Ah! I thought our debate was over but u r back recharged.
All I know is that the structure of your sentences makes them a pain to read. They tend to be too long, you use slang ("ur" etc.), you don't structure your posts properly to make them easier to read (too many walls of text) and so on.
'ur' is short-hand, not slang. Using shorthands on mobile is very common. U don't know diff. b/w slang & shorthand then ur English education is questionable. I told u i type on mobile & save the draft, no access to internet in office or personal laptop. On the contrary u use -ve words, slangs & personal defamation words.
I use diagrams & pictures & short paragraphs, i don't have to structure it more to submit thesis for validation. I don't read & reply to everyone, so u can also opt to not reply to me. But if u will start replying with 10+ pages of text like this then u can't accuse me. And an urban "Indian" citizen manages at least 3 languages + 1 or 2 more if going to other state for education/job. So U don't know what pain is about managing multiple labguages.
I never claimed that it masks the entire plume. Just that it masks the hottest part of the plume. Learn the difference.
So the statement is incorrect bcoz the hottest part of plume is radially inwards towards center. Ur own CFD diagrams depict that. So ur own replies are self-conflicting.
It is cheap and simple, but not that common - not in the US designs at least, I think some Russian aircraft do use it (MiG-23, e.g.).
Some jets leave the gap more open, some leave less gap, some converge & join the outer & inner panels perhaps to save # of actuators required.
I support them because they are good designs, and a far better value for money than literally anything else in the world. In 1940s I would have supported P-51, in 1970s I would have supported F-16.
So i never negated Rafale's capabilities otherwise we wouldn't have selected it. But like i said, procuring a product depends on various tech & exonomical, geopolitical parameters. But vouching too much for older gen jet against newer gen jet is also unfair as newer gen is supposed to be as much better as possible than legacy jets. It is natural evolution of technology. we are not in era of 1st/2nd/3rd gen jets.
Caution: don't go in circles & loops of comments already discussed.
Canards + levcons + TVC + good engine =/= ability to ignore basic physics.
Size is absolutely a disadvantage in dogfight. Larger size means aircraft is easier to keep track of visually, and is more likely to get hit in the first place (even though it is more likely to survive getting hit). Greater mass means increased moment of inertia, and larger wing span means increased rotational inertia, and both of these reduce transients.
This is not to say that a larger aircraft cannot be more agile than a smaller one, but to say that greater size is not a disadvantage is simply wrong.
F-22, Su-57, Su-35 & their creators ignore basic physics?
U r still stuck in WW era of visual tracking when half of world has moved to sensor-fusion, TVC & LOAL?
What r u going to do in cloudy & night conditions with visual eyeballing?
EU itself is moving to bigger Tempest & FCAS. And a hooked V-turn with TVC & pilot skill will kill an opponent making C-turn most of the times.
Linear & rotational inertia also depends on a body's mass distribution. Most mass of jet is towards center. A fully loaded jet with missiles, bombs, wingtip jammer, etc will definitely be less agile until its loads are fired. And apart from stealth looking at all the constraints of inertia only the 5th gen decided to move some weapons from wings outwards to IWB inwards & introduced TVC with stronger engine to supplement the control surfaces.
And yet you still make basic mistakes.
How can pictures & videos be mistake which are works of R&D of aero-professionals & assets of air forces?
Please feel free to point out exact mistakes. I already said i'm not aero-professional. I can't claim anyhing like u always accuse me, i merely convey what i find.
And you still cannot or do not want to understand the reason why I was using throttle ratios and other ratios.
When measuring performance...
- total weight matters somewhat, but tells you little if you do not know wing loading and thrust to weight ratio
- total thrust does not matter at all
- total wing area matters very little or not at all
What matters are ratios:
- thrust to drag ratio
- thrust to weight ratio (thrust loading)
- lift to drag ratio (incl. span loading)
- lift to weight ratio (wing loading + Cl)
When it comes to IR signature as well, an aircraft that uses more powerful and hotter engine can still have lower IR signature if it can fly at higher speeds for the same engine setting. So while total thrust and engine temperature may matter for IR signature, ratios still have a significant influence (e.g. bypass ratio, thrust-to-weight ratio and thrust-to-drag ratio).
