The problem here shouldn’t be about “cloning” or not since it’s obviously not for the eventual J-10. The issue is whether considerable influence from Lavi’s design was used for the J-10. I would say the Lavi influenced the J-10 project before the almost total aerodynamic redesign (except for the canard-delta arrangement). Early hand-held models of the J-10s did look very similar to the Lavi’s design…especially the swept back trailing edge and the less pronounced leading edge sweep. However…that design was totally changed compared to today’s finalized J-10. The problem i believe is two-folds. First, China is still not as good as manufacturing/design dense/blended airframes as the Russian and Western counterparts.
That does not explain how they can mass manufacture J-11s with considerably better precision and finish than the original Su-27s.
It also certainly does not explain why the J-10’s wing is actually more blended than the Lavi’s at the wing root corners, nor does it explain why the J-10’s fuselage has a more complex curving geometry than the Lavi’s. In fact the J-10 looks more curvaceous than any of the Eurocanards.
They can machine the parts, but integration is the problem. Look at all the indigenous fighter designs and that can be seen clearly. Things are still put together as segments rather than designed as a whole. Even the J-10’s wing/body section used fillets instead of blends. This may be internal and cultural inertia at work…simply if it looks good enough to them where’s the problem? (Similar to the familiar lines of Russian aircraft with multiple buldges and surface roughness….what seems to the be the problem? No problem except aethetics? Maybe). Second, the overly optimistic expectation of the indigenous engine and the final adoption of the Russian engines means the stability of the aircraft becomes a problem against the original J-10’s much more compact design. The aerodynamic center must be shifted back (taking away that swept back trailing edge) and the forward section elongated. This can also reflect the required engine duct length due to the Russian engine (as compared to the assumed Chinese engine that still is not available for the J-10). On a side note, notice the intake for the J-10 is not that much different from simply rotating the intakes that the Chinese got used to (J-8II’s).
The Chinese engine, WS-10 was first tested on the J-10 on the first five to ten prototypes, switching to the AL-31FN when the latter showed superior performance and shorter spooling times. You can visually see that the rear ends of J-10 prototypes are quite different—the diameter of the Russian engine is actually slightly smaller, allowing the fuselage shell to be extended all the way near the nozzle in order to blend and maintain the original lines of the aircraft. A more powerful version of the WS-10, the WS-10A is the one now powering J-11Bs today and is being tested now on J-10s, forcing Salyut to sweeten their offers by increasing the power of their own engines and offering co assembly agreements.
This fact shows that the intake duct was designed for the Chinese engines already in mind. The early hand held models show a Mirage 2000 sliding inlet intake turned bottom, which is an indication that the plane from the beginning had a variable intake right from the start. The J-9 designs also had variable intakes.
Overall the design of the J-10 shows the Lavi’s own design had some issues with it too, meaning that the J-10’s design could have also corrected these issues. The Lavi’s close coupled canard may be a bit close to the main wing, allowing turbulence to fall over the main wing, and the tail rudder, a splitting copy of the F-16’s, may not be adequate, as all finished delta canards, including the Euro ones, have larger tail rudders.
The long curving back of the J-10 may reflect additional fuel storage space, same technique used in the Su-27 and MiG-29C, while the large blending and web flaring of the wing roots which is actually more apparent than the flawed line drawings shown here, suggests large fuel bladders. All these are meant to greatly expand internal fuel capacity.
The increases in engine power, plane size and fuel capacity all suggest that the original design of the Lavi, inspiration or not, would never have met PLAAF’s original intentions and specifications, as they are trending clearly towards larger and heavier fighters.
There is here the most important aspect of your fantasies, you think the Rafael engineers did not think about self attrition and of course the PL-9 is a smart missile that won`t kill J-10s.
