Don’t need to. I can open up Jay Miller’s book on the F-22 and see them anytime I want. π You still haven’t explained why AvWeek would talk about them as if they’re common knowledge if they don’t exist. :diablo:
Just go ask.
I’ve seen plenty of bull on Avweek over the years. Journalists are journalists… not infallible gods.
I’m sure you’ll also note the Super Hornet has a virtually identical flame holder arrangement in its nozzle… unless you are of the opinion it has radar absorbing features in its engine nozzle too…?
Oh, you’re really trying hard to make friends and influence people in here, aren’t you?
Watch your language in future, and don’t poke sticks through the bars of the mod cage.
Then all will be well.

*puts stick away* π
In the turbine engine world, nothing is free. Choose any two:
- Light weight
- High thrust
- Longevity
Unless you pay the development money and spend the time, you cannot get all three.
Indeed. Its like the bulls!!t you see managers come out with “faster, better and cheaper”… err no, thats the magic triangle of compromise… you can have 2 at the expense of 1 or 1 at the expense of 2… but not all 3.
But why is it assumed they didn’t spend the development money & time? :confused:
Spain has therefore suggested that the machinery currently at the British factory in Filton, near Bristol, where the planeβs wings are made, be brought to Spain, and the country has even offered to pay the costs of the transfer.
Lemme see.
Is it a good idea to give away the work of the only facility currently manufacturing large scale composite wings for commercial or military freighter aircraft in the UK?
Hand off all that expertise and experience as well as the equipment?
A f**king dreadful idea.
So, yeah, Gordon Brown to sign the deal by the end of the month π
Odds are
… so no materials advances? No blade improvements from increased & improved numerical work? No pre combustion mixing from increased & improved numerical work?
[BTW, you ask your mate dozer about those afterburner flameholders yet?]
Saying the 330 is perfect for the job because you want to sell 330s is silly.
Listen to the customer, they’ll decide what the correct size is for their requirements.
IMO, the 330 will cost much less over the life of the aircraft, hence why I don’t see size as the particular issue.
It is more how much capability can I get with $XXXX dollars?
[Problem of course being, politicans are all too happy to buy now, and let some other sucker pay for it next term… or the next 10 terms – hence why they are almost certain to buy the 767s… which “have”* a cheaper initial acquisition cost]
*Obviously Boeing are going to eventually screw the design at some point after the dotted line has been signed, and then they’ll fleece the DoD for more money… but it’ll be too late to back out as it would cost more to go A330MRTT at that point.
Sorry but it’s the same principle, exactly the same principle
It is not the same principle.
One has a lag, often of several minutes, during which time corrective action can be taken.
The other doesn’t. You know that.
(BTW, in your other post are you saying children these days have never heard alternative expressions for manure*?)
*and no, not man ure the football team based in the north west of england. π
Again, with your argument, why not buy A380s? Or replace all C-130s with C-17 or A400s?
On what ratio could you replace -135s with A380s?
There is a happy medium, and going to absurd extremes isn’t a great argument either!
I do think that the boom has been superior for the USAF since it’s inception, especially for large aircraft
I would amend that to “only for large aircraft”
Refuelling 2 fighters at once is much better than queuing… For the KC-45, the probe/drogue is only capable of ~2500 lb/min, while the boom is around 9000 lb/min. (For an F-15E, thats around 5 mins 20 sec and 1 min 30 sec)
But by fuelling in tandem, thats really 5000 vs 9000… of course, then minus the time taken for the first fighter to disengage and the second to get in position and hook on… which I would expect is a couple of mins at least.
not to mention foul language
I guess you’ve never seen the reaction of most engineers when their CATIA/ICEM/Fluent/CFX/ProE/NASTRAN/Abaqus/PATRAN/Compro crashes?
I can assure you there are a more than a few colourful words in the air.
What you’ve in effect done is tell Deano he doesn’t know how to fly simply because he disagrees with you; a remarkable claim to make. We can all be a little blunt at times (myself included – as pretty much everyone on this forum knows), but you’re taking the p!ss.
Nah, I’m sure he knows how to fly quite well. I’m more cheesed off at the systematic crippling of the entire industry by fears over legal actions. The fear being evident in this:
The problems start when something happens, and then you haven’t got a leg to stand on.
Be that over SOWs, over anal amounts of paperwork for anything and everything or over situations like this.