Throttle RATIO????????
What's this? Something new u just invented?
I showed u the T/W ratio calculations which was expected from u 1st. U r deviating focus from throttle % to ratios.
How will higher speed decrease IRS? And what modification do u propose to improve speed of the same engine with same engine throttle % setting?
Because you constantly claim that I said things I never did. In other words, you tend to either misunderstand what I wrote, or else outright lie. I only hope it is the former.
Again claim accusation?
U worked earlier in insurance claim department or what?
U don't know/understand even after telling u in the line & u wanna debate? With tech progress the Digital Signal & Image processing by S/w have improved. Some H/w functions have been offloaded to S/w.
Caution: don't go in circles & loops of comments already discussed.
I am aware. But Rafale's DDM technically does have spherical coverage except for the area that is covered by the airframe. F-35's EO DAS "only" has 360 degree coverage:
See, sharing this kind of misleading & inaccurate diagam proves that U can't rectify basic things & accuse me of not understanding basic things.
So many times i mentioned that F-22. F035, Su-57, Su-35, J-20 use 6-axis positions for DAS - X-X', Y-Y', Z-Z' which gives the spherical coverage without any blindspot except rudders.
And like i said, all Rafale needs to do is have a 3rd DDM on chin to erase the blindspot in lower sector.
Caution: don't go in circles & loops of comments already discussed.
Technical knowledge is completely useless if you do not understand tactical application. And considering how frequently you misunderstand basic concepts and basics of aircraft design, I'd say that your ability to apply whatever technical knowledge you may have to the topic in question is a big fat zero.
E.g. what you said about focal plane array... EO DAS does use focal plane array, but so does literally every other IR MAWS in existence.
F-22 doesn't even have IRST, and IR MAWS usually uses short-wave or mid-wave sensors, which are good for missile warning and ground attack, but not at detecting aircraft at long distances, which is necessary for air-to-air combat.
F-22 is expensive in large part due to its protracted development, stealth skin and small numbers ordered relative to the cost. Oh, and the fact that its production was intentionally distributed in an inefficient manner just to secure political points. Same goes for the F-35.
Also, try and understand context, please? F-35's DAS may have "zoom" but that is digital zoom. It will never be as good as a dedicated IRST which has an actual, physical zoom. Also, tracked + IDed + locked BM plume at 1300 km... yeah, not exactly impressive. You do understand what ballistic missiles are? PIRATE IRST can easily detect Venus on the sky, Rafale's OSF should be capable of the same, yet you don't see me claiming that PIRATE or OSF are somehow extraordinarily better than all other IRST in existence. Because doing that is nothing extraordinary. You are falling for LM's marketing speak, when in reality saying that "IRST can detect BM plume at 1300 km" is not that much better of a boast than saying that "F-35 can fly". Important ability to have, for sure... but do you really want to use it for bragging?
If it takes a few seconds to lock a target, then it takes a few seconds to lock a target. It has nothing to do with sensor fusion, except to show that DDM likely cannot provide firing solution, otherwise Rafale would have maintained the solution throughout.
And yes, I am aware F-35 is theoretically capable of providing a continuous target tracking and lock through 360 degrees. You are yet to show any proof that F-22 is capable of the same.
Also, if you are admitting something is a secret and that you do not know it, stop claiming it as a fact. Doing so is dishonest to say the least.
I will stop "abusing you with character defaming words" once you prove you are capable of honest discussion and thus deserving of respect I normally do provide to people I have discussion with. The ball is in your court, pal.
OMG, how despearte & impulsive U r. What to expect from non-tech qualified media industry people? U r 1 of those who will walk into every qualified person's office & challenge them. Let's exchange jobs. U come & join my MNC & do my engineer's job & i'll do the media job.
U don't understand the diff. b/w the current Russian OLS which rotate & sweep & the DAS which are fixed on 6-axis points? The assembly of the OLS use a horizontal mechanical oscillating rotator, special vertically oscillating mirror & lens combo, not used in AN/AAQ-37 DAS but AN/AAQ-40 EOTS can do it if required.
