Rolls-Royce tests hydrogen-fueled aircraft engine in aviation world first
- m-watson 4y agoA few other resources because this one seems to read just like a PR: https://arstechnica.com/cars/2022/11/rolls-royce-tests-hydrogen-fueled-aircraft-engine-in-aviation-world-first https://arstechnica.com/cars/2022/11/rolls-royce-tests-hydro... https://www.reuters.com/business/aerospace-defense/rolls-royce-successfully-tests-hydrogen-powered-jet-engine-2022-11-28/ https://www.reuters.com/business/aerospace-defense/rolls-roy... https://www.bbc.com/news/business-63758937 https://www.bbc.com/news/business-63758937 https://simpleflying.com/rolls-royce-hydrogen-tests-turbine-engine/ https://simpleflying.com/rolls-royce-hydrogen-tests-turbine-...
- simonblack 4y agoSure it can be done. But the payload would be non-cost-effective. Won't happen in practice. can be started up and run at low speed = "lack of thrust" Also, liquid hydrogen takes up around four times the space as the same volume of kerosine = no space for passengers. (There is a practical limit to the physical size of aircraft in today's world. To go larger, we'd need to scrap the existing airtports and rebuild with new larger expensive ones.)
