Pontifications: Two sentences described Boeing’s last two years
By Scott Hamilton
Oct. 24, 2022, © Leeham News: The question to Boeing CEO David Calhoun was put in levity. His response was telling.
Susanne Clark, the president of the US Chamber of Commerce, noted before last month’s Aerospace Summit that Calhoun assumed the CEO position in January 2020.
“It’s been a long 10 years,” she postulated.
“Yes, it’s been a long 20 years,” Calhoun replied.
These two sentences couldn’t describe the situation at Boeing more clearly.
Although Calhoun had been on the Board of Directors since 2009, including serving as lead director, the challenges he faced with the 737 MAX grounding were greater than he expected. Two months after becoming CEO, the COVID-19 pandemic erupted. And seven months later, deliveries of the 787 were suspended.
The MAX and 787 issues went on much longer than anyone expected. (The MAX challenges still aren’t over.) Recovery from the pandemic is going better than forecast.
The Chamber’s Aerospace Summit was an in-person event. The previous one was in March 2020.
Engine Development. Part 10. Next generation engines

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.
Pontifications: Energy costs add to aerospace supply chain squeeze
By Scott Hamilton
Oct. 17, 2022, © Leeham News: The aerospace supply chain faces new strains due to rising energy costs, Airbus CEO Guillaume Faury said last week.
Bloomberg News reports that Faury said some suppliers are shutting down due to high costs.
“We see another thing coming, which is the consequences of energy prices skyrocketing leading to some suppliers trying to adapt, sometimes stop producing, waiting for the situation to normalize,” he said. “That’s very low in the supply chain, but it’s probably something new,” Bloomberg wrote. It was reporting on Faury’s appearance before the UK Aviation Club.
At an unrelated event last month, two top US suppliers said they continue to see financial distress in the supply chain. Some lower-tier suppliers had filed for bankruptcy and more may be expected.
Engine Development. Part 9. Gearbox or not?

Introduction
October 13, 2022, © Leeham News: In our series, we look at the development of the latest single-aisle engines. Should these be geared? What do you gain and risk with a geared design? Is this a new development, or has it been around for a long time?
We examine the development of single-aisle engines since 2000, their fuel efficiency, and operational reliability.
Summary
- A geared design fixes some fundamental problems in a two-shaft turbofan.
- CFM proves you could just as well further develop what you have.
Engine Development. Part 8. Throttle push or not?

Introduction
October 6, 2022, © Leeham News: The early years of 2000 saw new engine programs launched for the new Boeing 787 Dreamliner and Airbus response, the A350.
Substantial differences in the life of these aircraft programs made the engine programs develop differently. It was about throttle push or not.
Summary
- The Dreamliner engines changed as the 787 programs went through many stages.
- The Airbus A350 program was a standard program in comparison.

Introduction
September 29, 2022, © Leeham News: The 1970s saw the introduction of the High Bypass engine for the medium/long range Boeing 747, Douglas DC-10, and Lockheed Tristar, with Airbus A300 employing an updated variant of the DC-10 engine for medium range missions.
In the following decades, these engines introduced improved technology and matured into new levels of reliability. With the increase in reliability came changes in how long-range aircraft were designed.

Summary
- The engine development after the introduction of the high bypass turbofans in the 1970s focused on reliability and higher efficiency rather than new design principles.
- The change in reliability made the two-engined long-range aircraft the winner over three and four-engine aircraft.
Boeing shows off new Additive Manufacturing facility, a key to future aerospace
By Scott Hamilton
Sept. 28, 2022, © Leeham News: Boeing last week officially celebrated the opening of its Boeing Additive Manufacturing plant (BAM) in the small suburb of Algona (WA), east of Tacoma.
BAM opened just at the start of the COVID-19 pandemic in March 2020. But ceremonies were postponed until now.
Additive manufacturing (AM) is not new to Boeing. It’s been doing AM in various forms for 30 years. But increasingly, companies are turning to AM to reduce costs and production time. Also known as 3D printing, companies are using AM for tooling, parts, and small components from civil and commercial aviation to defense and space programs. Parts are used on airplanes, drones, and spacecraft.
Many homes and non-aerospace businesses have 3D printers. Some are for business and others are for hobbyists. As part of a media and VIP tour last week, guests received gifts of two small airplanes created by 3D printing, one metal, and one plastic (plus a box of two chocolates, not made by AM, but the real thing).

Pontifications: Single-pilot jetliners OK for cargo, not yet for passenger airplanes
By Scott Hamilton
Sept. 26, 2022, © Leeham News: I sat down with Fred Smith, the founder and now executive chairman of FedEx, on Sept. 15 at the US Chamber of Commerce Aerospace Summit. The first article appears here.
The balance of the interview covered a wide range of topics. I’ll summarize them below.
Engine Development. Part 6. High Bypass goes mainstream

By Bjorn Fehrm
Introduction
September 22, 2022, © Leeham News: With the introduction of the High Bypass engine for the Boeing 747, Douglas DC-10, and Lockheed Tristar, it was obvious Pratt & Whitney’s low bypass engines on the Boeing 707, 727, 737, and Douglas DC-8, -9 should be attacked with a new High Bypass engine in this thrust class.
French Snecma and GE teamed up to break Pratt & Whitney’s monopoly of the jet engine market outside the widebodies. The CFM56 was born.

Summary
- With an exclusive fit on the Boeing 737 and a 10-year introduction advantage on the A320, the CFM56 has dominated over the competing IAE V2500.
- The CFM56 is the world’s most produced jet engine, with over 32,000 engines produced to date.
Boeing shows FedEx concepts for 787F and NMA-F

Sept. 20, 2022, © Leeham News: FedEx last week withdrew its previous financial guidance for the year on a revised analysis. Now, the company says, revenues will be about $500m less for air operations and about $300m less for ground operations.
The flagging global economy and higher costs are blamed. As a result, FedEx will be parking an unspecified number of airplanes and implementing cost savings initiatives.
But at the same time, the company is evaluating new aircraft freighters and potentially acquiring and converting used Boeing 777-300ERs to freighters.

In an interview on Sept. 15, the same day the financial forecasts were revised, Fred Smith told LNA that the airline is evaluating the 777-300ER aftermarket conversions and new airplanes offered by Airbus and Boeing.
The Boeing concepts include the proposed 787F and a freighter version of the New Midmarket Airplane (NMA). LNA revealed months ago that Boeing was studying both of these aircraft. Boeing already launched the 777-8F, another option for FedEx. Airbus has offered the A350F to FedEx. Smith said he’d like to see Airbus launch a new-build freighter version of the A321neo.
