Boom recently lost its engine partner for the Overture supersonic jet, and neither are other major engine manufacturers interested in the project, insider has called. After Boom had already signed an “engagement agreement” with Rolls-Royce for supersonic jet engines in 2020, the latter announced last week that it had left the project. Now other major engine manufacturers, including Pratt & Whitney, GE Aviation, Honeywell and Safran Aircraft Engines, have announced FlightGlobal They are currently not interested in supersonic aircraft.
Boom said the project is still on track, however, and will announce an engine partner soon. “We can reiterate our intention to announce Boom’s engine partner selection and transformative approach to reliable, cost-effective and sustainable supersonic flight later this year.” Boom told insider. The company has ordered 20 aircraft from American Airlines and 15 from United. Plans are to build a factory in California and fly passengers by 2029.
For its part, Rolls-Royce said that “after careful consideration… [we] have determined that the commercial aviation supersonic market is not a priority for us at this time and will therefore not proceed with any further work on the program at this time.
After careful consideration, Rolls-Royce has determined that the supersonic commercial aviation market is not a priority for us at this time and will therefore not undertake any further work on the program at this time.
There are a limited number of other manufacturers capable of developing a supersonic jet engine and all the big ones say it’s not in their plans. Honeywell, Safron and GE closed the idea, while Pratt & Whitney stated that supersonic travel is “tangent” to their business.
Pratt & Whitney cited efficiency as a problem for supersonic jets, and other manufacturers said they were focused on reducing fuel consumption. Given the criticism of air travel’s contribution to global warming, this is the primary direction for the industry right now. In addition, the International Civil Aviation Organization (ICAO) recently criticized supersonic travel, stating in a report that it would use 7 to 9 times more fuel per passenger per kilometer than subsonic aircraft.
Boom has announced that it will offset its carbon footprint by using Sustainable Aviation Fuel (SAF). However, the ICAO report states that this would be a poor use of scarce SAF fuels, given the high fuel consumption compared to a normal jet. It also found that “the high cruising altitude of supersonic significantly increases the residence time of emissions”.