After repeated examples of Digital Image Processing in phone cam, CCTV, Tesla car cam also you can't understand that IRST & MAWS functions have become highly S/w oriented + sensor fused. I also mentioned that F-22's AN/AAR-56 is a precusrsor obviously to F-35's AN/AAQ-37 which can track up to 1,300Kms but F-22 may have half or less of that which is also longer distance than Russian & EU counterparts. You think F-22 is costliest just for namesake?
"Quality comes with a price" especially with a gen leap, even the MLUs cost a lot. 6th gen is going to be costlier than 5th gen. But so far 5 gens of jets r not enough to make u understand that.
But I also said that Western industries & economies are highly privatised & capitalised which adds to cost bullying & political turbulance. A private firm engineer demands much more salary & perks than a govt. engineer. Caution: don't go in circles & loops of comments already discussed.
Dedicated physical zoom is useful in STT or Single Target Tracking & laser designator. But coming across a single enemy is rare. Jets always attack & patrol in groups or pairs spread out. With time as our mobile phones & TV screen resolution & MP cameras have increased, similarly for military optics also but not that much due to limitations of wavelengths. Obviously the engineers compared the result of higher resolution digital zoom & dedicated lens-mirrors-optics & then only implemented.
There is a huge practical diff. b/w capability & implementation, b/w CAN do it & IS DOING it. The SR-71 in 1960s had Star-Tracker navigation. So if EF-2000, Rafale optics can detect Venus but not inform the pilot of surrounding jets & provide a firing solution then better use them for astronomy, not military survival. However like i said a S/w MLU can improve it with increased cost of jet which every customer may not pay, like Croatia perhaps. You guys don't even have the extra customizations which we have nor a considerable military & IT industry of your own.
Like i said earlier neither i'm USA fan nor I'm in favor of full military privatisation & capitalism hence i don't fall prey to marketing gimicks. My technical IT qualification & experience (which u consider big fat zero) gives me capability to technically examine, rectify some aspects to certain level. Hence there is nothing to brag or take blind favor of LM, USA. Caution: don't go in circles & loops of comments already discussed.
Again & again u r asking proof of costliest privately developed American jet's classified details from"Indian" citizen.
Go email & challenge USA, Pentagon, USAF, LM. But being a non-tech graduated Croatian with no defence & IT industry u r comparing imported French jet just bcoz ur country bought it
Also there are some technical things which r secret like the S/w code of OS (Windows, IOS, etc) of our laptop/desktop/tab, doesn't negate facts of their capabilities. Only Linux is open source & has flavors but does that mean MS Windows & Apple IOS are incapable or questionable just bcoz they r not open?
So all the S/w engineers working at Apple & MicroSoft are dishonest???
You don't even know how to communicate & discuss with any type of engineer. We have to study daily & on weekends also, what the hell u media guys do except baseless bashing & abusing on TV & internet? U just proved urself to be highly cheap & uncultured person by justifying ur continuance of using abusive language u might hav picked up from movies or ur upbringing. Either u r just another typical 20s guy or genuinely immatured & uncultured.
There are overlaps between generations, yes, but my point is that even being of higher generation does not always mean a jet is superior.
And neither i said of absolute superiority of a newer gen jet otherwise i wouldn't give huge 40% win chance to any legacy jet. Caution: don't go in circles & loops of comments already discussed.
There is nothing to stop Rafale from doing so during combat except for FCS limit, but why would it do so? In air combat, if you lose too much energy, you die, post-stall maneuvers bleed a lot of energy for a very questionable benefit.
Caution: don't go in circles & loops of comments already discussed.
U will loose energy & altitude due to poor engine. POST-Stall is for such jets only but a TVC jet has to be designed with good engine, avionics so that going into post-stall is choice of pilot, not compulsion. The F-22 videos showed it gained altitude after V-turn.
Fishhook turn can be done by F-16, which has lower AoA limit and less nose authority than either F-22 or Rafale:
https://man.fas.org/dod-101/sys/ac/docs/16v5.pdf
So yeah...
Literally everything you have claimed about thrust vectoring is wrong.
U wanna credit a diagram without scale showing a C/U-turn labeled as fish-hook turn over multiple videos showing V-turn? Good, luck!
But if F-16 MATV was implemented then surely it could do it.
