Debate on F-35 JSF aerodynamics

Dear Aussie Digger,

Not much point talking budget if you are not prepared to sensibly discuss the figures.

The simplest of arithmetic shows that more than enough budget already exists to provide Australia with the best air combat capability, in the most cost effective way and at the lowest risk while ensuring the Australian Defence Aerospace Industry remains intact.

Though now a little out of date and still awaiting final input from the peer review by Defence (some has already been received), you will find the bulk of the budget figures in the Total Project Cost Comparison table at -

http://www.ausairpower.net/media.html

The now $31+ billion already required to support the Minister's current plans (the F/A-18F interim solution was not a Defence recommendation nor decision so this should not be sheeted back to them) for the next 13 years is more than adequate to cover the greater capability of the F-22/Evolved F-111 Option and still leave well over $10 billion in the capability development kitty.

Realise you are likely to disagree, so let's see the results plus associated references and assumptions of your costing analysis. Nothing like a bit of professionalism to spur on a good debate.

;)
I have no financial interest in the outcome, so why should I bother spending the time researching the open data that you love so much? You've intimated previously I spend too much time on these forums anyway...

It seems however that you have made a profession out of researching US Government budget papers and selectively quoting them.

Was the US$175m per F-22, EACH (in FY06 dollars), figure I mentioned earlier wrong? US Congress doesn't think so...

Tell me why BKNO, it's what you CONSISTENTLY fail to do. BACK UP what you say with SOMETHING.
Well actually if you are in need for basics physics you can find numerous SOURCES to learn the ABCs of the buziness, this topic is here for the purpose of comparing aerodynamics and accessorly shifted to IR signature of engine designs.

AND: Backing up WHAT? The right assumption that for a similar exhaust temperature one extra layer of cool air is lowerering the IR signature of an engine?

Wants photos of the M-88 and F-135 for comparison???

Aussie Digger Tapping your nose and saying trust me gets you nowhere.
All you have been doing so far is getting at me at a personal level and accusing ME of doing what YOU do and of not providing with evidences while ignoring and dismissing the one i post.

I never said the exhaust nozzle wasn't definitive. I said none of US have seen it the production nozzle YET.
So the difference is??? AGAIN you might be knowing some L-M doesn't but then, go tell them their structural design isn't frozen yet, that they need to redesign their engine BAIES and add an additional inlet to feed it with low-pressure cool airflow that will be exhausting AROUND the existing nozzles and cool them as well as the engine airflow....

I'm SURE they're going to LOVE this.

To lower the airflow with the SAME level of technology FIND another solution than adding another layer of cooler, uncompressed AIR.

You can check on this all you want, this is a simple matter of the most elementary physics.

F-135/136 doesnt posses a secondary, cool airflow duct like M-88 and if you cared to inform yourself on the matter you'd KNOW that USN/USAF/NATO pilots already report problems locking IR AAMs on the actual aircrafts equiped with M-88 but then again you're going to cry out for evidences now......
http://img91.imageshack.us/img91/9001/2e4ecofr3.jpg

So i am asking YOU to provide US with the evidence that the US engines have similar design and IR supression features which is quiet visible with the secondary fixed nozzle visible around the more conventional con-dis.

I KNOW for a FACT they DONT.

Another FACT: They (F-119/135/136) RUN HOTTER than M-88.

Just checked the APA link. Again its completely incorrect like the stats you posted in the Super Hornet thread that got locked.

50 F-22's cost 9.1 billion

100 F-35's cost 15.5 billion

That means the F-22 will cost 182 million each and the F-35 costs 155million each. That works out to the F-22 costing only 17% more!!!

Now thats absolutely false and completely made up using the lowest price for the F-22 and highest price for the F-35. Comparing projected prices of an aircraft in LRIP against an aircraft in full rate production is like comparing apples with oranges. Defence see's right through APA's incorrect facts.

The cost of the evolved F-111 is also completely unrealistic. I dont even know where to start as it boggles my mind.. They dig a deeper grave with everything they release.

