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 summary of the article Part 9P. Parallel Hybrid, the Deeper Discussion.
We look into the Pratt & Whitney, Collins Aerospace, and De Havilland project to create a Parallel Hybrid propulsion alternative for the Dash 8 turboprops.
The project “targets a 30% reduction in fuel burn and CO2 emissions, compared to a modern regional turboprop airliner” according to the Pratt & Whitney press release.

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.
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.
Why was the 737-8 losing market to the A320neo before the MAX crisis?

Introduction
February 27, 2020, © Leeham News: While we wait on the Boeing 737-8 to get back in the air, we take a look at how this best seller in the 737 series compares with its direct rival, the Airbus A320neo.
The 737-800 and its follow on, the 737-8, have been the most popular single-aisles in Boeing’s lineup for decades. The 737-800 sold more units than the A320. But when both got re-engined, this changed. The A320neo is now outselling the 737-8.
We look into why.
Summary:
- The trend where the A320neo is outselling the 737-8 started well before the MAX crisis. Is the root cause better airframe performance?
- We find the cause to be another. The difference is not about a change in relative airframe performance between the two.
Europe’s Regional airlines meet in Antibes, Cotes d’Azur.
By Bjorn Fehrm
October 9, 2018, ©. Leeham News, Antibes France: The European Airlines Association, ERA, gathered 44 of its 51 member airlines in Antibes France, today for the first day of its 2019 General Assembly meeting.
LNA participated in the event for the first time and we found an impressive gathering of airline and airport representatives, aircraft OEMs and support businesses discussing the challenges facing the European regional air transport market.
Norway’s Wideroe, the launch customer for Embraer’s E-Jet E2 is one of the airlines present.
Embraer’s E195-E2 or Airbus’ A220-300 for the 120 to 150 seat segment?

Introduction
September 19, 2019, ©. Leeham News: What aircraft to choose for the segment 120 to 150 seats, Embraer’s E195-E2 or Airbus A220-300? After discussions with Airbus’ Rob Dewar at the Paris Airshow, Head of A220 Engineering and Product Support, and a visit to Embraer last week for the E195-E2’s first customer delivery, we have collected some unique insights.
We also had the opportunity to talk to David Neeleman of Azul, Moxy and TAP Portugal when at Embraer, the only owner/operator which has bought both aircraft; E195-E2 for Azul and A220-300 for his Moxy project.
Summary:
- We start with a detailed comparison of the aircraft in this first article.
- While serving the same passenger capacity segment, they are surprisingly different in their design approach and, therefore, in their characteristics.
Collins Aerospace faces new merger before previous one is fully integrated
July 16, 2019, © Leeham News: Ajay Agrawal, the president of Collins Aerospace’s aftermarket services, wasn’t done integrating the 
merger between United Technologies and Rockwell Collins.
He now faces a new integration with the planned merger between United Technologies (Collins’ parent) and Raytheon. The new company will be called Raytheon Technologies. There’s little he can do until the merger is approved by regulators, except plan internally how to integrate and expand the aftermarket business.
Pontifications: Collins Aerospace resolved to compete for aftermarket services
By Scott Hamilton
April 22, 2019, © Leeham News: Moves by Airbus, Boeing and Embraer to increase their shares of aftermarket services are viewed by their own suppliers with a mix of trepidation or resolve, depending on who they are.
For Collins Aerospace, it’s resolve.
It’s also about become more efficient with advanced manufacturing of its parts supplied to the aerospace industry. This reduces costs, lead times and takes advantage of Collins’ own engineers and designs for value-added services to its customers.
I spoke with two officials from Collins at the Aviation Week MRO Americas conference in Atlanta April 9-11.
Collins contract vote keeps 737 landing gear on track
By Bryan Corliss
March 11, 2019 (c) Leeham News: Workers at the Collins Aerospace landing gear plant in Everett, WA, have approved their first union contract with the company.
Both sides can come away feeling OK with how they did at the bargaining table. But the biggest winner in these talks actually was Boeing, which now doesn’t have to worry about a break in the flow of 737 landing gear for the next 40 months.
