December 13, 20232 yr IRL, and would certainly be to build also for XP: Siriusjet - First Hydrogen-Powered Regional VTOL Aircraft. Flying gliders since 1980 Flightsimming since 1992 AMD Ryzen 5600x, 32GB RAM, GPU Nvidia RTX 3060 Ti 8 GB, 1 TB and 500 GB nvme2 SSD drives, HP 27" 60Hz LED monitor @ 1920x1080, T16000, Hotas from old X52 Pro, Saitek Combat Rudder Pro (2010 model)
December 13, 20232 yr If this was a custom design for X-Plane I'd like it, but as a real thing, I need to see it fly and and actually get sold to believe it. Edited December 13, 20232 yr by Bjoern 7950X3D + 7900 XT + 64 GB + Linux | 4800H + RTX2060 + 32 GB + Linux My add-ons from my FS9/FSX days
December 13, 20232 yr Author Yeah, it scares me - I don't believe I would fly in such a vehicle, IRL 🙂 Flying gliders since 1980 Flightsimming since 1992 AMD Ryzen 5600x, 32GB RAM, GPU Nvidia RTX 3060 Ti 8 GB, 1 TB and 500 GB nvme2 SSD drives, HP 27" 60Hz LED monitor @ 1920x1080, T16000, Hotas from old X52 Pro, Saitek Combat Rudder Pro (2010 model)
December 14, 20232 yr A VTOL vehicle powered by 50 CPU fans is theoretically safer than a single engine helicopter. Lose a fan, still have 49 more. Lose the engine, shaft or gearbox, well... 7950X3D + 7900 XT + 64 GB + Linux | 4800H + RTX2060 + 32 GB + Linux My add-ons from my FS9/FSX days
December 18, 20232 yr I am highly sceptical about all these paper designs. Boom also astounds me - they announced Honeywell avionics but they don't have an engine!
December 18, 20232 yr Boom can at least piggyback on NASA a bit. And their prototype is pretty benign. But it is interesting that Virgin said "no thanks". Hydrogen will probably come before full electric does. Energy densities just aren't there yet and H2 is the next best thing. So at least they're thinking in the right direction. 50x in the right direction no less! Friendly reminder: WHITELIST AVSIM IN YOUR AD-BLOCKER. Especially if you're on a modern CPU that can run a flight simulator well. These web servers aren't free...
December 18, 20232 yr Electric is more off the shelf though. Just get the infrastructure on and off the plane done and sit out whatever evolvement direction battery technology takes. Hydrogen may sound more attractive, but integration into airframes is still a big head scratcher considering the pressures involved in storing it. As with cars, I'm all in favor of something modular. Electric drive, but pick between power generation from a battery, fuel cell or combustion engine (maybe also gas turbine, lol). 7950X3D + 7900 XT + 64 GB + Linux | 4800H + RTX2060 + 32 GB + Linux My add-ons from my FS9/FSX days
December 18, 20232 yr Off the shelf or not, full electric for anything larger than small regional doesn't make sense for the majority of flight profiles. Hybrid electric is more plausible but still only for small airframes. Battery energy density will need to be slightly better than JetA. Even with the more efficient transfer of energy, you still have to account for the fact that battery weight doesn't burn off during flight as with fuel. It isn't that H2 sounds more attractive. It's a necessary alternative if short time frames (decades) are the goal. Unless some government decides to reveal their secret battery tech being tested at Area 51... or we just decide to wait another 80 years till battery fully catches up.