Of course, but they are not really interested in debate. They are interested in support, as they hope a sufficient amount of this may sway whatever elected representatives are in power to proceed with their proposals for the evolved F-111's.

What's actually best for Australia has NOTHING to do with their arguments.

Defence gains NOTHING from engaging in debate with APA, even if APA is 100% correct, which seems difficult to believe in an at least "2" sided debate.

The Joint Standing Committee on Defence Foreign Affairs and Trade has already stated that it is satisfied with Defence's response (most of which occured behind closed doors) to APA's submissions.

Articles like that posted in the now closed "F/A-18E/F versus SU-30" are simply rehashed submissions provided to the Senate Committee.

The Committee is satisfied with Defence's arguments and the Government is too. Labour has recently admitted they support the F/A-18F acquisition, the final "G" model F-111's are already being retired and the "C's" (now with Labor's blessing) will be retired from 2010, with the "draw down" process to their final withdrawal underway soon.

All we are seeing is a "last ditched" effort and one that has been repeated ad nauseum at that...

Here are the visual evidences of the difference between the F-135 and the m-88.
http://img503.imageshack.us/img503/1835/comparedirey6.jpg
Even if "Non-scientific" and only visual it is pretty obvious that M-88 posseses a duct runing from the root of the air intakes (A; between the diffusers and the fuselage) and the hot con-di nozzles.

These scoops doesn't FEED the avionic baies during flight, they are cooled in close circuit.

This feature allows for a partial shielding of the nozzles as well as the cooling of the hot exhaust and works wonder, there is NO increase of temperature as for normal engine baies cooling systems due to the of absense high pressures.

Picture B even allows to distinguish between the two airflows, to be compared with the exhaust of the F-135 as mounted on the F-35, and the M-88 layout (D) showing the root mechanism of its con-dis shielded under the composite-ring.
http://img292.imageshack.us/img292/9941/spliirjetengine110dc4.jpg

This ONERA IR spectrum shows how it actually work in static test, under certain angles the con-di nozzles and their hot spot would be invisible.

http://img411.imageshack.us/img411/7006/rafaledettuyeredsc0004cm1.jpg

I think it's pretty obvious that whatever way you want to put it, running hoter and being less developed at this level is hardly going to help the F-135 to reach lower IR signatures.

I'm out of my league here I admit it, but tell me, does the 2 engine design v 1 engine design bear any factor here?

The F-135 engine as you have correctly pointed out most certainly IS running hotter.

To the tune of 43,000lbs of thrust as of September 2006... :unknown

I don't recall stating that, but given we don't know the B2's exact capability, this would appear to be a non-sequitur wouldn't it?

What is it with you AD??? We dont know the exact specifications or capability, so and therefore you are unconfortable with assuming theat the B2 has a more effective LO system than the F35???? Geesh!!!!

And anytime i mention the limited nature of the F35's LO your object to it, which would inidicate you dont agree.

I don't and never have suggested the F-35 will be the best at "everything". What I do think it will be, is the best SINGLE FIGHTER for the RAAF in coming years, given the breadth of roles the RAAF is required to perform.
But you object to any critisism of the platform, and rebut it with a quote of someone from LM saying how good it is. Again this would indicate you dont agree with said critisism.

As far as a SINGLE FIGHTER soloution, I agree. The F22 (if it were for sale) is just too expensive, and no other platform is as capable in as wider variety of roles for a similar investment. however i dont agree with the single fighter concept. the platform was intended to function as part of a high-low mix, and therefore lackes some important capabilities. Not to mention the risks with a one platform air force. If there is a generic problem in the whole fleet, the RAAF could go into Air cargo for a while.

Could the RAAF technically be enhanced beyond this by the inclusion of F-22 or some other "high end" fighter? Probably.

Will the budget exist though to do this? Unlikely.
A single squadron replacement with F22's would grant us a practicaly unbeatable force structure, on par with the USAF.

if we really wanted it we could afford it. We're in one all mighty surpluss at the moment, and as long as the Coalition stay in power there should be enough money floating around for a squadron sized purchase without too much trouble.