The Helmet Mounted Sight (HMS) is the first thing that indicates to the missile where to direct its head seeker, since the Python seeker has a wider range of view it can scan and survey 220 degrees, or +110 and – 110, however if it wants to go beyond that it needs a databus system that indicates the target position with respect the Python carrier, full LOAL capability is only available to aircraft with a MIL-STD 1553B databus to transfer IMU alignment to the missile, using cues from the aircraft radar, a helmet-mounted sight, or off-board targeting data, the Python 5 can thus undertake engagements in a 360º radius around the launch aircraft. The IMU is also sensitive enough to adjust to the wing-twist effect suffered by the wingtip launchers on the F-16 and to align the missile for an optimum angle of attack on launch, in that the HMS still is used as several other sensors include off board ones , so it is not only one system but several.
The AIM-132 is the same in the Panavia Tornado that databus is absent so the Panavia Tornado of the RAF only can engage targets in a 180 degrees engagement angle .
This is not the same in the RAF Typhoon or in the Australian F-18s which can engage rear aproaching targetsThe Russians also use the RWR to direct rear firing R-72 missiles as well rear looking radars.
To be honest you really don’t know what the f*k you are talking about. RWRs only tell you a hostile warning in the plane’s rear hemisphere. However, it does not distinguish targets per se. If a friendly and a hostile is within the same hemisphere, good luck.
But the MiG-29 and F-16 have LERXes that give extra lift ahead of the center of lift and stability is a factor of the relative position of the Center of lift with the center of gravity, the delta wing has nothing to do with that and still will stall faster that other types of wings such as those of the Su-27.
Also the canard generates drag ahead of the main delta wing.
Prove that stall statement by the way.
The Rafale, Eurofighter, J-10 and the Gripen have good instantaneous turn rates but they loose energy fast and their sustained turn rates are barely as good as the F-16 or MiG-29`s or worse as in the case of the Gripen and probably the J-10
We have already shown the latter is not true. Go ahead, prove it.
What a load of crap. Do you go around with a PC logo that says “Idiot Inside”?
Recommendation? and ur not going to fight over the top of airbase.
and Flanker can turn on afterburner to go into high speed and altitude into the fight. once u lose fuel tanks u cannot get back them. Flanker can turn off the afterburner
What a load of BS. I have never heard of anyone in any airborne tactical exercise trying to deliberately lose fuel by using his afterburners.
so these are test round missiles?
Yes.
it wont make a difference when u have external load out and fuel tanks. and Airforce which can afford Flanke can also afford decent Ground radar. ur non-stealth J-10 cannot hide.
What a load of bull. Anyone with a J-10 can also afford any ground radar. That ground radar can also be jammed or destroyed by SEAD.
but R-27 have bigger motor and more fuel and being heavier will go considerable distance.
Not the R-27R, only the ER, but the ER’s distance is not proportional to its weight. Inefficient. Even at the edge of its range, the R-27 would be flying so slow and low in energy that it is practically useless, compared to a more aerodynamic missile.
I didnot say most of fuel. 10 to 15% is normal during take off and gaining intial height.
LOL. The Flanker needs to be about 50 to 60% of its internal fuel to be at the minimum of its proper thrust to weight. Sukhoi recommends 56%. Tell me how you can attain that by losing 10% of your fuel from take off, huh?
i am comparing two fighters with external weopons and one have external fuel tanks.
And the J-10 can dump its external tanks in a jiffy. Instantly. You cannot do the same on a Flanker.
smoke coming out from those obsolete PL-8 missiles.
Bull. Smoke is only used for the test demonstration of the missiles in order to create both a spectacle or to make it easier to track for flight tests purposes.
neigther do J-10 is stealth fighter.
The J-10’s intake has baffles deliberately designed to prevent radar reflection coming in. The S shaped internal duct prevents this further. The Typhoon and the F-16 does this too. The MiG-21 does not have this, nor the Flanker except for the Su-35 and the J-11B that have newly redesigned counter radar reflective baffles.
how u can say definitely?
I can say definitely because it is true. The trapezoidal wings on the R-27 is draggy with protruding wing spans and do not sweep backward enough. The R-77, as well as other AAMs like the AMRAAM, are on the right path not to have large draggy fins at the forward section of the missile.
for those who say the Kfir is a complete clone of the Mirage III
Here all this idiot goes on to show is how the Kfir line by line is exactly similar to the Mirage V. Try to do the same thing on the Lavi and the J-10 you will not get the same thing both top and bottom.
Where is your problem about IFF related to that?
In this case you are the one to display ignorance to distract from a lack of capability. You do still speak of an IR-AAM, but such seeker-heads are no longer state of the art by the way.
Excuse me huh? I relate about trying to IFF something on the back when your IFF equipment is facing the front.
energy is mass into velocity. read about MIG-31 vs Su-27. and Su-27 consumes most of fuel during takeoff stage. In actual combat it will be no more than 6 to 7 tons. which will give Su-27 greater than 1 TWR.
No fighter or any plane consumes most of its fuel because of takeoff.
it is very minor when ur carry external weopons and fuel tanks and u have
When you carry external weapons your RCS increases, that’s why the F-22 and F-35 uses internal bays. So does F-117 and B-2.
seen the amount of smoke generated in J-10 promot video from missile firing. and it was wvr missile.
LOL there is no video of any J-10 smoking ever. The AL-31F is a smokeless engine.
radar paint was used on MIG-21Bison during 90s. it is not a factor.
Radar paint does not make a Bison a stealth fighter.
R-27 is heavier missile and it is most likey having greater speed and range than R-77/PL-12 class missile just like semi-active AA-9 Amos.
The R-27R definitely does not have greater range and speed. The R-27ER does but its not proportional to its weight. Unfortunately the R-27 has a draggy fin design and poor aerodynamics.
here are some answers for you
By definition, the Python 5 is considered to be a short range air-to-air missile, yet its range exceeds regular air-to-air missiles, and is more close to what is technically called BVR (beyond visual range) missiles.
Those are not answers to the IFF question, Flogger. Once again, you display your sheer ignorance on the real issues.
All you post is a bunch of marketing ad work, not withstanding its range is exceeded by the rather common R-73 and matched by the PL-9C. LOAL abilities are also there with the AIM-9X and IRIS-T. LOAL for an IR AAM is not hard to do, as IR LOAL is also seen in some AshMs with IR seekers. Anyone can put an inertial guidance unit into the missile, what’s so hard about that?
As for your other questions, there is no such thing as “beat” if you cannot stop one fighter before it can launch its missiles. So the Python V maybe more agile than the PL-8B, but its not really missile vs. missile that happens but missile vs. plane. So the PL-8B is less agile as a missile, but the late model F-16C it’s chasing is less agile than the J-10. The F-18E ain’t exactly a fighter you want to use to run away from missiles either. The result of most engagements, there is simply going to be a high chance of mutual destruction simply because you can’t stop the other guy from shooting his, and destroying his plane isn’t going to stop his missiles doing revenge on you.
If there is one thing I don’t really like about the PYthon 4/5 series, is the airframe are high drag (meant more for control authority), so the performance penalties it will impose on the plane maybe greater than let’s say, AIM-9L.
PLA daily would tell you different. Actually, most account of J-10 vs flankers say that flankers simply can’t shake off J-10. And besides, why do you need to carry 6 BVR missiles when 2 is enough to shoot the other guy down? Radar is bigger, but the tracking range of J-10 is greater than that of MKK. TWR of flanker is not better. For J-10 with WS-10A, it’s 13.5 tonne/11 tonne.
Carrying too many BVR missiles actually put the plane into an immediate tactical disadvantage due to the drag and weight of the missiles.
Why does J-10 need Meteor or python v to beat earlier mig-29s and su-27s? Those 27sk we got can’t even fire R-77. They can’t even beat PL-12 equipped J-8F.
PLAAF later Su-27UBK and J-11s can fire R-77 (circa received and made from year 2000 and so on). Just the early Su-27SK and UBKs don’t.
J-10 is not a Stealth fighter that Flanker cannot see it from considerable distance and adjust itselft into favorable position to enter into a dog fight. Bigger fighter gives more energy to BVR missile. 6 BVR are good in case u want to shoot down 3 light fighters. Tracking range of J-10? how much difference. barely a few kms at all. which have no effect on outcome.
