Another red-flag to me is the diagram labeling "proprietary superalloys". This implies more than one new metal composition, which by definition is unproven? So a new metal, in a new engine, in a new airplane.
- sandworm101 10mo agoAdd to that the "titanium" lable. Nothing is pure titanium. It is all alloys, most of which are "proprietary". Inconsistant technical terminology within a diagram is a huge red flag imho. >> Legacy turbines need huge quantities of water for cooling to avoid thermal derate in hot environments Yup. Turbine-powered helicopters famously haul big tanks of water around when flying in hot environments. Heat is a problem, not a game changer.
- mmaunder 10mo agoIt's exactly what existing manufacturers are doing. What they're calling "legacy". Here, watch this which goes into detail on existing superalloy tech used in todays engines: https://youtu.be/QtxVdC7pBQM?si=coIv6w0N2BZ4EOTK&t=1027 https://youtu.be/QtxVdC7pBQM?si=coIv6w0N2BZ4EOTK&t=1027 and And here's how single crystal blades are already being used in today's engines: https://youtu.be/QtxVdC7pBQM?si=XpnAgVH1QmLiX0g0&t=1650 https://youtu.be/QtxVdC7pBQM?si=XpnAgVH1QmLiX0g0&t=1650
