Thanks JWCook! So we could see EJ230s perhaps for Tranche 3 Eurofighter Typhoons.

😀

Its possible depending on demand.. but remember with the war setting we already have a Ej230 at the flick of a switch 😀 we just have to wear the maintainence cost.

It doesn’t however say with what load. By the way, are any growth engines in development for the Eurofighter?

The Ej200 has a planned upgrade path

The easy bit is just a 15% improvement on the 20,000lbs design requirement of the original XG-40 demonstrator engine, which ran for 200 hours and achieved over 4,000 cycles of dry and reheat running, operating at temperatures 50 degrees above the Ej200 maximum rating.

Since then the Ej200 has gone through several marks:-
EJ200-DVE in 1988 (test-bed only – various changes throughout life to support development of flight engines)
EJ200-01A in 1995 (first flight standard with C1 DECU)
EJ200-01C in 1997 (modified HP compressor and reduced smoke combustor)
EJ200-03A in 1998 (New all-blisk fan, new digital control C2 DECU and Lean-burn combustor with vaporizers replaced by atomizers),(these were the engines on the Typhoon DA6 aircraft that crashed due to software/engine problems).
EJ200-03B in 1999 (modified LP and HP compressors, and rich-burn combustor with atomizers)
EJ200-03Z in 1999 (“productionised version” – modified HPC and HPT, new OGV and LPT)
EJ200-101 in 2002 IES (Interim Engine Solution) Production engine (new LPT)
EJ200-101 in 2004 FOC Production engine (modified HPC and LPT)”

and so on, each of these gave better performance or easier production, but you will notice that the published thrust figure of 20,000lbs have not changed 😉 .

The Ej200 = ~20,000 lbs thrust, the 15% improved model is supposed to be called the ej230 = ~23,000lbs in ~2010 and there was talk of a possible further upgrade to an Ej270 = 27,000lbs 😮 in ~2015, but this requires large engine modifications

“~” = “somewhere around”

3. EF uses an M-scan radar, which is clearly a technology from the past, even more so than the PESA RBE2.

Nic

Your confusing the front end mechnical system with the entire Captor system, it is a very modern software driven set (with a mechanical front end), The tranche 1 captors processors are obsolete, they had to move to a new processor portable system for tranche 2, in essence to a windows type system which uses a “hardware abstraction layer”, the original algorythms are ported with software wrappers, This ability means intergration of an E Scan radar is not only technically possible and easy, but financially benificial too, due to reliability increases during its lifetime.

It also means there not tied too closely to one set of processors (take a look how is the F-22 is doing :rolleyes: in this regard)

With only the radar array, a couple of LRU to replace and plumbing in additional cooling, it should only take ~5 hours as stated before.

BTW anyone know if there going to solve the E Scan disadvantage by putting the Captor E scan face on a gimbal?

Gives an overview of how the move to new processors is being done.

EH101 renamed the US101

Ok, call me an ignorant American, but :confused:

Matt

Its cockney ryming slang ie
Bristol city = titties
Septic Tank = Yank

You generally only use the first words ie “Look at the bristols on that septic!”

😉

Cheers

I really hope its not just a rumour!,I would like to see an export Rafale!.

Hope they release details of the evaluation process too.

Cheers
