    The original "I don't know it all" of aviation.
    https://www.thedrive.com/the-war-zo...volutionary-celera-500l-aircraft-may-fly-soon

    More than two years after The War Zone was first to report on a mysterious bullet-shaped aircraft appearing at the Southern California Logistics Airport near Victorville, a refined version of the plane has conducted taxi tests and looks to be getting close to its first flight. Even though much about its design and purpose remain unclear, we do know now that the aircraft, which is called the Otto Aviation Celera 500L, is definitely focused on potentially game-changing high-efficiency flight that has the potential to disrupt the aerospace marketplace.
    The author also comments on the patent claims...

    The patent goes on to describe a notional aircraft that would cruise between 460 and 510 miles per hour at an altitude of up to 65,000 feet, yielding a fuel efficiency rate of between 30 and 42 miles per gallon. To put this in perspective, the Pilatus PC-12, a popular light, single-engine turboprop aircraft has a service ceiling of 30,000 feet, a cruising speed just under 330 miles per hour, and still burns, on average, 66 gallons of jet fuel per hour, for a fuel economy of roughly five miles to the gallon. Even going to a Learjet 70, which has similar speed performance to what's stated in the Celera patent documents, but still nowhere near as high a ceiling, we are talking about roughly three miles per gallon of gas at cruise. So, Otto Aviation is talking about performance that is at least 10 times more efficient than existing light business jets with similar cruise capabilities.

    500 hp in an airframe that big. My prediction is 230 kts cruise at FL250...and they’re gonna scrape the crap out of that bottom stinger.

    Who flies first, Celera or Raptor?

    With 130 kts stall speed.

    I don’t know, I think the Raptor might fly with the next couple weeks. I believe they said their test pilot was to show up this weekend.

    Well, at least there will be Otto Pilot jokes.

    There are just too many unproven components on that plane. The engine being the biggest, IMHO. I don't know enough about that redrive system, but a single belt driving the prop seems... something. And not a good something. If he had gone with a Continental or Lycoming, I think they would already be flying.

    A propeller at 65,000 ft?

    That anybody actually believes this is a testament to the decline in our public education system.

    (btw, I believe I have a 100 mpg carburetor somewhere in the basement. Fits any pre-'73 Oldsmobile or Buick, as I recall. It's a real collector's item because the oil companies apparently bought up all the rest of them. ;) )

    The test pilot looked at the Raptor this weekend and took a pass - Peter posted a long video on YouTube with the details yesterday.

    Yep. Just got done watching it. Bit of a setback. Three main issues. 1) possibly some aero elasticity with the winglets/ tip sails being so long. 2) possible pitch control issues with the Fowler elevator. 3) single ECU.

    I'm not sure how you get that goofy looking egg off the ground with one propeller on the backside

    I have to think that the propeller on that one will be seeing a terribly disturbed airflow.

    This thing reminds me of the Lear Fan... a cool bird but ultimately was a failure due to fuselage crack pressurization issues and the FAA not liking the reliability concerns of the two turboprops feeding via gearbox into one drivetrain

    The stinger needs a wheel grafted on to it.

    All minor issues, and easily solved with hope and wishful thinking.

    All turbofan jets are essentially propeller driven, and routinely fly in the fifties.

    The Avanti is fast, reliable, beautiful, and available. That last one is kind of important.

    "Even assuming huge advances in battery technology, with batteries that are 30 times more efficient and "energy-dense" than they are today, it would only be possible to fly an A320 airliner for a fifth of its range with just half of its payload, says Airbus's chief technology officer Grazia Vittadini."
    Yup..

    Why you will only ever see this as a niche product for local routes.. a novelty really

    How much down time does Cape Air plan to have between flights?

    I also wonder what kind of considerations have been made for the source of the electric energy charging the planes .. most of our energy in the United States come from gas, oil, and coal.. so no free lunch. And while it may be cheaper now, I can imagine that if all our planes start being charged up from the grid we will see differences in pricing for the that

    No free lunch!

    Cool to see the tech though