As will every OTHER platform.
I'm not being sarcastic, but what are you refering to in this comment, i'm not realy understanding what this is actually refering to??????:confused:

The F-35 though has the ability to employ standoff weapons from it's internal bays, to ranges that the F-22 cannot match with ANY weapon in it's inventory...
For one thing the F22 dosent need to employ stand off weapons, its LO renders it pretty much untouchable for most IADS so it can just fly over the target and hit it with a J series free fall weapon (JDAM, SDB).

Also, external carriage pods that are under development will alow the F22 to carry a wider variety of weapons without comprimising its LO. (obviosly this will comprimise its performance, however this is less important when on a strike mission). With these carriabe pods the F22 can carry all the weapons the F35 can carry internaly (JSOW, NSM, note that JASSM has to be carried externaly). Have a look at the bottom of this post.

So it doesnt need stand off weapons for most occasions, and with underwing hardpoint carriage it can carry more of the same inventory without compromising its LO.

Ground based EO/IR systems are going to be LOS limited, which probably explains why they don't seem to be employed on anything besides MANPADS and AAA, though I am happy to be corrected on this point. I am certainly no expert in this field nor have I read extensively on it, but I believe this to be the case at present.
I was refering to its consequenses in the A2A combat environment. As far as the SAM/AAA threat, you would think that due to weather conditions and LOS advanced IR/EO systems would be restricted to the low level environment, and therefore will have far less of an impact than its aplication on other fighters.

Don't forget about the miniature stand-off missiles currently under developement. The LOCAAS and SMACM are very small stand-off weapons designed to fit in the Raptors and probably Litening IIs weapon bays. Newer JDAM and SDB additionally use wing kits for extended range, enabling even the Raptor to perform stand-off attacks. The point is that the Raptors avionics aren't designed for AG operations. Of course many things could be changed with help of new software or partitially replacing existing sensors with new ones. Further developing the Raptors MLDs into a multifunctional IR-sensor suite is a strong possibility.
In terms of costs I'm still not convinced that the F-35 is going to be a low cost aircraft "cheaper than all other new gen fighters". Total programme costs has by now increased at over 30 %, while the total numbers were reduced. LM is still not will to guarantee fix fly-away prices for a very good reason. And ~45-62 mio. USD is already significantly above the originally projected cost of 28-38 mio USD depending on the version.

Just the Professional Way of Looking at Matters . . . .

This is an interesting comment for you to make. All other Australians have a financial interest in this matter. The F/A-18F will cost over forty million dollars per electorate and the overall cost of the current plans will be in excess of two hundred million dollars per electorate while the savings to be made by adopting the plans that are supported by detailed analyses which have also been validated by independent analyses done in Defence would be more than sixty million dollars per electorate.

Do the arithmetic if you don't believe.

As to the time you spend on these forums, that is none of our business and really has little bearing on the discussions. However, the quality and veracity as well as the tenor of your arguments does.

It seems however that you have made a profession out of researching US Government budget papers and selectively quoting them.
Just because some people are incapable or choose not to do the research does not mean that others can't or don't. After all that is the professional way to approach these matters.

Please point out where your claim of 'selectively quoting them' is supported by fact. In the posts where the Pentagon and US Govt Budget Papers have been cited, we have posted the actual data from these papers. Clearly, you need to use sophistry, mendacity and spin to support your belief system but you should also realise this goes to your credit.

Was the US$175m per F-22, EACH (in FY06 dollars), figure I mentioned earlier wrong? US Congress doesn't think so...
Not entirely, just not applicable as has been stated previously - mainly on the threads and posts that you, as the super regurgitator, have removed or shut down.

This figure along with the US$153 million AUPC cited by Angus Houston in his Strategic Insight back in 2004 are representations of the Average Unit Procurement Cost from the current production for the USAF (the 184 units). Neither Australia nor Japan nor any other prospective procurers/lessees of this technology can access this production run. Any access to this technology would be over and above the 184 presently in production and, as is being claimed for the JSF Program, the more you build the cheaper the unit price gets. Pretty simple, really, don't you think?

