January 26, 2026, © Leeham News: Pratt & Whitney (PW) bet big on the geared turbofan to take it back to a sizeable position in the market’s largest airliner segment, the Single-Aisle. It spent more than 20 years to develop the fan gearbox, including functional demonstrator engines that flew on Airbus test aircraft to prove the technology.
The effort was a success; the gearbox in the Pratt & Whitney range of Geared TurboFans, GTFs, has worked perfectly. It achieved what was promised, a low fuel consumption, and has been rock-solid in its function.
Yet PW’s GTFs have had a range of problems since their introduction in 2016. Bent main shafts, combustors that burn through, bearings that fail. And on top, a huge call-back of engines, as a contaminated power metal process has produced compressor and turbine discs that risk failing before their on-engine life expires. The situation has caused over 600 Airbus A320 and A321neos with GTF engines to be grounded for engine replacements, if and when replacement discs are available.
The issues, stemming from the “business as usual” parts of the GTF, have led to write-offs of billions of dollars for PW’s mother RTX and to lost market share to the competing CFM LEAP engine on the Airbus A320/321neo series. But while this clouds the business of yesterday and today, Pratt & Whitney still has the clout to invest in the future. Being part of one of the World’s largest Defence and Aerospace Companies is an important part of the answer.

July 10, 2025, © Leeham News: It’s official: Lars Wagner becomes CEO of Airbus Commercial Aircraft on Jan. 1. He will succeed current CEO Christian Scherer, who will retire after 40 years at Airbus.
Word of Wagner’s appointment leaked months ago.

Wagner joins Airbus on Nov. 1 to begin a two-month transition. He is currently the CEO of MTU Aero Engines, a position he assumed in 2023. He joined MTU in 2015. Before that, he held various positions at Airbus. He is an engineer.
Wagner’s appointment may cast a question over GE Aerospace’s campaign with Airbus to choose the RISE Open Fan engine for the latter’s new single aisle aircraft intended to replace the A320neo family.
During the Paris Air Show last month, Airbus Group CEO Guillaume Faury said Airbus plans to decide on the engine to be selected for the A3XX around 2027-2028. A program launch target is 2030 with an entry-into-service target of 2038.
Engine makers tout “Plan A” but have “Plan B” backups in R&D

June 23, 2025, © Leeham News, Paris: CFM International touts its Open Fan RISE engine as the wave of the future. (CFM is a 50-50 joint venture between GE Aerospace and Safran.)
Rival Pratt & Whitney says evolution of its Geared Turbo Fan is the best engine choice going forward.

Neither company will admit that it is also researching and developing a Plan B engine. For CFM, this is a conventional turbofan. For PW, this is a new Open Fan. But during the Paris Air Show, LNA confirmed that both have a Plan B engine in development.
PW has gone out of its way to dismiss the very idea of an Open Fan engine. Rick Deurloo, the president of Pratt & Whitney Commercial, won’t even talk about the “competitor.” Deurloo makes it clear—publicly, at least—that an evolution of PW’s Geared Turbo Fan (GTF) is the best solution for the next generation engine for the single aisle market, in its view.
Mike Winter, RTX’s Chief Engineer, dismissed the Open Fan as “sub-optimal” on a successor to the Airbus A320neo and Boeing 737 MAX families. It involves too many installation compromises on this size aircraft, he says. RTX is the parent of PW.
But, says one person with direct knowledge, PW fully understands that if CFM is successful in solving all the challenges of an Open Fan and meets the publicly stated goal of improving fuel consumption by 20% compared with today’s GTF and CFM LEAP engines, PW’s gain of an evolutionary GTF won’t be competitive.
So, says the person with direct knowledge of PW’s activities, the development of an Open Fan alternative engine is being worked on as PW’s Plan B.
Furthermore, PW’s sister company, Pratt & Whitney Canada, publicly disclosed its development of an Open Fan engine in a briefing on Tuesday this week. This engine is for a new 70-100-seat aircraft designed by the start-up company MAEVE. PW is following PWC’s development.
Heart Aerospace’s revised ES-30, Part 2

