Warpig , I like your last post very much . I wish the other known and usual posters would do the same , I mean thinking before typing , taking the time to do research and understand what is at hand . We must thank Herald (I already did) to give us such usefull material with that study . I did not know of Prof. Fleeman but he is obviously an expert . His maths are well beyond mines , light years away I must say . But I understand the study good enough to be able to talk and argue about it .
Back to the topic .You said :
CREF bolded:Take your own advice, fanboy
""On Slide 42, that's the shape of the typical boost + sustain motor in missiles such as AMRAAM. MICA's motor is all boost, and only has the first vertical rectangle. Now look on Slide 46, that's the shape of the typical velocity curve of a boost + sustain missile like AMRAAM. MICA's would be just the boost portion immediately followed by the coast portion. Then Slide 47 is one way to show how that velocity over time translates into distance flown.""
Your analysis wouldn't be complete without looking at the slide 51 and 52 which show the gliding . Then , you have to add the slide 34 and 35 about initial velocity . It is the reason why I (and the numbers) can 't entirely agree with you . I explain by using your words :
""MICA will boost for a few seconds and peak at M4+, maybe about M4.5. After that it is coasting toward its target.""
Specifically 6-7 seconds, then flameout. After that it is lift drag, gravity and that is all. The rocket begins falling immediately and loses energy once thrust ceases.
What people should take into account is HOW a missile is coasting to its target . In this regard , all missiles are different . Different diameters , different weight , different size to length ratio , different surfaces , different canards (if any) , different wings (if any) , etc . It is very complicated . MICA has its advantages and they are not just only few . More on this in a moment .
A missile falls using the same physics (ballistics) that every falling object uses.
I will discuss why BW is full of horse manure at that time-since it is obvious from reading this CRAP that he got someone to explain to him these charts and generic graphs, that he doesn't understand at all. What he's apparently done us talk to someone with just a bit more knowledge than he has and he has latched onto a few concepts and buzz words without reali8zxing exactly what the other pwerson tried to explain to him. .
""AMRAAM will boost for a few seconds up to M3.5+, and then sustain for another ten seconds or so, and get up to maybe at most M4. After that it is coasting toward its target. If the AMRAAM curves look like the ones in the briefing, then the MICA curves will peak higher during the boost phase, then proceed to taper off during the coast phase. What will happen if overlayed on Slides 42 and 47 is that the MICA curve initially peak higher than the AMRAAM curve, but then because the AMRAAM is still boosting while MICA is already coasting, MICA will at some point cross over the AMRAAM curve.""
10 seconds+ The AMRAAM has a tandem burn rocket motor like many extended range A2A missiles. The Super 530D in its latest longer iteration (German technical help) also uses a tandem burn motor. What that means is that the first burn part of the fuel candle burns sharply with as great as a specific impulse as you can manage for acceleration to its best cruise Mach number for the rocket aeroshell. This typically is around Mach 4-5 for a missile like AMRAAM. That will be around 2-4 seconds depending on the rocket. Then the long burn part of the candle is consumed at a reduced specific impulse to sustain the that velocity over the rest of the flypout. This means that rockets whose size would normally doctate a sharp burn of less than 10 seconds and a maximum velocity of around Mach 6.5 can trade a little velocity for endurance and Range as the rocket uses the extra burn time to exploit LIFT.
This is exactly the REVERSE of what happens that the fanboy claimed above. You will notice in a previous post that I pointed this out and that he missed this? It is why I used the 530D (long) as the example to ullistrate that even the French recognize this sumple fact. Using a tandem burn candle in the 530 D literally doubled the flyout and engagement MER of that rocket from something a little shy of 30 kilometers separation at a head-on pass same altitide launch aircraft to target to something just over 60 kilometers MER same conditions.
Nope because MICA glides twice better than AMRAAM . It also offers better end game manoeuvring .
L/W calls you a liar BW.
Numbers
MICA 3100/160=19.375 + [4.844 (25% for strakes lift)- 2.906 (15% for strakes drag)]=21.259
AMRAAM 3660/178= 20.562 and with no strakes those numbers are within 1% of lift.
AMRAAM has very roughly 0.96% the overall lift efficiency of the MICA. 4% is still a significant edge, but the BW LIE is still a LIE.
""Translation: MICA can get to the target faster than AMRAAM if the target is relatively close (say maybe out to 5 to 10 miles away at time of launch), but AMRAAM will actually get to the target first if the target is relatively far away at time of launch""
This is correct.at the AMRAAM midranges. Tandem burn candle means longer sustained maximum sustained velocity over flyout for the AMRAAM. Means that the thrust ,drag, and lift plus gravity COMBINED is doing more work on the rocket body longer. PHYSICS. Four forces act versus two (gravity and DRAG) on MICA.
No . MICA will get to the target before the AMRAAM at up to 20 miles . After , AMRAAM will slowly come shoulder to shoulder with MICA (at 30 miles) then both missile will be gliding (AMRAAM having a slightly better speed at that time) . At that point AMRAAM sinking rate will be superior to MICA because it hasn 't chord wings and because its rear fins do not provide as much lift as MICA 's .
Another lie: MICA tops out at roughly 7 seconds. Flameout comes after about <7500meters and then velocity dies RAPIDLY due to drag {strakes}. This will decrease rapidly over tau so that the break even will be at 30 kilometers not miles.
