Airbus aggressively seeks to reduce corporate, industry emissions footprint

April 25, 2022, © Leeham News: Airbus is charging ahead with its ZEROe ecoAviation research and development, focused on hydrogen (H2) power while supporting efforts for Sustainable Aviation Fuel in the meantime. Airbus targets 2035 for a commercial airliner, which will almost certainly be a turboprop—not a jet.
Boeing previously said it believes Sustainable Aviation Fuel (SAF) is the near-term answer for greening up commercial aviation. By 2030, all its aircraft will be capable of 100% SAF use. Airbus is heading down this path, too.
Airbus believes H2 is the best solution to achieving zero emissions. Battery-powered airplanes and eVTOLs and battery-hybrids are other alternatives. Each has big technical and/or supply challenges to overcome.
In a webinar last week, Amanda Simpson, VP of Research and Technology for Airbus, said designing an entirely new airplane for H2 opens the possibility of an entirely new, high-tech wing design for which other research has been underway. A “Wing of Tomorrow” has been under development for years. Airbus already is pursuing an UpNext eXtra Performance Wing. For shorthand, LNA will identify this as the UNePW.

April 15, 2022, ©. Leeham News: Last week, we examined different airliner types’ power requirements and the importance of their size classes in the market.
Now we look at what propulsion system alternatives are available when using hydrogen as the energy source and their principal advantages and disadvantages.

An A330neo freighter, should it happen? Part 2

Introduction
April 14, 2022, © Leeham News: Last week, we speculated that Airbus might decide to upgrade the present A330-200F freighter to a neo variant based on the longer -900 fuselage.
To understand how competitive it would be, we compare its economics to the 787, 767-300F, and A330-200F freighters.
Summary
- Airbus’s A330-900F would be a modest upgrade project, as all bits needed are in production today.
- The result would outcompete all present midrange freighters and give a 787 freighter a match in the market.
Airbus nears finding homes for Air Asia X, Aeroflot widebodies

April 11, 2022, © Leeham News: Airbus removed nearly all A330-900s from its backlog to AirAsia X, finally acknowledging what the industry knew for years: this deal was toast, even before the pandemic burnt it.
There are also A350-900s for Aeroflot that now no longer can be delivered.

Despite the widebody marketing being in the dumps, likely for another couple of years, don’t fret about these lost orders. According to market intelligence, Airbus has perhaps three campaigns for the A330neo that may jell within the new few weeks or months.
And the Aeroflot A350s may have a home sooner than anyone would think. Furthermore, some may wind up going to a customer with orders for the Boeing 787 that are in limbo because of the 18-month suspension of deliveries.
Furthermore, Airbus is quietly working to consolidate its dominance in the single-aisle market as the COVID pandemic continues to wind down and Boeing has challenges ramping up its 737 production—and certification of the 737-10 MAX by year-end seems slipping. The ramifications of this slip could be profound.
Summary
- Airbus lining up customers to take Air Asia X canceled A330-900s.
- Aeroflot A350s may find home soon, with a customer awaiting 787 deliveries.
- Boeing’s 737 production rate plans were affected by the China Eastern crash.
- China Eastern crash cause appears trending toward pilot suicide.
Pontifications: Catching up—DHC extends Dash 8 life; 737-10, 777X, A321XLR certifications
Every once in a while, it’s necessary to catch up on this and that….
By Scott Hamilton
April 11, 2022, © Leeham News: The announcement drew little notice because the topic wasn’t sexy. De Havilland Canada last week said that Norway’s Wideroe Airlines became the first operator to sign up to extend the service life of its Dash 8-100s from 120,000 cycles to 160,000 cycles. The carrier previously contracted to extend the life of the Dash 8 from 80,000 cycles to 120,000 cycles.
“Combined, our two Extended Service Programs add another 30 to 40+ years to the operational life of Dash 8-100 aircraft – that’s double the original service life of the aircraft,” DHC’s Robert Mobilio, Vice President Engineering, said in a statement.
The move is significant because there are no replacement aircraft in the 30-seat category. The market for airplanes this size is very small, and any replacement aircraft would likely be beyond the financial reach of many regional carriers. Extending the life of these airplanes—for an astonishing 30-40 years—is the only viable alternative.
DHC is separately evaluating hybrid technology, with engine maker Pratt & Whitney Canada, to make the Dash 8 series more environmentally friendly. A Dash 8-100 will be used for the hybrid-electric demonstrator.

April 8, 2022, ©. Leeham News: Last week, we discussed the architecture of a liquid hydrogen fuel system. We now start looking at the propulsion system of a hydrogen aircraft.
Before discussing how a propulsion system is done, we must understand what power requirements different airliner types have and the importance of these types in the market.

An A330neo freighter, should it happen?

By Bjorn Fehrm
Introduction
April 7, 2022, © Leeham News: Last week, we started a discussion on what should be Airbus’ response to a 787 freighter. We have seen in a series of articles that the 787 freighter would beat the present A330 freighter, and the question is, will Airbus leave this segment to Boeing, or will it respond?
We look at what’s involved for Airbus to upgrade the present A330-200F to a neo freighter and what performance it would have compared to a 787 freighter.
Summary
- An upgrade of Airbus’ present A330-200F freighter to a neo variant based on the longer, more capable A330-900 would be a modest project for Airbus. All the special bits needed were developed for the A330-200F.
- The resulting A330-900F would be a competitive freighter, and as all needed parts are in serial production today, it could hit the market before a Boeing 787 freighter.
Pontifications: Returning MAX to pre-grounding rate one key to Boeing’s launch of new airplane
April 4, 2022, © Leeham News: Returning the 737 MAX production rate to pre-grounding levels, and beyond, is a key element to positioning Boeing to launch a new airplane program.
By Scott Hamilton
So far, Boeing hasn’t provided any guidance to Wall Street aerospace analysts beyond reaching a rate of 31/month this year.
A month ago, LNA reported that hints of new rates came from Boeing suppliers ATI and Spirit Aerosystems during their investor day presentations. The two days were a week apart. ATI is a parts supplier. Spirit builds entire fuselages for the 737. The investor days suggested that Boeing will return to rate 52, the pre-ground MAX rate, by 2024.
LNA has learned more specific information from its sourcing in the supply chain. Boeing notifies the chain when to expect rate breaks to higher or lower rates for planning purposes.
According to LNA’s latest information, Boeing is planning to achieve a rate of 38 by January 2023 and boost it to a rate of 47 by the summer of 2023. Another rate break would boost production to 52 a month early in 1Q24. When regulators grounded the MAX in March 2019, Boeing was geared up to boost production to 57 a month by year-end.
So far, Boeing apparently hasn’t given guidance to its supply chain beyond rate 52. But if the pattern holds up, rate 57 could be in the cards by the end of 2024. Orders for the MAX, especially for the MAX 10, have picked up nicely.

Introduction
March 24, 2022, © Leeham News: Last week, we discussed the creation of a Boeing 787 freighter. It shall replace the Boeing 767-300F, which is running into emission rule problems in 2027.
After looking at what 787 variant makes for the best freighter, we now compare the economics of the 787, 767-300F, and A330-200F freighters.

Summary
- When a Boeing 787 freighter arrives at the decade’s end, its economics will change the freighter market’s dynamics.