October 17, 2024, © Leeham News: We analyze Heart Aerospace’s latest evolution of the hybrid ES-30 (bottom aircraft in the picture), which replaces the original battery-based 19-seater (top aircraft) and the original ES-30 (mid aircraft).
The latest version, presented in spring 2024, is a parallel hybrid, putting gas turbine turboprop engines outside the electric motors. What are the advantages of the parallel hybrid version, and will it make the Heart ES-30 project more likely to succeed?
We use our Aircraft Performance and Cost Model (APCM) to understand the design choices and the costs involved.
Summary:
- The latest revision of the Heart Aerospace hybrid electric aircraft, the ES-30, takes the hybrid architecture from a serial to a parallel system. It simplifies the architecture.
- Does the revised ES-30 make airline operational sense? We analyze this using our Aircraft Performance and Cost Model.
Maeve, P&W Canada team for new hybrid propulsion system airplane
By Bjorn Fehrm and Scott Hamilton
July 24, 2024, © Leeham News at Farnborough International Airshow: Start-up airplane company Maeve and Pratt & Whitney Canada (PWC) have teamed for the design of a new eco-airplane driven by a new type of hybrid electric propulsion system with a target service entry date of 2032.
The M80 aircraft is the latest iteration of a design conceived by Maeve of the Netherlands. It is a 76 to 96-seat twin-engine aircraft that is compliant with the restrictive US pilot Scope Clauses, which limit the size, number, and weight of airplanes operated on behalf of US major airlines. Maeve originally designed a four-engine, 44-passenger electric aircraft called the M01.

A Chinese intervention in Ukraine would kill its aerospace industry

Commentary
March 23, 2023, © Leeham News – Chinese leader Xi Jinping flew into Moscow this week for a three-day summit with accused Russian war criminal Vladimir Putin.
They wined and dined. They talked publicly about economic accords and oil pipelines and pledged mutual support. In private, Putin almost certainly made a plea for stepped-up Chinese support for his faltering invasion of Ukraine. They made bold statements about banding together to oppose the hegemony of the West, which has united against Russia with sanctions including bans on providing Russia with the basic technology it needs to build weapons.
And at the end of it all, on Wednesday, Xi walked up the jet stairs to his Air China 747, built by Boeing in Everett, America. He turned and waved, and then flew back to Beijing.
That moment, with Xi standing in front of the massive American-made jet, may just illustrate China’s conundrum right now: Xi, by all accounts, wants nothing more than to shove aside the post-Cold War order that has confined his nation from global Great Power status. An alliance with Putin’s Russia could be a key step toward that.
And Xi, as he looks around the interior of his jumbo jet, has to be acutely aware that China remains dependent upon the Western democracies for software, computer chips, and – critically – aircraft.
- War has created headaches for aerospace
- Chinese tensions are bigger issue
- China loses in a proxy war with West
- Boeing’s China business is effectively frozen
- Airbus in China may also be at risk
P&W, Collins Aerospace launch hybrid-electric demonstrator
By Scott Hamilton
July 18, 2022 (BST), © Leeham News: Pratt & Whitney and sister company Collins Aerospace announced the launch of a hybrid-electric technology demonstrator, it was announced today at the Farnborough Air Show. This program is for future advanced air mobility vehicles.
Collins and Pratt & Whitney Canada, the turboprop engine unit, also announced the completion of the preliminary design of a 1MW motor for the demonstrator. A De Havilland Canada Dash 8-100 will be the platform for the commercial hybrid-electric application.

March 4, 2022, ©. Leeham News: This is a complementary article to Part 9. Parallel Hybrid. It uses Leeham Company’s Aircraft Performance Model from our consultancy practice to analyze the design of a Parallel Hybrid aircraft for regional operations.
Our design brief is to make turboprop upgrade packages for De Havilland DH8-200,-300, and-400 aircraft. By using a Parallel Hybrid we could “target a 30% reduction in fuel burn and CO2 emissions, compared to a modern regional turboprop airliner” according to Pratt & Whitney Canada. Time to check if we can reach these levels.
