PW Media Day 1: next gen GTF to cut fuel costs 10%-15% over today’s GTF

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.

Airbus, Boeing face pricing pressure

Airbus and Boeing face pricing squeezes that are the result of their continuing price wars and two products that need price cuts to maintain sales.

The fierce single-aisle battle between Airbus and Boeing, and to a much lesser extent, between Airbus and Bombardier, puts pricing pressure on the A320ceo and to some degree the A320neo.

Airbus and Boeing each blame the other for a price war that has put pressure on margins for the in-production airplanes, but market share battles are only part of the issue. There is the need to keep the production lines humming for these airplanes in advance of the transition to the re-engined A320neo and 737 MAX, particularly as the Big Two up production rates over the next few years.

CSeries FTV 4 to launch this month with PW GTF testing focus

Bombardier’s CSeries flight testing has now passed the 250 hour flight mark, with three Fight Test Vehicles (FTVs) in the program. FTV 4 is due to become airborne in May. This will be a milestone for the program because this is the airplane that will focus on the performance of the Pratt & Whitney P1000G Pure Power engine that is so integral to the development of Bombardier’s leap into the mainline jet business.

When BBD first proposed aircraft in the 110-130 seat sector, the C110 and C130, in 2004, this was “just another airplane:” little new in the way of airframe technology and using engines then in production. Withdrawn from the market after little interest, BBD revised the airplane into the CS100 and CS300, using an aluminum lithium fuselage and PW’s new Geared Turbo Fan engine.

The GTF promises around 15%-16% fuel consumption reduction and a dramatic decrease in noise footprints. While BBD has gained knowledge of how the GTF is performing from the first three FTVs, No. 4 will be the one that will prove whether all the engineering projections for the engines are correct and whether the engine/airframe combination will meet BBD’s promises of fuel efficiency.

Bombardier also hopes that meeting these representations will get a few customers that have been in the “show me” column to become believers. Disappointed with three program delays that have moved entry-into-service back to the second half of next year, potential customers need some solid results.

The stakes couldn’t be higher for BBD. The CSeries promises quieter operations at especially noise-sensitive airports, including Billy Bishop Airport in BBD’s own backyard in Toronto. Porter Airlines has a conditional order for up to 30 CS100s for use at this downtown airport, and the promised quiet operation is key to government approval to allow commercial jet operations there. This isn’t the only noise-sensitive airport.

Bombardier promotes its CSeries as being more economical than the competing Airbus A319neo and Boeing 737-7 MAX, and our analysis concurs. Sales figures also support BBD: the CS300 has far outsold the A319neo and 737-7.

For Pratt & Whitney, this is the beginning of the end of more than 25 years of research and development of the Geared Turbo Fan, a multi-billion dollar bet to return to the commercial airline engine market it once dominated but lost to rival CFM International when the latter won exclusive rights to power what is now referred to as the Boeing 737 Classic, rights that continue through the 737 MAX.

PW’s bet to return paid off. More than 5,000 GTFs have been sold on the CSeries, the Mitsubishi MRJ and Embraer E-Jet E2, on all of which it is the exclusive power plant; and it has evenly split the market on the A320neo family, on which it competes with CFM and its LEAP engine.

The industry keenly awaits flight test results from BBD’s FTV 4.

OEMs are ramping up services as profit centers

Original Equipment Manufacturers are ramping up their focus on services to increase these as profit centers for company financial performance.

The news April 10 that Boeing will relocate its Commercial Aviation Services unit from Seattle to its fading facility in Long Beach (CA) is another example. After-market support services for all DC- and MD- models and the out-of-production 7 Series airplanes previously were relocated to Southern California. Now, support for the in-production 7 Series (except the 787), the 737-based P-8A Poseidon and the forthcoming KC-46A will shift to SoCal. The 787, 737 MAX and forthcoming 777X support will be in Seattle.

GE engines faces challenge from PW, RR GTF technology

The recent announcement by Rolls-Royce that their future engines will contain gearboxes has put GE and its CFM partner SAFRAN under considerable pressure.