Bigger fighter does not mean more energy to BVR missile. Faster fighter does. And I mean faster fighter at the moment. Heavily fuel loaded Su-27 is not a fast fighter. You need to deplete some of the fuel first.
The J-10 is not a stealth fighter but it does have some RCS reduction measures in the intake and use of radar absorbent paint. Furthermore, it does not expose the engine intakes. The Flanker is not a stealth fighter either, but it is a large RCS fighter, meaning it is that visible to radar, thanks to its engine inlets and exposed engine fan blades from the front.
Sukhoi has focused a lot in improving the RCS of the inlet design of the Su-35 and Shenyang likewise on the J-11B. Measures also include adding radar absorbent coating on the front engine intake face. Its not very sure how much is done on the Su-30 however.
Su-27 still hase R-27 that has greater speed and range than PL-12. Active BVR does not matter if ur in 1 vs 1 comparision. and there is 40KM version of R-73 with 120 degree offboresight.
You are referring to the R-27RE and R-27TE. That is extended version, not the base version, which does not have the speed and range of the PL-12. The PLAAF has both missiles and I am pretty sure that was also factored into exercises.
Man all you do is post a bunch of copyright material and think you’re smarter somehow.
Yeah yeah Crobato let us analize your fantasies
[B]The third generation PL-9 is better than the fifth generation Python V, the 70Gs hold by the Python V are not an advantage compared to the 35Gs or 40gs hold by the PL-9, the Python V and Python IV`s 180 degrees and 220 degrees field of view are not an advantage compared to the PL-9`s 120 deg.
And you have no idea that 70Gs are redundant, and you know what redundant means in the English language huh? Around 35 to 40G is enough to deal with a 9G turn.
And once again, something that Sens is not addressing, because the IFF capability is not in the missile but in the plane. You are not able to exploit the full off boresight of your missile if your IFF does not match that FOV.
Crobato you have to swallow the truth, the PL-9 is a more primitive missile, it is not better and to jamm the seeker or the data link is not easy,
Whether or not it is easy or not that is not the issue. The issue that it has been DONE.
the IFF recievers also do recieve information from several sources and in a dogfight the J-10 shape is different to an F-15 or F-16`s and what the pilot
If another plane is in the position to IFF a target, it would also be in a position to shoot it down, making the rear aspect shot redundant.
The J-10’s shape is not much different from an F-16 on the side.
of an F-16 only needs to do is turn his head, lock on with the Helmet mounted sight fire the missile and that is it, the Python V allows to its pilot more freedom in terms of cueing even without pointing the airplane nose at the intended target.
And how far can you turn the head? Want to demonstrate to us your alien ability to turn it completely around?
And once again, you don’t address the issue. You certainly have a pathetic foolish notion of geometry and don’t know what degrees are. An HMS is still limited by the limitation of the human neck, which cannot pivot backward.
And you have no idea that the PL-8/9 are also helmet cued.
Now can a J-10 win some dogfights? probably yes, will it win more often than it loses? probably not if it faces the Python V or IV.
Lol. In NATO exercises with F-16s vs. MiG-29 aggressors using the R-73 missile, the ratio wasn’t certainly overwhelming, despite the AIM-9L only having 25 degrees off bore while the R-73 has 60 degs and an HMS. Once the initial surprise was worn out, experience gained, and tactics adjusted, the favor went further to the F-16.
In PLAAF exercises, pilot that are not using HMS, limiting the boresight of their missiles and yet they still frequently gain victories over pilots that do use HMS. And this phenomenon is not local to the PLAAF as I gave you the NATO examples.
The advantage is in the side that has fifth generation missiles not in the side it has third generation missiles。
Excuse me? “Generation” does not really give a flying f*ck. When you are 60 degrees or 90 degrees, it matters much less.
