To fly around the planet in a couple of hours: China creates a hypersonic device based on the development of NASA

X-47A

Chinese scientists "revived" one of the abandoned American developments, intending to create a hypersonic passenger vehicle.

In the United States, the Manta X-47C program was being implemented, within the framework of which the concept of a hypersonic engine, created by a Chinese-born NASA engineer Min Han Tang, was tested. It was phased out in the early 2000s due to technical difficulties and costs. The scientist then proposed to place the power plant not inside the fuselage, but on the sides of the aircraft body.

The engines had to act like conventional turbine jet engines at a lower speed, and then switch to a mode of operation without moving parts, since this allowed for flight speeds five times or faster than the speed of sound. The project was regarded as risky, since there was a possibility of ignition of the engines after switching to hypersonic speed.

According to the South China Morning Post, the Chinese developers nevertheless decided to revive the idea, having received Tan's blueprints, declassified in 2011. They created a prototype device, which they tested in a wind tunnel in Nanjing. It was found that the product reaches speeds of up to Mach 8 and can go into hypersonic flight in the most difficult conditions.

Based on the Tan concept, Chinese researchers plan to build an aircraft by 2035 that can deliver up to 10 passengers to any part of the planet, flying around it in a couple of hours.

The first flight of the X-47A:

And it didn't fall apart. It's already good ..

"They created a prototype device that they tested in a wind tunnel in Nanjing" - Mach 8 and in a tube? Original)))

Yes, it is POSSIBLE to calculate with Chinese SuperCompas !!!!!

[tralflot1832]

Well, the Chinese have worked out technologies for creating a hypersonic engine for American money in the United States. And then Putin trolled: the United States is slightly ahead of China in hypersonic weapons! And who's a sucker?

[spirit]

A sucker will be the one who talks a lot and in the end nothing will fly. The Chinese have recently been talking a lot about their hypersonic developments, but something tells me that half of this is pure propaganda. Until the technology demonstrators really fly at such speeds and this do not fix (Not the Chinese), then you can divide everything by 10

[tralflot1832]

It's enough for me that there is panic behind a puddle, an ordinary unsuccessful launch is already perceived as a hypper.

[Kosh]

If you look at the news, then the Chinese themselves hardly ever talk about their hypersonic developments, and in general they are traditionally very stingy with information about their missile developments. Almost all the information about Chinese tests of various new products, including hypersonic weapons, comes from the Americans, who are tracking the launches. In this case, a rare exception, and even then for the reason that we are talking about the alleged civilian use.

[voyaka uh]

The Chinese are once again very stingy with stories.
And they hide their developments.
Russia is constantly talking about hypersound. Every day - an article about
the fact that Russia is the world leader in hypersound.

[Trapp1st]

Are you talking about the Russian press or something else?

[Aviator_]

It's great that the Chinese have worked out technologies for creating a hypersonic engine for American money in the United States.

There is nothing at all about dvigun. Blown the model in a pipe at M = 8 and that's it. The Chinese have problems with conventional engines, but here is a hybrid of direct flow and turbojet engine.

[dauria]

and here is a hybrid of direct flow and turbojet engine.

Well, any afterburner turbojet has two engines one after the other. Direct-flow trail behind the turbojet.
Even the word "afterburner" is not entirely correct here. It just stuck. But in fact - the inclusion of an additional ramjet engine. And this very "pipe" even harms the turbojet when it does not work.

[Aviator_]

Well, any afterburner turbojet

By no means, you can't get by with the afterburner. The main problem is to ensure combustion in a supersonic flow in the combustion chamber. Up to M numbers less than 5, there is no such problem; traditional combustion chambers with a subsonic flow are used there. At high flight speeds, if the subsonic speed is still left in the combustion chamber, the temperature will be so high that the fuel will dissociate. Therefore, for 40 years now, they have been working out a supersonic combustion chamber for a scramjet engine, but have not yet worked it out.

The Chinese will build.

Up to 8 Machs in this form is strictly civil flight, without maneuvering.

and then switch to operation without moving parts.

I do not observe, from the word "absolutely".
If you believe everyone, then the Urals still exist by a miracle (because 404 are threatened), but China will be more serious. So where are the vidos and the "new physics"?
I also have Super Wanderers, but so what?
They still cannot pass materials science on their 5th generation aircraft engines, but here ...

[Alexander 3]

Direct-flow engines and turboprop - how to combine them? All engines are in the hull, and fuel, equipment, interior, crew.

[Kesha1980]

I'm more interested in this "artifact" - an engine with no moving parts. I am a little familiar with the ionic engine for aircraft (especially its weak power), but what do the Chinese mean? It smells of raving. Not?

[Alexander 3]

Herbert Wells knows for sure.

Well, this is generally golimous nonsense (as young people say). Translation (engine without moving parts) oak, meant scramjet

Probably, this refers to the direct-flow mode. The turbine is turned off and the movement - due to the jet stream, like a rocket.
Unrealistic, ramjet engines are very gluttonous. The flight range will be insufficient. And how to protect passengers from possible overloads? To give out to each compensatory suit? So it's not a fact that it will help.

[Kesha1980]

I also think that until gravitational compensators are invented, the overloads will not allow "to fly around the planet in a couple of hours." A drone for technology testing?

[Pandiurin]

Why should there be overloads?
This is not a maneuvering warhead. For hypersound, as far as I understand, the upper layers of the atmosphere are optimal, say, somewhere, an altitude of about twelve kilometers.
If the device flies mainly in a straight line, the environment is sufficiently discharged, there are no atmospheric phenomena such as rain, hail, thunderstorms.

Are there really going to be overloads?

[Kesha1980]

Nobody has canceled inertia yet. From there, overloads arise. This is not a direct flight - there is an ascent / climb, there is a landing / descent. Otherwise, "2 hours to fly around the Earth" will not be enough - then you will have to accelerate to 20-30 M on the "productive" (in terms of the covered distance) segment of the flight.

Well, this is the journalists' marketing style of presentation, they took and divided the distance into cruising hypersonic speed. And the inertia when gaining speed and altitude will be determined by the engine power in the TRD mode.
It is hardly something outrageous.
Well, in half an hour it will "crawl" to its echelon. The landing approach is also half an hour. This is not a vertical takeoff like that of astronauts, when, due to fuel economy, you need to take off as quickly as possible.
An airplane, unlike a rocket, does not have such a direct relationship.
Slow takeoff, of course, a little more fuel is burned.

Read it, 5 years after the prototype appeared. The Chinese do not publish anything prematurely, secrets at the level of the USSR (who taught).

[Mountain shooter]

Mach 8 will allow you to fly around the earth in two hours. This is approximately 2.5 km / sec = 9000 km / h. From any point to any (20 km each!) But how much fuel is required for such a flight? True, the Chinese technical fairy tales have already been imposed in their teeth ... Russia has launched hypersonic weapons into series ... The Chinese immediately reported - we also have it, and even cooler. Is there?

[Thrifty]

Mountain shooter - you will fly around the ground in 2 hours, and you will wait another 8 hours for the hull to cool down to leave the plane safely ...

[Mountain shooter]

A half ball is enough. and what, the Soyuz descent vehicles are cooling down for two hours? And are they there, poor fellows, sitting waiting? Much less, I suppose ... And even without assistance.

[Thrifty]

Mountain shooter - and you were the first near the descent vehicle with a stopwatch? And, the difference in technology, the plane should not turn out to be disposable!

[Vadim237]

A hypersonic aircraft, before landing, will need to drop the speed to subsonic and below in this interval, the hull will be cooled, especially at altitudes of 25 kilometers, it is cool enough so that you do not need to bother about cooling at all, such a hypersonic aircraft is presented with a combined power plant on hydrogen and kerosene for the first scramjet engine for the second supersonic turbojet engine for acceleration

From anywhere to any (20 km each!)

[Vadim237]

Russia has its own concept of a hypersonic passenger airliner; they promise to take it into the air in 2025.

Let's see who's desires coincide with the possibilities.

[evgen1221]

At 25, yeah, with an elastic band on panties and performed with aliexpress.

[Vadim237]

And why not, the aerodynamic model at TsAGI has already been blown dozens of times in an ordinary and hypersonic tube, and yes, in 2025 they promise to lift the part-type into the air, that is, a reduced copy for practicing technical solutions of materials and everything else - and you have an elastic band from cowards instead of a brain.

[Jvm54]

For a couple of hours? 20000 km / h ... how many swings?

[evgen1221]

How did the Americans strangely declassify the drawings for hyper? Oh nafig. Rather, this scientist quietly copied and after the project was closed in the states (maybe he sabotaged it on purpose), he just returned home with the feeling that he had poured amer and calmly completed what he had begun. Well done if so. I got it right.

[aries2200]

Another Chinese propaganda promise.

[Illanatol]

Quote: Vadim237

during this period, it is the case that will be cooled, especially at an altitude of 25 kilometers, it is cool enough so that you don't have to bother about cooling

There, the air is rarefied, heat transfer is unimportant (thermos effect). The cladding will have to withstand strong gradients and changes in temperature. In short, not everything is so simple.

It is not a fact that the structure will withstand. Let us recall what happened to the Columbia (in the stratosphere - also on hypersound), when, due to wear and / or negligence, its thermal protection failed. How many times has Columbia flown?
3. Well, what about the flight range of this "miracle of hostile technology"? Enough to fly around the "half ball"? And the prices for the ticket, would you like to announce it?

Is there a difference between a passenger liner and a super duper yacht for an eccentric lone billionaire?

So who will let civilians on such a pepelats. According to its characteristics, it is a strategic hypersonic bomber. No country has anything like this in the Aerospace Forces, air defense is also questionable whether it can fight something like that, only some countries have something.

If the Chinese are developing this, then this is a bomber under the guise of a "business jet" for the duration of technology development.

For businessmen, such birds may be twenty years from now, when technology spreads around the world. And the warriors will have something more abrupt, well, like the speed is not less, but the UAV with AI and the maneuvering is intense.

Such systems should be fought not by air defense, but by missile defense.
And it is better then to create a space bomber using the concept of air launch, as suggested by Lozinsky. Better - unmanned, on duty in orbit with ammunition "vigorous-batonov".

Why fly around the Earth in two hours with running engines, if it is possible, having entered orbit, to fly around in an hour and a half without using fuel? With access to orbit, it will be cheaper.

It's easier to shoot down in orbit. there is not much maneuver
