ok, poor phrasing on my part, change
lack of money and allocation to other uses seems more believable
to
prioritising the budget allocation to other uses

TMor if you are happy to say that the blog writer only backs up your opinion, thats fair enough and not claim it as proof of life, a definitive fact
rand does make the odd mistake that they retract but are generally creditable

i feel generally quoting blogs as fact will lead us down the garden path to the fairies

always happy to help you have a better understanding arthuro

as i said it sounds like sour grapes from thales

http://www.rand.org/pubs/documented_briefings/DB358/DB358.part2b.pdf
BAE Systems also has teamed with Dassault Electronique to develop the towed decoy for the Mirage 2000 and Dassault Rafale

do you have a link to the thales statement, i’d like to read it

Trident
a towed array isnt really comparable, it sounds similar to the mald-j stand-in jammer

its a blog post from someone that doesnt know that cooperative jamming and decoy dispensing is used on the f-16.18.35.22 that i know of and probably the f-15 too

GaN is the next step, raytheon has been developing it for years and just done a proving 1000hr continuous test for use with AESLA, an Active Electronically Scanned Lens Array radar [focused aesa] for service in 2014+ depending on gov funding
More specifically, AESLA employs high-power transmit-receive radar modules, enabled by gallium nitride (GaN) monolithic microwave integrated circuits (MMICs) that pack more power and performance than conventional silicon-based electronics. The other important technology is a low-loss, reliable phase shifter employing radio frequency (RF) micro-electro-mechanical systems (MEMS) technology. MEMS combines computational abilities with the perception and control capabilities of microsensors and microactuators, creating smart machines at a cost comparable to integrated circuits.

Raytheon believes they can get 10x-100x the performance of existing radars with this approach, while remaining at the low point of the cost curve.

Raytheon’s gallium nitride chips meet operational milestone

Gallium nitride (GaN) chips from Raytheon in Tewksbury, Mass., achieved 1,000 hours of reliable operation, moving the technology closer as a standard for next-generation radar. Raytheon engineers have demonstrated the operation of a GaN power amplifier microwave monolithic integrated circuit (MMIC) operating for more than 1,000 hours with no measurable performance degradation. GaN technology provides increased reliability and efficiency, resulting in lower prime power consumption and relaxed cooling requirements, Raytheon officials say. GaN T/R modules provide higher long-pulse radio-frequency (RF) power than that of standard gallium arsenide (GaAs) T/R modules, company officials say. “This milestone enables us to insert GaN next-generation capability into a multitude of air and missile defense programs,”

most of that i agree with loke
except that its come 2012-14 with the upgrades, then i’ll agree that the rafale is an excellent 4.5 gen fighter
it would have been better if it could have been done earlier
but heck, us aussies havent designed and built even a trainer recently, the last plane we did was just after ww2

If you notice on the F119 cartoon posted above, the hardware aft of the second stage turbine (flow mixing and augmentor stuff) is missing. That was done due to its security classification. The F135 uses nearly identical technology, but the F135 cartoon substitutes F100 hardware in that location for disinformation purposes. :diablo:

thanks, i didnt know that
blue has trouble understanding what he reads, it seems he also has trouble looking at pictures
the bypass air serves to cool the engine core as it passes around it and then the long mixing chamber on both the f135 and f119
it doesnt run the whole length of the engine to exhaust and mix as it leaves the plane
do you agree ?

jackjack :
No . The F119 ‘s cool air bypassing chamber surrounds the whole length of the engine , the F135 doesn ‘t exhibit the same design . Then , the F119 ‘s nozzle is made to mix the cool air with the hot gases from the exhaust .
Look carefully at the drawings :

F119 :

F135 :

Cheers .

“”The F119 ‘s cool air bypassing chamber surrounds the whole length of the engine””
no it doesnt seem to, look closely at the f119 and f135 again
gee, why is this so hard for you

look at your picture, the cool air inlet is the same position after the central exhaust duct, only the f136/f119 has a long mixing chamber, why that is isnt generally known and i cant say

this is bluewings previously posted picture, note the central exhaust duct position and then look at the f119 and f135 again

i actually meant as an aftermarket sale of EW systems to non french planes (eg israel sales of ew systems)
icms were sold with the mirage, werent they ?

there was a topic on here about the ICMS

A very predictable response! It was clear that you would argue for the Rafale, but lack any details about the other aircraft. You make the claim, it’s up to you to back it up, not others to wrong prove your claims, you can’t prove in the first place.

Scorpion :

Excuse me Scorpion but when I asked if the F135 engine was featuring a “cool air bypassing chamber” , I already knew the answer : no .
only the F-119-PW-100 and the M88-2 feature such air cooling system to dilute the hot gas .

The F135 engine :
http://www.pw.utc.com/Products/Military/F135

your ability to show what you don’t know never ceases to amaze me
the f-35’s f136 is an evolution of the f-22’s f119 and yes it does have an air cooling system
if you read up you will find the f-35 has even better cooling tech than this though

http://www.f135engine.com/proven-tech/common-core.shtml
The F135 improves upon the validated f-22’s F119 core, integrating the F119’s high-performance six-stage compressor and single-stage turbine unit with a new low-pressure spool. Together the F135 and F119 will have logged more than 600,000 flight hours before the F-35’s introduction into operational service in 2012.
