I have to say that I am surprised to see every one focusing on a commercial approach. What can be done to be sold well. What are the service needs that we can fulfill…
I understand the motto behind that but I think over confidence is what really driving such conversation. Do I have to remind all here the old rule when you are dealing with a complex industrial problem ? 80% of design = 100% of time&budget. Refining the last 20% can cost you as much time and a tremendous amount of what ever left in your own pockets.
So lowering complexity is not a prudent approach. It’s a design objective! Or to say it less bluntly: it’s the requirement.
I know that many here thinks the Yanks gradual approach to stealth was only a sign of their deficiencies and blablabla… But look for one second… From have blue to the NGB, how many prudent steps were taken by the top of the cream in this industry? And how many are Turkey, India Korea planing to take? One. ONE!
C’mon guys. That path lead to a concrete wall. You’d either have your industry broke, your pilot frightened to take off in teh new stealthy widow maker, the OP perfs be anemic or the planes lightening up like Christmas tree on everyone scope.
So ppl have to be reasonable. A first stealth jet fighter, for some industries that never have really completed a single modern fighter jet, is an achievement by itself. It’s not because of the internet that you don’t have to keep tracks of this fact.
So. WHat all the digression above does told us ?
– Size have to be small
– Number of paneling components have to be kept low
– Number of connected sub-assembly have to be low
– Shape have to be either radical or completely conservatives
– Mission panel have to be restricted to what the user will need IN NUMBER to balance it’s OP tempo
– One single pilot
– No unmanned
– Mach >1.6 + k*F(available tech) : means that you don’t plan to use supernatural stealth composite to balance for a lack of industrial/R&D knowledge. You take what is supposedly available on the market and derived/create your own similar product.
Months ago (years?) I pushed the idea of a wing on top, single panel wing composite skin design. basically, this is where you start: a bad looking supersonic stealthy Cessna.
Regarding the eng, I known that many think that a twin is a modern choice, but may I remind you that this idea surfaced at the time when reliability of engines was not what we know today? That nowadays most twins are no more survivable that a single enginned fighters ? So unless you are planning to go wide spaced (hence the radical shape option), there is only detrimental consequences to go for a twin.
Etc… Etc…
Yes yes. Modular Modular Modular. This is the new trend of the 5-/5+ or 6th Gen. I also firmly believe in that concept since I read the USN paper.
Regarding the point you raise for a twin 125, in my view, there is no diff btw a twin light weight and a single light weight. A Welter is a Welter. I was opposing the heavier design to the lighter.
That article does not say that Korea has decided on a twin-engine design, merely that the Air Force would prefer one. There are different factions with different preferences: ROKAF, DAPA, KAI, ADD, IDA … and of course LM.
…possible move… You’re right. I should have been more precise.
Regarding LM, it’s another story. Or, more adequately said, a singularity in that story 😉
I think this subject desrve its own topic. Here it is: http://forum.keypublishing.com/showthread.php?128948-What-kind-of-5th-Gen-project-for-the-raising-aeronautical-nations-around-the-world
ROKAF back more ambitious twin engine design for KFX program.
So they are favoring a twin heavy design that will cost more, be less stealthy, have less sensor sophistication and be more or less on par dynamically with what the US will have built in a greater number since a decade (at that time) and for less bucks…
Sometime I wonder if all the French Programms leader have all emigrated in Asia. 😀
A very strong Return of Experience from the Chief of Staff of the Fr AF Gen. Denis Mercier regarding the Reaper:
“The problem with the drone is the more we have, the more we need. It’s an essential capability,” he said.
Sad only that Fr took so much time and such a cumbersome path to get there. But here we are now and that’s what is of any importance.
Mmm… LM being rather unopen about the problem: bulkhead cracks found in September 2013.

LOL tht’s even less than what will cost a single A330 MRTT to taxpayers.
And why should you have extra MRTT? Because you’d need to go en force to deal with the IADS without stealth assets.
So, What you shld say on a pure logic basis is that operating more 35 will save money.
Competition would be a disaster. Given that I don’t know a single PLM soft at Industry level that work as advertised… I am very skeptical of launching a 1b$ RFP with armies of greedy commercials jumping on the basket. Better doing so internally, slowly or subcontracted to someone alrdy in the aero industry.
We hve heard here about the numerous bugs, defects and the fact that it is Window based.
However, the planned out of system operation time is one month. With or without bugs 🙂

Advanced F-16 (based on Block 60) could do 3 of the 6 missions and Gripen E could do only 2 out of the 6 missions.
From the last two, F-16 Adv. was slightly favoured over the Gripen E.

Thx for that Flex. Really informative. Even a single slide of a generic *.ppt* would be welcomed 😉
I am still stunned LM or Boeing didn’t go for a Super16/18.
DJC – Leave it to journalists to get it wrong.
So exactly how long can you sustain F-35 operations if ALIS malfunctions for any reason? Can you explain to the class how it operates globally while being air-gapped from any other network?
It’s clearly stated in the documentation: 1 month.
Segmented? Where?
(by the way, it’s old 70’s stuff. Someone had to say it – Sry).
I like the BL fence door with laser pre-cutting and punched/bent holes.
My post went chopped on the forum (Wifi in Mexico – run away from it!). So I deleted it. Sry
Perhaps the fact that the Eagle doesn’t have any LE device like slats or LE flaps makes an increase of AoA during SRT more acute.
Generally speaking, I will tend to think that large platforms are far less sensible to MLU than smaller ones.
So pilot will have to turn their head 180° to see whats behind on their HMS???
Logically they won’t have. User experience alrdy exist in the industry. Augmented reality is neither new to the US tht it is to Fr.
But you know that…
Regarding raw power, you also have to factor the concerns with security (passive, active, re-active) is the nbr 1 priority. I am not sure that this was fully implemented at program launch, but that must have been achieved now and this takes time.
Most of the program can run well on fairly older processor if RAM and coding is appropriate (remember the old Comodore/Amiga models?).
Concern is not on power but the usefulness of that. Very similar with the choice of having or not some canards to play with the AoA 😉