GE/SAFRAN were together with Rolls-Royce proponents to go directly from Direct-Drive turbofans to Open Rotor designs for the next generation aircrafts. This left Pratt & Whitney as the only major engine manufacturer promoting high by-pass ratio geared turbofans as a better alternative for these aircrafts. With the Rolls-Royce announcement of Advance for 2020 (Carbon fanned tri-shaft) and Ultrafan (Geared big fan) for 2025, this has all changed. Suddenly Pratt & Whitney has strong support in their strategy and GE/SAFRAN stand out as loners.
By honing key technologies in their traditional two shaft turbofans GE, and GE/SAFRAN in CFM, have built a market leading position in all thrust classes, Regional (CF34), Single Aisle (CFM56) and Dual Aisle (CF6, GEnx, GE90). Their declared next step was Open Rotor for future Single Aisle while keeping Direct-Drive for larger engines.

Airbus and Snecma continue to research open rotor technology. Aviation Week has this story.
Now this solid position is threatened. The geared architecture has won the future regional market (CSeries, MRJ, E-Jet E2 goes PW GTF), market parity on the A320neo family and the 757 replacement studies by Boeing (dubbed NAS, New Airplane Study) will not go Open Rotor as Open Rotor only works up to M 0.75 and the 757 replacement will likely fly over 4,000nm, necessitating higher cruise speed. The NAS will thereby favor a geared turbofan instead of Open Rotor. Why not Direct-Drive? There are two major reasons:

  •  A geared design allows higher by-pass ratios and thereby higher propulsive efficiency without the engine being too heavy from its large low pressure turbine needed to drive a high BPR fan.
  • A geared design can allow the big fan to rotate slowly and with a low pressure ratio. This creates a low noise engine, a very important feature for aircrafts operating out of noise troubled airports.

GE/SAFRAN has shown with their CFM LEAP project that they can match the efficiency levels of a geared engine like Pratt & Whitney’s GTF, using its superior hot section technology to achieve the high efficiency. It cannot achieve the low noise levels of a geared fan however; engine noise stands in direct relation to fan rotational speed and pressure ratio.
It will thereby be the environmental factors that will put the most stress on GE/SAFRAN’s present strategy. Having lost the regionals to the geared camp, will it also lose the next generation short/medium haul? It will be interesting to watch the GE/SAFRAN over the next 18 months: does it change strategy or not? If one goes by the recent words of GE Aviation President David Joyce (who spoke at last week’s opening of their Indiana LEAP factory), he thinks his present line-up is fine for a 757 replacement, and he sees no urgent need for new developments.

Rolls-Royce plans for new single-aisle, twin-aisle airplane engines

Rolls-Royce may not be at a cross road but it’s certainly at a fork in the road.

RR sought to be a dual-source supplier for the Boeing 777X, competing with GE Aviation for the privilege; it was generally a given that GE would be a provider. The question was whether it would be the sole supplier or share the platform with another. Pratt & Whitney withdrew, concluding the business case wasn’t there for its proposed big Geared Turbo Fan. RR stayed in the competition, assured by Boeing that it wasn’t a stalking horse to GE.

But GE won the position as exclusive supplier, much to RR’s consternation.

Next, the future of the Airbus A350-800, powered exclusively by RR, is in serious doubt. The backlog is now down to a mere 46 as customer after customer, encouraged by Airbus, up-gauged to the A350-900 and -1000 sub-types. While RR is also the exclusive supplier on each of these models, and the engines are largely common, there has been substantial investment by Rolls on the -800’s application. If the -800 is canceled (as many industry observers believe it will be), RR’s investment is largely down the drain. How does Airbus “make good” to RR for this?

