Merry Christmas and Happy New Year
By Scott Hamilton
Growing up in the Chicago suburbs, my family would occasionally trek down to the Chicago Museum of Science and Industry at Christmas time. The main attraction then was not all the very cool stuff in the Museum, including the German submarine U-505, a full-size replica of a coal mine, and locomotives.
At this time of year, it was to see the Christmas Around The World display–a tradition that is now 80 years old. Even as a child, it was amazing to see how different cultures celebrated Christmas. Here’s a taste.
LNA has some prepared posts between Christmas and New Year. Otherwise, we are taking the holidays off and return Jan. 2, 2023–unless there is compelling breaking news.
So with disdain for political correctness, Merry Christmas and Happy New Year.

Bjorn’s Corner: Sustainable Air Transport. Part 51. eVTOL wrap.
By Bjorn Fehrm
December 23, 2022, ©. Leeham News: After 25 articles about the eVTOL, it’s time for a wrap. We have looked at most aspects of this new form of air transportation, including how sustainable it is.
Today we summarize what we found before we go on to the next subject in Sustainable Air Transport.

Universal Hydrogen’s ATR72 Project

Dec. 22, 2022, © Leeham News: Last week, we wrote about Universal Hydrogen’s (UH2) plans to fly a hydrogen-fueled demonstrator aircraft in early 2023, followed by a certified conversion kit for an ATR72 airliner mid-decade.
The plans for the ATR72 hydrogen conversion are at an advanced state. As the first publication, we can describe the overall design and the technical details. The ATR72 implementation brings improvements in several areas compared with what’s been revealed before.

Summary:
- The target ATR72 conversion improves hydrogen capacity and handling compared to earlier concepts.
- The influence on the ATR seating capacity is reduced due to more efficient packaging on the aircraft.
HOTR: Supply chain hurts A220 assembly flow, big push to meet year-end delivery target
By the Leeham News Team
Dec. 20, 2022, © Leeham News: Airbus’ woes with the A320 family production line are widely reported. So are Boeing’s woes with the 737 line.
Less well reported are the woes Airbus has with the A220 production lines in Montreal and Mobile (AL).
LNA was informed two weeks ago that the A220 line is its own serious production challenges traced to the supply chain. Rumors circulated that Airbus may shut down the lines to allow the suppliers to catch up.
Airbus’s Montreal office acknowledged challenges but denied the final assembly lines were going to be or were considered for shut down temporarily.
“In order to protect our operations in a complex environment, some ad hoc short-term planning adjustments have been made to align with our supply chain in order to protect our deliveries to our committed customers. We continue to focus on the aircraft that are almost ready for delivery in 2022 and there is no shutdown either of FALs nor pre-FALs planned,” a spokesperson emailed LNA.
Suppliers expect Boeing to increase 787 rates next year

Dec. 19, 2023, © Leeham News: Boeing suppliers are planning to increase their output to support the OEM’s plan to deliver five new-built 787s a month at some point in 2023.
Boeing wants to increase the production rate of the 787 to 5/mo by the end of 2023 and to 10/mo by 2025. The supply chain must hurry to prepare. Credit: Leeham News.
It will be challenging for the top-tier suppliers to scale up operations dramatically. They’ll have to train and maintain larger teams of workers, while also ensuring that their own lower-tier suppliers have the capacity to deliver parts and components on time.
One executive warned investors this fall that the challenges in the year ahead will be greater than the ones the industry faced delivering record numbers of planes before the pandemic.
Summary:
- Howmet: ‘Back of the year, at around 5 per month’
- Suppliers want more lead time given challenges
- Whole supply chain is under stress

Pontifications: Nope, not convinced about Boom’s new entrant engine plans
Dec. 19, 2022, © Leeham News: Nope. Not convinced.
By Scott Hamilton
Boom’s CEO Blake Scholl last week announced that he’s put together a group of three companies to work with his firm to design an engine for his Overture supersonic transport.
None of the companies—including Boom—has designed a big jet engine, let alone one for a commercial airliner or an SST.
Yet Scholl said Overture’s first flight will slip only a year, from 2026 to 2027, and entry into service is still set for 2029.
No way will this happen.

