The Potentially Revolutionary Celera 500L Aircraft Officially Breaks Cover

Otto Aviation aims to disrupt the aviation landscape with a design that flies at jet speeds, but uses a fraction of the gas, and has more range.

Otto Aviation's Celera 500L has officially come out of the shadows and the company has now outlined its vision for the potentially revolutionary high-efficiency aircraft, including possible unmanned variants and military versions configured for intelligence, surveillance, and reconnaissance missions. The War Zone was first to report on this unusual bullet-shaped plane after it was first spotted at the Southern California Logistics Airport near Victorville in 2017 and has been following its secretive development very closely ever since.

"Innovation at its core is solving a problem without conventional bias. Our goal was to create a private aircraft that would allow for direct flights between any city pair in the U.S. at speeds and cost comparable to commercial air travel," William Otto Sr., the Chairman and Chief Scientist of Otto Aviation, said in a statement. "In many cases, individuals and families will be able to charter the Celera 500L at prices comparable to commercial airfares, but with the added convenience of private aviation. We believe when the price of private air travel is competitive with commercial air travel, an enormous market opportunity will result."

Otto Aviation says the Celera 500L had a maximum cruising speed of at least 450 miles per hour and a range of over 4,500 miles. It also has impressive fuel economy, achieving 18 and 25 miles per gallon, according to Otto Aviation. A traditional business jet with similar capabilities to the Celera 500L, including its six-passenger capacity, typically burn a gallon of fuel for every two to three miles of flight, making Otto's design dramatically more economical, as well as more environmentally friendly. The company says that the Celera 500L will have an unbelievably low per-hour flight cost of just $328.

The aircraft's teardrop shape also provides a roomier main cabin compared to many similarly-sized business jets, as well as small turboprops. This will improve passenger comfort for long-duration flights. Otto notes that a range of 4,500 miles, together with a typical takeoff run of around 3,300 feet, means that the Celera 500L will be able to fly between virtually any airports in the United States without need to stop to refuel.

Otto's goal is to have achieved FAA certification by 2023 and then have a manufacturing facility delivering actual production Celera 500Ls to customers by 2025.

All told, after years of reporting on the mysterious aircraft, we are certainly very excited to see Otto Aviation's Celera finally break cover in an official capacity. The aircraft certainly represents an incredibly ambitious and disruptive set of capabilities that could significantly change the course of aviation and transportation overall.

Getting such an exotic concept into a flying form is an incredible feat in itself for the Otto Aviation team, one that requires large resources and comes with considerable high-risk, to say the least. We look forward to seeing how high the Celera idea can fly from here.

I wouldn't have put thought into it just a few month ago, now my first thought is "nice, when can I fly it in flight simulator".

What's the catch here? Things like this just don't pop out of nowhere, especially in the aviation industry.

Or, as I like to put it, you can't beat physics, so why hasn't this super-efficient design appeared in other modern aircraft?

Seems like it'd be far less environmentally friendly to have a bunch of these vs one big plane not to mention the logistics of running them all

A single diesel piston engine is going to get much better efficiency than twin jet turbines. This thing will never be rated for open water because of that.

Also rich people don't give a fuck and would rather have the redundancy and performance of jet engines.

They are comparing it to charter jets, which hold six to eight people.
they're comparing it to similarly sized jets. so i don't know, how does math work?
Still seems like they want to push it as an alternative to commercial travel that most people use though

I guess the speed is the catch ?

One tiny turbo prop can go fast like reaction engines ?

well, its in the article.

This and aircraft's other notable performance characteristics are made possible in large part due to its highly aerodynamic overall laminar flow shape, which produces approximately 59 percent less drag than existing similar-sized, more conventionally-shaped aircraft. It's high-efficiency Raikhlin Aircraft Engine Developments (RED) A03 V12 piston engine is another important part of the equation. The A03 has a multi-stage turbocharger and can run on Jet A1 fuel, as well as kerosene or biodiesel.

Germany-based RED touts the engine as a very high-efficiency design with low fuel consumption and very good reliability over existing piston engine designs with equivalent horsepower ratings. "The Celera 500L's aerodynamic airframe requires significantly less horsepower to achieve take-off and cruise speeds, allowing for a more fuel-efficient power plant [the A03] to be utilized," Otto's website says.

One of seven different patents Otto holds that apply to the Celera 500L also describes the aircraft's novel exhaust system with a heat exchanger to provide an additional boost in thrust. The aerodynamic shape also gives the plane excellent handling even if the engine fails, adding an additional margin of safety.

Well, 737s and other airliners are around 80 - 100 mpg per passenger (~0.5 mpg * 200 passengers), and this looks to be around 120 mpg per passenger if I'm doing the math right. The airliners benefit from certain efficiencies of scale, so the Otto getting that kind of efficiency while going that fast while being that small is extremely impressive.

This might be one of the best moments in a long time to sell a small commercial airplane, good luck finding enough pilots though.

