given a reply to your question about russian UCAV in the RuAF thread, technicalities would find instead in the Russian UCAV in Syria one.
News about the russian raids in Syria have toned down in those few days, we know that they have suspended/ slowed down them for a pair of days to allow cessation of hostilities and now they are back but now they kept them a little out of news focus.
Discussion about Daesh is not out of contest there, as it can underline the fact that the so called “proxy “states are not the mere handyman of greater powers (hence the term cospirationism) but exactly as the name implies states having their own list of priorities, their own internal politics and their own goals.
MarcellogoAbout the SR-10 and the training of russian pilots it’s convenient to compare it to what Aermacchi. owning the western twins of Yak -130 is actually doing.
It has developed an advanced version of the Siai Marchetti 211/311 with the name of M-345 and a turboprop version of SF-260 adn shifted their respective part toward the high.
So the primary trainer would eat up a part of the former basic phase, the basic one a part of the advanced one and the LIFT would take the rest plus a consistent part of the one previously made on the OCU version operative planes.
So even if there would be three different trainer instead off MB-339 coveringboth basic and advanced training there would be huge savings until the two third of advanced program and even more in the OCU one, final numbers of flight hours to have an operative pilot would be optimized also.
So there would be definitely a place for SR-10 in such a perspective.
About the UCAV thing, it seems that the operative result of RuAF are going in the complete opposite direction both for what concern them tham generally about the real utility of a western like all PGM arsenal.
MarcellogoA direct creation is a thing of such a group would have been a masochist act, much more probable a situation in which they started some dynamics , involving the use of the wrong proxies and those backfired spectacularly, same happened with Bin Laden and even bfore him with all the wahabism spread around the worldas a countermeasure to Iranian revolution and Soviet war in Afganistan.
With proxies thing are often so, they can relieve ou by a great deal of your “white man burden” but they have their own interest and inner dynamics, happened the same in ancient times when Rome ruled, happen even more now that the main power of the world has grown weary of any direct intervention
MarcellogoEven in a moderate person like Sanem sometimes cospirationism can get an hold.
Let’s say all the US politics in the lastt forty years has a lot of the apprentice wizard situation.
MarcellogoIt’s always thew same brochure like discussion: S-400 is just a part of a very complex multilayered, extremely mobile AD Systems. Several different SAM, lots of radars in different bands, fighters and so on.
Same is with the air strike, there will not be just the F-35 but all assets of USAF or USN supporting it…and no, low RCS alone is actually a no go against update AD system, it would make things a lot easier but it would need same kind of supports of any other attack plane.
MarcellogoJust to remember that High AoA means just that plane still retain a positive lift factor when going into a steep dive. It doesn’t automatically translate in a post stall maneouvrability of any sort.
So TooCool_12f have its part of reason,Jessmo it’s own.
For the rest how would fare an old F-100 against even a baseline F-16A?
Because, you know, they have passed lessen years between the two than between F-16 operativity and F-35 FIRST FLIGHT.
Marcellogomost Jews are democrat and they make up a large number of that party. if Bernie becomes president, he’ll obviously be pro-Israel because he’s Jewish.
most republicans are christian, they want to prevent the end of the world so they feel they need to protect israel.thus both parties are pro israel.
Right the contrary my dear, being israelite he is the only one that wouldn’t be blackmailed by their actual NAZIonist government led by Bibi #Iranjeans Nethaniau.
MarcellogoOnly that there seems to be a huge hole in your assesment..
The F-22 supposedly did 1.72 Mach, under testing(I have my doubts under which criteria..)The F119 have slightly above 15.000kgf.
By my mk1 eye balls, the PakFa looks sleeker with less frontal wet area. More angle wings, airfoils(Not sure about Pakfa, but F-22 has a rather massive airfoil), smaller optimized stabz(same stabz as on SR-71!!), and an air intakes optimized for high mach..The 117 produce 15.000kgf.
And yet, the F-22 somehow massively outperform the PakFa…
,m not talking about Supercruise without AB, but drag index, induced drag, Transonic speed regime and high Mach flight, with optimized Air intakes in general.
Something is not right here, why the very conservative numbers on PakFa when even the more drag’ie Flanker can do Mach 2.35 on the very top..
I wouldn’t call Flanker, above all the baseline model draggy in any way, the blended wing/podded engine formula of Russian plane is wonderful on that regard, PAK-FA take it at a higher lvl but have to deal with internal bay issue, IMHO it cope with it in the best possible way but have to nevertheless.
For the performance gap, always remember that the T_50 is still in its developmental phase, so some report seems very conservative others just out of this world.
MarcellogoLet’s back into the ground with a big news, the updated numbers of RuAF forces in Syria.
MarcellogoLet’s consider how in the next fifteen years there will be only two important US aeronautical programs: this and the trainer one.
Given that no common engine can be used in both I would argue they would be quite limited in their choices, developing a whole new engine for the bomber only is out of question while using something like ADVENT F135 would gave a criticaal mass.
