Pontifications: Moonshot for engines for Next Boeing Airplane may have to wait

By Scott Hamilton

Sept. 12, 2023, © Leeham News: The Next Boeing Airplane (NBA) may be a moonshot for CEO David Calhoun, but airlines will probably be reluctant to take a moonshot on the next new engine.

Service issues with the CFM LEAP and Pratt & Whitney GTF engines are driving airlines batty. The failures of the Rolls-Royce Trent 1000 years after entry-into-service (EIS) cost RR hundreds and millions of dollars and a confidence crisis that hurt future sales. LEAP engines are coming off wing well before initial forecasts. Every aircraft model using the GTF faced groundings as engine failures piled up.

Boeing sorely needs a successor to the 737, now in its 55th year and fourth iteration. Ron Epstein, the aerospace analyst for Bank of America, was biting in a Sept. 7 research note.

Flying a Boeing 737 is like driving a ‘68 Chevy Impala with a semi-modern dash.

 “We note that Boeing continues to ride on the coattails of its past glory. The original Boeing 737 prototype first flew in April 1967, entering service less than a year later in February 1968 with Lufthansa. Fifty-five years later, the 737 airframe remains in service through a multitude of derivative models, including the most recent 737 MAX,” he wrote.

“However, we note that the model was never intended to be such a blockbuster long-term solution. Instead, the 737 was expected to be a band-aid for the Boeing portfolio to compete with the market share-winning DC-9. The Boeing fleet lacked a smaller narrowbody model to complement the company’s larger jets, like the 707. In the spirit of the General Motors model, the 737 was intended to be the ‘cheap Chevy’ of the portfolio. Fledgling carriers would operate the cheaper model before upgrading to Boeing’s large, higher-end products like the 707 and, later, the 747, which one could see as the ‘Cadillacs’ of the portfolio.

“In our view, while the longevity of the 737 is impressive, the aircraft is now a bit of an anachronism. Operating the aircraft is like driving around in a 1968 Chevy Impala with a semi-modern dashboard. It is important to note that the 737 is the only currently manufactured commercial aircraft without fly-by-wire controls, which are a staple in modern aircraft control system design.”

Epstein worked for Boeing from 1995 to 1999 as an Applied Research Scientist. He’s a technical advisor to United Airlines for the alternative energy sector.

United selects GEnx for order for 100 787s

Aug. 14, 2023, © Leeham News: United Airlines quietly selected GE engines for its order in December last year for 100 Boeing 787-9s, according to Boeing’s website. The order isn’t finalized and neither GE nor United would comment.

There had been speculation that UAL might order Rolls-Royce engines as a mitigation for cancelling 45 Airbus A350-900s, which is powered exclusively by RR. United repeatedly deferred delivery of the A350s, which were ordered by previous managements. United inherited a large order for 787s when it merged with Continental Airlines and placed repeat orders for the 787 after the merger. The A350s essentially are duplicative to the 787s.

United placed large orders for the Airbus A321neo at a time when Boeing at first dithered whether to launch the New Midmarket Aircraft. UAL added to the neo order during the time when Boeing was unable to pursue any new airplane program due to the extended grounding of the MAX and during the COVID pandemic.

Pontifications: Engine makers’ business model needs overhaul

By Scott Hamilton

May 2, 2023, © Leeham News: The business models for engine makers for decades have been simple: deeply, deeply discount the engines on the sale and make up the revenue and profits on the maintenance, overhaul, and repair (MRO) contracts.

It’s a model that’s served engine makers and customers alike well. Customers save millions of dollars on the upfront purchase of airplanes. The engine companies win market share.

There are downsides for the Original Equipment Manufacturers (OEMs), though. The discounts typically are steeper than those offered by Airbus and Boeing (and Embraer and ATR). LNA has seen deals with discounts as steep as 80% on the sales price. We’ve even seen one deal in which the OEM gave (as in free) the engines in exchange for the MRO contract.

The big downside to this is that it can take 10-12 years, or more, for the OEMs to recover their research and development and production ramp/learning curve costs. Then as the CFM 56 matured into perhaps the most reliable jet engine ever, with more than 25,000 hours on-wing, followed by the IAE V2500, MRO services contracts didn’t return the revenue and profits as quickly as before.

Pontifications: One “good” engine in future for RR, faulty business strategy and model: JP Morgan

By Scott Hamilton

Feb. 7, 2023, © Leeham News: Our report last week about Rolls-Royce’s new CEO characterizing the company in dire straits is just part of the story. Shortly before that, on January 18, JP Morgan issued a 38-page dissection of the company that perfectly encapsulates what LNA has pointed out in the past about its commercial engine business.

Pontifications: New Rolls-Royce CEO paints a dire picture; all scenarios on table at Airbus

By Scott Hamilton

Jan. 31, 2023, © Leeham News: Rolls-Royce’s new CEO says the engine group is a “burning platform,” failing to give returns.

Tufan Erginbilgic, who joined RR as CEO on Jan. 1, said this is the “last chance” to get its house in order and turn a profit.

The dire outlook has potentially disastrous implications for Airbus. The airframer relies exclusively on Rolls for its engines for the A350 and A330neo. Airbus is monitoring the situation closely. Market sources tell LNA that Airbus is assuring customers and potential customers that Airbus will make sure engines and aftermarket support are available, without detailing how.

An Airbus insider tells LNA that all scenarios are under consideration. Some speculate that Airbus might either provide financial support to Rolls or even, in the extreme, buy the engine company. Others believe either course is unlikely because Airbus has its own production problems to sort out. Its fiduciary duty is to its stockholders. “It’s not their job to inherit a problem that was created decades ago,” one London-based analyst says.

What’s at the root of RR’s current problems? Many of the reasons have been discussed before, but let’s summarize them.

Pontifications: A lost decade for new airplanes

By Scott Hamilton

Dec. 5, 2022, © Leeham News: In September 2020, LNA wrote that commercial aviation was facing a “lost decade.”

The impetus for this prediction was the COVID-19 pandemic crisis.

“Commercial aviation is facing a lost decade due to COVID,” we wrote. “Yes, most forecasts target 2024-2025 as returning to 2019 passenger traffic and aircraft production levels. However, LNA in July published its own analysis indicating full recovery may not occur until 2028.”

Nobody predicted that effective vaccines would emerge as quickly as they did. Drug makers in the US and Europe moved heaven and earth to produce vaccines to fight COVID-19. These have been, by and large, extremely effective. (I’ve had two shots and three boosters and have not caught COVID, despite being at one major conference with 13,000 people.)

China created its own vaccine, which failed to stem the tide there. President Xi quickly adopted total lockdowns at the first sign of outbreaks. Despite this, China is now setting records for new infections. Commercial aviation recovery there remains underperforming. China’s performance illustrates the underlying reasoning we had in concluding commercial aviation was facing a lost decade.

This sector still faces a lost decade, though for some fundamentally different reasons.

Introduction

October 20, 2022, © Leeham News: We finish our series about engine development by looking at the next-generation engines and future trends in airliner engine development.

We limit this look forward to engines that burn Jet fuel (Jet-A1 or SAF) as green propulsion solutions are a vast field and justify their own series. We will pick this up at a future date.

Summary
  • The major reduction in fuel consumption and, thus, CO2 emissions will come from new engines.
  • The technologies to drive fuel consumption down a further 15% are there.
