it seems to me that F-35’s canopy is fairly large from the side view. does it contribute to a lot of RCS or is there RAM on it?
Not exactly “RAM”.
This is a very, very simplistic explanation, but the canopy is treated in such a way that it deflects radar waves (they dont cross it).
From the radar waves perspective such a canopy behaves very much in the same way that the rest of the airframe.
I’m just amazed that people keep answering….

Its kinda hard not answering!
Between the generation “Zwei”, the “tradition dating thousands of years back”, the “superior data linking”, the “sensor fusion” and more important, the “bump air intakes”, this is becoming of the funniest topics since, well… ever?!

Severall chaps here, including me, have already pointed to you that you are not exactly an expert on Chinese combat aircrafts, quite the oposite, your lack of knowledge is obvious.
Answering like you do, well, without a clue and with an awfull lot of nationalistic rubish pretty much indisposes everybody else… Thats the reason why you get, repeatedly, getting banned.
But keep on…
Thunder came years later, true, but it incorporates recent advances in aerodynamic designs and technologies that Gripen does not have. Examples include bump air intakes, MAWS, more advanced EW active cancellation, better weaponry etc.
LLLOOOOOOOOOOOOOOOLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLL
Beautiful, absolutely beautiful, this topic is going to the classics. Some moderator could make this a “sticky”?
“bump air intakes”
😀
The “more advanced”, highly “bump” topic…
As of tomorrow, however, with P1E, the gap will be narrowed.
Maybe, but Dassault, Thales and the French MOD have not exactly “frozen” the development path of the RAFALE.
With the Indian victory, they may even have to accelarate the program (think MBDA Meteor, IOC from 2018 to 2015/16, by example).
And P1E doesnt bring an AESA and CFT´s, the kind of improvements who would level the operational capability gap.
Or in other words, the latest production versions. In fact the AESA F3 Rafale was even more superior in comparison.
Again no, Dassault (praise to them) sent an AESA equiped aircraft to the Swiss evaluation which was extensively flown and tested.
Engine blades contribute to at least 30% of frontal RCS. Thunder’s bumps hide the blades completely. No way Gripen’s frontal RCS can match Thunder’s IMO.
F-15SE’s tails are canted 15 degrees, which isn’t much. Canted surfaces don’t reduce RCS as much as zig zag surfaces, and don’t contribute to RCS reduction from the front but only from the side. Thunder Block 2 is assumed to incorporate some RAM like the ones found on J-10B. Pylons increase drag, but don’t increase frontal RCS as much due to their frontal surface areas being very small compared to conformal weapons bays which have much larger frontal surface areas. I estimate Thunder Block 1’s frontal RCS at about a quarter to a half of F-15SE’s frontal RCS and about a half to three quarters of Gripen C’s frontal RCS. 😎
Silly claims.
Undoutebly there a handfull of chaps around the planet who can make educated guesses about the RCS of an aircraft by looking at them, but you are not one of them…
Still the Swiss came to the conclusion, that even an up-graded Typhoon could not close the capability gap to the Rafale. :dev2:
Exactly the oposite, read the reports.
The Swiss came to the conclusion that a Typhoon P1E could not close the capability gap to an upgraded AESA equiped Rafale…
The Typhoon P1E is very much today´s aircraft.
Edge alignment, canted vertical surfaces and fixed radar absorbing structures in the inlet tract on Rafale and EF??
Edge alignment – Yes
Canted vertical surfaces – No, my bad, but pretty irrelevant for the RCS in the frontal arc.
Radar absorbing structures in the inlet tract on Rafale and EF – Long S ducted tunnels, instead of radar blockers equiped with movable vanes on a very short tunnel.
brace yourselves…..:D

Did I really say Black Adder instead of Bright Adder? Oh dear, very sorry, my mistake. As it happens I was actually watching Black Adder on TV as I was writing that out. But who wouldn’t be influenced by such a classic comedy? 😛
That only marks you has a chap with excelent taste (at least for TV series 🙂 ).
AN/APG-79 also gives you lower probability of intercept.
True, but how´s that transforms itself in any significant advantage in a non LO/VLO airframe on a ATA scenario is anyone´s guess, right?
And nevermind that those EF´s and Rafale do have long range passive sensors that are not present on the SH, right?
At an airframe level the Super incorporates greater use LO features; things like edge alignment, serrated edges on major panels, along with the energy absorbent structures in the inlet tract and canted vertical surfaces.
Disputable, very, very disputable.
Every single item on that list of yours is present on the Rafale, and only the serrated edges are absent on the Phoon, and by the way, on another note ,how well does the frontal RCS of the SH behaves at supersonic speeds?
By then the vanes of the radar blocker´s should be entirely open…
Anyone who doesnt have acess to the RCS charts of the SH and the Euro canards his just guessing (badly).
And remember, for some strike missions it will carry JASSM; itself designed to be stealthy.
As for F-15SG. Yes its capable, but it LO?
Didnt understand neither of those two phrases, things like JASSM, Storm Shadow and Taurus are available for integration in every Western Combat Jet.
And that question about the F15SG being LO, is strange, the SH with ATG munitions under its wings is definitely not LO.
I think that you are overestimating the RCS reduction features on the SH by quite a margin.
Clean SH´s are detected, tracked and locked on a regular base at BVR distances by EPAF F-16 MLU using the old (and small) AN/APG-66V2. The SH is not a F-117, or a Raptor.
100 subs and 150 ships will atmost cost $250b (1/3 of armament programe). i am not saying everything will be built before 2020. but atleast money will be allocated and there is nothing stoping them from allocating more money after 2020.
And then you woke up and stopped dreaming.
The reason why LM doesnt (re)enter the FX2 fray with the F-35A is because they (LM) were already “ejected” (together with Sukhoi and Eurofighter) from the competition and the Brasilian Air Force has not been particulary forthcoming to “late re-entries”.
I would imagine that the option to offer the Block 60 Viper a few months after throwing the entire JSF sales dpt to the lap of Juniti Saito when he visited the USA didnt do an awfull lot of good either.
:confused: It’s probably the most capable air to ground aircraft currently in production,
Really?


and in pure air to air still has a lot of +s lacking in EF, Rafale.
“lot of +s lacking in EF, Rafale”
Last time i´ve checked (with public sources of information) the only thing that the SH has that is lacking in “ATA” to a “Phoon” is the ability to track a lot more targets through the AN/APG-79.
Black Adder sure sounds like a cunning plan.
I would be mildly surprised to discover this chap (below) under IPA5 nose cone!

I´ll get me coat… 😀
