According to foreign news agency New Atlas, Otto Aviation airlines claim that its quirky-looking Cerera 500L “bullet aircraft” is “the biggest thing in the aviation and travel industry in 50 years” and that its ultimate fuel economy makes private flights as affordable as regular commercial air travel.
Otto Aviation claims that the Celera 500L has fuel economy of 18 to 25 miles per gallon. By contrast, similar jets have fuel economy of 2-3 miles per gallon. In addition, the A03 V12 internal combustion engine significantly reduced its operating costs, estimated at $328 per hour, while Otto said the operating costs of similar jets were about $2,100 per hour. Therefore, its fuel consumption is 1/8 of that of similar aircraft, and the operating cost is about 1/6 of that of similar aircraft.
The Celera 500L’s spacious cabin can carry up to six passengers and offers superior legroom for a range of up to 4,500 nautical miles – more than double the range of theCitation CJ3 plus jet. That means it only needs half a tank of oil to fly from Los Angeles to New York. It’s almost as fast as the Citation, which has a top speed of nearly 480 miles per hour, and the C500L, which has a maximum cruising speed of more than 460 miles per hour and uses a single-propeller propeller.
The Celera 500L’s excellent fuel economy also gives it a head start in terms of emissions; Otto says it is more than 30 percent above the FAA’s and ICAO’s target emission standards for aircraft that go into service after 2031. Its 22:1 taxi ratio allows it to ski for up to 125 miles without power, “about three times better than a normal plane.”
Otto says it was able to accomplish all these feats because of its quirky design, which uses a large number of stratum surfaces to create a “smooth airflow layer with little mixing of adjacent layers.” Otto says the Celera 500L offers a staggering 59% reduction in resistance compared to traditional designs of similar size.
This raises the question: if it’s so efficient, why are we seeing it for the first time? What are the other manufacturers’ priorities in wind tunnel design? One possible answer, Otto says, is that these benefits don’t extend up to full-size airliners, and aspect ratios are critical.
Typically, such small aircraft are only associated with very high-end cities, but William Otto Jr., the company’s chairman and chief scientist, said, “In many cases, individuals and families will be able to charter the Cereca 500L at a price comparable to the price of a commercial ticket, but with the convenience of private aviation.” We believe that when the price of private air travel is competitive with commercial air travel, there will be huge market opportunities. “
Otto said it had completed 31 successful test flights with full-scale prototypes, “verifying its operational performance objectives.”
