Otto Aviation Unveils New Celera 500L Aircraft with 40% Lower Carbon Emissions
I have seen some YouTube videos as well, as well as Otto Aviation's website. Apparently, this thing "has a fuel economy of 18 to 25 miles per gallon while having an impressive cruise speed of 450 miles per hour and a range of 4,500 miles". The engine is a six litre, 500HP diesel V12. There are no specifications of size and weight anywhere. The aircraft can hold six passengers, and there is room in the cabin for a six foot person to stand upright.
Does any of this sound believable? A P[‑]51 Mustang, with laminar flow wings, has a maximum speed of 440mph on around 1500HP. These speeds are approaching the capabilities of propeller driven aircraft. Mustangs are exceptionally efficient. Other 450mph aircraft, like Spitfires, Thunderbolts, Corsairs, and Hornets, use over 2000HP.