I am qualified when I can clearly see that your conclusions are completely wrong. I have shown you why, multiple times, with actual scientific documents, yet you keep beating the same old drum.
I can clearly see u will walk into office of all qualified bankers, engineers, doctors, lawyers, etc & tell them that u r more qualified than them. Perhaps u r doctor+engineer+soldier+lawyer+banker+everything, all in 1
I never crossed against the docs u showed for CCC but that's it. The examples of TVC & TVC+canards are in front of whole world. Those who have the technical capability & economic & geopolitical feseability will implement such technologies no matter how much u cry. May be it is not feasible for countries like Croatia who don't have proper defence & IT industry & have luxury of NATO.
Omni role =/= long-range strike aircraft. It merely means ability to carry out multiple missions concurrently. Or are you claiming that F-16C is designed to deliver nuclear missiles to Moscow?
But apparently, troll faces are more important than logic in whatever reality you live in.
So now u wanna go against Dasault itself now? Did Dasault define omni-role=long range? Why should i claim F-16C is designed to deliver nukes to Moscow when i mentioned it to be among worst examples in today's era?
This is why troll smileys are important
OK. Learn what "post-stall" is, then we can resume discussion.
Because when you think that bloody TVC "allows engaging in low speed without entering post-stall"...
Nevermind... I'll try to educate you, but this is why I keep repeating that you should read actual literature instead of whatever marketing BS you had kept swallowing.
Stall is separation of air flow from the wing.
Post-stall maneuvers mean that aircraft is capable of executing maneuvers in conditions of stall.
Thrust vectoring allows aircraft to execute maneuvers even in conditions of air flow separation.
Thrust vectoring maneuvers are the definition of post-stall maneuvers, yet you claim that TVC "allows pilots to engage in low speed without entering stall"... if you want to engage in low speed without entering stall, you don't use TVC, unless you have to because your control surface authority had been reduced for some reason. But the usual reason for loss of control surface authority is... wait for it...
stall.
Go get a B.E. + B.Ed. degree 1st if u wanna educate others bcoz there r lots of unqualified people like u
eager to teach qualified professionals
just after referring to some docs, terms & definitions on internet rather than 8 semesters of books.
"air flow separation" is all just u know without considering the practical result of it which is loss of lift. That's where a strong engine + good FCS avionics helps a jet to still push up & go where the pilot desires rather than tip over. That's how rockets also work at igh altitudes & space. F-22, Su-57, Su-35, Su-30MKI will not wait for loss of control surface authority after merge. TVC was approved by govt. & air-forces of USAF, IAF & RuAF to proactively take advantage of it, not wait like a traditional legacy jet. U think professionals of all these countries & air-forces are fools to have TVC?
Except it isn't available. TV shows provide, at best, half-truths, snippets of quotes and sound bites. It cannot replace proper study.
Or do you really think that one can learn French history by reading Asterix, or US history by watching Star Wars? Because that is what you are claiming here.
But the fact that you think actual research and design documents are "boring black & white stuff" does show how seriously you are taking this... which is to say, not seriously at all. And then you try and lecture me.
Evidently u don't watch anything. U might wanna BAN the entire TV industry who interview & showcase the actual scientists & engineers & their facilities. Giving names of at least 5 of them was not enough for u, then go try to arrange liv F2F interview with them.
Asterix is comics & Star Wars is movie. U wanna compare children's comics & movies to scientific documentaries showing real scientists, engineers, pilots, facilities?
I already said i'm nobody to "lecture" u bcoz u n me r not qualified as aero-professionals.
Single-piece canopy is not necessarily a good idea. Yes, it does provide better visibility, but it is also much heavier and relatively more fragile. More importantly, if something happens and canopy falls off (has been known to happen), having a windshield a la Eurocanards or F-15 is far better and more comfortable for the pilot than the F-16 / F-22 / F-35 setup which leaves the pilot in the wind... literally.
Flexible poly-carbonate, etc have been researched which can easily withstand bird-strikes. Fixed front is stronger but increases RCS & canopy falling off would be poor maintenance or design & a rare occurance.
F-35 canopy is broader hence it has included the frame-arc inside behind the RAM treated glass.
