Bjorn’s Corner: New aircraft technologies. Part 21. Changed flight profiles
By Bjorn Fehrm
July 14, 2023, ©. Leeham News: Developments in engines and airframe technologies require that the aircraft are flown differently to maximize the benefits.
We start by locking what changes in parasitic and induced drag mean for how airliners fly.

The reality behind the eVTOL industry’s hyperbole

July 13, 2023, © Leeham News: We have done a deep dive series on the cost problems experienced by small airliners and how these make life difficult for alternative propulsion projects.
The eVTOL industry also faces problems, but here it’s more its own overinflated promises that rub. It’s the subject of our next deep dive.
We look at what the top OEMs promised in the past and what the reality is as they come closer to Certification.
When it comes down to it, what missions can be flown and what cannot? Are the missions that can be flown enabling a new industry?

Summary:
- Investor prospects promised Total Available Markets (TAMs) as large as $500billion with flights at up to 200 miles per hour to destinations hundreds of miles away
- The reality is more profane. None of these promises hold water.

Analysis: Spirit strike likely a sign of changing aerospace labor market

July 10, 2023, © Leeham News – In case anyone had slept through all the earlier alarms going off, the whistles and airhorns that sounded during the mercifully short-lived Machinists Union strike at Spirit AeroSystems should have been a wake-up call:
This ain’t the 2010s aerospace labor market anymore.
In the labor market of 2023, hourly workers don’t want to come in on weekends. They want raises, and they’re not interested in getting paid in stock. And don’t you dare think of cutting off payments for the prescription drugs their kids need to take to stay healthy.
All this is going to create a challenge for the aerospace industry. For the past two decades, executives have focused on growing profit margins by holding down marginal costs – especially labor costs.
A decade ago, aerospace companies were able to win labor concessions by threatening to take work away.
Today, it’s the workers who seem to have leverage, and OEMs are going to have to figure out how to keep them happy and productive, or explain to the Kirbys, O’Learys and Al-Baker’s of the airline industry why their planes aren’t getting out of the factories on time.

Bjorn’s Corner: New aircraft technologies. Part 20. Efficient flying
By Bjorn Fehrm
July 7, 2023, ©. Leeham News: We explore different technologies in the series that can make our next-generation airliners more efficient and, thus, less polluting.
We have discussed developments of engine and airframe technologies, such as Turbofans versus Open Rotors and different airframe configurations to minimize drag and, thus, energy consumption.
When utilizing these developments to increase efficiency we must fly the aircraft in a different way depending on the technology.
And how we fly the aircraft is not only influenced by the factors we have discussed. We must consider factors at the airplane level, at the airliner operational level, and finally, at the airline fleet level.

The Small Airliner Problem, Part 10. Cash costs for a battery-based airliner

July 6, 2023, © Leeham News: In our series on costs factors that make up Cash Operating Cost for a battery-based airliner with range extenders, we now add Crew costs and Airport/Airway fees.
We then have all the components of the Cash Operating Cost (COC) for the ES-30 and can compare it to a normal propulsion 30-seat turboprop.

Summary:
- The high operating weight and slow speed of a battery airliner increase the Airport/Airway fees and Crew costs for the ES-30.
- In summary, only one Cash cost remains competitive, and the COC total exceeds the cost of a 30-seater turboprop.

P2F conversion constrained by feedstock, certification issues

July 3, 2023, © Leeham News: As the supply chain chaos of the past two years finally winds down, the air cargo industry is trying to prepare for future growth.

However, in an ironic twist, the industry’s near-to-intermediate term runway is constrained by some forces that propelled its supernormal profitability during the pandemic and recovery.
Thanks to growth in e-commerce, many industry observers revised their long-term growth forecasts upward. Cargo traffic growth estimates vary widely, from Cirium’s conservative 20-year expectation of 3.0% per year to Boeing’s optimistic call for 4.1% annually through 2042.
This year’s demand environment is less rosy as global trade falters, seaport backlogs have mostly cleared, shippers of high-value industrial goods suffer from microchip and other key commodity shortages, and recovering passenger airline service drives a glut of lower-deck “belly” capacity on most trade lanes.
The International Air Transport Association (IATA) recently said it expects air cargo demand to fall by 3.8% and revenues to contract by one-third for the full year. Cargo volumes were already down 5.3% year-over-year through April, said IATA.
Summary
- Express carriers are most exposed to short-term pain, but long-run prospects are brighter.
- Non-express carriers continue to be hard hit by excess capacity.
- Freighter conversion feedstock supply is tight.
- 777 P2F conversion slowed by possible certification issues; Boeing poised to sell more 777Fs?
Machinists at Spirit vote to end strike; will return to work on July 5

June 30, 2023, © Leeham News – Machinists Union members working for Spirit AeroSystems in Wichita, KS, will return to work on July 5, after ratifying a new four-year contract with the company.
Some 63% of Local 839 members voted in favor of the contract on Thursday, union officials said. Spirit’s first offer was rejected by 79% of union members voting.
“This membership vote by the majority of 63% is a move in the right direction for our local,” said Cornell Beard, the president of IAM District 70, the parent organization of Local 839. “Let’s work hard to set ourselves up for the big win in four years too.”
In a statement, Spirit leadership welcomed the yes vote, and said they would “closely coordinate” with suppliers and customers as the company restarts production.
Workers will start today preparing for the production restart after the Fourth of July holiday, the company said. The plant has been closed since June 22, the day after Local 839 members rejected the first offer.
- Strike closes plant for less than two weeks
- Workers get 9.5% raise this year, plus bonus
- Second offer ‘what we worked for’
Bjorn’s Corner: New aircraft technologies. Part 19. Supersonic drag
By Bjorn Fehrm
June 30, 2023, ©. Leeham News: In our discussions about the drag of an airliner, we now cover the most complex drag type, Wave drag, or the drag created when the air goes from subsonic to supersonic flow.
We will focus on the physical understanding of what’s happening as the math behind the drag calculation is complex.