Oh shit sorry, yeah, I misread. I was conflating "take this as an alternative to a commercial flight" to the MPG comparisons. Thanks for pointing it out all. If this thing is real then it's very impressive.

Can they make one of those the size of a 747? Then these dudes will have a true market disrupter on their hands.

Big-tube commercial aviation is poised to be a rolling shitshow for a good number of years going. I've seen some voices mention that small aviation is actually a better bet in the short-to-mid term. IF they can get costs down, like Otto Aviation claim.

18-25 mpg to move 6 people or 2-3 mpg to move 200.

How does math work?

Others have pointed out why this isn't correct but (with the right numbers) it's actually a useful way to look at it.

To compare fairly we can use passenger mpg. The average commercial airline gets about 64 and the best (Norwegian) gets 103.

These planes claim to get 108-150 passenger mpg on a full flight. It'll be less in practice but it still stacks up very well.

This sounds incredible, where's the catch?
The catch is it's super niche and still won't be accessible to normal people for a reasonable rate whatsoever is my guess. So it's basically meaningless for pretty much anyone outside the elite.

It's got a passenger capacity of 6. So it's really only impressive from a private jet to private jet comparison.

Actually Turboprops can reach ridiculously fast speeds, there was a military test jet back in the 50's with one where they mated a ramjet turboprop with a supersonic propeller, well the propellor broke the sound barrier... problem is the side effects to the pilot... pavement, nearby life, control tower equipment and staff, yeah. apparently an object that small on the ground putting off 3 repeated shockwaves in quick succession is extremely dangerous, caused a nearby crew chief was too close to pass out. Needless to say it was grounded after the first test flight. It is still considered the loudest aircraft ever made.Say hello to the XF-84H Thunderscreech:

They were starting to reach their real potential when jets started phasing them out but there's still been experiments over the years just not many large scale ones. But there are designs that are more efficient but comparable in power to jet engines

There are quite a few unemployed right now due to the virus and Autopilot exists

I wonder if we'll see some version of that pop up in drones.

The term is wide body and yes, we won't see a resurgence in wide body for at least 5 years minimum.

Another thing is people who uses bizjets value speed the most and bizjets usually fly higher and even faster than airliners.

This is a pretty neat concept though and hope to see more.

Ah, yeah, wide-body. Though admittedly there are some large narrow-bodies (ex. A320) which are also feeling the pinch due to reduced pax numbers.

Another advantage of a plane like the Celera is the ability to operate off shorter runways, like those found at small general aviation airports, that are mostly off-limits to airliners.

EDIT: oh, spotted an interesting tidbit:
One of seven different patents Otto holds that apply to the Celera 500L also describes the aircraft's novel exhaust system with a heat exchanger to provide an additional boost in thrust.

So it seems like Otto have installed Meredith effect thrusters on the radiators, like the one originally found on the P-51 Mustang.

The Potentially Game-Changing Celera 500L Has Finished Its First Round Of Flight Tests

The company behind this unusual design, Otto Aviation, says the tests show the aircraft is on its way to meeting very ambitious performance goals.

message-editor%2F1637195455317-celera500lproductionillustration.png


Otto Aviation says that it has finished the first phase of testing its potentially revolutionary high-efficiency Celera 500L aircraft, which the company officially unveiled last year. The prototype has now flown approximately 51 flight hours across 55 individual sorties, including at speeds over 250 miles per hour and at altitudes up to 15,000 feet, the company said in a press release today.

"The data from our first phase of test flights shows that we are on the path to achieving our goals for the aircraft," William Otto Jr., CEO of Otto Aviation, said in a statement. "We couldn't be more excited in this step toward our mission of having a production aircraft in 2025 and we look forward to beginning the next phase of development where we will take the aircraft to higher altitudes and higher speeds."

Otto and his company believe that the Celera 500L's design, with its tear-drop "laminar flow"-optimized shape, long and slender wings, and high-efficiency multi-fuel piston engine, combined with a flight profile intended to make the best use of the plane's features, will inaugurate a revolution in low-cost air travel. The firm's website refers to this as the "air taxi model."

"Several flights reached airspeeds of over 250 mph at altitudes up to 15,000 feet which projects to an airspeed of 460 mph at 50,000 feet," Otto Aviation release said. In the past, the company has said it hopes the aircraft will have a range of at least 4,500 miles and be able to get 18 and 25 miles per gallon of fuel. Its target cost per flight hour is just $328, a fraction of the cost of flying comparably sized turboprop aircraft or business jets.

While the Celera 500L is still very much an experimental design, Otto Aviation already has already laid out plans for a larger Celera 1000L and has openly discussed potential cargo-carrying and military applications for its designs. Its website talks about the potential for unmanned derivatives and versions with hybrid-electric propulsion.

It very much remains to be seen whether Otto Aviation will be able to meet its ambitious goals. There are some that say the company's claims will be extremely challenging if not impossible to achieve.

If it can, the Celera 500L, and future designs based on it, could easily be game-changing on a number of fronts.