To explain what is happening above, is that you seemed to have no idea that by far the most common encounter between two aircraft is the “merge”, when both are coming in at each other head on. The vast share of “kills” will happen here and having WOBS at 60 deg or 90 deg or 180 deg matters little here. Maybe you like to find out why AAMs and SAMs don’t bother with high WOBS? At these circumstances, an F-15 with Sparrows has as good a chance as hitting an F-15 with AMRAAMs. Following that, the next most common encounter is having one plane behind the other for a tail shot.
The rest is typical Flogger tactic of bringing in irrelevant material to obscure the issue. You never address the true problems of targeting sideways to the rear autonomously. Tell me where the hell can an HMS allow you to target backward of the aircraft?
The advantage of Sparrow over AMRAAM is at close range, where the target illumination from the F-15’s radar is going to be a lot stronger than the emission from the AMRAAM’s battery powered seeker. With this sheer illumination power, being “xrayed” as it is called, the Sparrow can lock on to the target faster than the AMRAAM.
More excuses Crobato to claim the J-10 is almost an equivalent, however operational experieces show that difference of 2/3 in the head seeker`s field of view can mean victory of defeat, the PL-9 barely has 120 degrees in the head seeker`s field of view the Python IV has 180 deg and the Python V has 220 deg of field of view.
Bull. There is something called diminishing returns. It may make a big difference between 30 to 60 deg, but over 60 deg, the benefits compared to the cost of implementation began to seriously diminish especially because the human head, as well the field of view of the radar’s pivot, cannot do the same turn.
The PL-9 is limted to frontal attacks always with the J-10 nose in front of the target,
Shows you how little you know of missiles. The PL-9 is an all aspect missile, which means it attacks from every direction. Previous to the AIM-9L, all IR missiles are rear aspect, which means every old missile is capable of attacking from any part of the rear quarters.
the Python V or IV carrier can always fight and down any enemy that has just over passed and failed to launch a missile before it gets a good oportunity once more and gets the J-10 with its nose pointing at the Python V or IV carrier but of course this is something that in your fantasies you can not see.
The only fantasy here is the way how you portray missiles to fight, without addressing IFF concerns or the limitations of radar and human head rotation.
Data link is not an inconvinience as you claim since the Derby has its own head seeker and modern aircraft use data link to lock on and cue targets via other sources today`s Gripen can do it.
LOL. Datalinks can be jammed, and if another aircraft has one bogie in its radar, that second aircraft would already be attacking the target in the first place, making rear aspect missiles tactically redundant.
The Derby can even be enslaved to the HMS
Wow, you’re talking as if this is a new innovation. Maybe you don’t know, or even read the old Su-27SK manual, but the R-27s—old missiles—can also be enslaved through the HMS.
You conviniently also forget the J-10 also has a radar and this can be jammed and having no data link or Lock on after launch limits it more than the F-16s with Derby or Python IV or V, in fact data link allows the fighter to swith off its own radar
More bull from you. The J-10 has a datalink, you can see the large antenna right behind the pilot. So yes, it can do what you say. As a matter of fact, even the J-7s have datalinks. Datalink technology is really old; the Soviets use them to vector fighters under ground control.
By the way the Python can hold 70Gs more Gs than what the PL-9 can hold in fact twice the Gs
Another useless feature. Once your missile can attain 30 to 40G, it can already more than enough to lead target aircraft maneuvering at 9G.
In few words crobato that difference of 60 deg or 100 deg means the J-10 either needs to point the nose at the target and maneuvre and lose speed or over pass the target and being hit by a missile lauched at it
More Flogger idiocy and technical incompentence. The ability to harness over 60 degrees of off boresight is limited by the FOV of the human head and vision, the wings blocking the view of the aircraft, the FOV of the radar, and the FOV of the IFF instruments.
If missiles are so wonderful, figure out why even today, future aircraft are being designed for maximum pointability. Even on the Red Flag exercises, it has been deduced that WOBS and HMS are not the silver bullets they claim to be, that aircraft positioning and pointability are still kings, and that ACM training still has its place.
The Phyton 5 is a LOAL missile!
Yes, it is a LOAL missile, but every missile of such do require authorization to fire which has to pass through the IFF system.
