There has been a great deal of debate over whether Boeing can meet the SFC reduction targets for its 737 MAX. This debate revolves in part because neither Boeing or CFM have been forthcoming about details how the CFM LEAP engine is being optimized for MAX.
We’ve obtained some details to explain how CFM is proceeding.
Details are still sketchy and hard to come by. But our source has direct knowledge of the program.
Our source compared the requirement to reduce the fan size of the 737 LEAP from 78 inches on the Airbus A320 neo to 68 1/2 inches on the MAX to the fan reduction on the GEnx from the 787 to the 747-8. The 747-8 engines are optimized for this aircraft despite the smaller fan size.
Reducing the fan enables CFM to eliminate some LPT stages, our source explains, which also cuts other parts.
This eliminations allow the LEAP to be shorter, which also allows the engine mounting to be shorter.
CFM is also using ceramics to the MAX LEAP.
These are some of the key ways CFM is optimizing LEAP for MAX.
Politicians in Kansas have asked for a review on national security grounds of the Boeing decision to close its defense operations in Wichita, according to this news report.
This is just silly.
Boeing has plenty of security clearances and secure facilities in Puget Sound, San Antonio and Oklahoma City, where the Wichita work is going.
This is a desperate move by Kansas. The Secretary of the Air Force should reject this effort as a complete waste of everybody’s time.
737 MAX: We did this story last week on the development cost of the Boeing 737 MAX.
A330: Airbus is going to boost the range of the A330 to make it more closely match that of the Boeing 777 and 787, according to this story.
Fill ‘er up: Here’s a scary story about a goof in aerial refueling of a Boeing 707-based JSTARS.
In a surprise, Norwegian Air Shuttle split a large order between Airbus and Boeing for A320 and 737 families. The Airbus order is only for the NEO and 737 order is a mix of MAX and NGs.
We expected only the 737 order; we had previously reported NAS was one of the “commitments” for the MAX.
This represents the third all-Boeing customer Airbus has won for its NEO.
NEO deliveries will begin in 2016, equipped with the PW GTF. Engine selection for later deliveries remains open. The GTF enters service on NEO in 2015 and the NEO CFM Leap engine enters service a year later.
Boeing reported its earnings for 2011 and its estimates for 2012, including delivery estimates for the 787–which were surprisingly low.
Boeing forecast 70-85 787/747 deliveries this year, with half (35-44) being 787s. This is will below Wall Street consensus, though David Strauss at UBS predicted 40. We find this a stunningly low number that doesn’t reflect well on either production ramp up or fixing the rework necessary for the more than three dozen 787s at Everett.
Boeing’s own Z24 production plan for this year had a production rate of 45 787s.
We are, as the Brits say, gobsmacked by this information. (Update, 0800 PST: In Q&A, McNerney says 787 deliveries affected by large number of change incorporation required.)
From the conference call:
There has been an active discussion in the comment section on the “Rate 35” post and the relative merits of appraisals and appraisers with respect to the Airbus A320 and Boeing 737NG.
We’ve been involved in the airline business since 1979 and from 1990, when we co-owned Commercial Aviation Report (CAR), have followed the appraisal business. Given the discussion in “comments,” we think a dedicated post is worthwhile.
CAR created the industry’s first commercial appraisal conference in 1990. ISTAT–the International Society of Transport Aircraft Traders–at that time was still largely a small, professional organization, far difference than what it is today.
CAR’s first conference brought together nearly every appraisal company then in existence in the US to compare and discuss appraisals of what was called Enhanced Equipment Trust Certificates (EETCs) and appraisals published by the firms.
Mike Mecham of Aviation Week has a thorough analysis of what’s behind the decision to close Boeing Wichita.
Contrast Mike’s story with this ridiculous analysis. It’s very, very rare that we call out someone else but this one is so far off the wall that we can’t help ourselves. (It should be noted Loren Thompson was paid by Boeing to do a report about the Airbus subsidies and the tanker competition.)