The three companies are Florida Turbine Technologies, which will design the engines; GE Additive, which will consult on ways to fabricate engine parts through additive manufacturing technology; and StandardAero, which will be Boom’s MRO partner and will consult on making the engines easy to maintain.
Florida Turbine is a subsidiary of Kratos Defense & Security Solutions. It has designed small jet engines for drones and cruise missiles. But not for big jets or SSTs.

Bjorn’s Corner: Sustainable Air Transport. Part 50. eVTOL production volumes.
By Bjorn Fehrm
December 16, 2022, ©. Leeham News: Last week, we looked at the production costs of our typical eVTOL. We could see that it was far higher than Joby’s assumption of $1.3m for the S4, about three times higher for units above 500 and even higher for earlier units.
Let’s examine where such cost numbers come from. It’s about production ramp hockey sticks and numbers never seen before. Are these credible?

Universal Hydrogen could be first with Hydrogen Airliner

By Scott Hamilton and Bjorn Fehrm
Dec. 15, 2022, © Leeham News: Universal Hydrogen (UH2) is perhaps weeks away from its first flight of a demonstrator that equips a De Havilland Canada Dash 8-300 with tanks of hydrogen and a fuel cell electric propulsion unit. The project shall prove the feasibility of hydrogen-fueled airliners.
The first flight’s date hasn’t been firmly set, but officials at UH2 told LNA it should be soon. Taxi tests of the aircraft will begin in the coming weeks. The flight will occur at Moses Lake in Central Washington State.
Universal Hydrogen supplies its hydrogen to the aircraft in prefilled barrel-sized tanks, called capsules, to avoid the lengthy and costly investment in storing and filling infrastructure at airports. The proof of concept is with a Dash 8, followed by a complete hydrogen conversion kit for an ATR-72 turboprop airliner.

Summary:
- The core business of Universal Hydrogen is the prefilled hydrogen tanks that load onto the aircraft in pallets.
- Universal Hydrogen builds the complete hydrogen fuel and propulsion system to prove and bootstrap the concept of hydrogen airliners.
UPDATE: Boom announces engine partners for proposed supersonic jet
By Bryan Corliss
Dec. 13, © Leeham News: Boom Supersonic announced this morning that it will team with three partners, including a division of GE, to create engines for use specifically on its proposed Overture passenger transport.
“Developing a supersonic engine specifically for Overture offers by far the best value proposition for our customers,” Boom founder and CEO Blake Scholl said.
The partners are:
- Florida Turbine Technologies, which will design the engines;
- GE Additive, which will consult on ways to fabricate engine parts through additive manufacturing technology; and
- StandardAero, which will be Boom’s MRO partner and will consult on making the engines easy to maintain.
The announcement didn’t specify who will fabricate the engines, or where they will be built. It did note that Standard Aero has experience assembling and servicing supersonic engines for the military. Boom has not yet responded to a request for clarification.
Summary
- Major engine manufacturers had passed on Boom
- Engines could include additively manufactured components
- Significant challenges remain

United orders 100 Boeing 787s, 100 Boeing 737s, defers Airbus A350 again
Dec. 13, 2022, © Leeham News: United Airlines today announced a massive order for 100 Boeing 787s and 100 Boeing 737 MAXes. Sub-types weren’t announced. Neither were the engine types for the 787s, which are powered by either GE Aerospace’s GEnx or Rolls-Royce Trent 1000.
An order for 45 Airbus A350s was deferred again, this time to at least 2030. Deliveries were to begin in 2027. The order had been deferred at least twice previously. Reuters reported “United CEO Scott Kirby told reporters ‘the right time for 350 versus (787) conversation is when we’re replacing the bulk of the 777s, which really doesn’t begin to the end of the decade.’” Most observers believe this order will be canceled eventually.
