I don’t understand the debate also:confused: To check or demonstrate something in the industry is not ony wishfull thinking but real testing…
They must have pushed the M88 ECO at 9t on a banch and follow the parameters and concluded it was fine…

In fact it shouldn’t have costed a lot since they only had to take one or some of the M88-ECO test engines available and push them at 9 t….

But if that was the case, why not produce this version?
The Rafale, is currently underpowered and could use all the extra thrust it could get! I dont think it is so simple.

EDIT
What they clearly say is that they CAN produce a 9t M88, but WONT.
Probably the cost will go sky-hi, or they need 2-5 more years for development, or some technology import from the other side of the Atlantic, or bypass ratio might increase or all the above.

arthuro.
You shouldn’t write these things in this thread!!

Certain member might get a stroke:dev2:

M88 engine highlights
(March 2008)

…….

The M88 ECO program satisfied all of its initial objectives, spanning increased engine part life, lower cost of ownership (including reduced operating costs) and higher performance (4,000 total accumulated cycles/TAC). The test engines logged more than 150 hours of flight tests, and the equivalent of 1,800 hours of flight under Rafale mission conditions.
This program also checked out the feasibility of increasing M88 engine thrust to about 20,000 lb.

Now in plain english, directly from the makers.

The F-35 is becoming the F-104 of the 21rst century.

If my calculations are correct and the assumption that M88-3 would come from increasing LP compressor diameter, then bypass ration of th M88-3 should be about : 0,65.

This figure might prove too high for supercruising.

The M-88-3 has a greater bybass ratio, that is only possible with a smaller core engine (it wouldn’t be a very good idea) or change the fan diameter. Therfore increase the fan diameter and use the same core engine (a quick and dirty solution).

Precisely!

And that might explain why AdlA rejected the M88-3.

You constitute an insult to this forum, thus, I have chosen not to answer to your posts.

Thank you for your understanding.

Big news for dassault !

Nice.
How many parisian newspapers will both of them hold? :diablo::diablo:
