Le LeapX enfin sur les rails...
Il semble que oui ! Une reconsidération du diamètre du fan, en dernière minute, leur à sauvé la mise !
Dilution 10 maintenant !
Avant, c'était -1% vs le GTF, maintenant ce serait + 1 % (C'est Tom Brisken qui le dit )Une situation qui tournait à la cata, juste redressée, il y a un mois seulement !
En tout cas retour vers un plus grand équilibre pour le Bourget, ils ont le moral chez CFMI !

CFM International will announce a raft of orders for the Leap engine
on the A320NEO (new engine option) at the Paris air show following a
late redesign with a larger fan, which makes the engine more competitive
with Pratt & Whitney’s PW1100G geared turbofan.
Over the course of the show, CFM will reveal additional
members to the initial Leap customer group, which is expected to include
International Lease Finance Corp. (ILFC), Gecas (General Electric
Capital Aviation Services), TAM of Brazil and Malaysian low-cost carrier
AirAsia. Virgin America, which confirmed its selection on June 15,
also chose Leap after CFM grew its fan diameter by 2 in.
In all, the initial sales surge is likely to include
engines for up to 350 aircraft. The bulk of these are destined for
AirAsia, which is reported to have recently upped its order to 200 from
150, while Gecas is expected to announce orders for 40-60. TAM, which
earlier this year signed a memorandum of understanding for 22 A320NEOs,
is also poised to select the Leap engine. A further 40 aircraft are on
order for ILFC and 30 for Virgin America.
The PW1100G is already launched on the A320NEO following
firm commitments from Lufthansa, ILFC and India’s IndiGo, while the
first Leap version is already committed to development for the Comac
C919. Both engines are also officially in the frame for possible use on a
re-engined Boeing 737. To date, Pratt has announced agreements to power
240 of the 332 A320NEO aircraft confirmed so far, although these
numbers are due to change as Airbus has targeted orders and commitments
for 500 or more NEOs by the Paris air show.
“We’ve recently optimized the product and gone to a
little larger fan diameter,” says Tom Brisken, CFM’s general manager for
commercial customer strategy. “In the beginning, Airbus was not giving
us a good score, and we heard that from customers. We were extremely
upset, but now we’ve got the same boundary as Pratt & Whitney. The
result is, we have increased the fan diameter by 2 in. without impacting
ground clearance, and we’ve increased the bypass ratio to 10:1.”
Exactly why CFM appears to have been constrained to a
smaller fan for so long remains a mystery; but following the change to a
78-in. fan, Brisken says, “I think Airbus will rate us equal in fuel
burn, although we think we’re 1% better, so we’re going to have a 1%
advantage—and that’s the story we’re going to be telling customers.
Before we were discussing an engine with a 76-in. fan, and over the last
month we’ve been able to market the engine on a much more competitive
position. Before that, we were having issues in our campaigns,” he
