February 12, 2021, ©. Leeham News: After covering the basics of fuel cells last week in our hydrogen airliner series, we now look at what type of system to choose for aircraft propulsion and onboard systems power.
We analyze the propulsion side this week.

Jan. 11, 2021, © Leeham News: COVID-19 may ultimately prove to be a net positive for turboprop manufacturers. Near-term orders will be pinched just as for jets, but a long-term loss of business travel and the resulting impact to airline yields will make turboprops’ superior unit costs appealing for shorter missions.
Turboprop engines create their thrust with a very high bypass ratio. The result is 30% better fuel economy than a jet. But it also means 30% lower speed. This limits turboprops to stage lengths to about half that of jets.
The market-dominating ATR and De Havilland Canada (DHC) turboprops use this base efficiency to compete against newer regional jets despite having designs which are 20 years older.

September 28, 2020, © Leeham News: The worldwide COVID-19 pandemic is shaking the air travel and airliner manufacturing industries like no crisis before.
More than 9/11, the oil crisis of 1973 or 2005 or the financial crisis of 2008. The problems for the airlines and the airframe OEMs are on the front pages of the world’s media.
The part of the airliner industry that is not so visible but is perhaps hardest hit, is the engine industry. Its weird business model amplifies the effects of the crisis.

June 15, 2020, © Leeham News: John Slattery, the CEO of Embraer Commercial Aviation, was named CEO of GE Aviation, it was announced today.
Arjan Meijer is the new President and CEO succeeding Slattery. Slattery succeeds David Joyce, who is retiring. Slattery’s appointment is effective July 13.
Slattery devoted much of the last year trying to win approval of the proposed Boeing-Embraer joint venture, Boeing Brasil-Commercial. Boeing terminated the agreement April 25, claiming Embraer failed to meet all required terms and conditions. Embraer claims it met the conditions. Both took the dispute to arbitration.
Slattery had been designated CEO of Boeing Brasil. After the deal’s collapse, his departure from Embraer was expected.

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.
Oct. 9, 2017, © Leeham Co., Montreal: The National Business Aviation Assn. (NBAA) annual exhibition begins tomorrow in Las Vegas.
LNC doesn’t ordinarily follow business aircraft, but when I was in Montreal last month visiting Pratt & Whitney Canada, I had the opportunity to meet with leaders of the PW800 team.
This new engine powers the new Gulfstream 500/600, a corporate aircraft undergoing testing.
Admittedly, not being conversant with the G500/600 or the PW800, details of which may be not new to some others, I was taken by a fewer pointers shared by PWC.
