We’re at the Pratt & Whitney media days today and tomorrow. This is the Technology at PW panel. Participants are:
Alan Epstein, engineer and moderator. (AE)
Michael Winter, chief technologists (MW)
Graham Webb, MRJ, CSeries and EJet engines. (GW)
Jimmy Kenyon, advanced military programs. (JK)
All information is paraphrased.
GW: At $4/gal, over 60% of cost to an airline is for fuel. Engines must cut these costs. A380 and 787 consume less than 3 liters per passenger, about that of a compact car.
GTF is certified [on CSeries]. GTF now on five airframes with 12 sub-types. The engine reduces fuel and maintenance costs, reduced emissions. Fuel savings now demonstrated at 16% less than today’s engines.
Next generation of GTF will further reduce fuel burn by 10%-15%.
MW: The noise footprint will stay predominately within the airport boundaries, using 2,000 fewer foils, about half of our competitor’s engine. Emissions are about 50% below current regulations and working with NASA toward 88% below current levels.
Current bypass ratio about 13:1 and currently testing with NASA 15:1 and 18:1.
375% improvement in efficiency since the days of the Whittle jet engine.
We have the most advanced cooling system in the industry and we are exploring inserting advanced materials into the engines when there is real benefit to the customer.
JK: We’re seen similar trends to improve efficiency in military as with commercial. The Department of Defense is the biggest user of energy in the country, with about 80% in engines.
The military has seen really tight budgets in recent years. There is more than just a cost issue, it’s also an energy security issue (Iraq, Afghanistan challenges). There is a real interest in cutting energy usage and aviation being such a large part, it is a natural place to look.
The strategy considers places where you have to fly farther and/or stay on station longer. We’re working on technology to provide fuel management and efficiency to reduce costs, fly father and stay on station longer.
We’re working with USAF to obtain 25% improvement in fuel efficiency on next engines, and with Navy to also improve efficiency, and leveraging work in the commercial arena to improve thermal efficiency.
AE: Are you a one-trick pony? What have you got besides the gear?
GW: We have advanced fan module, bringing forward light weight fan cases, the next generation combustor, advanced core, state-of-the-art high pressure turbine and high speed low pressure turbine, all of which designed for the very high speeds. There are control system enhancements, working on next gen of the fan-drive gear system, short inlets for enhanced efficiency.

GE analysis post Farnborough
Our wrap up of Farnborough would be incomplete without looking closer at the world’s leading engine supplier, GE Aviation, which together with partners (like SAFRAN in CFM joint venture) garnered more than $36 Billion in orders and commitments during the show. This figure was only significantly bettered by Airbus ($75 Billion) and it came close to Boeing’s $40 Billion. With such level of business the claim by GE Aviation CEO, David Joyce, that the Airbus A330neo engine business was not the right thing for GE as they have more business than then they know what to do with, was certainly no case of “sour grapes”.

Farnborough Air Show, July 16: Orders Summary
Here are the orders we’ve seen for today (there could be more); this should pretty well do it for the show, though it does continue through Friday and there probably will be a few more deals:
Items of interest:
Auxiliary fuel tanks for Bombardier Q400: Marshall Aerospace and Defence Group and Bombardier Aerospace are developing an External Auxiliary Fuel System solution for the Bombardier Q400 turboprop aircraft.The solution, which will be available as an official Bombardier option, will provide up to an additional 10,000lb of fuel in two external pannier tanks allowing the aircraft to fulfill a whole range of missions requiring additional range and endurance, allowing this turboprop platform to be able to sustain operations of up to 12 hours.

Farnborough Air Show preview
The Farnborough Air Show is just around the corner, and we don’t expect the event to be especially newsworthy.
Here are our expectations for the show:
Airbus
Market expectations are that Airbus will launch the A330neo at the air show, and we know John Leahy, COO of Customers, would like to do so at this event. His bosses, Fabrice Bregier and Tom Enders, have been less than encouraging that this announcement could come at the show.
Although news stories last week indicated Airbus’ board may green light the program in advance of the FAS, it was nonetheless reported that a formal public launch may not be made at the show. So what might happen? An “Authority to Offer,” or ATO, might be how Airbus proceeds. We don’t think there will be firm orders ready to go when the FAS begins July 14—although certainly Airbus could also take Boeing’s 777X approach and announce “commitments” as was done at the Dubai Air Show.
We are skeptical whether there might be any A330 Classic orders announced, as customers await the neo. We certainly expect the usual orders for the A320 Family. We expect A350 orders. We’re doubtful of A380 orders.

American easing away from continuous hubbing, returning to peak banking
American Airlines will ease away from the continuous hubbing that smooths operations at key airports, increases aircraft utilization and cuts costs as it returns to the peak-and-valley hub-and-spoke system adopted decades ago under former CEO Robert Crandall.
Although this will mean higher costs and big gaps in airport activity, the increased revenue potential–called the power of the hub under Crandall–will offset the increased costs, says Derek Kerr, CFO of American.
We were at American’s Leadership Council meeting for 1,500 employees yesterday. The meeting itself was off the record but we talked with Kerr afterwards on the record.
Kerr, CFO at US Airways prior to the merger between AA and US, said that the continuous hub can’t connect as many passengers as the traditional hub, leaving revenue on the table. Continuous hubbing allowed a 45 minute ground time, which is too short–an hour is needed to maximize connections.
Re-hubbing will occur this year at Chicago, Miami and Dallas.
Southwest Airlines was a pioneer in continuous hubbing, though it wasn’t called this until perhaps a decade ago. Southwest essentially rolls the airplanes up, deplanes, enplanes and departs. At its origin, long before carry on bags, bag fees, security issues and other factors arose, Southwest “turned” its planes in as little as 10 minutes. Today turns are 30 minutes or longer, in part as planes get larger and carry-on bags slow the enplaning process. Still, Southwest eschews the term hubbing and indeed its connection percentage is far lower than American and other traditional airlines.
The de-hubbing is just one step the US Airways management team is taking to remake American following its emergence from bankruptcy last year and the merger in December.

Airbus Innovation Days, Part 3: the A320neo
Klaus Roewe, SVP of the A320neo Family:
There are 2,700 A320neos in the backlog. Roewe provided a program update during the Airbus Innovation Days. Here is a paraphrased synopsis.

PW Media Day 2: GTF gets 35,000 lb thrust rating
Pratt & Whitney today confirmed that it will offer a Pure Power Geared Turbo Fan engine with 35,000 lbs of thrust, an increase of two thousand pounds from the previously announced model that powers the Airbus A321neo.
Officials declined to confirm our previously reported thrust bump for the Bombardier CSeries GTF, continuing to stick with its prepared statement.
Thrust bumps are largely considered for hot-and-high operations, where the extra boost is needed to get off the runway with maximum payload. In most operations, the extra thrust isn’t needed. The trade for the extra thrust is higher maintenance costs.
Airlines, according to one engineer, tell engine OEMs that they don’t want the extra thrust as the engine is being designed because of the associated extra costs, but then invariably later say they do.
Market Intelligence tells us CFM is going to provide a 35,000 lb model of the LEAP that powers the A321neo and the Boeing 737-9 MAX.
Separately, PW announced:
