Secret American aircraft Celera 500L made its first flight

An experimental promising American aircraft Celera 500L, developed by Otto Aviation, made its first flight. According to The Drive, the plane took off in Victorville in California.

The Celera 500L aircraft, developed by the American company Otto Aviation, most likely completed its first flight. However, since all data on the aircraft is classified, this information may be unreliable, and the flight itself may already be the second or third. Details of the tests are unknown, except that the flight itself took place in early November in California at Victorville.

In May, the 2019 of the vehicle undergoing testing was spotted at an airport in Southern California. At the same time, information about the characteristics of the new product and even about its creator Otto Aviation Group, which has been working on the project in a secret mode for about ten years, is still extremely limited.

A promising aircraft has an experimental registration of the Federal Civil Administration aviation USA N818WM. The fuselage of the aircraft resembles the shape of a bullet or air bomb.

Celera 500L’s flight speed is estimated to be 460-510 miles (740-820) per hour, altitude up to 65 000 feet (19,8 km), fuel consumption - gallon (3,8 liters) per 30-42 miles (48-68 km) . In comparison, the Pilatus PC-12, a popular lightweight single-engine turboprop, has a ceiling of 30 000 feet, cruising speed of just under 330 miles per hour and consumes an average of about a gallon on 5 miles of travel. As a result, Celera 500L performance is at least 10 times higher than existing light business jets with similar capabilities.

Celera 500L is designed according to the classic aircraft design. A Raikhlin RED A03 turboprop engine with up to 500 horsepower is installed in the tail of the aircraft. with a pushing five-blade propeller.

Limitations are given to it by a turboprop engine with power (!!! ) 500 l from. Does it bother you? Take, for example, the Lockheed U-2, an American high-altitude reconnaissance aircraft, which climbed to such a height. So he had turbojet. There is a difference?

[Hog]

Turbojet and turboprop have a lot in common, this is not a piston for you (and even they climbed 15 km)

[Demon_is_ada]

You are deeply mistaken A propeller in the form of a screw at such a height ... and even at such a speed ... this is definitely a scam, or an advertising campaign in the form of - discounts of 100500 percent !!! Of course, you can create it, purely technically, only the efficiency of the engine will be many times higher. The proportions of the aircraft have long been verified, that is, the size of the wings as the length, area, size of the propellers as a result of the appearance, you can determine the purpose of the aircraft, flight altitude, speed, etc.

[Hog]

It may not be possible to achieve these performance characteristics with a screw propeller, but they at least want to achieve them (and see if it works or not).
PS: And here we recall the NK-12 engine.

[Demon_is_ada]

Yeah, I want the same thing. So what's new? Take a classic glider (towed aircraft), stick an economical engine (ideally diesel) and you will see something like that in the picture , only this pot-bellied ... it will be a non-high-speed and low-altitude aircraft, but economical, it is impossible to combine all the declared characteristics ...

As the power plant used 12-cylinder aviation diesel engine with multi-stage turbocharged RED A03. Two units are listed on the patent application, but there is only one on the FAA card. This motor is installed on Russian Yak-52 and Yak-152 aircraft. But something does not give such outstanding characteristics, so all this is propaganda nonsense.

[Dikson]

Maybe the second engine is in the fuselage and works as a supercharger-compressor of air at high altitude for the main one?

[Vladimir16]

Of course have. This limitation is called profitability.
A civilian aircraft was created for profit.
Who will climb to a height of 20 km with a "turbofan"?
With such speed and air density at an altitude of 20 km, this fan will do what?

[Hog]

Say it Tu-95)
But in fact, nobody said there that the turboprop engine would be on the serial.
This is a theoretical opportunity and schema.

[orionvitt]

An aircraft with such a huge frontal resistance (judging by the photo) cannot be economical. Unlike TU-95, which was "squeezed" as soon as possible. As well as TU-16.

[Hog]

So you decide what the problem is in the screws or drag?
At altitude, air is discharged and drag is minimal.
And I said about the TU-95 because of its engines (which do not create a large part of the thrust by a screw).

[orionvitt]

Quote: Hog

And I said about the TU-95 because of its engines (which do not create a large part of the thrust by a screw).

[Hog]

Read specifically about the NK-12 (very surprised).
"Specialist", I'm afraid it's about you.

How can a civilian turboprop aircraft have a ceiling of almost 20 kilometers and reach a speed of 820 kilometers per hour!

The Tu-114 civilian turboprop aircraft had a maximum speed of 880 km / h, although the ceiling was only 12000 m. This is with the technology of the 50-60s., For half a century, the science of flying aircraft heavier than air has stepped forward very strongly, along with design ideas and technologies. And there are no restrictions on the speed and altitude for civilian aircraft. If you can do it, you cannot do it, no one, no one limits it.

[SRC P-15]

If this "barrel" is so pot-bellied, does it mean that they are going to stuff something into it? A swarm of minidrones? But what: from a height of almost 20 km, these babies can make a lot of noise. Moreover, if this swarm is controlled by "AI".

It would be nice to know the mass of this miracle of technology. Because the power of four NK-12 Tu-114 in total was 60000 hp at 164 tons of normal take-off weight.

[Servisinzhener]

I think this is a typical American trade ploy. Yes, he can climb 20 km, and develop 820 km / h. And even spend a halon for 42 miles. But where it is not indicated that he can do all this at the same time. And about the fact that at the same time he will obviously not be hammered and should not speak.

[abc_alex]

Quote: Hog

1) Yes, yes, of course)

No wait. An interesting question. Lift is created by the pressure difference between the lower and upper surface of the wing. This difference can be created by geometry, or by the formation of a vortex "bundle".
The geometry of the fuselage is clearly not create lift. Whirlwinds?
Do you see a vortex formation system at this barrel? Me not. Moreover, the air intakes are on top, which means that no vortices should be there in principle - this will reduce their efficiency. And yet, the wing provides some kind of but air retention on the lower surface, although there is a problem of air flow around the end elements. And this body will flow perfectly around as soon as you create a pressure difference, it will immediately equalize ...

Explain how?

From the text of the article:

In the tail of the aircraft is installed turboprop engine Raikhlin RED A03 power up to 500 hp with a pushing five-blade propeller.

Something ducks flew in the fall.) Actually, the RED A03 is not a turboprop at all. This is a German aircraft piston 12-cylinder V-type four-stroke water-cooled diesel engine manufactured by Raikhlin Aircraft Engine Developments, founded by our former compatriot Vladimir Raikhlin. Its modification (RED-A03T), the production of which seems to have already been localized in Russia, is going to be installed on the Yak-152 and the Altair UAV. The Russian holding Finam has invested in the development of RED A03.

If the flight data is real, then this is a revolution in efficiency.

[askort154]

Celera 500L’s flight speed is estimated to be 460-510 miles (740-820) per hour, altitude up to 65 feet (000 km), fuel consumption - gallon (19,8 liters) per 3,8-30 miles (42 -48 km).

You can assume anything. But to accelerate this "melon" to 820 km / h, on a turbo-screw engine with a capacity of 500 l / s., Or drag it to 19,8 km, the fuel consumption is 6 liters per 100 km ??? Munchausen -

[Town Hall]

And what is the air density at an altitude of 20 km?

[askort154]

Town Hall ..And what is the air density at an altitude of 20 km?

If we take the standard = 760mm / r.st at the surface of the Earth,
subtract the received number from it - taking into account the reduction - 1 mm. 110 meters high.
This will be the pressure at a given height.
Example:
20 000m: 110 m = 181,8
760 - 188.8 = 578,2 mm / r.st - this will be the pressure at H = 20 km.
But if it’s from a specific area, then it is necessary to take pressure not standard (760), but true at a given point.

[Town Hall]

Table. The averaged density of the atmosphere at various heights above sea level. At sea level, the temperature is taken equal to 15 ° C, and a pressure of 101325 Pa = 760 mm Hg.

The density of the atmosphere at different heights above the ground.
Height, km Density, kg/m3
0 1,225
0,05 1,219
0,1 1,213
0,2 1,202
0,3 1,190
0,5 1,167
1 1,112
2 1,007
3 0,909
5 0,736
8 0,526
10 0,414
12 0,312
15 0,195
20 0,089
50 1,027*10-3
100 5,550*10-7
120 2,440*10-8

As you can see, the difference in air density between 10 and 20 km is 5 times approximately. Add a much better aerodynamics, a better wing, probably a lot less mass due to composites, an improved engine. Plus, for sure, the indicated flow rate refers only to cruising altitude and speed. And no fantastic miracles, and quite achievable indicators

[askort154]

Town Hall .... And no fantastic miracles, but quite achievable indicators

Theoretically possible. But practically, I don’t remember single-engine,
a propeller plane flying at H = 20 km. And further:
- standard pressure 760 mm / st. reduced to the level of the Baltic Sea and conditionally taken Н = 0 m., at T nv = + 15 * C. Below the airfields, practically none. And this means that our calculations here are no longer accurate. And most importantly, we don’t know the take-off mass and quality of this aircraft.