:rolleyes:

It may do however the contract has already been signed and the money spent. It's much like your inclusion of the HUG program in your "cost analysis" of our future air combat capability. You don't of course include the F-111 AUP or AGM-142 acquisition costs in your diagram because they don't help your argument, yet they are every bit as relevant as the HUG funds that have already been spent...

Well once again you resort to an "Ad Hominem" attack to attempt to make a point. But's it rich that you refer to me as a regurgitator. You and Dr Kopp have no choice but to regurgitate the work of others in this debate, because you CANNOT access the data that RAAF has.

Selective quoting? You did it a couple of days ago pointing to Loren Thompson's comments that F-22 could easily be made available for export. Of course Brigadier General Kohler states otherwise, but hey, again that hardly supports your obsession does it?

:rolleyes:
It may if the US decided not to impose any levy for the enormous development costs of the aircraft on any prospective foreign acquirer, nor bothered charging said foreign acquirer for upgrades (or should that be downgrades?) Nor bothered charging the customer for the upgrades even the USAF admit would be necessary to give the "multi-role" capability we would need...

Doesn't seem very likely though...

Spot on. Defence see's right through this charade and APA has lost all credibility with them.

The average Australian who is uneducated on the topic will go "wow look at the pretty graphs and look at how much money we can save!!"

For example Air Power Australia could state: "The SU-30 has a slim chance of photon torpedo's and hyperdrive being added to the aircraft in the region". In a way they aren't lieing. APA will then post graphs which happen to be based on the aircraft with said torpedo's and hyperdrive instead of the realistic capability. They will exclude the figure 0.0000001% chance of either technology even being invented yet let alone being added to the Suhkoi's, yet they use the words "slim chance". This is what they have done with the AL-41F and the ficticious stealth/streamlined weapon bay between the engines of the suhkoi. Neither of which will ever be used by Indonesia. Notice how i said ever? Thats an APA tactic. Its probably a 99% chance Indonesia will not get these but ill smudge the figure to 100% ;)

Another example if you have an aircraft who's range is 900 miles and one that is 1000 miles. On a graph you can change the scale so that the bottom of the graph is 800 miles and the top is 900miles. So even though one aircraft has 10% extra range the bar on the graph is twice as long.. Air Power Australia do this all the time. For example to compare an aircrafts radar If you had two radars one with 1000 AESA modules and another with 2000 AESA modules.. Air Power Australia would then put a bar graph showing the larger radar with a 100% increase. Yet in real life the detection increase would not even be 50%. Air power Australia would then totally exclude the fact that the aircraft with the smaller radar has a much lower radar cross section So the the smaller radar'd aircraft would detect the other aircraft well before, yet the graph says otherwise. This is selective reporting/researching/quoting. Or as i like to call it, lieing.

ANYONE who has half a brain on the topic will see right through Air Power Australia.


Anyway the F-22 will cost 317 million each (a) and the F-35 will only cost 38 million each (b) so nearly 10 times as much. That statement is 100% correct!!!

It's somewhat sad that I feel the need to suggest this, but I do. Perhaps it might be a good idea for the Oz SH/JSF/F-22/etc al threads to be put back in to cool off, but this time stick them in the freezer for a wee bit longer.

I would like to see a serious, reasonable and polite debate, but it seems to have already descended to ridiculing and name calling again.

Webbie/mods, it's your call.

Sigh....I didnt want to get into this debate with you again rimjas, but since the below comments are indirectly aimed at me, because i sighted APA in my argument and therefore have only half a brain, i feel obliged to defend myself.

So mods dont blame me if this thing goes the way of the last little debate on the future of the RAAF were APA was brought up.


The average Australian who is uneducated on the topic will go "wow look at the pretty graphs and look at how much money we can save!!"
I dont agree with the F22/F111S idea and i daont agree with some of APA's analysis on this topic. There are just to many maybe's is the plan for accurate cost projections to be maid, so i am somewhat scheptical of the numbers given on the F22 (does it include lifetime costs) and the rebuilding of the F111, which is frought with risk.

