Guest Scott Hamilton is fresh from the Paris Air Show, and we talk about next-generation aircraft and engines, industry sustainability, the supply chain, and Boeing’s path back. Also, an NTSB safety recommendation for the CFM Leap-1B engine, and the possibility of restarting production of the C-17.

In our conversation with Scott, we looked at some of the technologies that may appear in next-generation aircraft. That includes ducted and unducted engines, as well as developments with geared fans. In public, the OEMs tout their own technology choices, but in reality, they are quietly working on multiple options.
We touch on Boeing’s ability to make the financial investment required to proceed with a single-aisle replacement, and on the company’s path to recovery.
Scott provides some observations on this year’s Paris Air Show, including the low-key participation by Boeing. Scott offers his thoughts on electric aircraft, alternative fuels, and the airline industry goal for net-zero carbon emissions by 2050.
Scott’s book, Air Wars: The Global Combat Between Airbus and Boeing, was published in 2021. This coming September, a sequel titled The Rise and Fall of Boeing and the Way Back will be published and available on Amazon.

Boeing issued a request for information (RFI) to engine manufacturers for advanced ducted propulsion systems in the 30,000-lb-thrust class. That thrust class is suitable for powering a future single-aisle replacement for the 737. Rolls-Royce and Pratt & Whitney are likely to respond to the RFI with geared, ducted turbofans, which they are proposing to Airbus for its next-generation single aisle (NGSA). CFMI will likely respond with a ducted engine based on technology from its Revolutionary Innovation for Sustainable Engine (RISE) unducted open fan program.
Each engine OEM has a vision for future engines (open fan, ducted fan, geared fan), but is each company also developing an alternative at the same time? PW’s sister company, Pratt & Whitney Canada, has publicly disclosed its development of an Open Fan engine for a new 70-100-seat aircraft designed by the start-up company