Odds and Ends: Airbus neos; 757RS/A320RS; charity efforts

Airbus neos: The conversation continues, with Tom Williams, EVP of programmes, giving an interview to Flight Global about the A330neo and the A380neo. Plane Talking has another version of the Williams interview. Notable in Plane Talking’s report is the indication Williams said it will be a year before a decision is made on the A330neo. Our information is that a decision, whether yes or no, is due this year. PT also reports Williams indicated an A380neo would be a 2020s product. This suggests the prospect of a new engine from Rolls-Royce, which is under development, or conceivably a Big Engine Pratt & Whitney GTF could be considered.

757RS/A320RS: Aerotubropower, whose expertise is engines, discusses the implications of the planned improvements in fuel burn on the Pratt & Whitney Geared Turbo Fan and what this means for the replacement of the Boeing 757, 737 and Airbus A320 families.

Charity efforts: IAM 751, the touch-labor union for Boeing, is often portrayed as a bunch greedy members who feel a sense of entitlement. One can certainly debate this point, but what isn’t debatable is 751’s efforts at charity throughout the year. Every once in a while, we pop over to 751’s blog. Today (Feb. 19) the first four items are about philanthropic efforts in Pierce and King counties.

Just as 751 members are often cast as greedy, so is Boeing, so it is only proper in this context to point out that Boeing also engages in philanthropic endeavors throughout the US (we don’t know about abroad). Here’s a link to some of Boeing’s efforts.

Odds and Ends: LEAP vs GTF; CSeries flight testing; MRJ FAL

LEAP vs GTF: Reuters has a story looking at the intense competition between CFM and Pratt & Whitney for the market dominance of the LEAP vs Geared Turbo Fan engines.

The only airplane where there is competition is on the Airbus A320neo family; CFM is exclusive on the Boeing 737 MAX and COMAC C919 and PW is exclusive on the Bombardier CSeries, Embraer E-Jet E2 and Mitsubishi MRJ. PW shares the platform of the Irkut MC-21 with a Russian engine. PW says it has sold more than 5,000 GTFs across the platforms. CFM has sold more than 6,000 across the three models it powers.

On the A320neo family, the competition is 50-50 at this point, with a large number of customers yet to decide on an engine choice. However, 60 A320neos (120 engines) ordered by lessor GECAS never were in contested (GECAS buys exclusively from CFM) and 80 A319/320neos from Republic Airways Holdings (160 engines) were part of a financial rescue package for then-ailing Frontier Airlines.

PW’s joint venture partner, International Aero Engines, shares the A320ceo family platform with CFM. Late to the market, IAE caught up to CFM in recent years.

On platforms where they compete, the sales figures so far show a neck-and-neck competition between CFM and PW.

Update, 12:30: The link has been fixed. Update, 9:30 am PST: Flight Global has this story reporting that PW plans a Performance Improvement Package on the GTF that will further cut fuel consumption by 3%.

CSeries flight testing: Bombardier’s CSeries flight testing has been slow to this point, but it’s beginning to ramp up. Aviation Week reports that FTV 3 should be in the air by the end of this month and FTV 4 should follow in April. FTV 3 is the avionics airplane and FTV 4 focuses on GTF engine testing.

Mitsubishi MRJ: Aviation Week also reports that the Mitsubishi MRJ airplane #1 is nearing final assembly.

Outsourcing focus of Boeing report, but misses bigger picture; IAM vote aftermath; Boeing’s 2013

A long article (10 pages when printed) discusses the pitfalls Boeing had by outsourcing so much work on the 787. This much is not new. The point the article raises–transferring technology and the potential decline of US aerospace dominance–isn’t especially new, either; we’ve written about this in the past.

What the article, however, overlooks is that Boeing isn’t alone in doing this. To certain degrees, Airbus, Bombardier and Embraer also are guilty–as are a number of other OEMs and suppliers. CFM International, for example entered into a joint venture with the Chinese that would help them develop an modern commercial jet engine. Fortunately, CFM pulled back on this over concerns of technology transfer.

Airbus has an A320 assembly line in Tianjin, China, and Embraer had an ERJ-145 assembly line in the PRC. McDonnell Douglas had an MD-80/MD-90 line in Shanghai.

