Introduction
Feb. 28th, 2022, © Leeham News: In recent weeks, we compared the 787-10 Heavy Gross Weight (HGW) performance against the A350-900. The 787-10 HGW will impact sales campaigns against the A350-900 and those of larger aircraft, the A350-1000 and 777X, and large freighters.
LNA now analyses the potential replacement market for very large aircraft (seating 350 or more passengers in standard configurations) and large factory-built freighters.
Summary
- Large twin-aisle campaign opportunities;
- Passenger and cargo fleet commonality considerations;
- Large factory freighter operators.
Pontifications: Ukraine impact on commercial aviation
By Scott Hamilton
Feb. 28, 2022, © Leeham News: The clouds are very dark over Ukraine today. The unprovoked invasion of Ukraine by an international autocratic lying amoral thug is horrible. What the implications are for neighboring European countries, the greater Europe, the US, and the rest of the world won’t be fully understood for months.
But reality is reality, and LNA’s focus on commercial aviation must look at things from this perspective—narrow as it is in the context of human tolls underway in Ukraine now. In the dark cloud of the Ukraine crisis, we must look at what the impacts might be on commercial aviation.
Bjorn’s Corner: Sustainable Air Transport. Part 8. Serial Hybrids.
February 25, 2022, ©. Leeham News: This is a summary of the article Part 8P. Serial Hybrid, the deeper discussion.
We take an ES-19 type of battery aircraft and add a range extender to avoid the inadequate range we found in Part 6 and 6P.
Initially, it seems a good idea. We can use the benefits of the battery and then complement it with energy from the range extender. As you systematically work through the concept, the problems surface.

February 25, 2022, ©. Leeham News: This is a complementary article to Part 8. Serial Hybrid. It uses Leeham Company’s Aircraft Performance Model from our consultancy practice to analyze the design of a hybrid aircraft for short-haul commuter operations.
Our design brief is to make an aircraft that uses a minimum of carbon-based fuel by combining battery-based energy with energy from a generator driven by a gas turbine. Such a combination is called a Serial Hybrid.

HOTR: Putin can shut down commercial aviation, consultant warned
Feb. 24, 2022, © Leeham News: The invasion by Russia into Ukraine could shut down commercial aviation production, a supply chain consultant expert predicted earlier this month.
Kevin Michaels, managing director of AeroDynamic Advisory, a supply-chain consulting firm, warned at a supplier conference Feb. 8 that Russian President Vladimir Putin “could shut down the commercial aerospace business if he chose to do so.”
A Boeing 787-10 HGW, how good is it?

Introduction
February 24, 2022, © Leeham News: The CEO of Boeing Commercial Aircraft (BCA), Stan Deal, said at the Singapore Air show the company worked on increased gross weight versions of both the 787-9 and -10.
Target is to get the 787-10 to the range of the aircraft it shall replace, the 777-200ER and -300ER. It means more than 7,000nm of range against the 6,400nm of today.
How many tonnes of increased Gross weight does this mean, and what would be the performance compared with the Airbus A350-900? We use our airliner performance model to find out.
Summary
- The 787-10 can grow to a range of over 7,000nm with a modest increase of its gross weight.
- It will be competitive with the A350-900 but for the longest routes in such a variant.
Airbus and CFM reveal ZEROe demonstrator aircraft
February 22, 2022, © Leeham News: Airbus and the CFM partners, GE Aviation and SAFRAN, presented a ZEROe Sustainability demonstrator today that builds on a heavily modified A380 prototype.
On the rear roof of the A380, a pylon is integrated where a hydrogen combustion GE Passport engine is mounted, feed with hydrogen from a sealed enclosure on the main deck that contains four liquid hydrogen tanks.
The choice of the A380 for the demonstrator allows a lot of test equipment and test engineers to be housed in the test aircraft, monitoring the functioning of the propulsion system.
The demonstrator will start the flight tests end of 2026 to prepare decisions around the 2035 Hydrogen passenger aircraft configuration for 2027.

HOTR: Collins Aerospace sustainability
Feb. 22, 2022, © Leeham News: The headlines and debate over ecoAviation focus on the airframe and engine manufacturers, for good reason. But the aerospace supply chain is mindful of its ESG (Environmental, Social, and Governance) issues as well.
Pratt & Whitney makes the engines that emit emissions and burn fuel. It works to reduce fuel burn and emissions. PW also is exploring electric, hybrid and hydrogen alternatives. Sister company Collins Aerospace works to find solutions to reduce emissions in other areas.
“We play a big role in sustainability,” says LeAnn Ridgeway, Vice President, Sustainability. Collins purchased FlightAware, which is perhaps best know for flight tracking in competition with FlightRadar24. But FlightAware provides route planning and ADS-B services, among others.
Pontifications: Advice for Boeing in the coming KC-Y campaign
Part 6: The KC-X competition from Boeing’s perspective
By Scott Hamilton
Feb 21, 2022, © Leeham News: Jim Albaugh, the former president and CEO of Boeing Commercial Airplanes and of Boeing’s defense unit, retired from the company in 2012. He oversaw the first competitive bid at the defense unit for the US Air Force KC-X refueling tanker. That was lost to Northrop Grumman-EADS (Airbus) in 2009.
As CEO of BCA, he oversaw commercial efforts to get Boeing’s cost down on the 767-200ER, which formed the basis for what became the KC-46A tanker. Defense won this round against a solo EADS bid. Boeing’s winning price was about 10% below the EADS bid for its A330-based MRTT.
Years removed from Boeing but nevertheless an interested observer with experience on the losing and winning bids, Albaugh has some observations and advice as Boeing prepared to compete against Lockheed Martin-Airbus for the KC-Y campaign that already has unofficially begun.
For next new airplane, Pratt appears to trail CFM for next new engine

Feb. 21, 2022, © Leeham News: As Boeing ponders whether to launch a new airplane program and industry consensus seems to be that this must happen in 2023 or 2024, Pratt & Whitney seems to face a dilemma.

Convinced that the Geared Turbo Fan technology is the path to future engines, nevertheless, public statements indicate that by 2035, the GTF in the conventional form will fall short of the Open Fan being developed jointly by GE Aviation and Safran. GE and Safran are 50-50 partners in CFM International, which will sell the engine.
Rick Deurloo, the chief commercial officer for PW, told LNA last October that by 2031 (at the time, 10 years in the future), the GTF will have a 10% improvement in fuel burn and emissions compared with today’s GTF. PW will have a 1% improvement by 2024.
GE’s Travis Harper, who is the program manager for the Open Fan “RISE” engine under development, told LNA earlier this month that the RISE will reduce fuel consumption and emissions by 20% and be ready for entry into service by 2035.
If the goals outlined by Deurloo and Harper are taken at face value and achieved, this means the GTF will be up to 10% short of CFM’s engine ready for EIS four years later.
This was the question LNA put to other representatives of GE and PW at the Pacific Northwest Aerospace Alliance conference Feb. 10.