Assuming 4 second sharp burn and 6 second sustainer burn on 6the ASMRAAM we have flameout at 11000 meters. THEN AMRAAM because of her cleaner and less draggy aeroshell and .96 the lift of the MICA will outreach her competitor by a significant margin with enough residual piytential; energy left to hot at TWICE the effective MER at most aspects. The fools who de3signed MICA were aiming for a Missile that could explout the CRAP RBE2 radar. Rough rile of thumb is that the radar has to see 3x the MER of the rocket it supports. The idiots at THALES aimed for a radar in the 160 kilometer detect fighter sized object range. The MICA is designed specifically to that requirement-right down to the single sharp burn candle rocket motor. MER is l;ss than 80 kilometers distance by separation-and with the design degfects in that rocket its actual MER is that of a direct look track lead missile.
The "old" French Matra Super 530D was already known for that very reason : (quote)
Liar. The Matra Magic is a WVR missile The 530 D us a tandem birn missile these days that doesn't even work like a MICA-so who are you trying to kid? SARH tandem burn rocket that works versus a ATG sharp burn single thrust rocket whose RH seeker is myopic and whose telemetry update doesn't work at all?
"This missile , with its unsual fin configuration , was able to outflying any other air-to-air missile of its day with the sole exception of the Phoenix"
The Phoenix (a better rocket with a better Pk than MICA) was based on the Falcon Genie-a 1950s design. Back then strakes were needwed for pointing at a target as the thrust vectoring nozzles opf the day were primitive. Rockets have improved McGee. France is stuck in the 1950s?
It could also reach Mach 4.5 and that was in 1988 .
Look at the top-out for SPARROW, dummy, 1961.
You also said about the AMRAAM :
""and also actually have a longer range overall than MICA""
Sorry , not proven yet .
Just proved BY THE NUMBERS.
""I am certain Dwightlooi, Herald, Phaid, and Leroy would all back me up on this, and if you had any rational common-sense, that would be enough for you to accept it's true, regardless of whether you think it should be true or not.""
I just explained why I disagree on some points . The fact is that France did not try to beat the US missiles (others already did) but tried to build a missile good at everything . Don 't give me the "jack of all trade" BS , MICA is as good at WVR than at BVR . Very few missiles are better than the AIM-9x and AMRAAM , MICA being one of them . The others :- ASRAAM . The ASRAAM is unique in current WVR missiles, using a very high impulse motor to accelerate the missile to speeds faster than any WVR missile, and providing range performance competitive with many BVR missiles. While the missile does not use thrust vector control, its high acceleration permits similar tight turns post launch, allowing 'over the-shoulder' shots from aircraft equipped with HMS .
And you make this BS up as you go along.
The ASRAAM is unusual in that it uses a very AMRAAM like architecture in its rocket motor. Sharp burn start then a short timer sustainer. The rocket also uses a TVC scheme that makes it competitive with Iris-T as a turner. It is a FAR more advanced design than MICA and probably far more effective as a WVR than many credit it. I will say that it is the BEST British rocket for what its intended to do that I've ever seen.
While I doubt of its end game , the ASRAAM is an excellent design . AIM-9X is probably a better dogfighter .
A2A Missiles don't dogfight, fool. They chase you. What you wanted to say was that you think the AIM 9x was a better close pass to target high off boresight lanuch and chase missile. You would be wrong as usualm buit that is what you tried to say. The correct statement is that the AIM 9X is like the IRIS-T, more agile in the turn than the ASRAAM and with an IR seeker with a slightly. better designed sensitivity, better spoof proofing and wider FoV for the close turning fight. .
Rafael Python-5 . This one is as deadly as it gets . It works with a two-colour FPA detector, similar to the AIM-developed QWIP FPA , a generation beyond the single colour InSb FPAs in the ASRAAM and AIM-9X (yes , check it) . In fact , its IR seeker works in a similar manner to the one on the IR MICA , a dual band imagery with integrated cooling .
Read that one out of wiki, fanboy?
-AA-11 Archer . The R-73M variant increased range and improved off boresight capability to 60 degrees. The latest R-74 includes digital processing techniques, and is claimed to have a 75-degree off boresight capability. It is likely that future R-74 derivatives will include FPA seeker technology . Another deadly dogfighter
Yep either that or you cut and pasted it from some air combat game you have stashed away somewhere-fanboy. PATHETIC.
My mistake. You pulled that crap off Air Power Australia from GRISHA, ROTFLMAO!

**********
Now , Leroy ... As usual , very poor talk but let 's start with something obvious :
""The seeker of a missile is not a substitute for a real IRST""
Here , we agree but it is still a usefull IR imagery at up to 35km . Thanks to JP.Bergerac and his brilliant post no long ago , we know now that a passive shot is possible with IR MICA and the LRF only . AIM-9X and AMRAAM equipped fighters can 't .
1. IR blob detectors are not imaging cameras, dummy.
2, And I read that other dummy, too. No range-no drop basket as you've been told for years. QUIT trying to pass that LIE or cite another fool to bolster your own lying.
""The Rafale wasn't truly operational until what? 2004? (and even then with only a handful of aircraft) Having a few radars flying around during an R&D program is not "operational." ""
I say :
You answer with :
""lol, sorry kid, it isn't that easy. Even a basic understanding of the principals at play here would give you the answer, but you don't want a real answer. You prefer your fantasy that the Rafale is something it isn't. I am not going to waste time proving the sky is blue to you.""
Lolol ! What a beautifull argument , I am impressed ...
I 'll try to answer to the other posters later , when I 'll have time again .
Cheers .
As you can see, fanboy, I not only proved you wrong, and as usual a liar, with simple math and open source knowledge, I didn't even have to reach for any esoteric knowledge to do so.
