> 1800C° turbine inlet temperature sounds completely unrealistic the current max is 1600C with cooled monocrystal blades. The 1800C seems to be a worthy goal post in this situation. More advanced cooling and/or say some tungsten composite for example. Even if they end up with "just" 1700C it would still be great. Wrt. 6th gen in general - it looks what everybody is doing is just targeting the goal posts just a bit behind the 5th (some are even basically skipping the 5th). That actually would give us the 5+th gen. The true 6th will have totally new capabilities plus of course all this advanced 5+th tech as a base. Currently it seems to me that autonomous/AI will be that new capability (on top of much improved engines, radar/sensors, stealth body). This will also as usually differentiate top players possessing the next gen capabilities from the rest wannabes.