[Eule]

The "physiological boundary of space" is 19 km, that is, the height at which a person without a spacesuit will instantly die from boiling water in the tissues. That is the pressure at which water boils at 36 degrees. 19 mmHg if sclerosis fails

[Horon]

The screw also needs to be repelled from something; if the air density drops, the propulsive force of the screw also drops. An increase in revolutions is also not an option, going beyond supersonic in the zone of rotation of the blades forms a zone of low pressure, which in turn, again, will lead to a sharp decrease in propeller thrust.

[Town Hall]

Quote: Horon

air density drops, then the propulsive force of the screw falls

Linearly?

[Horon]

For the screw what, the separate environment exists? These are interconnected parameters! It's not about the impossibility of achieving this speed. Alas, here I am not an expert. The only question is the incorrect connection between the speed and density of the air when using screws as a mover. Density will affect both lift and friction and traction at the same time!

[Town Hall]

Quote: Horon

These are interconnected parameters!

Once again. If the air density drops 5 times .. the pull force of the screw also drops 5 times or less or more?

[Horon]

Most likely 5 times and fall.

[askort154]

Town Hall Once again. If the air density drops 5 times .. the pull force of the screw also drops 5 times or less or more?

The question is not correct. Without graphs - "curves of the required and available rotor thrust" depending on the speed, the pitch of the propeller and the air density on the H flight, there is no point in discussing here.

[askort154]

Horon ...The screw also needs to be repelled from something; if the air density drops, the propulsive force of the screw also drops. An increase in speed is also not an option, going beyond supersonic in the zone of rotation of the blades forms a zone of reduced pressure, which, in turn, will again lead to a sharp decrease in propeller thrust

Totally agree with you. That is why we made coaxial propellers for Tu-95 and Tu-114. Only due to the alignment of the propellers, they have a decent ceiling and speed. Not one "turbo-rifle" has such indicators anymore!

[Hog]

Well, so your conclusions are not far gone

[Horon]

Unless the specified motor is auxiliary! There are too many "secrets" in this plane and at the same time the engine parameters are indicated! I think that for specialists the aerodynamic parameters and engine power will immediately say a lot, but the declared economic parameters exceed those values ​​that can be obtained from the known data! So either the Americans have invented new physics, or they merge only those parameters that don’t tell the others anything - a snag to distract attention!

[Horon]

And getting power of 500 hp / ~ 430 kW with 8 liters of fuel, even at 100% efficiency, is somehow complicated!

[Demon_is_ada]

yeah ... 1 liter solariums like kerosene somewhere around 13 kW / h in theory, we multiply by 8 we get 104 kW at a flow rate of 8l / h at an efficiency of 100, 500 it will be 38,5 liters per hour or 10 gallons, at a speed of 800 on one gallon of 80 km at 100 percent efficiency of dvigla and the screw

[Horon]

Yes, I also estimated the thermal power of different types of fuel and also did not approach 500 hp at 8 liters of flow.

This is probably the "best buy omerica technology in the world" Hollywood and idle talk ... thirst is nothing, our advertisement is fse, people hawks with swallow ... I just want to sing in a frenzy - Omerika, Omerika filled with amber light and beat in the lap ...

There are too many secrets, and what they feed the public is not a fact is the truth! Everything may differ from what has been said from unsaid, to what is said completely opposite from the existing. Perhaps he has an electric drive for a propeller, or the power of a lie, or fuel consumption, or some kind of a fundamentally new type of mover, and the screw is only for looking away! Information is thrown into the media in order to stir up interest, but does not carry any real technical information that allows you to make at least some real assumptions.

In the rear part of the aircraft, a Raikhlin RED A03 turboprop engine with a capacity of up to 500 hp is installed. with a pushing five-blade propeller.

Just in case, from Wiki:
RED A03 is a German aviation piston 12-cylinder V-type four-stroke water-cooled diesel engine with a capacity of 6134 cc, with a fuel system of the type of commontrail, direct injection, a turbocharger and a gearbox with a transmission ratio of 1: 1,78, with an electronic control system. The engine was developed by RED Aircraft GmbH.
Engine developer Vladimir Reikhlin graduated from Kazan Aviation Institute with a degree in aircraft engine engineer. After college, he worked for some time at the VAZ. In the early 2000s, he founded the company RED (Raikhlin Engine Development) in Germany.

It is worth remembering that aerodynamics is a mysterious science. There are a lot of geeks in it. Anyone who unravels the secret of the flight of the May beetle or bumblebee, may well throw off the cost of the flight dozens of times. Why not assume that some secrets of such a flight are open, at least partially? I do not claim that this is so, but the main condition for the formulation of the engineering problem is fulfilled. Cockchafer is flying. Nature solved the problem of moving a relatively large load with relatively small efforts. So this is possible, the problem has a solution.