For example Air Power Australia could state: "The SU-30 has a slim chance of photon torpedo's and hyperdrive being added to the aircraft in the region". In a way they aren't lieing. APA will then post graphs which happen to be based on the aircraft with said torpedo's and hyperdrive instead of the realistic capability.

This is were you and me part ways buddie.

Here are just a few things wrong with what you have just said so simplisticly (i'm trying to be nice). By the way everything i am about to say i have said before so i am sure you are well aware of why the above statement incorect.

For some reason you only consider indonesia a threat nation, or a nation that needs to be considered. When the two nations (with current capabilities mind you, not the ones under development) who actualy have some capability to project power into the air/sea gap and northen australia or i.e. pose a threat, are India and China. And dont start saying that a war with them is so unlikely that they dont need to be considered, because its about as likely as a war with indonesia, which you seem to consider a threat.

Do you know what stage of production the AL41F powerplant is in??? LRIP or Low Rate Initial Production. That is about the same stage of development as mauch of the F35 programe. And given the HUGE expansion in the export market for flankers and upgrades for them in PROC, India and SEA, could you explain exacltly how the russian are going to have trouble selling this in their next evoloution of flanker or as a powerplant upgrade, given its capabilities???? Because the way i see it its about as likely as ever seeing an F35 in RAAF colours. Your right it is about as likely as photon torpedoes huh???? Its intersting how you continually speak of future Australian capabilities as absolouts, but relegate the posibility of future threat capabilities to, how did you put it, "hyperdrive, photon torpedoes, and 0.0000001% chance". It seems you are more culpable when it comes to an inbalanced argument than APA, since you think the F35 will be some sort of a super fighter capable of doing anything, and the posibility of threat aircraft improving at all is so ridiculous to even consider it is evidence of stupidity.

Another example if you have an aircraft who's range is 900 miles and one that is 1000 miles. On a graph you can change the scale so that the bottom of the graph is 800 miles and the top is 900miles. So even though one aircraft has 10% extra range the bar on the graph is twice as long.. Air Power Australia do this all the time.

Air Power Australia would then put a bar graph showing the larger radar with a 100% increase. Yet in real life the detection increase would not even be 50%. Air power Australia would then exclude the fact that the aircraft with the smaller radar has a radar cross section 1/1000th the size. So the the smaller radar'd aircraft would detect the other aircraft well before, yet the graph says otherwise. This is selective quoting.
If your going to make accusation like that it would be good to give some evidence, lest you look foolish by making childinsh, immature and overly simplistic accusations. Note the bottom of this page, three graphs i picked up from the APA website. Both show the whole length of the graph, not just the "top section" in order to exagerate any difference. 10M2 RCS to 0.001M2 RCS is pretty comprehensive. They dont "change the scale" to exagerate any differnce. They may not take track radii or EA into account but they dont claim to.


Anyway the F-22 will cost 317 million each (a) and the F-35 will only cost 38 million each (b) so nearly 10 times as much. That statement is 100% correct!!!
:eek:nfloorl: thats a lame attempt at sarcasm.

Could you back up your accusations with SOME evidence please????

In general terms the argument behind the F111/F22 idea may indeed be flawed and Kopp does have a personal/finantial interest in it. However people like Mr rimjas will use that to render any arguments made by APA as irrelevent because they dont like it upseting the warm, fuzzy feeling they get wgen they think of the F35, even though it is an argument based in factual analysis. Someones intention is irrelevent if their argument is backed up with EVIDENCE, which APA does. Now their analysis may be flawed to some extent, if so make a factual argument of your won to rebutt theirs, dont just make childish accusations.

P.S. it is slightly hipocritical to accuse APA of makeing simplistic or biased analysis, when you did use high school phisics equasions to support youtr argument concerning the F35's kinemetic performance. Perhaps your attitude towards any advancements in the flanker family can be seen in a similar light???

Mods, i am more than willing to have a cool headed dabate on the issue, I admit the F18F thread did get heated and i was partly to blame.

However this is a very important area for debate and closing all said threads just because some members cant keep it from getting into name calling. So take that in mind before you stop all of us from enjoying the discussion.