Common sense has long since disappeared… and it pisses me off no end.
When is the last time you were allowed to give a friend or family member a lift in the jump seat Deano? Common sense eh? I think its a disgrace how cowardly the authorities and airlines have become.
Not to stand accused of being biased in any way, that also extends to the OEMs/supply chain, but in a slightly different way.
If fears over legal actions were removed, I guarantee you that the design times for aircraft would decrease to at least 2/3s their current timescales. Procurement are destroying airbus from within right now. If they don’t get their act together (or better yet, be removed totally and let the ETLs handle it directly) and there won’t be an Airbus in 20/30 years time… Comac or the Russians will have moved in and killed them off.
{As for my grammar; I get paid to write properly in work. I don’t get paid to give a here}
Not until it’s been demonstrated. It remains to be seen what the production model will look like, based upon whatever changes end up being made.
But…. being even handed… the F-35 has not demonstrated anything yet (in that regard).
Unless you are going to take the world of LM et al, and dismiss the word of Suhkoi etc… which is not exactly being objective, is it?
The guy you’re directing that spectacularly arrogant rant at currently flies for a large UK airline. What’s your experience? It would be good to know why you seem to think you’re in a position to essentially tell a professional commercial pilot he’s talking crap. :rolleyes:
If he doesn’t have the capacity to recognise a dodgy radio transmission, then he is getting paid too much… or is too stiff to operate outside of strict routine, i.e. when something goes wrong (which incidentally is now recognised as the biggest problem with commercial aircraft safety – too many pilots have forgotten how to fly! Don’t quite know what we do to fix that…).
In answer to your question, I design the things he flies.
A better argument, but still lacking. I’ve re-shuffled some of you points to better address them.
My argument hasn’t changed… it just has more explanation to it.
This isn’t the issue with the -135, in particular the E models which are the most in need of being replaced. The particular problem with the -135’s aren’t the parts, but the extensive fatigue and corrosion (often acting together). I’ve walked the PDM line multiple times at Tinker and am well aware of this. These tankers needing replacement are melting away due to corrosion. Often times the parts cannibalized are major structural assemblies. These are salvaged off of the bone yard aircraft b/c it’s cheaper than manufacturing new parts.
Bingo. π
Now, on the first point it is the same case for the A330 when you look at the expected time line on the procurement. By the mid-2020’s that line to will be replaced by the A350.
See above, but by 2025 it to will be replaced by the A350.
Yet, that line will be supported commercially for at least another 20 years from now… what is the average lifespan of a freighter? Add that to the line closure date. π
The point made with the examples mentioned is that the airframe risks are low. The folks in Seattle have been mixing and matching since the 60’s with the 707. Now, systems are a different story… Frankenfreighter, emotional arguement, won’t start debating, “So, when did you stop beating your wife…” arguments.
Still think the 767 is low-risk?
Also a departure is this boom design that is pictured. The design is more reminiscent of a KC-10 boom rather than the KC-135. It is likely this switch was made to achieve the 1200 gallon per minute offload rate demanded by the KC-X. The boom offered in the last competition, which Boeing lost in February 2008 to a Northrop Grumman/ EADS team, used a ruddervator structure more like the KC-135 boom.
Boeing has been dealing with the flutter issue on its international tanker design, and the wings on this 767-based tanker appear to be significantly longer than a baseline 767-200 commercial model.
How many changes is that Boeing have made inside a couple of years? I’ve no problem with changes, “only a fool doesn’t change their mind” and all that, but it does mean they do not yet fully understand the aircraft.
You simply cannot turn around and say that is equal in risk to the A330MRTT which is already flying and transferring fuel very well.
The informed debate will be based on the evaluation criteria laid out in the RFP and how one side or the other best meets the requirements laid out there in.
Please. Its political football now.
Whatever the USAF get now, be it the B767 or N-G KC-30, they would almost certainly have got a better deal* if the politicans had stayed out of it.
*they may have gotten their replacements in the air before the -135s fall out of it.
What a crock…. in years gone by flight crews from different airlines would dead-head with other airlines.
Now its all… hell no we dont trust you anymore. Lock everything, in the event you both become incapacitated no one will be able to break in to save the day.
Yeap.
Same sh!tty attitude which has got that ATCler in NY in trouble.
The world is going to the dogs… and its being led there by lawyers. π