Bombardier contracts with Chinese companies to produce the Q400 and CSeries fuselages, the latter with the advanced aluminum-lithium metals.

The airframe OEMs will tell you that final assembly represents a small portion of the airplane and the risk of technology transfer is minimal. But it’s probably no coincidence that the COMAC/AVIC ARJ21 looks the the MD-80 (but sized like the DC-9-10) or that the C919 looks an awfully lot like the A320.

The article points out that Mitsubishi, which builds the wings for the Boeing 787, is now using this experience to design and build the MRJ-90. True enough, though it should be noted that having experience the composite wing issues associated with the 787, Mitsubishi abandoned plans for a composite wing for the MRJ and is proceeding with metal instead.

Suppliers are basically extorted by China: if you want to sell us your goods, you have to be prepared to transfer technology. Suppliers can’t ignore this huge market, but try to mitigate the blackmail by transferring “yesterday’s” technology or at least developing tomorrow’s technology today while transferring today’s technology to China.

It doesn’t stop with China, of course. Boeing and Airbus have Russian ties with engineers. Bombardier is planning a Q400 assembly line in Russia. Indian engineers work on Airbus and Boeing airplanes and now plan their own turbo-prop.

The days of the Big Two Duopoly are numbered. And it’s not just Boeing that is guilty of aiding and abetting the new competition.

Boeing’s Good Year in 2013

Set aside the disruptive and embarrassing ground of the 787 in January through April, Boeing had a very good year in 2013. It posted a record rate of deliveries, besting Airbus for the second year in a row. It’s order book was the best since 9/11. Here is the press release.

Airbus announces its 2013 production and delivery results on January 13.

Boeing-IAM vote: After-thoughts

We can’t go by this week without a short commentary on the Boeing-IAM vote on Friday, but we’re not going to spend a lot of time on this—we’ve analyzed this issue a number of times and there is little more to say except this:

It was a very tough vote for the union members of IAM 751. Giving up benefits won in previous hard-fought battles is always tough. But the Boeing 777X will be assembled in Washington State, and the composite wings will be built in Washington, too. Our view is that having 80% of something (benefits) is better than 100% of nothing (the 777X).

Boeing, of course, will return to the State and the union for more tax breaks and concessions when the 757 and 737 replacements are designed and a decision is needed about where to build these airplanes. Boeing is now in a position to seem more concessions from labor during a contract that’s in place to September 2024, and the union can’t strike. It’s been significantly weakened, losing leverage ion addition to benefits as a result of Friday’s contract vote.

But this enables Boeing to tell customers the threat of delivery disruptions from strikes is gone, and this will reassure them, which may or may not help sales—thus providing more work for IAM members.

Boeing faces a huge morale problem for the members who feel they’ve been had in this process. IAM members have long, long memories. Although there is no option to strike, members can “work to the rules” or find other ways to decrease productivity. Boeing has some real fence-mending to do. We’ll see whether it makes any effort to do so.

Labor isn’t content with the narrow yes vote, however. Some are calling for a third vote, arguing the January 3 election date was set to deliberately disenfranchise a large number of union members who likely would have voted No. Turnout last week was lower than the November 13 vote because many members were still on vacation from the Christmas and New Year’s holidays.

Airbus, engine OEMs make the case for A340 future

Airbus held a summit December 4 for stakeholders in the A340 to explain how there continues to be life after production ended and despite being a four-engined airplane in a two-engine world.

Key to the future of this out-of-production airliner is increasing the capacity of the A340-600 to an exit-limited 475 seats and for Rolls-Royce to alter its Total Care engine maintenance Power-by-the-Hour terms and conditions to reduce costs.

Airlines, financiers, appraisers and the engine makers were invited by John Leahy, chief operating officer-Customers of Airbus. Engine providers CFM International, Rolls-Royce, Lufthansa Airlines and Hi Fly, a small European airline, made presentations in addition to Airbus.

Airbus produced 246 A340-200/300s and 131 A340-500/600s; 227 and 131 respectively are in operation or parked.