The F-22 will cost more than the F-35 but where on earth did you get these figures from? :rolleyes:

Whilst some of the propositions made by APA seem flawed to me I accept that there is some very good information on their website. I disagree with the F111S/F-22 proposal but I would support an F-35/F-22 mix if the F-22 is ever made available and if could be purchased at a price that will not bankrupt the country.

I think that even if the Oz discussion gets heated It would be a pity for all discussion re the F-22/F-35/SH to be banned as it is also very relevant to other countries, e.g. Japan, South Korea and of course the US itself.

BTW, would it be worthwhile combining all of the OZ air combat threads?

This is selective reporting/researching/quoting. Or as i like to call it, lieing.
Uh oh...something's wrong here...I actually agree with something RJMAZ said! :hitwall

I agree that all bar or line graphs should start their X axes with 0, not at or near the lowest number in the comparison, although this isn't something that has jumped out at me as being a telling feature of APA's comparisons.

OT - It does annoy the hell out of me when you see the various news networks showing the supposedly wildly fluctuating stock market closing figures of the past X number of weeks, months or years, but using only the lowest figure of that period as the starting point of the X axis to exaggerate the rises and falls!

Anyway the F-22 will cost 317 million each (a) and the F-35 will only cost 38 million each (b) so nearly 10 times as much. That statement is 100% correct!!!
Oh well, I knew it couldn't last. :rolleyes: Try about A$200m each and A$115m each respectively using roughly comparable non-recurring flyaway costs, and then add support, infrastructure, a weapons package, and a few block upgrades to that figure. It is estimated that to make the F-22 available for export, roughly A$1.5bn would need to be spent dumbing down or sealing whatever systems the US are sensitive about. I believe the Block 20/30 and maybe 40 spiral upgrades which would give the F-22 an EO-IR sensor, and moving target and anti-shipping strike capabilities are included in the US$70bn total program cost, but some or most of this additional funding is yet to be approved by Congress.

If you really want to divide program cost by airframes (which is not a true apples vs apples comparison due to technology flow downs and cross-overs between programs, e.g. APG-81, APG-79 and APG-80 technology insertions to the APG-77(v)1), currently the F-22 is tracking at around US$350m each (~US$70bn for 184 airframes), while the F-35 will average out at around US$100m (~US$300bn for 3000 airframes) spread across the more expensive but fewer in number F-35B/Cs, and the cheaper but more prolific F-35As. The F-35 was NEVER going to cost $38m in recent calculations, in any currency!

In the unlikely event that Japan and, say Australia, were to take a further 150 F-22s between them, this per unit cost would obviously drop quite substantially. There is also the possibility of the USAF taking more than the 184 currently ordered, further reducing the unit cost, and also making the spiral upgrades far more likely to be fully funded.

I think that even if the Oz discussion gets heated It would be a pity for all discussion re the F-22/F-35/SH to be banned as it is also very relevant to other countries, e.g. Japan, South Korea and of course the US itself.

BTW, would it be worthwhile combining all of the OZ air combat threads?

Cheers
I don't want the topics to be banned. It just seems right now, they keep devolving into personal attacks, usually involving the same culprits as have caused the threads to be locked for cooling off periods before. Therefore I think a longer cooling off period might be in order.

What I'd like to see is less <insert male bovine scatalogical reference HERE> as well as unsupported statements of who/which country is better at making widgets. Instead, I'd like to have a discussion on where and how the F-22/JSF/SH can and should be used.

I'm not sure that it's possible to conduct such a debate at present given the ongoing rancour.

Just to point out , guys that we are FAR from the original topic subject.

At least with the price issue. since perfs are th result of aerodynamics and thrust i wont mind too much but i feel that this topic have been hijacked...

Hey, maybe we need another "F-22/F-35/SH for Oz"-Thread... ;)

Seriously I think this topic is interesting to read but since some time every thread which only comes close to one of the mentioned planes results in the same discussion. And this for dozens of pages.
I know that we have a big Aussie community here but in my eyes it is just too much. Concentrating on one thread would be really nice so other threads like this one could stay unharmed of this discussion and be purely about the intended thread topic.

cheers :)
